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.
A couple of days ago on June 30 we did a bunch of landings at Livermore. All them were decent or better, with one of them very good that Steve didn’t feel compelled to give me any instructions.
We started today with steep turns, power-off stall and then a simulated engine-out landing at Byron. On this approach we had quite a bit of altitude to lose. We tried a slip but that didn’t bring us down much because of headwinds. Then we tried S-turns to lose altitude. After 4 landings, we decided to head to New Jerusalem. It was a warm and cloudy day. The density altitude at Tracy was reported as 1600′. Reflecting on the landings at Byron I suggested that maybe extending downwind would have made it easier to land. Steve was emphatic (7:34 into the video) that that was not only necessary but it will provide more opportunities to botch a landing.
On the first landing at New Jerusalem, I came down hard and bounced up quite a bit. I didn’t react quickly so Steve shoved in the throttle (8:24) and did a go around. Rightfully he gave me an earful. The second landing was ok – flared up a little too much but was able to bring the plane down just fine. After two more good landings, Steve endorsed me to fly solo.
It was unnerving to hear Steve ask me to fly solo but once I got into the cockpit and started the preparations, all such nervousness dissipated. During the flight there was so much to mentally manage that there was no time to feel nervous. I felt ready to handle it with all the training I’d received. The first landing was alright but on the second landing I bounced. And bounced high. Thankfully Steve’s words must have stuck in the back of my mind because I immediately pushed the throttle forward and did a go-around. The nose wanted to point way high up with full flaps deployed for the landing and I remember pushing forward hard on the yoke to fly nearly level and build up airspeed before climbing and slowly retracting the flaps a notch at a time. Perhaps I came in too fast and too flat causing the serious bounce. Since I did a go-around, I decided to do two more landings for a total of 4. They were not great but I managed to make them stick. The rest of the flight back home was uneventful.
This unfortunately ended up being my last flight on N25ES. In the following week another member of my flying club flew the plane and while practicing touch-and-go at Livermore bounced hard on a landing. The plane porpoised but the pilot did not attempt a go-around expecting to salvage the landing. The nose gear touched down first and the prop stuck the tarmac. The pilot was fortunately alright. He was a low-time pilot (having recently earned his private pilot’s license on the Cessna 152 and only a couple of hours of experience on the 172) and didn’t realize the seriousness of what had just happened. He did a few more touch-and-go before calling it quits. Later inspection revealed that the tip of one prop had broken off and the firewall had buckled. The plane ended up as a total loss and an insurance claim. The club has started a search for a replacement 172.

We started off with Steve handing me stylish eyewear i.e. flying under the hood. After maintaining a heading and then tracking a VOR, I practiced two stalls in the clean configuration and recovery. Using only instruments under the hood. Then I practiced an approach to landing stall. First by initiating a descent, slowing down to 1500rpm and deploying flaps. The idea is to simulate a landing approach. Then pulling up the plane in this configuration and initiating a stall the plane. Recovery is similar to a stall in the call configuration with the exception that we have flaps deployed. So slowly retract flaps step by step when a climb has been achieved.
Next, I practiced slow flight with shallow turns. And then Steve pulled the power out simulating an engine out situation. We scouted a field and when we got pretty low, Steve pushed the throttle and we headed over Byron.
The winds were really strong at 20kts but fortunately it was a headwind on Rwy 23. Still the ride was really bumpy, perhaps the bumpiest of all our flights thus far. We practiced a couple of touch-and-go and then headed to Livermore for a couple more.
On the second touch and go at Livermore, we ballooned after touchdown due to the wind so Steve immediately did a go-around. I wasn’t quick enough to react and this was a good learning experience. After one more landing, we called it quits for the day.
The annual Wings of Freedom Tour is going on this weekend at the Livermore airport. As we pulled up beside our hangar, a B-17 Flying Fortress “Nine 0 Nine” was going through its run up check prior to takeoff. The Collings Foundation offers tours on its fleet of WWII aircraft as they tour around the country. The sound of its Wright-Cyclone engines thumped through the air and echoed off the nearby hills. Our hangar is one of the closest to the run up area and a group had gathered for best views and to photograph the spectacle.
