Hiya, Maltby 'ere.
Sorry I've not been in a forum mood recently. All FS time is going into the FSDS3 1-11 models, which have been taking an annoyingly long time to complete. :huf:
Since there will soon be a new FSDS3 1-11 (complete with ACME backlit gauges) I will have a look at including a mod to the panel for this too.
I'd never noticed there was a possible inaccuracy, but am quite happy that the 1-11 wants changing. I'll side with Tonks on the VC10 though.
From having a quick look around the net I'll go for an ILS range between 108.10 MHz and 111.95 MHz, unless anyone wants to change my mind. It should be easy enough to put into the code.
I also thought there was some similar issue dealt with on the Trident model but can't find any evidence of it now. Maybe it was all that business with stopping the RMI gauge from showing ILS signals ?? Can't remember now.
If I was a pilot I wouldn't have a problem with the GS flag showing any time there wasn't a GS signal. It seems to make good sense on the 1-11 units because it physically hides the GS pointer.
I can't see why it's better to uncover the GS pointer when it's not actually working, but if that's what it has to do, so be it.
Or should the GS pointer hide as well if it's not tuned to an ILS frequency?
Am I right in thinking that the units in the 1-11 are an American design? Maybe that's why the VC10 is different.

Hiya Dave
Agree on the flags too. It sort of makes it obvious to see flags in place doesn't it.
Yup.. it was the RMI issue on the Trident.
And finally.. yup.. the units in the 'standard' (non BA) 1-11's are Collins units which originate (I believe) from t'other side of the pond Units fitted in the VC10's were Smith's.. even in the K3/4's (Smith's Military) me thinks

Hi Leif,
There may be a lot of truth in that mate. BAC were keen on selling to the US and standard fitment of US instruments would certainly have helped. I love the look and operation of the Collins F-D 108 (which is the total package.. HDI/HSI/Flight Director/RMI e t c) though like DM, would have been happy for it to operate as DM programmed it.
I now wonder if the system fitted in the CS707 also clears when an 'off' freq is selected?? :think:

Hiya Garry,
It's difficult to pull any two shots of a 1-11 panel that are the same and that goes for the ex-BA panels too. However, all the shots I've ever seen of the 1-11 flightdeck show the ex-BA aircraft to be similar (for well documented reasons) and the rest are a variation on a theme. That is, all non-exBA flightdecks looked resonably similar and the rest were exBA
The 1-11 broke new ground in that it was never designed to be 'airline specific' and it is perhaps because of this.. the desire to appeal to the widest possible market, that the use of the best 'common' instrumentation available was used. BA probably had the best idea in the end as the UK fleets, though similar, were different enough that it was not possible for pilots to cross-fly 200/300/400/500 series aircraft. Even that is open to debate though as when BA swallowed up other airlines fleets, they inadvertantly introduced this very problem.

Hi Dave
Thanks for that. It does seem that there are differences but that is not a deliberate manufacture thing.
BA or really BEA were different in any case having the flight decks fitted out to be as near as poss with the Trident so I suppose the 510 can be ignored. The panel on those look like there is something missing
Even thought I do see some variation due to model type or age there does seem to be a similar look unlike the Viscount were it is often difficult to find two marks that look anythng like each other.
I suppose though in the reality of FS even the most standard of aircraft will have some differences so there is always going to be someone who use to fly of know them well will find not everthing is as they expect.
I always had the impression with the One-Eleven that maybe the type or make of instrument would vary to perhaps an American version but the layout does seem to have been kept so at least you know were to find it.
Of course with an aeroplane that flew for as long as a One-Eleven there will have been evoloution differences to aircraft that may well have been identical on the line but then spent twenty five years on opposite sides of the globe.
