A test pilot on the F-16XL test team is told by the contractor's structural engineers to fly at a constant 300 KEAS (knots equivalent to airspeed) to get the desired test points for the f-16XL's flutter limits. The position error correction is -10 kn for the F-16 at 300 KEAS.

(a) What indicated airspeed must be flown in knots to get data at 20 000 ft pressure altitude? (319 KEAS) (Assume V[sub cal] = v[sub e] and iterate)

(b) What type of velocity will the ground-based radar record when the pilot is at the test point in part a and there is no wind? (V[sub t] = V[sub g]). What if there is wind? (V[bar sub g] = V[bar sub t] + V[bar sub w].

(c) At what true velocity (in knots) must the pilot fly to conduct a test point at 30 000 ft on a standard day? What about at 10 000 ft?
