Considering flight safety as well as ground safety, the DZSTL coordinates closely with the DZ safety officer to observe and evaluate all factors that could adversely affect the safety of the airdrop operation. If radio contact is possible, the DZSTL will pass surface wind information and limited weather observations to inbound aircraft and units, as required. When radio contact is not possible, the DZSTL must ensure DZ markings are properly displayed as pre-briefed to convey the appropriate message to aircrews.
Taking into account both airborne and ground safety, the DZSTL collaborates closely with the DZ safety officer to monitor and assess all factors that might compromise the safety of the airdrop operation. If radio communication is feasible, the DZSTL will share surface wind information and limited weather observations with incoming aircraft and units as needed. In the absence of radio contact, the DZSTL must guarantee that DZ markings are accurately displayed in accordance with pre-briefed instructions to convey the necessary message to aircrews.
