Lesson 7

Back again ! No lessons the last two weekends because of the weather, rain, rain and rain.
Beautiful today 🙂
After warming up, we lined up for Rangiora Runway 25, facing West. I did a complete take-off, with a little help from Dave with the indication when to full the stick to lift up the nose. And when it came up we had lift-off almost instantly and quickly gained height, making a right turn towards our practice area at Loburn, flying at level flight at 2000ft first and later at 2500ft towards Mt Tomas.
While his was happening, I did a few left and right turns, trying to find a plane we heard on the radio, that we thought would be nearby, but couldn’t spot….

You notice that after not flying for two weekends you need to get into it again, so really need to try to keep up with my lessons, not that anything went wrong, but you just feel that.

Next thing was doing stalls. Here Dave is still doing them, to show me what they are like and how to get out of them.
So engine idle, pulling the stick more and more to keep level flight, and the at around or just below 40 mph it it stalls. We did about 3 I think with no flaps. We had 2 where both wings stall, that’s a nice one and all you do is push the stick 2″ or so forward to assist the “dive” gaining speed, and if I remember well, with that stick position and applied engine power, you climb again to your original altitude, level off and its done.
With a side slip were one wing stalls first, you apply full rudder in opposite direction to get the wind flowing again over that wing, and then the rest is the same….
After that we applied flaps, full flaps I think, and here the plane stalled at a much lower speed, something like 25 mph. The stall was much gentler and not so abrupt.

On our way back to Rangiora, Dave showed me zig zagging. Basically starting a turn, by banking and rudder, and then a few seconds later changing bank to opposite direction, and correction the slip with opposite rudder direction. A good way of practising the rudder and aileron coordination. Pretty sure we will be doing this more.

By now we arrived at the Rangiora circuit again, were we joined by flying at 1500ft above ground level ,then making a right turn, flying over the threshold (end of the runway) down to 1000ft, followed by a down wind leg, and then the last turn with full flaps to land an the same runway 25 again. Not sure anymore, but I think I did most of the landing “work”, basically flying down to a few feet, maybe 10 ft, pulling the stick to go level flight and while still slowing down, you just come down and land  🙂
Turning left as you do to clear the runway, making a 360 turn to check traffic, then across the runway to the other side back to the hangar.

All in all a good flight again !!!!!!

Fuel pump

Installed a little fuel pump today. Reading the carburetor specs on my engine, I found that I needed at least 24″ of fuel pressure, and with my tank position I didn’t have that. This little electronic pump creates a pressure of about 3 PSI, not a lot but that’s what the specs required. After I installed it I had it running for a few minutes without running engine and no flooding of the carb, so the fuel control needle valve inside the carb must be working nicely. As soon as the ring exhaust is back, I can try it out.

Oh yes, when pump is not running, the fuel still flows, so that’s good.

In the past when the engine was running, it looked OK with the fuel pressure, but once or twice in the early stages, the engine stopped on us with not a lot of fuel left in the tank, so maybe that’s what it was.

Nicely going down, all the way from the tank to the carburetor.

Lesson 6

Another Saturday, another flying lesson  🙂
Always looking into the sky on a Saturday morning, is it going to be calm enough (for me)  🙂 A bit of a Southerly, will be OK I think..
Arriving at the airport there was a bit Nor-Wester, but hardly anything, so not to bad.

The first long missing bit is where we flew slow, then another short bit missing were we did the stalls, and just before the landing another one. This is because the automatic logging feature on my phone, was set at a speed that was a bit to high….  Sorry

The lesson started with 3 high speed taxi’s using the whole runway, the long one, to get a bit of a feeling of how much to pull the stick, trying to keep the front wheel just off the ground. So adjusting all the time. A bit to much and you take off….
The third high speed taxi, ended up in the takeoff to start the flying lesson.
More turns, left and right, keeping speed and altitude under control. During the first few minutes we had some turbulence, so decided to move to an other area, while doing my “exercises”, and yes the air got calmer.
More ascending and descending while doing turns. All going good, although at one stage I had some problems keeping the ball on the slip indicator in the centre. I still sometimes have problems keeping it there, its a combination of aileron and rudder that is changing all the time, especially when the air is not still. But again its all experience !!!Then we did some slow flying. Normally we fly at about 60 m/h, now we slowed down the engine and raised the nose to stay at same altitude and went down to around 50 m/h. All controls are a bit “sloppy-er”.And yes we did two stalls, well Dave did them. Engine idle, pulling stick more and more, trying to stay at level flight, and then around 40 m/h we fell out of the sky  🙂
The first one was a nice gentle stall, and recovered easy. The second one was one of the wing drop ones. Dropped the left wing first, so correct with full rudder to the right, to try to swing the left wing to the right, back into the airstream.
I survived both stalls so happy about that !!And back to the airport, join the circuit by flying at 1500f AGL over the airport, down to 1000f AGL down wind, and final turn down to 500f AGL and descending to the strip. This time we staid a bit higher on purpose to get past some trees, as they were generating turbulence, but finally down to the air strip.
Yes a good lesson  🙂
