Agreed; And when the potential becomes a reality the call should be issued.ahramin wrote:I'll admit it was a bit of a trick question. While none of those situations necessarily require a Mayday, each has the potential to be a Mayday in certain circumstances.
Agreed; However, not every emergency is a MAYDAY. PAN PAN is there for a reason and should be used when appropriate.The point is that if we continue to equate Mayday with panic, you remove that option whether it's needed or not.
Is that IAW with CARs or just your company SOPs?And yes, a rejected takeoff in a heavy is a mandatory Mayday,
I don't see MAYDAY as being the wisest way to bring everybody's SA up to speed in that situation. I hear MAYDAY and the automatic assumption in my mind is that someone is in the air who needs to get on the ground in a hurry. I would suggest that a better call in that situation would be along the lines of "XXX Aborting on runway XXX". Granted, there seems to be no ICAO standard for this, (However, the term 'stopping' does seem to pop up in ICAO standard phraseology.)In low vis conditions you will also use Mayday regardless because there may be an aircraft landing or taking off behind you.
Yep, they do and there is a long list. If you dig a little deeper I'll bet you find that the radio call they made was a PAN PAN.CFR wrote:DND considers a single engine shut down in a C-130 an "emergency". Search CADORS for a long list.
A MAYDAY call is nothing to be afraid of and does not mean panic, (panic and flying never mix well). It just indicates that your circumstances are dire, that there is a grave and imminent threat requiring immediate assistance; I.e. circumstances have developed which require you to get on the ground immediately.
A PAN PAN call is also nothing of which to be afraid. It does not mean panic, it just indicates that you have a problem, but you can keep the machine safely in the air for the time being.
Use the calls when you need them, but use them properly.
