Introduction to the Mach Loop

The Mach Loop is a set of valleys, situated between Dolgellau in the north, and Machynlleth in the south (and from which the Mach Loop gets its name), which are regularly used for low level flight training, with flying as low as 250 feet (76 metres) from the nearest terrain.

To the south of the Mach Loop there is an area called Tactical Training Area 7T, in which, at specified times, the aircraft may fly as low as 100 feet (30.5 Metres). The Royal Air Force publish a timetable of when the Tactical Training Areas may be in use, however experience shows this to be of little use in determining whether low level flying will take place on a particular day or time.

Low flying is an vital skill for military aircrew, and the Royal Air Force uses various areas of the United Kingdom for low level flight training. The United Kingdom is split into 18 low flying areas, (or “LFAs”), the LFA’s being numbered 1-19 (strangley there is no LFA15). The Ministry of Defence website has a map showing the location of the low fly areas. The Mach Loop is located within LFA7, which covers the whole of Wales, except for a small section in the north-east of Powys, which is within LFA9.

Cad West & Cad East

Cad West, in the Mach Loop, is a great location if you want a ‘topside’ or ‘level-pass’ view of aircraft. You also get a decent amount of time to prepare following the initial shout of “incoming!”, as the aircraft approach from your left. If you are lucky, they will sometimes take a left in to Corris Corner, potentially giving you the opportunity for a second pass. There is plenty of room for parking, with a steadily advancing climb as you make your way up the hillside.
