| Message | (Monday 1935) I did CH21 early this afternoon and it was a rather demanding flight. First I did all the aerobatic sequences and after that it was time for my first vertical maneuvrs. First a Vetical 8, where you basically fly the figure 8 by doing half a loop, half a roll, a full loop, and then another half roll and half loop. After that it was time for the vertical roll. You enter the vertical roll at full blower and 280kt and pull 5g to get into the vertical. Then as soon as you get there, you unload the g and put on full aileron deflection to roll around the vertical axis. After the IP demonstrated one for me, he asked whether I had any questions. I replied "I have no idea what the hell just happened there..." The vertical roll is very overwhelming the first time you experience it. I did one myself and then a barrel roll afterwards. I flew us back home and then it was time for my solo flight. So I flew out in deteriorating weather, asked ATC for a cloud break up because of cloud cover, and when I got on top of the clouds I was between two layers, which weren't very far apart, so I didn't have enough space to do my aerobatics. So I decided to get a cloud break down and fly back to base for some pattern work. I did an AoA approach, an overhead break and a closed pattern for a PFL and then landed and saved the flight time for another flight. So tomorrow I have CH22 and the remainder of my solo CH21A. My IP tomorrow is the base commander, so I'm pretty anxious about it. Apart from the fact that he's a Colonel, he's also a very strict man and only a couple of students have flown with him before. On tomorrow's programme, among other things, is the maximum performance turn for the first time. It's a turn where you pull maximum sustained g. The way to do it is to find the right speed and then pull hard enough to put the aircraft right on the edge of stall, where it's giving you max lift. It's funny how different you fly on 2B than what we've done up until now. The T6 has a "stick shaker" which is a device that shakes the stick when you reach 15.5 AoA, warning you that you're approaching the critical AoA (18) and when you get shaker is normally the time when you would unload the g to get in the "safe" area of flight again. But in 2B, for instance in the maximum performance turn, you go to shaker, and then you pull even harder until you have 17 AoA - and keep it there. That's the way you fly a fighter to get the maximum performance out of it. It's exciting stuff and it teaches you alot about energy management and how to get the best out of any aircraft. So now I'll do some studying and then it's off to bed to be as rested as possible in order to withstand the g's tomorrow. One hairy moment that I had today was when I lined up on the runway and powered up to 30% on the brakes to check the engine before take off. The runway was icy and the plane started skidding, so I just released the brakes and did a rolling take off. Even worse was when I landed and the plane was skidding over the ice as I braked. The T6 has very high tire pressure, intentionally in order to reduce the chances of aqua-planing in deep water. It works really well but makes life a bit too "exciting" in icy conditions./GEA |
