Precision Aerial Delivery System's Mission Planner enables aircrews
to plan and initiate load release at a precise Computed Air
Release Point (CARP), or within a Launch Acceptance Region (LAR),
through application of accurate, Precision Aerial Delivery component
modeling. The system was developed in the past six years under
contract for the US Air Force, in coordination wit the US Army.
Over 60 systems have been delivered to US Air
Mobility Command and other DoD units. Additional systems are
in production to assist in high-altitude airdrop operations
and precision personnel insertions. The model parameters include
aircraft position, altitude, airspeed, heading, ground speed,
course, onboard load position, roll-out/exit time, decelerator
opening time, trajectory to stabilization and descent rate.
Descent trajectory is calculated to each of the planned points
of impact, compensated with environmental effects such as atmospheric
pressure, three-dimensional wind and density information measured
by dropsonde deployed from the aircraft just before the cargo.
planner is used to program the drop and target altitudes, steering
waypoints, wind magnitude and directions as a function of altitude,
opening altitudes, and GPS "hot start" information.
Mission planning is done before the flight. Information can
be updated in-flight and just before the drop, from the aircraft
avionics and from dropsondes and manually, using wireless link.
This integrated technology allows rapid pre-flight programming
and in-flight mission, threat, and terrain/environment changes
for immediate reaction by the user. The mission planner uses
a Panasonic CF-29 Tough Book laptop computer with specially
ruggedized 'high altitude' hard drive.
