CAUTIONAll jumpers on the aircraft must enforce rip cord handle awareness at all times. Once the USLM is hooked up to the anchor line cable, the nonstatic line hand will protect or cover the rip cord handle.“CHECK EQUIPMENT.” JMs will lean left then lean right and observe the stick of jumpers as they check their equipment. Once all movement has ceased, both JMs will give each other a thumbs up. This tells the other JM that their jumper’s equipment is good and they are ready to proceed. After the thumbs up has been issued, both JMs will check their own equipment.“SOUND OFF FOR EQUIPMENT CHECK.” This command is passed from the forward to the aft portion of the aircraft by each jumper.10-72. The aircrew completes their six-minute slowdown checklist:Aircraft deck is set between six and seven degrees.Aircraft slows to a drop speed of 130 knots (plus or minus three knots indicated airspeed).Air deflectors are deployed, and troop doors opened.The loadmasters give control of the doors to the JMs and takes a position between both jump doors.Once the safety and technical inspection of the paratroop door is complete, the loadmaster informs the JMs, “ARMY YOUR DOOR.”The JM needs to confirm through the loadmaster, the aircraft has slowed to drop speed before assuming control of the paratroop door. This signal can be predetermined during the AMB or aircrew and JM briefing before flight.Note. Jumpmasters will not assume control of the aircraft paratroop door until the loadmaster has confirmed the aircraft has slowed to 130 knots indicated airspeed.
