L-1011 Starting Engines During Taxi

Fri May 26, 2006 8:03 am

I notice that L-1011 will start two of it engines then start taxing. I even see a Delta L-1011 at LAX, taxi all the way to Runway 24 before it start it # 3 or 1 engine. I herd of 747 being able to taxi before it's finish it's engines start up, but every time I see one departing they start up four engines before taxi. Why L-1011 start there taxi before they finish starting up there engines?

It's not just the L-1011. I'd say 80% of the time I've flown on an MD-80 or ERJ/CRJ they didn't start the second engine until we were taxing out.

When did you say you saw a Delta L1011? They've been retired for some time. Perhaps ATA.

Different air carriers have individual policies and procedures for delayed engine starts. Delta taxis most of their planes on one engine to save fuel. Some shut down one or more after landing during the taxi to the gate and some come all the way in with all engines running. Some start all engines at the gate and taxi out while others start one or more as they approach the departure end of the runway and complete the before takeoff checklists.

This had to be in the late 90's or 2000. It was some time ago.

I flew on a Delta L-1011 in 2000.
While I was waiting, I also noticed that they did not start up all the
engines. Ever since then I have always wondered why.

Many airlines will taxi on the minimum number of engines, now because of fuel costs. A DL L-1011 RB-211 burned about 1 US gallon of jet fuel every 5 seconds or so.

Even at idle?

I've noticed this on AirTran as well... Every time I fly out of MKE they have done this, except once when we had to get a ground-start, and then they started both engines while connected to the Start-Cart.

In the cruise not on the ground.

There may also be a jet blast issue, the #2 engine on DC10/MD11(and possibly L-1011) are often higher than blast fences.
SYD for example has restrictions on DC-10/MD-11 on some taxiways near the domestic terminal due to jet blast concerns. I am sure there are other airports with similar issues.
