Touch Down Predict Routine Mode 

Touch Down Predict Routine Mode

Provides an on-board capability for predicting the half-lift touchdown point on the basis of ground-computed orbital initial condition data and a selected trial retrograde time. The calculated time-to-go to retrograde and the associated retrograde initial conditions may be automatically transferred to the Time Reference System (TRS) and re-entry program, respectively, for subsequent initialization of the re-entry mode.
