P66

Program: P66 Landing Phase (ROD)

Purpose: To control the LM in final phase of landing. With Mode Control in Auto
forward and lateral velocities are nulled. When in Manual the inertial attitude is
controlled by the astronaut. Throttle is calculated and Rate of Descent (ROD) is
controlled by toggling the ROD switch.

P66 is started automatically by Landing Auto Modes Monitor routine when targeted
conditions for P64 are met or the ROD switch has been activated after P63.
