Single engine taxiing

[IFLover]

is there any way to know which airlines do/don’t single engine taxiing?

This could help:

AFAIK, all planes (atleast the ones we have in IF) are allowed to single engine taxi. It mostly depends on the airlines procedures and policies.

I single engine taxi to save fuel for long haul flights

[avChes]

At WN, most of our guys will taxi single engine obviously to save fuel during long waits on the ground etc. Other times we just want to leave ASAP to catch up on time and can’t be bothered waiting for our second engine to start up, especially for the Maxes. 🤣

I’m pretty sure single engine taxi is not an approved procedure on the A380/B747…

In general it’s more common to taxi in without all the engines running than it is to taxi out. Not all engines are created equal either, some can be shut down during taxi in while others must be left running, for example:

B747-400 - engine 3 is most commonly shut down during taxi to gate. Engine 2 may be off as well but this is less common.

A340-600 - a similar situation where the outboard engines are to be left running. Engine 3 can be shut down in most cases and Engine 2 as well if lighter.

A320 family - Engine 1 is used for single engine taxi.

A330 - same as above

A380 - if I’m not mistaken it can taxi on two outboard engines (1, 4) (although I have to further verify this.)

You have it all right except for the A380, you have to taxi with engine 2 and 3 (inboard) because the others engine are overhang the taxiway and can pickup debris (IRL) as you need a bit more power to move.
And it help with aircraft stability overall.

For the 747 it’s needed to have all four engine for taxi out (take off) and you can shut the two outboard engine for taxi in (after landing).

In the vast majority of, if not all cases indeed,

Inboard engines. Shutting the outboard engines on the 747 would mean essentially losing all nose and body gear steering (Engine 1 hydraulics) and braking (Engine 4 hydraulics) in reality.

Some maintenance crew thought it was a good idea to taxi on engines 2 and 3 only on a Saudia 747-300 a while back - they ended up destroying the plane in a ditch.
