PPL-ASEL Checkride

Aviation, , , , , , , , , , , , , , , , , ,

Last week I called my DPE as previously discussed and got a cross country from KLHM to KMRY for planning. Also, I got the weight and balance details which I worked out in advance. Otherwise, I was asked to prepare per the ACS.

I arrived at Lincoln last evening and stayed overnight. Lincoln airport charges a $5 transient parking fee for overnight tie down. You can pay at the self-service box on the ramp. You can get an Uber from the airport to one of the local hotels. I had tried calling the airport twice to find out the availability of courtesy cars but only reached their voicemail.

My checkride started this morning at 9am. I met the DPE at their hangar. DPE wanted to start off by understanding how I got into flying and what I expected to do with the license. Since I’m interested in volunteering, DPE suggested I go a step further and see if I could work with companies who need photographers/pilots (eg. Sierra Pacific, US Fish and Wildlife). A commercial license will be helpful in that case.

After a few minutes, we started by reviewing and signing my IACRA online, reviewing identification documents, knowledge test, pilot and medical certificates and the pilot logbook for all the necessary endorsements. Next, I was asked to show how the aircraft is ‘qualified’ for our flight today. I went through the annual for airframe, engine and propellor, reviewed the ADs that have been completed with our 50-hr inspections. We had a discussion around whether or not our planes need a 100-hr inspection considering our club is owner-operated. These planes are not considered ‘for-hire’ for flight training (because the instructors are paid directly and they are not employed by the club). DPE explained that especially for today’s checkride, since it is not flight training we don’t need a 100-hr inspection. We talked about always logging accidents and incidents with the NASA Aviation Safety Reporting System and the associated form at the back of FAR/AIM (on page 1127 in the 2018 edition).

The oral exam was a combination of scenario based and direct questions. DPE let me refer materials (I had all the handbooks and manuals on my iPad) whenever needed and occasionally even pointed out specific sections in documents to refer.

First scenario was that of a private pilot taking friends to Monterey who offer to pay for the trip. Upon landing at Monterey, FAA agent does a ramp check. We talked about this at length, including ADM, hazardous attitudes, PAVE checklist especially external pressures since friends are involved. We also discussed IMSAFE and personal minimums. It helped in the discussion that I had one already filled out. A variation on the scenario was that I had flight following but my radios died before entering Monterey class Charlie. What would I do next?

We looked at weight and balance for the aircraft. I was asked to explain how I know if it is still valid.

If placards have faded, is the aircraft still fit to fly?

We had a discussion around inoperative equipment. How do we know if fuel gauge isn’t working and would we fly with such a gauge? How about a failed attitude indicator? How should we deal with inop equipment? Then we went on to minimum equipment list, equipment list from the POH listing required equipment, A TOMATO FLAMES checklist.

Know the ADs for your aircraft, when they were complied with and in the case of recurring ADs the frequency at which to inspect.

Then we had a detailed discussion of the electrical system and fuel system. What if either the alternator or battery fails during flight. A related question was why the alternator generates 14V when the battery is only rated for 12V.

Next we reviewed the cross country plan and discussed the route, altitude choices, airspaces along the way, requirements for the airspaces, special use airspaces and their requirements, flying over water and class Bravo considerations. If the cross country was planned at night what I would do differently, do I need oxygen. Requirements for flying under class Charlie shelf and over class Delta. DPE liked the fact that I had the plan on Foreflight/iPad as well as a written cheat sheet with landmarks, headings and ETA.

We took a break before starting on the flight portion of the test. DPE said I can take all the time I needed to adequately set up for each maneuver. Flight following was at my discretion and if I chose then I should only ask for it until the maneuver area south of Sacramento.

Winds were really picking up outside so I could call for discontinuance if I was ever uncomfortable either before or during the checkride. DPE wanted to see one go-around during the course of the test. As expected, we’ll start the cross country but wouldn’t go beyond Sacramento and DPE wanted me to check the weather at all the local airports and point out the ones I wouldn’t be comfortable landing for a diversion. Mather and Auburn were at or above my 10 kts crosswind component limit and the rest were manageable.

