Feature Article: Standard Rate Turns
All banks under the hood are at standard rate. Standard rate
turns requires two minutes to make a 360 degree circle. One minute
for a 180 and 30 seconds for each 90 degrees. The standard rate
turn for a given airspeed is indicated by the needle or by the
turn coordinator. The turn coordinator is the only true indicator
of whether the bank is left or right. (A necessary check during
spins) The angle can be estimated by dividing the speed by ten
and adding five. (Speed /10 + 5 = angle of bank) 85 knots airspeed
divided by 10 is 8.5 + 5 = 13.5 angle of bank. Set the estimated
angle on the AI and check with the turn coordinator. All climbs
and descents are at one bar width on the attitude indicator. From
low cruise both climb and descent at a given rate will closely
correspond to RPM changes by 100's. A power reduction of 500 rpm
gives 500 fpm descent.
