[BUG] - FMA Speed Control Modes Magenta/White #1664

Open MCCVeen opened 4 months ago

MCCVeen commented 4 months ago

Describe the bug

FMA PITCH/THRUST annunciations should be in magenta whenever FMS SPD is active, and when speed is set manually on FCP but matches FMS SPD it will turn magenta. Currently, the PITCH/THRUST annunciations turn white whenever PROF is not engaged, which is incorrect. In the case of the FMA displaying Magenta speed reading and White THRUST annunciation, FMS SPD is not active and speed is manually selected on FCP which happens to match the FMS SPD.

Steps to reproduce

To reproduce PITCH/THRUST annunciations incorrectly turning White when not in PROF:

-Set up the FMS for a route with FMS SPD and PROF calculations

-Push FMS SPD with any other altitude control mode than PROF

-Watch PITCH or THRUST annunciation for Speed Control Mode turn White instead of Magenta.

To reproduce FCP Speed not turning Magenta when matching FMS Speed:

-Continue from previous situation, now pull the FCP Speed knob and set Speed/Mach to match the calculated FMS Speed, it should turn Magenta if it matches however in the TFDi it incorrectly remains white. (This should also match for if the FCP altitude matches PROF but PROF is not engaged)