We started with a soft field takeoff and I called up Norcal for flight following (just because I could) and started tracking heading for first checkpoint on the cross country plan to intercept a radial from SAC VOR. Then I turned towards the VOR for my second checkpoint when the DPE said passengers in the back seat were feeling airsick. So I changed destination to KSAC. We landed then taxied back for a soft field takeoff departing right 45 towards Folsom lake for maneuvers. First, I realized my window was open when I took off and tried to close it on upwind but the winds were blowing me around. Steve’s advice to “fly the plane” rang in my ears and I left the windows alone to stay with the climb out at 75-80 kts and stabilizing before trying again to close the window. Second, in the distraction I almost busted into Sacramento’s class Charlie. En route, I donned the hood for instrument work and two unusual attitudes.

Next we started with slow flight in the landing configuration. DPE asked me to start a shallow turn at 60 kts when I was still getting configured towards my usual flying slow flight at 50 kts. So I was a little bit caught off guard. We discussed this later in the debrief after checkride. Then I did power OFF stall in the landing configuration, power ON stall in the takeoff configuration, steep turns to the left then right. From there we proceeded to Lincoln for some landings.

First was a soft field landing, touch and go back for short field landing. Then we did a forward slip to landing. My approach was too high so went around and tried it again. KLHM was too busy so I was #3 and the aircraft in front of me was too slow so I did a left 360 and rejoined final for a full stop and the conclusion of checkride. I was allowed to use a combination of Garmin 430, VOR, Foreflight on iPad and scribbled notes for navigation. We taxied back to the hangars and the DPE congratulated me that I had passed the checkride as we were getting out of the aircraft.

Some feedback that I received after the checkride:

  1. My radio work was excellent both on towered and non-towered airports
  2. Recovery from unusual attitudes under the hood were very good and prompt
  3. DPE never felt that safety was a concern (even when I realized my window was open).
  4. Use one full arc nose-up trim on steep turns and a little bit of power as needed then the plane should fly the steep turn without elevator back pressure.
  5. Stay on the centerline with lots of right rudder especially on soft field takeoff when the nose wheel is off the runway. So there is even less directional control with sole reliance on the rudder which itself is inherently not very effective on the high angle of attack configuration.
  6. Don’t start working on instrument approaches until perfecting instrument scan and holding altitude/heading accurately.

We started at 9:10am and I was done by 2:30pm. Felt at ease throughout and never felt rushed. I had sufficient time to review my maneuver checklist before each one. I gave it my best shot and I’m sure I used the full latitude of ACS standards i.e., my performance  was by no means perfect. After all, what I’ve just earned is a Private Pilot’s License to learn.

Checkride Route

Headwinds & Tailwinds

Aviation, , , , , , , , , , , ,

Srinath was on the left seat today and he started with a soft field takeoff and left downwind departure. At Tracy, winds were from 310@7kts where he did a soft field landing. The sink hole just past the threshold of rwy 30 is to be respected. There is usually an appreciable downdraft as the plane passes over the sink hole so anticipate it and increase the power a little bit. As you clear the sink hole and approach the threshold, ease back on the power and the word I keep hearing Steve repeat is “patience…patience” to wait for the runway to approach the aircraft. In other words, descend slowly for a gentle touchdown.

Next we headed for New Jerusalem by making a left 270 over the runway and passing over mid-field. The runways at both Tracy and New J were slick and wet from rains and that calls for extra caution while using brakes. We landed twice at New J, the second landing took up quite a bit of runway so we turned around. And since the winds were low (estimated 8-10kts), Steve asked Srinath to take off on rwy 12 so he can see how the tailwind leads to a significantly longer ground roll before takeoff.

Next, we headed to Byron against stiff headwinds from 310@15kts. We heard a Piper (58K from our club) on the radio practicing patterns and a glider coming in to land at the airport as well. This was a great practice session anticipating where the traffic would be as we executed a straight-in approached for rwy 30. Steve had a little fun on the radio with Mike (CFI on 58K) when he recognized the voice. Srinath and I both had questions for Steve as we were trying to figure out the spatial locations where the three aircrafts would be as we approached further. Since 58K was on final and we were coming up on 5 miles, we anticipated that we’ll land before 58K comes around for its next pattern. What we didn’t factor into the equation was the fact that we were going against a stiff headwind in a low power setting for landing and 58K would be gunning its engines for takeoff, followed by a stiff tailwind towards us on the downwind leg. Our ground speed was only 40kts and then 35kts as we got lower and closer.

