Is it just me or are the DL 76s prone to engine problems in recent times? Seem to have heard of quite a few issues lately with them.

Nicely shot and edited. Roughly 22 minutes elapsed time between the engine letting go and coming to a halt on the runway.

Great vid - love the old 76' climb capability on one engine.

All handled very well, apart from the (initial) non-standard r/t from Delta

So even outside of the US, American pilots are reluctant to utter the word "Mayday"?

It was not the procedure for decades and to give this crew credit they didn’t get the chance, they were contacted by the tower before being able to make that call

They did a good job

You have misheard the r/t. Listen to it again and Delta refers to themselves as "emergency aircraft".

It would be interesting to know what phaseology they use when practising emergencies in the simulator.

I was chastised on my last AQP ride for saying "Mayday."

ICAO RT is waaaaay down on the list of priorities in 'Merica.

We are now beaten with a wet towel anytime we say anything but Mayday x3 in the sIm.


The times of :
Uh….mumble….declaring…mumble…’murhency….mumble…*profanities*


….are supposed to be over.

We all know that the US of A have their own anything-goes phraseology which, I guess, is fine if you're flying domestically in that country. However, it might not be a bad idea for crews flying internationally to abide by ICAO standards when operating outside of the USA.

We were taught eng fail is not a May Day call, simply ‘we are declaring an emergency’ or ‘pan pan’ (which some controllers don’t seem to understand)

The point of having a pilot in the flight deck is that human judgement in the actual situation is better than any preconceived management idea or that taught in training.

Mayday is the international standard; a good starting point which can either be downgraded, or added to with additional information.

There is no standard engine failure, nor standard classification at the time of the event.

A 'Mayday' is entirely appropriate anywhere in the world when losing 50% or more of your powerplant.

Pilots flying internationally should not have to tailor their R/T to suit local customs. The US does not adhere to ICAO standards on many things because, quite simply, it was 'not invented here'.

According to https://publicapps.caa.co.uk/docs/33...026Nov2020.pdf
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’ UHF and VHF Emergency Service 8.4 The UK Distress and Diversion (D&D) Section is located at the London Control Centre. It is manned by RAF control staff who are assisted in the provision of an emergency service on the International Aeronautical Emergency Frequency 121.5 MHz and on 243.0 MHz by suitably equipped civil and military units and certain HM Coastguard stations. The service is available continuously to pilots flying within UK airspace who are in distress, in urgent need of assistance, or experiencing difficulties (i.e. temporarily unsure of position) which could lead to a state of emergency. The service may also be available for practices

Reassuring to know so many armchairs and MS sims are flown with the correct verbiage.
Well done DL crew.

"appropriate"?
I disagree.

It is mandatory.

Trust PPRuNe to get so excited over minutia such as phraseology which isn't standard where that crew come from during one of the more critical experiences the guys will face in their careers. They were also slightly rushed into the R/T by the transfer to radar pretty much at the moment the thing blew an engine.

They've had an engine fail at a critical phase of flight (and not your standard simulator V1 cut at that) and as far as I can see externally have flown the aircraft well (cue someone pointing out the slight downwind drift ) and made the appropriate decision to return expeditiously - they got the exact same response and service they've have got if they said the standard Mayday x 3 call.

Good job to them I say. Especially given it's Delta, so probably all done with quite the hangover.
