Five Screens Before Take-Off: The UK Airspace Check That Beats a Hunch

Every UK drone guide ends with the same three words: check before you fly. Good advice, and close to useless in practice, because nobody ever says what a check actually looks like. A check is not a feeling you get while standing in a lay-by squinting at the sky. It is a sequence of screens you look at, in the same order, every time, followed by a decision you write down.

This is the five-screen routine we run before commercial flights in the UK. It takes about five minutes with a decent signal, ten with a bad one, and it has saved us more wasted mornings than any piece of kit we own.

Why a hunch is not a check

Most of the near-misses we hear about aren't reckless pilots. They're careful people who did check — a quick look at a map app, a glance at the forecast — and missed one layer. The map showed green, so they stopped looking. Nobody opened the NOTAM briefing. Nobody clocked the prison two fields over or the display practice starting at noon.

The fix isn't more paranoia. It's a fixed order: same five screens, same thresholds, same folder of screenshots. When something feels off, you want to be able to say precisely what you looked at and when.

Screen one: the airspace map

Start with a map that shows aerodromes, not just controlled airspace. In the UK that means the CAA's airspace guidance plus a live app such as Drone Assist, which layers flight restriction zones, ground hazards and airspace classes over satellite imagery.

What you're hunting for:

• Any protected aerodrome within 5 km. Inside a flight restriction zone you need permission from the aerodrome operator, and that applies to every drone, sub-250g models included.
• Controlled airspace boundaries — Class D and above — and how much usable ceiling you actually have before you're in it.
• Danger areas and military training areas, which have a habit of going active exactly when the weather turns nice.

Note distances to the nearest edge as numbers. 'About a mile away' isn't something you can plan a flight around.

Screen two: the NOTAM briefing

This is the screen most people skip, and the one that catches working pilots. NOTAMs cover the stuff that changes daily: temporary restricted airspace for air displays, major events, royal movements, big sporting fixtures, survey flights and infrastructure work.

Pull the briefing from the NATS AIS service, or read the same data in Drone Assist. Then read the times properly. UK NOTAMs are issued in UTC, which sits an hour behind your watch in summer and matches it in winter. Mixing the two up is how a pilot ends up inside a display box at 13:00 local, convinced they had another hour.

Write the start and end of anything relevant in local time on your phone before you get in the car.

Screen three: the ground beneath you

Airspace tells you whether you may fly. The ground tells you whether you should. Drop into satellite and street view and look for what never appears on an aviation chart: a primary school with a summer fete, a National Trust car park that fills by nine, a wedding venue with a marquee going up, a substation, a busy ridge path.

Two UK specifics worth knowing by heart. The Royal Parks have their own byelaws banning drone use on their land, and plenty of National Trust and Wildlife Trust sites take the same line. Neither shows up as a red circle in an airspace app.

Screen four: weather with actual numbers

Not 'looks alright'. Numbers, compared against limits you fixed in advance. For our main imaging rig that means gusts under 20 mph at flying height, visibility good enough to keep the aircraft in sight unaided, no active precipitation, and temperatures comfortably inside the battery's happy range.

Check wind at height, not just at ground level. A Met Office forecast for the village can say 9 mph while the exposed ridge you're launching from is seeing double that. Use the Met Office for the trustworthy local picture and a wind-profile tool for the altitude numbers, then believe the more pessimistic of the two.

Screen five: screenshots and the log

Before you leave the car, capture the map, the NOTAM screen and the forecast. Name the folder with the date and site. Then add a row to a spreadsheet with five columns: date, location, airspace notes, weather, decision.

This isn't paperwork for its own sake. If an image is ever questioned, or a flight is ever reviewed, a timestamped screenshot of what the airspace looked like at launch is worth far more than anyone's recollection.

The go/no-go card

Pin your own limits somewhere you'll see them. Ours, in short: any unpermissioned restriction over the site is an automatic no — permission in writing or no flight. Gusts above the aircraft's comfortable limit for the whole window is a no. No continuous line of sight to the planned flight path is a no.

Everything else is a judgement call, and judgement gets much easier once the first three screens have cleared the obvious.

Five minutes, then fly

The whole routine fits inside a coffee in a lay-by. It won't make you a better pilot. It will stop you being the pilot who drove two hours to a field they were never legally allowed to launch in — which, judging by the questions we get, is a far more common way to lose a morning than a flat battery.
