Dozer Posted December 22, 2010 Report Posted December 22, 2010 Another minor bug: the turn indicator doesn't seem to indicate turns greater than rate 1.I'm in a very tight spiral dive here, but the turn indicator still shows I'm doing a standard turn (180° per sixty seconds, I think). The aircraft symbol surely should be able to move beyond the marks that indicate a standard turn, or how do you know you're turning too tight?(hope this doesn't come across as nit-picking, but IFR is what I like, so I'm mostly looking at all the instruments...)

Goran_M Posted December 22, 2010 Report Posted December 22, 2010 The turn indicator, from what I remember in the POH, only shows a turn indication and that turn indication only goes up to 20°. The instrument only tells you that you are in a turn. For the angle of turn or any details of the turn, the artificial horizon should be used.I will check into it, though. Quote
Dozer Posted December 22, 2010 Author Report Posted December 22, 2010 OK, thanks for the reply. I thought it was (what I now have learned is called) a Turn Coordinator, which indicates rate of heading change (not angle of roll). With a turn coordinator, if you line the wingtip up with the mark, you're doing a Standard Rate turn (2min for a complete 360° turn) which is used in some instrument flying procedures such as holding patterns and instrument approaches. And also useful if your compasses are all broke - you can make heading changes using the TC and a stopwatch. Quote
Ben Russell Posted December 22, 2010 Report Posted December 22, 2010 +1 Dozer.An instrument that cant show you when you're over and by how much you're over, is useless and will do nothing but induce PIO. Quote
Ben Russell Posted December 23, 2010 Report Posted December 23, 2010 Google images search reveals no evidence that the gauge can indicate when you are turning too quickly. What a stupid design. Quote
Goran_M Posted December 23, 2010 Report Posted December 23, 2010 Just looked through the documentation in the POH, my notes from my flying school days and wikipedia. http://en.wikipedia.org/wiki/Turn_coordinatorAll co ordinated turns are to take 2 minutes. They are not supposed to be "rushed". It sucks that it's capped, but that's the way it was. I might actually check out if the "plane" stops moving past the 20° mark. If it does keep going (so as to accurately hold the aircraft at a non capped marker point) I'll fix it for the next update. Quote
mattag08 Posted December 23, 2010 Report Posted December 23, 2010 This is incorrect. Turn Coordinators display rates greater than 3*/sec. What should happen is the turn coordinator should display rate of heading change and will peg out at about 5*/sec with the artificial airplane pointing its wing to a point that is about 50% further than the standard rate marking. Rate of turn (angular rate or heading change per unit time) is indirectly related to bank angle, but is also a function of speed, so you cannot say that the turn coordinator should or should not peg at 20*.
