Yesterday: While doing a IFR practice approach (LPV) to EDMS (Straubing) the glideslope indication failed in about 1000 ft AGL and the Flight Director did not follow it anymore.
– First the GS indicators on the PFD disappeared
– a yellow “glideslope not available” message came up on the PFD
– both navigators showed “LPV” in green all the time.
We did a touch and go and a second practice approach and it seemed to work (but we broke off the approach to not get too close to the field un-announced).
