RuskyV Posted August 29, 2022 Posted August 29, 2022 As the title says when switching between these two modes a few times shows around a 2-3 deg heading change. possibly a small bug?
Bob1943 Posted August 30, 2022 Posted August 30, 2022 Just guessing here, but true airspeed might be based on the heading of the nose of your plane through the air mass, while ground speed is based on your track across the ground. So, if you have a crosswind component, those 2 directions will be different. 1

I'll double check to be sure first
Solution Frederf Posted September 1, 2022 Solution Posted September 1, 2022 In the GND SPD switch mode it changes to INS GS for speed and also INS track (instead of heading) for heading. CAS: speed KCAS, heading magnetic TAS: speed KTAS, heading magnetic GND SPD: speed INS ground, ground track The heading tape HUD element can (will) change switching between CAS/TAS and GND SPD but will never change switching between CAS and TAS.
RuskyV Posted September 1, 2022 Author Posted September 1, 2022 Brilliant thanks for clarifying Frederf
