Numbering Engines
When hearing about engine problems ie No 3 engine failed or start up no 2, 3 & 4 what is the order of engines on a 747 or a twin jet?
Is it left to right 1 - 4 or the other way round? Cheers. |
If you are sitting in the aircraft looking forward, No 1 is on your far left, No 2 on your near left, No 3 on your near right and No 4 on your far right.
Simples! |
Normal engine start up on ground or engine re-start after all have failed in flight?
On a twin prop, if both props rotate clockwise as viewed from behind, engine 1 is the critical engine and would be started first if both failed in flight. edit: Just realised you were only asking about the engine numbers, not start sequence. It's been a long day! |
Well I hope you enjoyed it anyway.
From port to starboard. Got it:ok::ok: Thanks to you both. |
Hi,
Just wondering what the ordering would be on a 3 engined aircraft. Would the one in the tail be no 2 or 3? Sorry for the stupid question Thanks |
tail engine ( as in a DC-10 or L1011 for instance ) is the No. 2
|
Its a very valid question not a stupid one.
|
Thanks Guys :ok:
|
However, on a twin, some airlines refer to them as.... Left and Right.
No numbers. |
some airlines refer to them as.... Left and Right. I thought after the British Midland B737-400 came down on approach to EMA, the lesson was that absolutes were more helpful than left and right which depends on which way you're looking! |
rubbish L337 the only people who refer to engines as left and right are the spotting fraternity:eek:
|
How are they numbered on a Cessna Skymaster ?
I'll get me coat..... :O |
Actually skipness i speak to a fair few older pilots who still use the term port
and stbd when identifiying engines , perhaps its a old airforce habit as engines were at one time refered to that way, for eg, on a four engined a/c engine #1 was port outer #2 port inner etc |
No I agree, port and starboard are the absolutes I was referring to.
are the spotting fraternity |
kevlarcarl. rubbish L337 the only people who refer to engines as left and right are the spotting fraternity Whilst on approach to London (Heathrow) from Beijing, China, at 720 feet agl, the right engine of G-YMMM ceased responding to autothrottle commands for increased power and instead the power reduced to 1.03 Engine Pressure Ratio (EPR). Seven seconds later the left engine power reduced to 1.02 EPR. This reduction led to a loss of airspeed and the aircraft touching down some 330 m short of the paved surface of Runway 27L at London Heathrow. The investigation identified that the reduction in thrust was due to restricted fuel flow to both engines. |
Skymaster?
IIRC from a brief experience with one at Kidlington in 1973 (and endless discussions on the REAL need for a twin rating and assymetric training in order to fly it) the front one was No 1 and the rear one was No 2. The throttles were side by side with No 1 (the front engine) nearest you and No 2 to the right of it. |
On a twin prop, if both props rotate clockwise as viewed from behind, engine 1 is the critical engine and would be started first if both failed in flight. |
the only people who refer to engines as left and right are the spotting fraternity |
the only people who refer to engines as left and right are the spotting fraternity Maybe they are frustrated spotters.........:ok: |
I have an old Victor B2 manual which desribes them as Port Outer, Port Inner, Starboard Inner and Starboard Outer. When I flew it as the K2, they were referred to as 1,2,3 and 4.
