I don’t fly something that says “DECIDE”, the aircraft I’ve flown say “MINIMUMS MINIMUMS” when they get to the height set on the radio altimeter. In the end it doesn’t really matter what it says as long as it is unambiguous in context. It is merely a trigger, often a secondary trigger, for the pilots to do something.
In the outfit I fly for, a white “bug” is set to the decision altitude (typically around 200’ above the airfield) on the barometric altimeter and the radio altimeter is set to 150 feet which is always less than the decision altitude because we only do category 1 approaches.
During the approach, when we get to 100’ above the white bug, the non-flying pilot (PNF) calls “100 above”. The flying pilot (PF) checks that this is true and says “checked”. He/she also starts to glance outside more frequently in the hope of getting visual reference to the runway. At the white bug the PNF calls “minimum” and the PF looks out and if they can see the runway they say “visual” and they continue for a landing. If they can’t see the runway they say “nil sighting, going around” and commence the go-around procedure. Assuming they’ve called visual, shortly after at 150’ above the ground, the aeroplane will say “MINIMUMS MINIMUMS” and this is a last ditch cue for both pilots to confirm they are visual and it’s ok to continue for a landing. If they are still visual the PNF will say “visual” if they are not visual the PNF will say “go around”
This is the minimum babble required by the company and doesn’t preclude the pilot from calling “visual” at any point and discontinuing the instrument approach in favour of a visual approach or conversely deciding to go-around at any point if the required visual reference is lost or for various other reasons.
My point in all of this is that there is a rigid framework of procedures that pilots operate within (SOPs) and a lot of the procedural stuff involves expecting some kind of cue such as the other pilot or aeroplane saying or doing something and when that cue happens you do the appropriate action or say the appropriate words in response.
The aeroplane could say “PYJAMAS” at the decision height and, as long as that was what you were expecting it to say and you knew what that cue meant in terms of required actions from you, it wouldn’t make a difference.
There are pretty much just two arbitrary “decision points” in a flight. The decision to continue visually at the minimum altitude of an instrument approach, and, as Machine Elf says, the decision to continue the take-off at V1. The words at V1 are typically “vee one”, not “decide”. There are many other fuzzy decision points in a flight, the point at which you can no longer return to your departure airfield or enroute alternate and must commit to the destination for example, but there is only ever one time in a flight that you will hear “DECIDE”, or in our case “MINIMUMS”, so there is no possibility for confusion. We know what it will say, when it will say it, and what we must do in response.
To answer your question about whether they are industry wide standards, the answer is sort of but not really. There is some variation around what is said and who says it. There is also variation among manufacturers as to the words used by the aeroplane, but once in an airline a pilot will normally only fly one type for a number of years so they just learn the aeroplane’s quirks and adapt. They are all variations on a theme though, The aim of the game is the same and the methods are similar. Also if you stay with one aircraft manufacturer it is likely that the majority of the SOPs will be very similar if not identical.
