The Transatlantic Abort Landing (TAL) is the next option in terms of energy required after the RTLS abort. It is based on bringing the Shuttle onto a ballistic trajectory that doesn't quite reach orbital speed and aim the trajectory at a landing site on the other side of the Atlantic ocean - dependent on launch course, there are several sites available. | The Transatlantic Abort Landing (TAL) is the next option in terms of energy required after the RTLS abort.

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