Terrain Display no longer working after HF4

Recommended Posts

I just installed HF4 and I am experiencing a strange failure of the Terrain display. When I switch on Terrain via the EFIS button, the entire display (within the compass rose) fills in with magenta. I recall the display working properly with HF3 installed. Anyone else seen this odd behavior?Bill Rowe

I have sometimes a full green pattern on the entire range for maybe a second when in flight and with no obstacles.It came on 2 or 3 times during a flight. Also for me it was only after hf4.

Same for me, but at lower frequencies.

On my last flight with HF4 I had the same thing.I was on a flight from EGSS to EHEH. Somwhere above the channel the captains ND turned green. I switched on first officers ND and it worked normal. Then I changed captains ND from 10 or 20 to 80 and the green was gone. But as soon as I reduced the range everything was green again for the remaining flight. The route was: CLN L620 REDFAFlighttime was about 44minutes, it happened about 15 to 20 minutes after takeoff.Reagrds,Jonathan Huschle

Mhhh.... I must check my settings, also on my system the green pattern appear on the sea, as far as I can remember there is a setting about the terrain display, I'll check as soon as I can.

On my system it starts normally without any test (as it is on real). The test is only done by pushing EGPWS TEST.
