The primary flight display provides a summary of all GNC relevant parameters. Its core is the ADI ball on which the attitude of the Shuttle in the selected coordinate system is shown, surrounded by tapes for velocity, alpha, altitude and vertical speed. In the lower half, an accelerometer and the course deviation indicator are provided along with mission-phase specific alphanumerics. | |||
Error needles on the ADI ball provide 'fly to' indicators based on the current guidance computations which can be used when piloting the Shuttle in CSS mode. | |||
The PFD is a complicated instrument in which the meaning of various readings depends on switch settings and mission phase (for instance, the ADI reference can be standard pitch/heading/roll as for an aircraft in the final phase of the flight as well as inertial or LVLH in orbit; the range of the error rate display is also selectable, the accelerometer will show Nz during entry and TAEM rather than linear acceleration during launch,...) - so make sure you understand what it is showing before using its information. | |||
Most of the original functionality is implemented in FG. | |||
