maarten4, there are no silly questions, omly silly answers. I hope that this is not one of them
I'm a little unsure of your question "
how is it called as to whether you are looking for the term for an engine failure at/above V1, or what does the support (non-flying pilot) call?
The terminology is a bit loose, but it is typically referred to as an engine failure ON Takeoff (as opposed to the more typical single engined aircraft AFATO, engine failure AFTER Takeoff).
A bit pedantic, but the subtle difference in terminology lies in the fact that for an engine failure at or just above V1, there is often still quite a bit of the Takeoff remaining, i.e. acceleration to Vr, Rotation, Initial climb to the (typical) 35 ft screen height at the end of the runway, with acceleration to V2 accomplished in this final phase.
Calls made by the Pilot Monitoring (PM), or PNF not so far back, vary greatly according to the airline's SOPs. Some call it, some don't call it at all, the latter because the Pilot Flying is ACUTELY aware that he/she has suffered an engine failure.
I tend to prefer the initial "silent" approach. During the Takeoff roll prior to V1 the PF is "keyed up" to hear the word "failure" and would reject the takeoff without any attempt at trouble-shooting upon hearing the word "failure" (stated very assertively). NUMEROUS Simulator exercises have shown that although the PF may well have heard the V1 call, many (far too many) are still "keyed up" to hear the word "failure", and attempt to reject above V1 if "engine failure" is called soon after V1.
Our experience has shown that it is best to let the PF continue the Takeoff, and AFTER the gear is up and the aircraft is climbing away at V2, the PM would announce
in a much lower tone of voice his/her first analysis with a statement such as "Right engine has failed, no apparent damage", etc.
Subsequent procedures will be of the nature of the PF confirming (or denying) the PM's analysis, and all non-normal procedures thereafter executed after confirmation by both crew members.
Other operator's SOPs
WILL vary, that's how we do it. I recognise that for a 3 engined aircraft, failure of the centre engine would warrant an "engine failure" call, as there are no directional control problems experienced by the PF, and the call would confirm to the PF that the performance degradation was not caused by other factors, e.g. wind shear.
Standing by to hear a great many SOPs (all of which are the
ONLY SOPs.
