Doubts About The Gannett AEW.3's Electronics Suite

WELL DONE AGAIN!!!! THANK YOU SO MUCH!!! 😉 🙂

Air Publication 101-2803-1B
Gannet Aew Mk3 Aircraft

Chapter 2 Radar installation

The A.R.I.5885 is a navigational equipment operating on the Doppler principle,which measures:
(1) Ground speed over a range of 60 to 800knots,and
(2) Drift angle from 0 to 30 degrees port & starboard,
at altitudes between 200 & 60,000ft .
The information is presented on an indicator in the crew cabin on the forward
top decking ,port side.

For what A.R.I.5885 stands for? A radio? A navigation device? Can you tell me about it?;)

WELL DONE !!!! Can you tell me the page number these data were extracted from? I am an aviation researcher from Brazil with some published articles (here you can see one of them: http://www.laahs.com/artman/publish/article_220.shtml) and I am working on a book about all AEW/AWACS platforms ever built. So, I would like to obtain the page from were the above data were extracted, in order to cite it on the notes. But, again: WELL DONE!!!!

Basic list from the Gannet AEW 3 manual.

AN/APX-7
A.R.I.5848 F-4 I.F.F. MK.10
A.R.I.23134/3 I.F.F MK.10
A.R.I.1807/1 TACAN
A.R.I.5885
AN/APS-20F
AN/ART-28

I’ve added more detail to the above post.

I haven’t seen info published like that anywhere, there are available pictures of the interior of the radar operators position. I haven’t seen the 4+ books but the two Gannet books I have don’t list this info.
I’m surprised in retrospect that I never bothered finding this info out myself.
It must be fairly obtainable information though.
The other thread gave some details, are these not enough or do you think they are incorrect?

Well, following the 4+ books style on the another aircraft, this kind of info should be on the volume about the Gannet. I thank you for the info you posted in the another thread, but I think it not enough, despite you did all you could on the subject;) . I emailed to Westland right now, let’s wait some results…:)

This is what I know,
The main AEW search radar was definately AN/APS-20F feeding two standard scopes and included IFF interogator, data link to the ground ship) was via AN/ART-28 Bellhop. The aircrafts movement was compensated for by using links with the internal Doppler navigation kit and by calculating ground speed and drift.
Obviously other communications and ECM devices were fitted, and one even had ‘Orange Harvest’.

I know you answered already, but I was hopeful in obtain such a list of the avionics aboard the Gannet. I will try to contact the Westland Helicopters as you suggested. The info I am looking for may be in the 4+ Series volume on the Gannet. I have tried to find or download the above mentioned book, but I did not get. Do you have this book? Could you tell me if the info I wish is in it?
If so, is there some way to tell me the data, as well as the page where it is?
THANK YOU SO MUCH FOR ALL ATTENTION YOU HAVE PAID! 😉

I thought this was answered for you in another thread, is it the AN APS 20 radar you need more info on, or the operators consols?
Westland became the Gannet design authority when they inherited Fairey Aviation in the early 1960s, and did most of the subsequent rebuild and mods. etc.
Try contacted Westland Helicopters’ Public Relations Officer at Yeovil, Somerset, he was very helpfull for my Gannet research about 16 years ago, dare say it will be someone else now, but worth a try.
If you draw a blank I know an ex Gannet scopey, he might have some less technical info.
