T-38 was 4,000 feet to 7,500 feet for landing and around 2,300 feet to take off.
F-5B and T-38 have different aerofoils. Aerofoils!! Who ever uses that in normal speach. What I should have written was that they have different wings and the F-5B had/ has leading edge slats and trailing edge flaps.
Found some details..
Takeoff run for F-5B was 2200 feet with two Sidewinder missiles. Landing run from 50 feet with braking parachute was 3800 feet
Quote from
Thornton Aircraft "Take-off and landing performance of the F-5 is superior to that of the T-38 due to the drag chute and larger wheels and brakes of the F-5. In addition, the F-5 exhibits less buffet in the traffic pattern due to its leading edge flaps."
