21-20. The location selected where the first bundle or parachutist should land is known as the PI. The PI should be located along the DZ centerline. However, due to the tactical situation, the PI may need to be located near a wood line. The DZSO or DZSTL uses a buffer zone of 100 meters on each side of the DZ during personnel drops for safety reasons. The PI location for GMRS, VIRS and WSVC is 100 meters in from the leading edge centerline for personnel. The CARP PI is designated on AF IMT Form 3823.21-21. To compensate for wind drift, the DZSO or DZSTL moves from the desired PI into the wind the number of meters calculated using the D = KAV formula. (For example, if drift equals 350 meters from the PI, the DZSO or DZSTL faces into the wind and walks 350 meters in a straight line.)21-22. To compensate for aircraft forward throw, the DZSO or DZSTL faces the back azimuth of the drop heading and walks the appropriate forward throw distance to the release point.Note. A parachute’s K factor is based on the parachute’s flight characteristics, not on its mode of use. According to TM 4-48.04, the K factor for the T-10 series parachute used in the cargo mode is the same (3.0) as for personnel drops using the T-11 ATPS parachute.
