None/McD,
Thanks for your replies. Yes I’m fully aware that it’s not a radar image.
Let me expand upon my problem. We have just installed a Honeywell EGPWS onto a Level D simulator.
Everything works fine but, below 2000 ft the EHSI displays an effective, but inaccurate depiction of the terrain. I am wondering whether this apparent difference between the EGPWS and the visual scene (which is modelled from Satellite data and should therefore be fairly accurate) is due to the resolution of EGPWS i.e if the resolution is say 20 feet then low lying coastlines would appear to be incorrect.
I’ve searched, but cannot find a definitive statement on vertical resolution of EGPWS and was hoping that a true 'end user' may be able to advise me.
