 While usually mission control would perform such tasks and uplink the results, the Shuttle has an on-board computer for calculating burn sequences to reach orbital targets. This functionality is controlled via SPEC 34.

 In addition, in the lower right corner, the current state vector of the Shuttle as known by the avionics is displayed.
-As of June 2016, the implementation in FG supports a quasi-Hohmann transfer computation. From a lower, reasonably circular orbit, item 28 calls a numerical trajectory solver which fits burn parameters to reach the target. The results are stored as PEG-7 targets and can directly be used in the MNVR display. Most other options to tweak the T1 and T2 targets are currently not supported.
