RAF aircraft used Smiths Attitude/Heading Reference system?

OK, so in the VC10 the system controlled compass AND attitude indicator? The photograph in #10 on top is
acutally from the Hawk's flight manual. Good to know, that there are more birds out there using the same
sestem as it increases the chance that there survived some information and/or material!

From when do you remember this panel?

Just checked the WEB but have not been able to spot the panel in any of the pictures
there (not cockpit and not tech station): a b

The compass controllers were fitted at the navigator's position - your photos show the pilots' position.

Attitude was not derived from the same system.

The VC10K had a completely different compass system.

Thanks BEagle for the information. Here WEB page dedicated to the VC-10, but
unfortunately the cockpit photos there (nav/tech) do not show the panel - so probably
it is the wrong type. There is a flight manual out there showing the panel, but it
is different from panel shown in posting 10 (top) - and it is named "compass". So
you are right, that it controlled just the compass and was a heading reference only
in the VC-10.

Thanks for responding...

Memory of the seventies is a bit faded, but I have definitely worked with that panel somewhere before. Belfast? B707?
Can't be sure which aircraft but it certainly wasn't a Hawk.

Meanwhile I obtained a picture of the panel from the VC-10 (Thanks a lot to Terry!) - it looks
quite different from the Hawk's panel and is marked as "COMP":



Of course some of the controls are similar, but there is a different system behind
the scenes I think...

As there was some time during the lock-down I had a look at an attitude indicator NDN6714-03, ref. no. 6370014, made by Louis Newmark, to see whether it might fit the test set....


...but after some measurements I am sure, that this indicator is remotely driven by gyro signals, but it does not match the test set as it seems to be more modern - plugs do not match and are next generation MIL plugs compared to the ones on the test set. So unfortunately the search will go on and the indicator in the Hawk even looks different:


So the following questions to the Hawk experts: In the lower middle we see the control panel of the compass reference system (red arrow). We also see the attitude indicator (blue arrow) looking different than the one I investigated. Which instruments (yellow questionmarks) are also controlled by the AHRS, probably direction indicator left one, but also the HSI?
