If you use SHIFT +Z then it gives the height AMSL of the eyepoint = position of the aircraft you are flying. For the C172 you subtract 3.7 from the figure to get ground height. That means with my scenery you are at a true height of 33ft - which is correct for the flatten command I have used. With Gary's scenery he has stayed with the default FS airfield height of 55ft AMSL. bones -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of = FrankTurley@xxxxxxx Sent: 31 December 2004 12:53 To: jhb_airlines@xxxxxxxxxxxxx Subject: [jhb_airlines] Re: EGNS Scnery =20 In a message dated 31/12/2004 04:03:36 GMT Standard Time, bones@xxxxxxx = writes: A clue. If you drop 20 feet would I be right in saying that whilst on the = runway your height is 55ft AMSL and then you drop to 33ft AMSL on the = taxiways? If so then it would suggest that something is taking priority over my scenery and resetting the runway heights back to the default 55ft.

Either that or you have an AFCAD file somewhere for EGNS that is active above my scenery (Ultimate = =3D Traffic and Flight 1 are both possible culprits here). Just check that in my IoM scenery folder you have the EGNS_F.bgl (which = =3D is the flatten command) and also, if using FS2004, you have the AFCAD = file AF2_EGNS.BGL. The latter is part of the FS2004 upgrade and wasn't =3D = present in the original FS2002 scenery release. bones Bones, =20 1. Results using your IOM (yes I do have the EGNS_F.bgl and the =20 AF2_EGNS.bgl) using Shift+Z in the C172 give a uniform 36.7FT across the field. =20 2. Same test using Garry's EGNS gives 58.7FT. However, in this mode, I = can =20 see the red letters of the AI traffic, but I can't see it - I guess its buried. =20 Frank T.
