Some basic figures might help ; 180kts ,45*bank,Vs 137kts(115 basic)180* turn diameter 5800ft,G1.4,Time 30secs.
50*Vs143kts G1.6,D 4840 ft, T25 secs;/; 55* Vs152 Kts ,G 1.7 ,D 4100 ft, T21 secs;/;60*Vs 163kts, D 3330 ft, T 18 secs;/;63* Vs 172 kts, G 2.2, D 3000 FT,T15 secs..These figures are taken from a website and Nomogram of `Turning Performance`,and for level flight,but close enough for 8-10* glide angles.
At the start of the d/w leg R3 was 5000 +_ 100 ft from RW31; at the end ,commencing the turn ,he was appx 4300 ft displaced,with an approx. G/S of 190 kts,and a x/wind.,both of which had not been compensated for,unless he was using aggressive bank angles,and an increase in airspeed to compensate. Putting the gear/flaps down was the end-game.....
IF otoh he had turned for a L/H D/W for R/W 01,it would have been `easy`,and may have also worked for r/w 31,as his `offset`track would be approx. 5300ft.... Speed is life.....lower the nose in gliding turns....
OK,bonedome on,nose down, avoiding incoming ,!!
