May 20 – Airman Knowledge Test

Aviation,

Back in early 2014 as Srinath and I were seriously considering flight training, I spoke to a couple of co-workers who were pilots for recommendations. Two of the best recommendations were – attend a Private Pilot ground school and find an instructor who will let the two of us learn in tandem. Somebody then mentioned an offer on Groupon for a very affordably priced 14-week ground school training plus introductory flight, both at at Trade Winds Aviation. Srinath and I had already taken our first flight in a Bay Tour but still this was a good deal on Groupon.

The ground school was rather convenient on weekday evenings with the location of Reid-Hillview airport being on my drive back home from work. A regimented classroom program got me back into the rhythm of learning brand new material and the instructor Don MacLennan was both entertaining and erudite. There was also the excitement of heading to the airport every week and watching the general aviation activity. There were multiple classes and instructors so even if we missed a class, we could attend a make-up class on another day with another instructor. At the end of the program we took a test and those who passed with over 70% got an endorsement to appear for the Airman Knowledge Test. This was in May of 2014 and I decided that time not to take the test immediately and instead to take it when I was far enough along with flight training. My theory was that that would give me a chance to soak in the material.

I finally took the test today and passed it with 88%. The test was more difficult than the practice tests I had taken recently.

The ground school used ASA’s Private Pilot Test Prep 2016 which was both concise and comprehensive. Concise in the materials introducing each section and comprehensive in the number of questions that follow in each section. The book also came with a code that was good for 5 practice tests that you can take online. The format of the tests was very similar to the real deal. I found many of the questions in the practice tests came from the review material in the book so it wouldn’t be terribly helpful if you just recently studied the material from that book.

I also used the Sporty’s Private Pilot Learn to Fly Test Prep Course. It is pricey at $199 but it has the entire video set on flight training, plus 2 practice tests for the Knowledge Test and study material. I took one of the tests and it was fairly challenging. Again the format was very similar to the real deal.

My scores in the two practice tests were 90% and 94%. I met Steve yesterday morning and showed him the results. He decided to quiz me for a while and then endorsed my logbook. This morning I showed up at California Airways in Hayward, CA where I had made a reservation to take the test. The proctor (big boss) at the test center showed up 20 minutes late citing traffic on the way. Funny because I drove past Castro Valley where he lived. While I was waiting, a CFI was working with his student. He was pushy and decided to sell me his services urging me to switch to his school and that he will take care of my training when I asked him how much he charged.

High Air Work

Planned to fly at 8am but ceiling was quite low – Marginal VFR. Pushed it out to 9am but weather was no better according to METAR. Steve said it was good enough to fly on the other side of the ridge. The METAR said ceiling was 1500′ but we saw other planes fly the pattern altitude around the Livermore airport and there was plenty of clearance. The METAR only looks at the sky above the tower where they typically take the readings. After takeoff, we stayed just about 2000′ flying to the right of brushy peak but not that much higher than its summit. On the other side in the valley, ceiling was greater.

Lots of workout today. We did slow flight, approach to landing stall, power off stall in the clean configuration, power on stall, turns around a point, 8’s around pylons and two touch-and-go at Tracy before heading back home.

After refueling, I didn’t go through the checklist and couldn’t figure out why the engine would just not start. Turned out I had not enriched the mixture. Steve shouted it out simply based on how the engine sounded from the outside. 🙂

 

Local patterns

Aviation, , , , , , ,

Srinath and I both flew patterns today at Livermore, one after the other. N906MD continues to have starting trouble.

The traffic controller lost situational awareness on more than one occasion – when I was taxiing off 25L back for takeoff and again when there were a few planes in the air. On the latter situation, he sent one of the planes on downwind and never called his base turn until the pilot radioed and said he had gone almost to Brushy Peak. He then asked for my position and turned me base in front of the other plane.

When Srinath took off, he was cleared for 25R but for a left pattern on 25L. The radio communication snippet will be helpful because it was confusing to me the first time I heard it.

During my pattern, I asked to be switched to 25R when I was cleared for left pattern on 25L. The controller accommodated me and that too is a helpful radio communication snippet.

Solo in the Tri-Valley

Starting up 737GM was a bit of a bear but chose to fly it this morning because 906MD’s carburetor was being re-worked due to starting problems. Tower cleared me for takeoff on 7L. Winds 130@5kts but quite variable.

Flight to Byron was quite straightforward and it was a good smooth landing. On the flight from Byron to Tracy, I had still been tuned to the Byron radio and I was wondering why Tracy traffic wasn’t announcing on the radio. I was still hearing Byron traffic. While in the pattern at Tracy, I saw an aircraft taking off and one waiting to take off and I had not heard either of them speak on the radio. It was only when I was nearing base turn in the Tracy pattern that I realized my mistake. Landing at Tracy was also good. I next proceeded to New Jerusalem where it was a bouncy touch and go. The flight back to Livermore was uneventful.

Patterns in 737GM

Aviation, , , , , ,

The weather continues to be unusual. It is the middle of April and it rained overnight into early morning. Winds are expected to start howling in the afternoon. I woke up at 6am to notice calm conditions so I was eager to fly this morning. 906MD’s starter had finally gotten so bad that it was nearly impossible to start it up. Also, COM2 hasn’t been working for a while so the plane has been grounded for maintenance. Fortunately 737GM was available but since it has been almost two weeks since I last flew, I texted Steve to see if he will join me for a couple of patterns around the airport before I fly solo to Byron, Tracy and back. He was available and we decided to meet at 8:30am. On the way to the airport, I checked AWOS to note that there was a 7kts wind from 240 at Livermore, 9kts from 220 at Byron and 11 its at Tracy from 260.

