Thus, Pi x D = 12566 feet or 2.07 Nautical Miles. The turning radius for 200 KTAS, 30 degrees is about 6000 feet or 3 times that of a 60 degree turn.

When one studies the SUN 100 course, it can be shown that there are at least= 4 turns:
Off the runway, East bound, then to South bound, 92 to 178 degrees (86 deg t= urn);
East corner turn to West, 178 degrees to 275 (97 deg turn);
West corner to NE, 275 to 41 (126 deg turn); and finally
NE back to the runway, 41 to 92 (51 deg turn) for a total of 360 high speed=20= turning degrees.

Using Fig 2.29 (Constant Altitude, Steady Turn Performance) in "Aerodynamics= for Naval Aviators" (NAVWEPS 00-80T-80) on can find that at 200 KTAS and a=20= 60 degree banked turn, the radius is 2000 feet.  Thus, Pi x D =3D 12566= feet or 2.07 Nautical Miles.

The turning radius for 200 KTAS, 30 degrees is about 6000 feet or 3 times th= at of a 60 degree turn.  Thus, taking turns at 30 degrees would add 6.2= NM to the course.