Mike couldn’t spot us so we announced that we were a quarter mile shy of the second canal. What Steve meant was the second canal seen from our approach the runway i.e. the closer one to the airport. Mike understood that we were on the second canal from the airport i.e. the farther one from the airport. So he announced that he was turning base in front of us. We were all taken by surprise when he announced that and saw 58K turn directly towards us. Steve immediately took evasive action by banking left and as soon as we turned, Mike was able to see us and apologized for the mixup.  We let Mike land and in the meantime we did a left 360 and lined up to land on rwy 30.

Srinath capped off the training with a few touch-and-go’s at Livermore performing short approach landings.

 

Close call and then a Solo

Aviation, , , , , , , , , , , , , , ,

Today wind was 240@9kts at Livermore.We departed right downwind towards Byron where the wind was 210@6kts and clear skies.Apparently I was still on Livermore tower frequency (00:21:12 in the video) when I announced on the radio that we were inbound for Rwy 23. We did a short field landing (02:09:00) at Byron followed by a maximum performance takeoff (02:35:00). Next we proceeded to Tracy (winds 260@10) and did a soft field landing on Rwy 26 (05:32:22) followed by a regular takeoff.

We next headed to New Jerusalem which is only 7 miles away and aimed for Rwy 30. Winds were from 260 (no ATIS or AWOS in New J so we go by the Tracy weather) so it was a crosswind (06:39:00) for Rwy 30. We only employed 20 degrees of flaps and that caused us not to sufficiently slow down and remain low for landing. As we approached the runway, the airspeed got very low to 50kts and Steve pushed the throttle for a go-around at the last minute (07:32:19) as the stall horn started going off. I was apparently not watching the airspeed at all, being more intent on getting the plane low enough (through a slip) for the landing (10:02:04). That was a close call. On reflection, the thought did cross my mind that perhaps I should go around given I was so high. I should have gone around as soon as the thought crossed my mind. We did two more successful attempts before heading back to Livermore.

Over the Altamont pass just before I was going to call Livermore tower, I saw an aircraft coming straight at us. I simply pointed it out to Steve (11:32:24) who immediately banked us sharply to the left and we noticed the other aircraft pass us (slightly below). It seemed like it would have been a head-on approach and that got me quite shaken up. I should have gotten us out of trouble the moment I saw the aircraft. In reviewing the radio communications just prior, there were two aircrafts that had departed Livermore. 53MM was ahead of 7E(something) and 7E(something) confirmed to the tower that the Cherokee traffic ahead of it was in sight (11:02:11). Tower then approved 7E(something) for a frequency chance and then radio’ed 53MM that traffic was behind to its left at 2500′ and had 53MM in sight. 53MM’s frequency change was next approved. So both those aircraft were heading towards us and no longer talking to Livermore Tower. We were tuned into the Livermore Tower frequency but the three of us were neither talking to each other, nor talking to the Tower. We were in a see and avoid territory and while I saw what was most likely 53MM, I was slow to avoid. Maybe I had a premonition about this event because I asked Steve a question at the start of our flight (00:02:18 in the video) about how we deal with oncoming traffic that uses the same general path.

Back at Livermore, Steve sent me off to fly my solo in a pattern around a towered airport. I did 3 touch and go’s and on all three attempts I was #2 behind another aircraft. I had to extend my downwind leg, watch for the aircraft ahead of me before turning base.

Pattern work is never routine

Aviation, , , , , , ,

Steve asks, “What would you do if the door opens in flight”? First off, the wind will push the door back towards the frame. It will be a distraction but the right action is to focus on flying the plane and land it as soon as possible to secure the door once again.

We started with soft field takeoff. On the turn to crosswind, we noticed that the clouds were very low. The ceiling was barely enough for pattern work so we stayed right around 1000′ MSL for the entire pattern. But the second time around the pattern it was already a little bit better. We then focused on soft field landing, precision landing and a high performance takeoff to clear a 50′ obstacle.

