If you know the light posns in runway (object) coords all you need to know
is the lat, lon and alt of the centre/corner (0,0,0) of the runway.
Construct transformation matrix as is done for dynamic objects in main.cxx.
Rotate first for lat, lon and translate by Objtrans (see below).

This was dicussed earlier on this list.
I found one disdavantage of using multicast. My packet size or structure
kept growing as I added more computers on the network that are **not** image
generators but pcs used as flight test engineer station or fcs monitoring
station etc. Why should
Roman,
but I think that for IGs - best is multicast (no delays between channels)
Theoretically speaking, yes. But practically what delays are we talking
about even with a 10 Mbps dedicated network. We will be fast enough for
realtime. Synchronisation problems would not happen at the network

I've noticed both th c310 and c182 give a problem at load time.
The problem is related to the retractable landing gear because it dumpt

A test with the c310 changing RETRACT to FIXED did actually fix the
problem.
Alright, that one is fixed now. Thanks.

Yes I mean multicast and not broadcast. The destination address is the group
still, unless I have different multicast groups - one for IG, one for the
engineer etc. That would be a waste.
