cancelling an emergency
On ATC recordings worldwide, I've heard a few people cancel an emergency after engine failure or fire is contained and inform that a normal landing will be performed, is this a known or correct practice?

Obviously it's a known practice, as you know about it. ;)
There are no "rules" saying a pilot can't do so, if they consider that a safe course of action. There are a couple of types of emergency call for a reason, though - Call "MAYDAY" when you have a problem, need priority in the air (and/or navigation assistance) AND you suspect an unsafe emergency landing could result - this helps the ARFF commander to decide if they need to decalre a full emergency response (i.e. notify hospitals, ambulance services etc etc) Call "PAN" when you have a problem, need priority in the air (and/or navigation assistance) BUT once, you are at the airport you expect a safe landing to be made (e.g. - a medical incident on board etc) It would be quite normal to decalre a MADAY for an engine fire, and downgrade to a PAN once you are sure the fire is out. In any case, the airport emergency response will be decided by the ARFF commander - they would probably stay on local emergency standby for the landing even if the pilot had "cancelled the emergency". |
Engine failure is a PAN call except I think for twins it's MAYDAY in Japan. Fire is a MAY DAY but once everything is under control should be down graded to PAN.

RTF Emergency Communications
As soon as there is any doubt as to the safe conduct of a flight, immediately request assistance from ATC. Flight crews should declare the situation early; it can always be cancelled. Source |
Thanks for the comments,
I've always been taught that declaring an emergency guarantees you a clear runway, downgrading to a non emergency to me feels like you're waisting that resource which was already in play. I'd cancel an emergency, after an emergency descent when everything is ok for instance, that makes sense. on the MD80 they used to tell us, if you only have one left of something, you are on an emergency |
Can fly with 1 Pack for 10 days etc.

The point is proper phraseology should be used at the appropriate times and therefore many airlines tend to standardise it in order to avoid any possible confusion from flight crew should the need arise. Your OM(A) Chap. 8 might have some guidelines for situations warranting the declaration of a mayday or a pan call, and that is basically how your operator wants you to deal with that particular problem. I have seen operators where, on a twin, the inability of an engine to deliver up to full unrated go around thrust was considered an engine failure and warranting a mayday call (even with an engine running just a bit less than normal cruise thrust and the other normal) or running on a single engine driven gen, and other airlines where a V1 cut with no fire is a pan call and so on. It is not always black and white.

May I be pedantic here? The call is actually pan-pan, not pan!
Sorry, but I do like correct phraseology on VHF. Pan-pan, pan-pan has very different and recognizable rhythm compared to pan! pan! pan! |
Where have You read on this thread that the call to atc is "Pan" ? And by the way it is pan-pan repeated 3 times, not 2. Not to be pedantic obviously.

Call "PAN" when you have a problem, need priority in the air[/quote]
Also in several recordings that I cannot put my hands on now. |
For the UK :
CAP 413 Radiotelephony Manual Edition 22 Chapter 8 Emergency Phraseology Distress and Urgency Communication Procedures .........the RTF procedures which should be used by civil pilots under the Aeronautical Mobile Service during an emergency in the UK. Additional information is published in the UK AIP (GEN) section and AICs. States of Emergency 8.2 The states of emergency are classified as follows: 1. Distress A condition of being threatened by serious and/or imminent danger and of requiring immediate assistance. 2. Urgency A condition concerning the safety of an aircraft or other vehicle, or of some person on board or within sight, but does not require immediate assistance. 8.3 The pilot should start the emergency call with the appropriate international RTF prefix as follows: 1. Distress ‘MAYDAY, MAYDAY, MAYDAY’ 2. Urgency ‘PAN PAN, PAN PAN, PAN PAN’ |
I meant it as a generic name for the call - not instructions on how to call it. :)
I've always been taught that declaring an emergency guarantees you a clear runway, I have heard military pilots mention this - perhaps on a military runway, with its lower traffic, that might happen - but not in the busy civilian world. |
With an engine failure on a twin, are you really going to get treated any differently by calling a Mayday rather than a Pan?
|
There's a lot to do with States Rules and Procedures as well. When You audit different CAA's and local airport procedures things can change dramatically, obviously always (almost:oh:) towards the most restrictive procedure.

If it's not Your lucky day somebody might call a mayday after your pan :8

The causes of the crash—according to the preliminary report—were insufficient flight planning (disregarding necessary fuel stops), not declaring an emergency when the fuel neared exhaustion,[6] and another aircraft emergency at Medellín being given priority to land by air traffic control.[7][8][9] |
In my ATC days (quite a few years back but still vivid in the memory) I was taught, practiced and taught: acknowledge the cancel call but leave the emergency services on standby until a safe landing.
The slowest response for an emergency vehicle is when it is being reversed back into the shed. |
