133 mph EAS * .869 = 115.6 KTAS
SMOE @ 20000 feet from our Standard Atmospheric Data = 1.3700
Radius = (VKeas * SMOE)^2 / 11.26tan <theta>
Radius = {115.6*1.3700}^2 / 11.26tan <68>
= 899.97 or just 900 feet @ 20,000 feet
Rate = 1091(tan 68 ) / (115.6KEAS*1.3700)
=
17.05 degrees a second
= 360/17.05 = 21 seconds to complete a 360 degree turn at 20,000 feet
115.6*1.3700 = 158.4 KTAS
Looks like 21s when we ask the US Navy or use any universal turn performance chart!!
Ha ha ha
