1 1 Warrior Logisticians 1 Aerial Delivery Drop Zone Selection

2 2 Warrior Logisticians 2 Aerial Delivery Terminal Learning Objective: In a class room environment, be able to explain what types of drop zones (DZs) there are, what they are used for, and how to select different DZs IAW FM (FM 57-38)

3 3 Warrior Logisticians 3 Aerial Delivery Safety Requirements

4 4 Warrior Logisticians 4 Aerial Delivery Environmental Considerations

5 5 Warrior Logisticians 5 Aerial Delivery Size and Selection: Determined by Commander of Airlifted Forces, Air Component Commander and by Supported Force Commander

6 6 Warrior Logisticians 6 Aerial Delivery General Area for Airborne Operation: Ground Commander responsible for the decision to accept the recommended DZ and obstacles

7 7 Warrior Logisticians 7 Aerial Delivery Eight Factors in Drop Zone Selection: Airdrop airspeeds Drop altitude Estimation of DZ time requirements (# and types of loads or personnel to be dropped)

8 8 Warrior Logisticians 8 Aerial Delivery Eight Factors in Drop Zone Selection (cont): Access Avoid major obstacles to personnel and equipment between DZ and the objective Ensure adequate routes are available for equipment recovery

9 9 Warrior Logisticians 9 Aerial Delivery Eight Factors in Drop Zone Selection (cont): Size of Drop Zone (Formulas) −There are several formulas used to measure drop zones. − Specific formulas can be found in FM 57-38

10 10 Warrior Logisticians 10 Aerial Delivery Eight Factors in Drop Zone Selection (cont): Approach and departure routes Enemy situation and location Terrain higher than the DZ No-Fly areas Obstacles to the aircraft

11 11 Warrior Logisticians 11 Aerial Delivery Method of delivery (Low/High Velocity and Free Drop): Obstacles Trees, Water, Wires, Populated Areas Others – Barbed wire fences, swamps, rocks, ditches, gullies, and steep inclines

12 12 Warrior Logisticians 12 Aerial Delivery Drop Zone Survey (3 types): Complete Survey Primarily done in Peace Time, not in combat Used by any airborne force Done well in advance Ingress and egress routes Physical inspection

13 13 Warrior Logisticians 13 Aerial Delivery Drop Zone Survey (cont): Tactical Survey Used during exercises or contingencies Restricted to resupply or single ship airdrops Physical inspection Chart showing flight route

14 14 Warrior Logisticians 14 Aerial Delivery Drop Zone Survey (cont): Safety-of-Flight Review Survey Requested by SOF Restricted to special operations Chart showing approach and escape corridors Commanders accept responsibilities for injuries and damage to equipment

15 15 Warrior Logisticians 15 Aerial Delivery Drop Zone Markings Minimum standard Point of Impact (PI) through use of Raised Angle Marker (RAM) Additional markers increase accuracy Limited visibility RAM must be illuminated Drop airspeeds: Published in appropriate manuals FM (FM ) Drop Zone Survey (cont):

16 16 Warrior Logisticians 16 Aerial Delivery Types of Drop Zones: Area Drop Zone Circular Drop Zone Random Drop Zone

17 17 Warrior Logisticians 17 Aerial Delivery Types of Drop Zones (cont): Area Drop Zone (draw a diagram) (cont) Changes in ground elevation of 300 feet or 90 meters Distance of drop sites from line of flight should not exceed ½ nautical mile or 1 kilometer

18 18 Warrior Logisticians 18 Aerial Delivery Types of Drop Zones (cont): Circular Drop Zone (draw a diagram) Radius of a circular drop zone corresponds with/to minimum required distance from the PI to one of the trailing edge corners Drop zone box must fit in circle

19 19 Warrior Logisticians 19 Aerial Delivery Types of Drop Zones (cont): Random Drop Zone Random approached DZs are square or rectangular and large enough to permit multiple run in headings Any axis may be used PI is in the center of the drop zone

20 20 Warrior Logisticians 20 Aerial Delivery Types of Release Systems –Computed Aerial Release Point (CARP) –Ground Marking Release Point (GRMS) –Verbal Initiated Release System (VIRS)

21 21 Warrior Logisticians 21 Aerial Delivery Types of Release Systems: Computed Aerial Release Point (CARP) Air Force Only Requires DZ marking (RAM) Radar system identifies load release point

22 22 Warrior Logisticians 22 Aerial Delivery Types of Release Systems (cont): Ground Marking Release Point (GRMS) Army marking system Requires DZ marking (VS-17 Panel) Spotter in air craft spots marker and orders release

23 23 Warrior Logisticians 23 Aerial Delivery Types of Release Systems (cont): Verbal Initiated Release System (VIRS) Army VIRS Air Force VIRS Verbal commands guides pilot Does not requires DZ marking

24 24 Warrior Logisticians 24 Aerial Delivery DZ Markings: Raised Angle Marker (RAM) Used for CARP

25 25 Warrior Logisticians 25 Aerial Delivery DZ Markings (cont): VS-17 Panels Inverted L (4 panels) −Approach panel (50 meters in front of corner panel) −Corner panel (100 meters left of release point)

26 26 Warrior Logisticians 26 Aerial Delivery DZ Markings (cont): VS-17 Panels (cont) Inverted L (4 panels) −Alignment panel (50 meters left of corner panel) −Flanker panel (150 meters left of alignment panel) Visible lighting systems

27 27 Warrior Logisticians 27 Aerial Delivery DZ Markings (cont): Rotating beacons if required Smoke Mirror B2 light gun, flares, fire pots and flashlights

28 28 Warrior Logisticians 28 Aerial Delivery Check on Learning
