How to Spot
Military Aircraft

Before you drive to Wales at dawn: weekday timing, which apps actually show military traffic, and the difference between training sorties and airshows.

The short version

Low flying is almost always a weekday game. RAF and USAF tactical training runs Monday–Friday when weather and tasking allow. Weekends in the LFAs are usually empty.

Flightradar24 hides most military traffic. Use ADSB-Exchange or 360Radar to see whether Typhoons are already holding near you.

There is no timetable. Empty valleys happen. Training is not a show. Never drive toward an aircraft, flash cockpits, or use lasers.

Low Flying Areas (LFAs)

Britain has twenty Low Flying Areas where military aircraft may legally fly down to 250 feet (lower with special clearance). The spotter favourites:

Fence-line spotting at operational bases (Lakenheath, Coningsby, Marham, Lossiemouth) gives frequency without hillwalking.

Tracking apps

ADSB-Exchange — shows military Mode-S when aircraft transmit. Filter for Mil or search callsigns like RRR (Reach), ASCOT (RAF transport) or unit-specific codes.

360Radar — UK-focused aggregator popular with Mach Loop spotters. Good for checking whether anything is holding near LFA 7 before you leave home.

Flightradar24 — excellent for airliners; filters out much military traffic by design. Do not rely on it for low-flying sorties.

Etiquette

Field craft

Park legally. Stay on rights of way in National Parks. Keep dogs on leads. Never shine lasers or flash at cockpits. Do not fly drones near active airfields or display lines. This is operational training — not a paid airshow with a crowd line.

Common questions

Why does Flightradar24 not show military aircraft?

Many military aircraft operate with transponder settings that commercial aggregators filter out. ADSB-Exchange and 360Radar show more military traffic.

What days are best for UK low flying?

Weekdays, almost exclusively. Weekends and bank holidays are usually quiet in the LFAs.

How many Low Flying Areas are there?

Twenty across England, Wales and Scotland. LFA 7, 17 and 10 are the spotter favourites.
