DZ
designated area where personnel and/or equipment are delivered by means of a parachute or free drop.
8 DZ selection factor
ADTMOAAS Airdrop Airspeed Drop Altitude Type of Airdrop Method of Airdrop Obstacles Access adequate Approach and departure routes Size of DZ
Airdrop Airspeed
determines the amount of time the AC is over the DZ. Measured in KIAS. Slower Airspeed=more jumpers
UH-60 Blackhawk airdrop airspeed
65-90 knots, planning 70 knots
CH-47 airdrop airspeed
75-110 knots, planning 90 knots
C-23 Sherpa
90-110 knots, planning 105 knots
C-130/C-17 personnel/door bundle airdrop airspeed
130-135 knots, planning 130 knots
C-130 CDS/Equipment/Combination airdrop airspeed
130-140 knots, planning 140 knots
C-17 CDS/Equipment/combination airdrop airspeed
140-150 knots planning 140 knots
C-17 Heavy equipment airdrop airspeed
planning 150 knots
Drop Altitude
measured in AGL from the highest field elevation on DZ. Round up to the nearest 50 feet. ex. 537 ft becomes 550 ft.
