In a standard rate turn in a C172, defined as 180 degrees/min (2 minute turn) the silhouette on the indicator will be pegged on about 20 degrees. It only really shows the rate of turn. The Bank angle itself is not an accurate indication. Older instruments will only actually take into account yaw, a newer turn indicator also includes the roll rate in its interpretation of the situation.
You can fool a turn indicator into showing a higher bank angle than the actual angle. Get into a standard rate turn, keep the wings pegged at 20 degrees and increase the G-Loading with a backpressure and throttle. Although your wings are still at 20 degrees it will show a higher angle as the RATE of turn is more than a standard 180 degrees/minute. Trevor Thom never mentioned that till about book 12 I think it was, but still my instructor used to drill it in ;) Alex On 30 Jun 2010, at 23:24, Stuart Buchanan wrote: > On Wed, Jun 30, 2010 at 4:12 AM, Jörg Emmerich wrote: >> Hi Stuart and Heiko, >> I seldom saw such a fantastic responsiveness in my life - thanks a >> million.
