What is this instrument?

Can anyone help with identifying this please?

It is the screen for the FMS (INS/GPS) input that is on the navigators station. The nav would input the route and the picture was between the pilots...

Thanks Andy

Were they fitted with TCAS in the latter days? I guess that'd show on there too if they were?

[Tonkenna]

TCAS was fitted at the same time... the contacts were displayed in the VSI rather than the FMS screen.

Oh, OK. I'm surprised they went for the VSI...I guess there isn't anything much else to overlay on that!

[Tonkenna]

Well to be honest the VSI is a vital part of TCAS so it actually makes perfect sense... it was a good instrument.

You can get TCAS in two forms.
1. Integrated into the glass cockpit display.
2. As a separate instrument combined with the vertical speed indicator. Which as Tonks says makes sense as the TCAS RA (Resolution Advisory) tells you to climb and descend. In the attached image the pilot has been told to climb at a rate that puts the needle over the green. TCAS varies the red and green according to the perceived risk.

I must be getting confused with where I've seen it on glass cockpits then! Thanks for the extra clarification
