john4pap Posted June 19, 2021 Posted June 19, 2021 Quote Elevation change warning is received when the altitude source selector HÖJD CISI is in mode LD and the barometric altitude is used. p.167 Elevation change warning seems to turn on regardless of altitude source. Impossible to know whether you're going to hit the ground or there's a change in elevation below you. Quote The altitude warning in case of a computer or flight data unit error, the indicator light will be lit with a solid light if the radar altitude is less than 80% of the set altitude. Altitude warnings can also be given during autopilot altitude hold modes. p. 168 It is unclear as to whether the warning turns on regardless of altitude source. I presume that it should only concern barometric. It appears that it is bugged since the warning light will keep on regardless of any changes I make in barometric pressure and altitude source. It only turns off when I switch the autopilot off. Turning the autopilot back on doesn't seem to trigger the warning light.
