Height of 'airborne'

'When airborne, contact Departure...'
What height does it mean?

Safely Airborne ie Gear up, Flaps coming in and you have time to talk on the radio. So once you are happy that it will be safe to speak to atc as the acft comes clean

Wow! Is somewhere still using that dodgy procedure?

You'd be surprised and appalled at how many places do this. Didn't Birmingham try it for a while?

A lot of Europe uses the procedure of auto freq changes. Off hand I can think of TXL, BRU, AMS, CPH, CGN?, DUS?, FRA, STR. For some they require 'immediately after take off' (BRU, TXL) and for others on passing a certain altitude (CPH 1000', AMS 2000').

I don't have a real problem with it, personally.

Slightly more problematic are those that change frequency 'automatically', when it's not a published procedure!

At Bourget there is a board at the hold telling you to turn immediately after take-off and contact departures.

The best indication that you are expected to change automatically is when you hear "G-CD Clear Take-off. Good-bye"

Yesterday I departed Muenster having been talking to Ground for taxi. I got one line from the tower. "G-XXXX Good Afternoon, wind xxx, xx, cleared for takeoff runway 25, Goodbye".

Another non-standard phrase which has been said to me is "advise when leaving the frequency". I find this quite useful airports which are not that busy and an expeditious transfer to approach or the area centre is not required. It also reduces r/t when the flightdeck workload is quite high. However I like to transfer to the next freq. quickely to stop any problems arising.

Im a 'controller under training' and the discussion of " when ready contact Rader on xxx.xx" came into play. As it had before.

In the instance today unfortunately an early stop off level was required due to an overflight at 3.5A ( transition alt in the zone is 4A) therefore, dep stopped at 2.5A ( yeah we had seperation and everything!!!)

I can understand why you would want the pilot to go straight to the radar frequency, lets get the guy clear of the traffic and into a continuus climb asap, no one wants a jet stopping off at 2500 and flying directly over their house! - I personally do not like to speak to a pilot when they are cleaning up etc and im sure they wouldn't appreciate it either.

In another instance, bad weather off the end of the runway, Pilot says requesting heading of blah after departure to roll, check with radar and they approve, would it not be useful to get the pilot to contact radar when airbourne so that if the weather moves (as it does sometimes!) that the pilot can tie it up with someone who has the complete traffic scenario rather than me passing messages?

Just a thought

Turn It Off

"When ready contact radar on xxx.xx" seems like a useful phrase at first, but since whenever most pilots are given a frequency they dial it straight into the box, it is a little redundant. You might as well use the standard phraseology, "Contact X on xxx.xx". If the pilot is too busy he will tell you to standby or he will change frequency but not check in until the workload allows.

If you think you might want to transfer the aircraft quickly from Seaton TWR to Medway ACC, either for your own benefit or for wx avoiding, the best way to ensure a quick change is to do as LL do and use the phrase "departure frequency when instructed xxx.xx". This works well if the next frequency will not be known to the pilot (eg SVFR, LL dir instead of TC etc) and could perhaps find use at PF and PH where we have no idea who we are going to call next to explain why we are flying towards the rising hills carrying out an emergency turn!!

You must fly to some pretty laid back places!

All the best

We dont even start (757) to bring the flaps in to 3000 feet AGL which is way to late to start talking at most places. It tends to be Gear selcted up push the button on the flip flop to change freq.
The thing to watch for is people changing to departure once cleared take off and still sat at the end on the runway.

... whereas we (757) start the flap retraction at 1000'agl, which is way too soon to start talking to anyone. (This is why at places where the silent handover is supposed to occur immediately after take-off eg EBBR, EHAM, EDDF etc. we don't normally check in until FLAP UP has been selected).

Just goes to show there is more than one way to skin a cat!!

AUTOMATIC CHANGES?

Can someone please explain to me how automatic radio changes work?

I am a mil controller, and have noted a few occasions recently that ac have changed sectors (or even FIRs) without contacting the next agency. On at least one occasion, this was put down to a failure of the 'automatic frequency selection system' or some such. The chap I spoke to didn't have great English, so I was reluctant to ask for more details.

Much obliged.