737GM wasn’t easy to start either. It took a number of primes and then a number of throttle primes. We pushed the throttle fully in and kept pumping it while the engine continued to sputter. It gradually picked up RPM and was finally able to idle around 700rpm.

We did 4 patterns around Livermore before Steve declared that he had had enough and decided to get dropped off at the northwest tiedowns while I kept the engine running and continued on a solo. Two things I noticed are (1) that the throttle lever is significantly shorter compared to the one on 906MD and (2) that the throttle lever slips out very easily when the friction lock is not engaged. A couple of times I took my hand off the throttle to adjust trim and the engine rpm dropped as indicated by a change in the hum. Steve and I both lunged for the throttle at the same time to push it back in.

I got a clearance for right downwind on 25R and as I flew towards Brushy Peak, it got significantly bumpier. Clearly the winds were stronger the higher I flew. I chickened out and asked Tower to bring me back in for 25R. I appreciated that the Tower thought there might be a problem and asked if I need any assistance. It continued to be windy and bumpy but not terribly problematic so I did 4 touch and go’s back at Livermore before calling it quits.

Patterns after another hiatus

It has been a while so Srinath flew dual today with Steve. School kept getting in his way. The day started off with calm winds and clear sky. It was a day of doing patterns around the airport and Srinath’s rustiness showed.

The variety today involved following a Champ which was significantly slower than us, and a jet that was faster and ahead of us. On one pattern, the Champ was so slow that Steve requested a right 360 (while downwind for 25L) to increase separation. The wind then shifted significantly and that indicated runway switch was impending. Sure enough, tower asked if we can take a 9kts tailwind or if we wanted to wait to land until the runways were switched. Steve decided to take the tailwind to show Srinath how that feels for ground roll. Then after turning crosswind on the next pattern, the tower changed direction and gave him instructions to turn right for 7R.

On that last approach a jet was turning base for 7L while Srinath turned right base for 7R and they both touched town almost in parallel.

First solo to another airport

Aviation, , , , , , ,

Today was my first solo flight taking off and flying outside of Livermore. I went to Byron, then Tracy and back.

As I requested frequency change approaching brushy peak, tower alerted me to traffic in the opposite direction which I never was able to locate. After touching down at Byron, I taxied off to reset for the leg to Tracy. On the way back to Livermore as I approached Altamont, tower first alerted me to a traffic 1mi south for straight in to 25R and asked me to report for a 2mi  right base implying I had to turn right towards brushy peak. Then tower changed the instructions to make a right 360 and then straight in for 25R.

First flight on 737GM

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

Srinath and I flew dual with Steve today on 737GM. It is a Cessna 172 modified with STOL capability and 40 degrees of flaps. The goal for today is to get us a feel for the aircraft especially with full flaps so we can fly that whenever 906MD was unavailable.

As we took off on a left downwind departure, the guy who was just ahead of us encountered a bird strike and declared an emergency (“Mayday”) and wanted to return for a precautionary landing. Srinath overflew Tracy at which point he practiced slow flight with full flaps and a couple of stalls in the landing configuration. He then proceeded to New Jerusalem to practice landings with full 40 degrees of flaps. The last two landings were short approaches. It was incredible how slowly and with a tight turn we could approach for short landing.

We taxied back to Rwy 30 at New J, watched a plane do a couple of touch and go before Srinath and I switched on the left seat. I had a chance to the same air work that Srinath did previously, then we headed back to Livermore.

As we radioed the tower over altamont, we were asked to follow a Mooney and then tower asked us to join downwind midfield for a landing.We later figured out this was because there was somebody behind us on an ILS approach. This was very unusual and it took me a while to regain my situational awareness. Essentially we turned north after crossing the altamont, west and then south towards midfield. Then turned east for right downwind pattern landing.

 

Radio trouble

Aviation, , , , , , , ,

Srinath flew his first full solo at Livermore today running patterns to practice takeoffs and landings. We used two GoPro cameras today for the very first time, one mounted in the usual spot at the back of the aircraft looking forwards and the other one on the copilot’s window facing the PIC. They both had audio inputs from the radio.

It was a busy day and Srinath was asked to follow other aircraft, extend the crosswind and once even asked to come to a full stop to sequence other departing aircrafts. The solo was uneventful except for a brief period (9:07) on the downwind leg.

I had driven to the hangar to see Srinath fly the pattern. The club’s other plane 733BE had just gone through a 50-hour maintenance and our test pilot conferred with Steve on the maintenance items before he took it out for two touch and go patterns. He was in the pattern behind Srinath. On the ground, Steve and I were watching Srinath.

Tower communicated with Srinath that he was #2 behind a Pitt. No response. Tower tried twice more and still no response from Srinath. I was tuned into LiveATC listening to the ATC and mentioned to Steve that I was worried Srinath didn’t respond to the calls. Within a minute, I heard Srinath check his mic and soon he told tower that he might have a radio problem.

He called it quits after that pattern to my relief. Was there a problem with the headset? We squawk’ed that there might be a problem with the radio. Our club’s maintenance team looked into it and didn’t find any problems. The audio feed into GoPro caught the radio communications just fine. We have not encountered any issues with the headset since. Did Srinath simply get distracted for a while and missed the calls?

Traffic…Go Around

Aviation, , , , ,

Srinath flew solo around the Livermore traffic pattern. Just as he turned downwind on one of the patterns, tower cleared him as #2 for 25L and Srinath confirmed he was scanning for traffic (3BE) that was on a 3 mile final. But it was clear he never saw the traffic. He was on base when he asked if he was #1 for 25L and tower reminded him he was #2 behind the traffic which was now on a short final. It turned out that Srinath turned too soon so there wasn’t enough separation with the traffic ahead that had just landed and hadn’t yet turned off the runway. Tower asked Srinath to go around, after which he did a couple more patterns before calling it a day.
