English is the international language of the air, although a few minutes spent listening to an air traffic controller and you’d be forgiven for not realising it!

Over the decades aviation has collected a unique blend of specialist terminology and a dizzying array of acronyms.

But, it is a language that pilots and controllers all over the world will recognise, with the standardisation helping to ensure efficiency and above all, safety.

However, to the uninitiated it can seem as impenetrable as any foreign tongue. So we wanted to see how good you were at deciphering five phrases from Heathrow controller, Ady Dolan.

Leave a comment with what you think the ‘translation’ is to these common air instructions, not forgetting the bonus round at the bottom.

And no cheating!

1. “After departure, climb straight ahead London 2 DME”

2. “Cleared to New York Kennedy, Compton 3 Foxtrot departure, Squawk 6244, QNH 998 Hectopascals”

3. “Turn right on Bravo, Link 21 join Alpha, hold at MORRA”

4. “Follow the greens, Stand 544”

5. “Speedbird 472, LOC/DME approach, Runway 27 Left”

Bonus round

Most aircraft use the airline name as the start of its callsign, e.g. Air France 4421, Lufthansa 371, United 232. But some, like BA with Speedbird, have unusual alternatives.

Can you identify these airlines just from their callsigns?

This may or may not be a clue.

Whilst I might be able to make an educated guess at some of the answers, I really wanted to comment that I think this is an excellent use of this space and would welcome more of it. Well done Paul & Andy.

1. Once airbourne climb straight ahead until 2nm from LON VOR,

2. This is a departure clearance (NOT a takeoff clearance). The aircraft is cleared to JFK via the Compton 3 F SID. Their squawk code to put into the transponder is 6244 to identify them on radar and the air pressure at MSL is 998 hPa. The word hectopascal is only said when the QNH/QFE is lower than 1000.

3. These are taxi instructions. Turn right onto Bravo taxiway and use Link 21 to get to Alpha taxiway and then hold at holding point MORRA.

4. Green taxiway lights highlight the route that ATC have chosen to the aircrafts stand which in this case is 544. The aircraft is being instructed to follow these green taxiway centreline lights.

5. This BA aircraft is using the localiser DME to runway 27L. This will give lateral guidance to the aircraft but the pilots will have to use their distance measuring equipment to work out their descent rate and the altitude they will need to be at at certain distances from the airport which is printed on their approach charts.

1. After take off climb on runway heading to 2 nautical miles from the London distance measuring equipment.

2. Cleared on take off to follow standard “Compton3F” departure route. Destination is Kennedy New York. Squawk is transponder code to be entered and QNH is the pressure setting.

3. Is taxiing instructions while at the aerodrome. MORRA is a reporting point on the ground. Bravo and Alpha are taxiways. Link21 is probably a crossing.

4. No doubt at heathrow where planes follow green lights on the taxiways to their passenger gate.

5. Instructions from approach controller for a Localiser/distance measuring equipment approach into heathrow. Sort of like a talk down.

I’ll let someone else do the bonus round 😉

Is it ok to listen in to ATC IN THE UK?

Go on, I’ll have a go:

1 – After tako off, fly in a straight line for 2 miles
2 – Your ATC clearance is to follow the standard instrument departure route, transponder code 6244 and the atmospheric pressure above mean sea level is 998 hPa (or millibars)
3 – Taxi instructions: follow taxiways to holding point
4 – follow the green taxiway lights to your stand number
5 – British Airways 472, standard instrument landing system arrival on runway 27 left

Airlines are: Aer Lingus, South African Airways, US Airways, European Air Transport (DHL), China Airlines, Brussels Airlines, Middle East Airlines, Pan Am.

There’s no point rewriting what david said because I agree with his answers! Missing callsigns:
4. A franchised part of DHL but used in most European stuff as opposed to “World Express”
5. Air China
7. Middle Eastern Airlines (Logo is cedar tree)
8. Pan Am but not sure if its being reused by someone now…

1. Departure instructions, after takeoff, climb straight ahead to 2NM from the London VOR.

3. Taxi instructions, make a right turn on Bravo, use Link 21 to get to Alpha and then hold at MORRA.
4. Taxi instructions, follow the green taxi lights to stand 544.
5. Approach clearance, the British Airways flight 472 is going to approach runway 27L on the Localiser/DME approach.

I think BEA’s callsign Bealine was retained by BA after the merger with BOAC and is now used for ground towing movements at LHR

1. After take off climb straight a head (runway heading) until two miles from LON VOR.
2. This is a clearance to New York on the Compton 3 foxtrot standard instrument departure. Put 6244 into your transponder and have 889ha set on the altimeter as QNH.
3. Taxi instructions to turn right onto bravo taxiway. Continue via link 1 to alpha taxiway and stop at holing point MORRA.
4. Follow the green lights on the taxiway and they will bring you you your parking at stand 544.
5. British airways plane given instructions to do a localiser/distance measuring equipment approach to runway 27 left.

Great to see everone knows my airline’s call sign! 😉

We thought it was about time to put you out of your misery…

Thanks to everyone who took the time to comment – it was fun to read everyone’s submissions. If there are any other similar quizes you’d like us to run in the future, we’re always open to ideas.

Paul

1. “After departure, climb straight ahead London 2 DME”

This means, after take off, climb straight ahead until you are 2 nautical miles from the ‘LONDON’ Distance Measuring Equipment beacon.

2. “Cleared to New York Kennedy, Compton 3 Foxtrot departure, Squawk 6244, QNH 998 Hectopascals”

This means that you are cleared to JFK airport, routing via the Compton 3F Standard Instrument Departure. Your transponder code is 6244, and the atmospheric pressure at sea level is 998 Hectopascals (or millibars).

3. “Turn right on Bravo, Link 21 join Alpha, hold at MORRA”

This is a taxi instruction for an outbound aircraft. The aircraft must route along taxiway Bravo, then change to taxiway Alpha at Link 21. It must stop at when it gets to MORRA, which is a runway holding point.

4. “Follow the greens, Stand 544”

This is used when the Airfield Ground Lighting system is switched on, either at night or in poor visibility. In this instance, an inbound aircraft is given green taxiway centreline lights, controlled from the Visual Control Room (Tower) to its parking stand.

5. “Speedbird 472, LOC/DME approach, Runway 27 Left”

This is a transmission by an inbound aircraft. Speedbird is the callsign used by British Airways, and the aircraft is flying the approach using the Localiser signal (to maintain lateral position on final approach), and the DME (Distance Measuring Equipment which tells him how close he is to the runway).

Preuming on No 5, with a LOC/DME approach, that the Glidepath which provides glideslope guidance, is unserviceable on 27L otherwise it would be a normal ‘ILS Approach’?

Hi all,

Everyone in the tower has been very impressed with the quality of the entries, but the clear overall winner has to be David, although it was Andy Russell who was first to get all the callsigns right!

Congratulations to David and Andy and thanks to everyone for playing along – hope you enjoyed it.

Isn’t number 5 meant to be “BAW427, CLEARED loc/dme approach runway 27L, QNH xxxx” ?
