Yes we do use as aircraft EGPWS hardware and again, yes we are talking to Honeywell and I totally concur that they are very helpful.
With GPWS it was a lot more straightforward to introduce ‘glass mountains’ as the terrain was controlled by the simulator and/or visual system as opposed to the Honeywell database.
With regards your comment “poor standards of simulating aircraft geographic position”. The big problem facing the industry is that all the different nav data sources used within the simulator do not necessarily agree amongst themselves. There are geographical errors/differences even between all the principal nav data suppliers for an identical facility. This is compounded because Honeywell are reluctant to reveal the source of their EGPWS data. This problem is further compounded when constructing visual databases when their geographic data also differs from the nav data!!!!
Very interesting topic though.
