above is a document that contains a set of Ministry of Civil Aviation black and white slides about the Instrument Landing System in its early days. Also from the MoCA is another set describing the navaids and communications needed to support airways operations.
ECN0 from Dave Smith who says “I’ve just found this 1944 Ballykelly BABS assisted approach procedure chart amongst my stuff. The original was in a photo sent to me in the 1980s by a former Liberator pilot who flew from there.”
Blind landing May 1947 This remarkable article in Flight describes efforts in 1947 to develop a better visual instrument to assist pilots in interpreting the output from a beacon approach system which in 1947 would have presumably been Rebecca/Eureka or BABS (see above). Within the technological limitations of 1947 the author is developing proposals that verge on the use of virtual reality and head up displays. The Air Ministry had already trialled a system for projecting a night fighter’s air interception radar display onto the pilots windscreen.
Malcolm Hemming has sent me a document entitled ” Telecommunications equipment and its maintenance” which seem to serve as an introduction to this section. Tels Mx 
a rather grand but no longer anonymous microwave tower thanks to Danny Glover who says “ECN1 is the Post Office/BT site at Harraby, Carlisle – see this link. This mainly carried television and telephony but there is an ATC link – in the literal sense. The Linesman radar at Bishops Court used a microwave link via the Post Office site at Ballygomartin, then over the existing route to Carlisle. From there it’s not known whether it continued via Manchester and Birmingham or went across to join those from the east coast sites on their way to West Drayton. Most of the details of the Linesman (Post Office) and Mediator (CAA) microwave links have been pieced together – I’ll share more information when I get it properly organised.”
this might be something called the MCVFT at Croydon (or it might not).

Rhu Stafnesh – was this associated with the flying boat station at Rhu near Helensborough?
Rhu Staffnish (I think that is how you spell it). It is on the Mull of Kintyre, near Campbeltown, nothing to do with the Rhu seaplane experimental station which is on the Clyde near Helensburgh. Dave Lacey

Winstone radio station closure
The last CAA HF service being switched off at Winstone radio station by Jack Jewitt the longest serving member of the staff at the station. Jack, a rigger, went to Birdlip/Winstone in 1946 and said he’d give the job a try for a week to see how it went
The last service message being composed and sent to Portugal from the control room at Winstone.
Left to right Godfrey Elmer – Officer I/C Winstone, Bob Morris ATE II at Winstone, Reg Baker – later at LATCC but who sent the first message on the circuit many years ago.

below: the ubiquitous ministry workdesk
These desks in a variety of designs were built to equip state ATS units in the 40s, 50s and 60s, Many examples will be seen in photographs of towers, ops rooms and equipment rooms throughout this site. They were of a modular design, standard heights, widths, slopes and depths were introduced as were standard equipment stowage bays, usually 6 inches high and multiples of 3 inches wide. Horizontal work surfaces were removable and replaceable with, for example flight progress strip bays. Some “necessary” design features seem so dated now, with built in recesses holding cast metal cigarette ash trays. Remarkably by modern (2015) standards the desks were made of solid oak, light coloured and attractive and if they got scruffy they could be sanded down and re-varnished. Moreover the modular design meant that when a unit closed they could be refurbished and reused. I remember seeing a control desk in the NATS stores at Hurn that had a label showing it was formerly used at Preston ATCC at Barton Hall.
