Ryanair 737-200 GPS

Hi there

Would anybody happen to know what model of GPS were fitted to the Ryanair 737-200s that used to buzz about in the 1990s and early 2000s? Were they retrofitted as a standard fit after acquisition?

Thanks to anyone who can help. Fond stories of operating these aircraft always welcome. I miss the days when airliners had personalities.

" I miss the days when airliners had personalities."

personalities died with the jet engine I'm afraid - and the identikit designs from the 60's onwards

The link doesn't show up in the first post, here it is again: https://www.airliners.net/photo/Ryan...4-Adv/317571/L

Garmin's first model for the aviation market was the GPS 100... No idea if Ryanair used these but I don't think there were a lot of options out there in the early 90s.

Thanks! The google images of the GPS 100 don't seem to match the installed unit which is visible on the FO side of the pedestal.

I was looking at that same box... the problem is that equipment marketed to Boeing users was not marketed as extensively as the GPS 100 and later models. I wondered if it was a Trimble unit, but cannot find any matching options. Did Collins (who were the first to receive a GPS signal in 1977) build something for this market?

It could be a Trimble 2101 https://www.aircraftspruce.com/catal...900trimble.php

Well that 737-200 panel took me back a few decades! I only flew Omega, so could I ask what is the box visible behind the speedbrake lever, and is it associated with the small dial to the left of the ASI?

I flew Ryanair's 732s between '97 and '05. I cannot recall the make of the GPS, but it was not to be trusted. The only indication of a lost signal was a small light on its control panel, which was easily missed, so it had to be watched.
The instrument to the left of the captains ASI looks like some sort of left/ right indicator so may well have been linked to the GPS.
The box forward of the speedbrake was the Performance data conputing system. Came into service on Britannia's 732s in the mid 80's. The photo was of EI-CJG, which was originally Britannia's
G-BGYK.

Likewise - had to wait few years before our new build -300s were delivered to get dual FMS.

More useful was the egg timer!
