Flight Day 23  

Posted by y. 源

Two days ago, I managed to finish two sorties which were Nav Intro and Circuit 3.

Nav Intro was fun!!! Just like what I mentioned before, I was required to fly to Alor Setar airport and come back, passing through several way points. And of course, I had my instructor to guide me by my side, showing me the important landmarks in order to make sure we were at the right place. This sortie was sort of like driving to a new place with a map, you know. Seeing new things and identify them as what we see on the map. It's just that the scale I see from the sky is much smaller than I see on ground, obviously. Haha. The RT call was also a little different from the normal RT call I did for training area/circuits. However the weather became worse as we travel further into the mainland. Rain started pouring heavily and we had to divert to another way point to avoid flying into the thick dark cloud. Do you know what does it feel like when flying into that kinda cloud? Imagine you are in a washing machine. Turning round and round until you don't know where is sky and land. Coming back to land at lgk airfield was some a little strange to me because I usually approach from left base runway 03 and not right base. But I still landed anyway, will get used to it one day. =D

I was programmed to fly Circuit 3 (Solo) and Circuit 4 (Solo) actually. But due to some problem with the engine, I could only fly for 30minutes to complete Circuit 3. Here was what happened to me:

I was told to hold on ground for 10minutes due to airliners coming in. Later, I took-off as per normal, climbed through upwind, crosswind and then level off at downwind 1000ft while reducing power to 60%. After I made the RT call 'downwind for touch and go', the load meter (connected to power throttle) started to fluctuate in the range of 5%. Ok, this seldom happens, maybe the engine control unit, ECU is adjusting the power by itself. The aircraft is fine I guess. At late downwind turning into base leg, I reduced the power to 15% and started to descend for approach for touch&go. Now here is the fun part.

As I touched down, I retracted the flaps to 'Take-off' position, and then I increased the power slowly to full power configuration. But, when the load meter was showing approximately 80%, the RPM meter went to RED. For your info, this indicates that the propeller was over speeding!! This wasn't all. Immediately after that, the Oil Pressure warning lights went to RED too! And this indicates loss of oil and may lead to engine failure!!

I reduced the power. RPM went green (indicates no problem). Oil Pressure warning lights went to amber (indicates caution,or rather near to warning status). I did not want to take any gamble to continue my sortie. So I immediately reduce power to idle position, aborted the Touch&Go, and taxy back slowly to apron.

Luckily this problem did not occur to me in flight. Phew~~

Anyway, I reported the problem to the engineers and hopefully they will rectify the problem soon.
