Question About GPS On Aircraft

Thu Feb 24, 2005 5:01 pm

Hi everyone,

I have a few questions concerning GPS on aircraft. Almost absent 10 years ago it has become a norm. I find long haul flights with GPS far more interesting than without. I remeber flying back before the mid 1990's and it was almost frustrating not knowing where you were during long haul flights. the once you have PTV, I know many people that like me can spend hours looking ah the GPS

1)Could anyone possible tell me since when it was introduced into airliners and which was the first one to introduce it ? (SQ would not surprise me)

2) All GPS on airliners seem to have the same layout. Which company provides the program for the GPS?

3) While in a GVA-LIS TP flight there was a GPS, its not the case on all short haul flights. They could display them as its always interesting to know where we are

I think you are referring to the "Airshow" software. This is not necessarily linked to a GPS at all. Many planes don't have GPS. In these cases the Airshow is connected to the inertial navigation platforms.

2) The airshow software is made by Rockwell Collins: http://www.airshowinc.com/

3) There is a cost involved but I agree with you. As PTV and ceiling LCDs become cheaper they will also become more pervasive.

I flew on a Britannia Airways 737-200 in the 1980s which had an altitude disply on the ceiling that passengers could watch. Whatever happened to that?

This reminds me of the concorde's Mach o' meter placed in the aircraft. I would have loved to follow the GPS on a concorde and see how fast it crossed the atlantic

RootsAir: As Starlionblue said, don't get confused with "Airshow" vs GPS. If passengers were to believe that the pilots were looking at the same maps and information that they could see, that could get interesting. Modern airliners usually integrate GPS into the FMS. While, I'm sure that GPS can be used as an input to the Airshow, the two are otherwise unrelated.

What about the altitude shown on the Airshow screen? It's often not an even Flight Level-- where's it come from?