Steve offered a glimpse into what he likes about flying – that it is different each time making it interesting and challenging. The winds change in direction and intensity, sometimes with no notice. The winds referenced in ATIS wouldn’t match reality and that injects an element of surprise. Then there are birds, especially around Livermore and especially when a weather front was approaching. They seem to materialize out of nowhere and throw in an element of surprise at exactly those instants when one wishes to be 100% focused on lining up in the pattern. Then there is traffic, which suddenly seems to become hectic and quietens down as quickly as it surged. Controllers would suddenly change sequence, or extend a pattern, or re-route to a different runway with an opposite pattern, or speed up a turn throwing a wrench on one’s plans for the landing.

And today we encountered a new surprise – unexpected clouds at low altitude. Patterns around the airport are not routine.

Engine out on takeoff

Aviation, , , , , , , , , , , , ,

We departed 25R on a left downwind departure towards New Jerusalem and just as we took off, Steve pulled the power without warning. Srinath did the right thing by “flying the plane” and landing it back on the runway. Steve then pushed the throttle in and we took off. This was a lesson in emergency procedures since the engine could quit just at takeoff. In that case, the best place to land is straight ahead. Never try to turn back to the runway because that effectively requires a 270 degree turn in one direction and then a 90 degree turn in the opposite direction to line back up with the runway. At low altitudes with engine out this turn is almost always impossible to make. In the heart-thumping moments, getting into a stall spin accident becomes likely and with grave consequences. No matter what is ahead, the best bet is to land it almost as straight ahead as possible with minor corrections.

Once at New Jerusalem, Srinath practiced soft field landings and takeoffs as well as a maximum performance takeoff. We next headed to Byron to fill up gas because the new gas station at Livermore isn’t fully functional yet. On approach to Byron, Srinath did a straight-in landing and this time a precision landing on the numbers.

After re-fueling, we taxied back to runway 30 and heard a heads-up that skydivers (jumpers) were heading down from 10,000’. It was incredible that they came down in no time at all, well before we completed the run-up checks and were at the hold short line for runway 30.

We waited for a tricycle geared Maule to land. Steve referred to this as a “quintessential bush plane”. Normally they are tail draggers so it was interesting to see one in a tricycle gear. There was a lesson in not hurrying to the threshold for takeoff because the Maule hadn’t yet turned off Rwy 30 on a taxiway. Just as we got ready to  takeoff, more jumpers were getting ready to unload at 13,000’.

Just as we were over Brushy Peak heading in to Livermore, I noticed gas gushing out of the fuel vents like crazy. Never seen so much fuel come out in such volume continuously. Steve asked if the fuel caps were on, which they were. In measuring the fuel after the flight, we estimated about a gallon was lost! Not sure what caused this…

New Year Flight

Aviation, , , , , , , , , , , , , , , , , ,

Today the winds were calm and clouds were 4900′ scattered. As we taxied out, we noticed that the construction of Three Rivers FBO is making good progress and they are getting ready to open by Super Bowl. The new fuel station has been opened and the old one removed. Miraculously, the intercom in the back seat of N906MD has been fixed! We no longer need an intercom extender and people in the front seats can hear the person in the back.

We headed to Byron and made steep turns in the vicinity of the airport. Upon rolling out of the steep turn, use opposite rudder to stop the turn. Then Srinath practiced slow flight followed by three kinds of stall. First, power-on (departure) stall. Upon reaching stall, just relax the back pressure on the yoke. Because it is a power-on stall, the engine is already running pretty hard so relaxing the yoke should cause it to recover quickly. If you shove the power in, more altitude will be lost before recovery. It is only in a power-off stall that once recovery is achieved with relaxing the yoke that the power should be shoved in.

Power-off stall was next, followed by an approach to landing stall. Start with a pre-landing checklist, then come back on the power to extend full flaps while within the white arc. Achieve a descent as if we are coming in for landing. Then pull back to stall. Recovery is the same as a power-off stall – relax the yoke to drop the nose and build up airspeed then shove full throttle. So we went through all varieties of stalls today.

