| Engine Numbering
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?

I've never heard any other way an I worked on multi engine planes ranging in size to a Piper Scenica to a B747, C-130s and P-3s on the military side.
Are you talking about recip engine cubic inch displacement? R1830, R2800, R3350?!?

| 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.

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...

Country:  | interestingly the BBMF lanc has a different engine start proceedure to the Mynarski lanc, but the engines are numbered the same...........

Country: | The only thing I could think of is the Mynarski Lanc, being operated in Canada has an "operation spec" (Issued by Transport Canada, they work similar to the FAA here in the states) which dictates how the aircraft is operated, including start procedures. Perhaps either the operator or a DOT puke decided to have things done differently....

Are you sure this is true for all nations? Also, are you sure it was always the case? | |

Country:  | 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.
