I'm hijacking the thread back....
FWIW, here is a table of turn radius for a combinations of bank angle (degrees) and TAS (kts):
10 15 20 25 30 35 40 45
150 1.86 1.22 0.90 0.70 0.57 0.47 0.39 0.33
180 2.67 1.76 1.30 1.01 0.82 0.67 0.56 0.47
200 3.30 2.17 1.60 1.25 1.01 0.83 0.69 0.58
250 5.16 3.39 2.50 1.95 1.58 1.30 1.08 0.91
300 7.43 4.89 3.60 2.81 2.27 1.87 1.56 1.31
340 9.54 6.28 4.62 3.61 2.91 2.40 2.01 1.68
From here it is a simple exercise to calculate the instantaneous turn rate whereupon one may verify the
reasonableness of the following aide memoire (which I must confess I don't find particularly useful as I think in terms of
track miles not
time):
Bank Angle for Rate One turn = TAS/10+7
With the above, it is also a simple exercise to calculate track miles in the turn (~=3*turn radius), whereupon with an appropriate figure to hand of the rate of deceleration you are going to effect (clean & level + no speedbrake, clean & level + speedbrake, clean & descending + speedbrake, dirty etc etc), one may calculate the point at which to turn to hit your chosen gate.