Steve pulled back the throttle to simulate an engine out situation. The ABC checklist comes in handy here – Airspeed, Best place to land, Checklist to attempt restarting the engine. It is important to achieve and maintain the airspeed for best glide. On the 172 that is 65kts. Then you determine the direction of wind and scout for the best place to land. Preferably you land into the wind. In our case we found a restricted runway which of course would have been fair game in the event of an emergency. Keep the runway in view all the time as you weave around and descend. If there was no runway, look for a hard field or green field but certainly not one that is wet or just recently plowed. Land along the furrows if there are any.

We proceeded to a long pipe in the vicinity, descended to 800′ AGL and made S-turns by entering downwind. The first maneuver was intended to watch for the wind and the right turn ended up being too shallow because the wind pushed us into the turn. On the next attempt Srinath proceed a little further ahead before attempting the turn. He could also have tried a shallower right turn so the wind pushing us back would have made it a fine semicircular turn.

Finally Steve asked Srinath to use the GPS to take us directly to Byron. He landed by making a right base turn and after touchdown Srinath tried maneuvering the plane to get on the centerline which Steve reminded him never to do so for the risk of getting into a ground loop. Just staying parallel to the runway is sufficient. Srinath took off with a soft-field technique. Once the nose comes up off the “dirt”, shove in full power to maintain the nose slightly off the runway until the plane lifts off. Then push the yoke forward to stay in ground effect to build up airspeed before climbing out.

Finally, maximum performance takeoff. Stand on the brakes and shove the throttle fully in. Watch the RPM come up to 2200 and then release the brakes. Plane will race forward rapidly. Maintain control and at 60kts, pull back on the yoke to climb at Vx until a “50-foot obstacle” has been cleared. Then relax the back pressure to build up airspeed and climb at Vy. After a pattern, Srinath did a precision landing on the numbers. One more maximum performance takeoff followed by a 270 turn to overfly midfield before heading back to Livermore.

A bit of drama on the way back to Livermore. Our radio didn’t connect well and we barely heard the tower transmission after we reported our position over Brushy Peak. Tower asked another aircraft in the vicinity to check if we could hear them. In the meantime, because of this, Steve took us on a 360 right  turn to maintain position over Brushy Peak while we re-established connection. A mooney was taking off from Livermore and heading in our general direction, which is probably why Steve did the turn. We were soon cleared in to land on runway 7L.

Another second solo

Aviation, , , , , , , , , , , ,

Perfect weather today with calm winds. We headed to Byron first. An airport vehicle was performing runway field inspection at Byron on the 23/05 runway, but only after radioing to confirm nobody will be headed that way. We announced our intention to land on 30.

We did a regular landing and takeoff at Byron followed by a soft field landing and takeoff at Tracy and a no flap landing at New J. On the last one, I significantly overshot the runway (because we were faster than usual) before correcting for the landing. On the next landing, used a slip to slow down and drop altitude. Balked landing next – “there is a cow on the runway”. Final landing was a bit rough, after which Steve asked me to fly a solo completing three patterns around the airport.

There was a pickup truck beside the runway at New J which we had spotted on the first approach. It was apparently owned by a CFI who happened to be there that day to fly a paraglider (which was tucked into his trunk). After the solo, Steve told me that that CFI complimented me on all three landings and takeoffs.

 

Soft field takeoffs and landings

Aviation, , , , , ,

Ceiling at Livermore was 1500’ broken so our pattern today was lower than usual. A storm was about to roll in. When we see seagulls in the airport vicinity, Steve forecasts that a storm is impending. There were lots of birds today and once we had to bank sharply to the left on the upwind after takeoff to avoid some of them.

Today we focused on soft field takeoffs and landings. We did the landings with only 20 degrees of flaps and with a little bit of power (65kts instead of the usual 60kts) to hold the plane off the rough runway. If this was a real soft field, then the extra speed will help touch down gently and also in not letting the wheels dig into the muck.

Winds picked up after a few touch and go’s, turning into 240@10. On one of the patterns, a twin Diamond was departing ahead of us so tower asked us to extend downwind and called our base turn.
