10-17. The JM is now ready to issue the first seven jump commands: GET READY. (See figure 10-1.) This jump command alerts the jumpers seated in the aircraft and directs their complete attention to the JM. The JM starts the command with their hands centered on the chest the fingers and thumbs extended and joined, and the palms facing the jumpers. The JM then extends both arms forward until the elbows lock with the palms facing the jumpers. The JM gives the command of “GET READY,” then returns to the start position.
