The Mach Loop (also known as LFA7), is a series of valleys in West-Central Wales which are often used by the Air Force to train on low-level (as low as 76 meters (250 feet)). These locations are strictly private properties and we would like to point out the fact that you are strictly responsible for every actions that you will attempt up there and may occur some issues with locals/police/farmers etc. this is why we are recommending to follow carefully our advices. In the following we will list some websites which we found very helpful, especially if you are at LFA7 for the first time:

1. Rough flight plans reagrding hours of duty for the next weeks(this is no timetable for the LFA 7 and not shows the traffic for it!)
2. The most used flight routes and moves
3. Accurate weather forecasts for this special region

Aircraft most seen in the area includes:

UK Royal Air Force : Airbus A400M / Texan / Hawk / C130 / Beechcraft / Chinook / Puma / Apache / Typhoon / F35

United States Air Force : F15 / F35 / MC130 / V22 Osprey

However, since a Typhon was involved in an incident in October 2018 here, LFA7 activity was reduced. On average you will see 2-5 movements a day now during “good weather” (clouds or sun), but sometimes there are even days with 0 or also 20 movements (even if there is good weather). Depends a lot on your amount of luck! Furthermore this place becomes crowdy during good weather and UK holidays.

Security	There are no problems with the military, police or security services normally. However, you should always be at secured points only and don’t risk steep spots and ways at cliffes and edges. Take care when climbing and rather wear stable hiking shoes! Also if you camp in a tent up the hill, choose a safe spot and secure everything well as it can be windy!

You can find a parking by the roadside of A470 again and then take the paved footpath up the hill. However, after a few steps you have to decide whether you go to lower or upper Bwlch. Option a – lower Bwlch: Turn to the left at the first y-junction and you will get to a nice position for side-side shots after a steep 60 vertical meters Option b – upper Bwlch: Keep to the right at the first y-junction and make the long way all up the steep hill  for approximate 45 minutes to 1 hour (120 vertical meters) as marked to have an elevated view onto the fly-bys.

FOCAL LENGTH	100-600mm recommended Hercules = 310mm; A400M: 180mm, F-15: 400m. For the Texan and Hawks you will need up to 600mm as they are really small.

	Spot #3 – CAD East
WHERE	CAD East can be found east of the narrow valley where the aircraft fly thru. Park your car at the offical parking. On the opposite side you will see a ladder to climb over the fence to get on the path. Take the ~1,5km  and 120 vertcial meters footpath as marked on the map up the hill. A part will be on a asphalted road which is the same way if drive up by car (see next part). Once you reached the small car park just walk along the trees to the plateau which offers a fantastic view. It is exactly on the opposite side of the offical parking. If you don`t wanna walk you can also drive up to the location on a asphalted road. You can reach this road next to a farm (Stabal Holiday Cottage on google maps). Open the gate (and close it!) and drive up to the top (several gates will follow) until you see a small parking for a handful of car to your left, next to the beginning of a forest.
