Der Mensch said:Hello Everyone,
I have often wondered how the engines on multi-engine planes are numbered. I have heard many versions on how they are numbered. Examples of a four-engine plane: 1.) 12|34 2.) 31|24 3.) 41|23 and the list goes on. Can someone clarify for good what the real numbering is?
Der Mensch said:No what I meant by the 31|24 (or others) is that the engines were numbered left to right 3 1 2 4 with the | representing the fusalage.

Engines are always numbered 1,2,3,4 left to right, sitting in the pilots seat (the left seat). Now the starting sequence on a specific aircraft may reflect what your looking for. Depending on the aircraft sometimes #2 was started first because it carried a generator or air power unit that were used to start the other engines. In other cases it might of been an engine that housed a hydraulic pump in its accessory section with that pump being needed to work a piece of equipment. Sometimes 2 and 3 were started first and as the aircraft were taxing 1 and 4 were started. Hope this answers your question...

Are you sure this is true for all nations? Also, are you sure it was always the case?
DerAdlerIstGelandet said:This is sort of off topic and I can not say it is true for all nations or for all aircraft but just an example is my Blackhawk the number the 1 engine is on the left side and the number 2 engine is on the right side.
Oh ok, I'm backwards, its from working on helicopters!DerAdlerIstGelandet said:No I was actually agreeing with you. You said engines were numbered 1,2,3,4... from left to right. My number 1 is on the left my number 2 is on the right.
