ultrablue2258 Posted December 8, 2019 Share Posted December 8, 2019 I've noticed that in the hornet that your standby altimeter does not always match your hud altimeter. This should not the case. In a test mission with the hornet spawning at 24,000ft, the F2 altimeter shows 23,992ft; the HUD altimeter shows 23,650ft; the altimeter gauge shows slightly less than 23,500ft. I've attached the track file to show this issue. The barometric pressure is 29.92 with no winds. I have noticed this happening no matter the environmental factors.FA-18AltitudeMismatch.trk Link to comment Share on other sites More sharing options...

Is one adjusting for ASL and the other not?

Frederf Posted December 9, 2019 Share Posted December 9, 2019 The HUD shows ADC calculated baro alt while the backup system is a self-contained simpler system that is subject to all sorts of alpha/beta/lag/temperature/mach/whatever errors that the ADC-driven value isn't (or rather the ADC corrects for with some success). It's normal for the ADC value and the standby altimeter to differ. 150' at 23-24kft sounds like a good deal of agreement for the backup altimeter to me.