We took off on 25R and headed right downwind. As we were climbing, Steve spotted a B-25 on our right heading towards the airport to perform an overhead break. Very soon Steve handed me stylish eyewear, his term for the instrument hood. After maintaining different headings, Steve asked me to stall the plane. Under the hood! Without realizing, I ended up in a falling leaf stall so I did it again, this time consciously and without the hood. The plane was clearly unhappy as it bounced around in a stall condition.
Today we tried boxing the sky for the very first time. Using full rudder to move the nose to the left and right while at the same time using the ailerons to keep the wings level. After a few boxes, we headed to the New Jerusalem airport. It was pretty close by and we had quite a bit of altitude to lose so we did a side slip with nose slightly nose down and fully cross controlled. We did 5 touch-and-go at New J before heading back to Livermore.
As we got close to Tracy to turn west towards Livermore, the B-17 passed ahead of us and we followed it all the way to Livermore. He was lower so we didn’t have any threat from wake turbulence. We did watch where he landed so we could touchdown farther to avoid the wake turbulence on the runway. The bombers were done for the day and we taxied past them on our way to fuel.
had never seen these WWII aircraft in airworthy condition, let alone flying or taxiing amidst these heroes. Today was a memorable day! Here is the full flight track for the day.
This morning the winds were from 050 at 9kts. So runway 7L and 7R were in operation. This meant a long taxi from our hangar and a good time to lean the mixture. Carburetors are calibrated to properly mix fuel with air at sea level. During normal engine operation, a proper air-fuel mixture is fully burned in the engine for optimal performance. When the engine runs at a low RPM (for instance while taxiing), the rich air-fuel mixture isn’t fully burned due to a cooler engine. This causes carbon buildup in the spark plugs and the fouling can result in lower engine performance. The carbon buildup can also occur if the mixture is too rich e.g. at higher altitudes where the air density is lower but unadjusted fuel density remains higher. For better engine performance, less likelihood of spark plugs fouling up and to warm the engine sooner, leaning the mixture is recommended when a long taxi is anticipated.
We start off by performing power-off stall recovery in the clean configuration. I was very slow in powering up the engine to recover from stalls and as a result dropped over 500′ on the first couple of attempts attempt. After many tries, ended up with between 50′-75′ of altitude loss.
Then Steve demonstrated a power-on stall with 2200 rpm on the engine i.e. not fully powered up. Power-on stalls typically occur during takeoff or a go-around. Listen for the stall horn and drop the nose. Steve demonstrated a tendency to spin to the left if the stall is not recognized quickly. If that happens, the first thing to do is to pull back the power and relax the back pressure to increase air speed over the wings to produce lift. Then power up and pull back.
Next was engine out simulation. First trim for a glide speed of 65kts. Then run through a checklist
Was the fuel selector accidentally kicked around or is the selector still on both?
Is the mixture rich?
Is the carburetor heat off?
Check the throttle
Check mag switch positions and whether that revives the engine
Check the primer if it is IN i.e. off.
Once the usual suspects have been eliminated, observe the wind and look for a place to land into the wind. Brown fields better than green (wet). Smooth fields better than plowed fields. If plowed, along the furrows better than across. No railroad tracks. Since we identified a place to land and it was pretty much beneath us, we had to lose altitude quickly. One could either perform 360 turns to lose altitude. Or, in this case Steve demonstrated a forward slip.
Time for a ground reference maneuver – turns around a point. It is important to enter the maneuver downwind and maintain about 800′ AGL. On the first orbit observe the effects of the wind and remember mental landmarks where the turns should occur. Subsequent turns are expected to be more accurate. At one point, Steve suddenly took over controls and performed an evasive action by banking the plane to the right. This was upon spotting another plane in the vicinity. Then back to the ground reference maneuver this time turns to the right.
Finally, time for some touch-and-go’s at Byron. Steve talking on the radio for each leg of the approach to Byron is quite informative. The first landing was pretty hard, second was good and the third was below average.
On the way back to Livermore, we had a close call with a Skycatcher coming towards us. Tower told us that the Skycatcher was 3 miles out at 2000′ and we were at 3100′. A couple of minutes later, the tower informed the Skycatcher (which was now at 2400′) that an inbound Cessna was 1.5 miles in front and suggested that he turn right. As I was commenting to Steve that 3100′ was about our altitude, he gestured me to turn right. While I was trying to process the information, the tower asked us to turn right because of the Skycatcher and Steve jumped on it right away to avoid the oncoming aircraft.
