Listed in notes for 1.1.0.8 Patch
- HARS navigation is defaulting to active at ramp start. With the HARS mode active, you will not get any FPM/VVI in the HUD, and you will not be able to arm the EAC. If you switch from HARS mode to EGI mode after complete INS Alignment, then the FPM/VVI returns, and you can arm the EAC.
I think this might be the prob ??
