A TAL abort takes about 45 minutes from launch to touchdown, which is short enough that the APUs can be left running for the whole duration of the flight. | A TAL abort takes about 45 minutes from launch to touchdown, which is short enough that the APUs can be left running for the whole duration of the flight. | ||
To initiate TAL abort in FG, the entry guidance computer needs to be set to the TAL landing site and as abort mode 'TAL abort' needs to be selected. In response to this, the HUD symbology changes to show key information needed to pilot the abort. Alternatively, the TAL may be selected on the SPEC 51 (OVERRIDE) display by first selecting TAL mode (item 1), followed by selecting ABORT (item 3). | To initiate TAL abort in FG, the entry guidance computer needs to be set to the TAL landing site and as abort mode 'TAL abort' needs to be selected.

The groundtrack map is most useful in aiming the trajectory and establishing a reasonable entry interface. | ||
