Last week on Thursday I went for my third Navigation Flight with my instructor Shepp, we flew from Bankstown to Goulburn (Bankstown, Cadmen, Mittagong, Goulburn, Taralga, Bindook, Warragamba Dam, Bankstown). I took off for the first time in the center runway, the big, long, wide and nice runway that the Jets use. I made a huge mistake in my planning; you can imagine my planning sheet, a whole A4 page full of numbers for the timing, tracks&headings and heights. Well, the case is that I miswrote a heading of 227º instead of 196º and I ended up somewhere in the Blue Mountains, 15NM* off track after only 27NM (15 Minutes at 110Kt*). This was a good chance for me to perform, for the first time in a real situation, the Lost Procedure! This consists in checking which actual heading one has been maintaining and for how much time has elapsed since the last position confirmation check, and then draw a circle of R=5NM around the estimated position. Then you try to identify landscape features and compare them with your map. But it makes me reeeeally nervous to make calculations inside the aircraft, because think of what the first thing you’re used to do when you get lost driving a car… You just pull over and stop, but you can’t stop an airplane, so every second counts!
Succeeded to orientate myself, after a while we finally got to Goulburn, a very small runway in the middle of a small deserted area between mountains. We changed opinion several times on which runway to land after checking the windsock, since the wind was variable and just after having decided to land on RWY 22 another aircraft was preparing for taking off from 04 (opposite side of the same runway, since 040º and 220º are reciprocal). On CTAF Aerodromes (Common Traffic Advisory Frequency – Radio Communications) there’s no ATC (Aircraft Traffic Control, in other words, control tower), so nobody tells you where you have to land and you have to make your own decisions… At your own risk. When we finally attempted our landing we had to go-around (abort landing) because there was full of black birds flying very low over the runway! We made two more circuits and each time we had to go-around, so we finally headed back to Bankstown. On the way I learned how to use a VOR, a navigation aid which not only indicates you the direction to the antenna on the earth surface, in other words, your heading, but also your actual track, so you can determine you are drifting in relation to the ground. Once in the Training Area boundaries near Bankstown we practiced a few Stallings and two-three circuits before landing pacefully on 11R. So, 2,9 hours for my logbook.
After de-briefing I went with Luke to taxi a Beechcraft Duchess, a very nice Twin-Engine which I won’t be flying until my CPL training. Luke told me a secret, which indirectly means very good news for me, which I won’t mention here (yet)!
