I know that FS9 was always bad about being able to simulate single engine taxi due to not being able to truly simulate hydraulic nose wheel steering and such, but I have had a bit of success doing single engine taxi's with a few payware planes over the years.I just upgraded to FSX a few days ago, only have 1 payware plane on so far so I haven't really had time to experiment.I'm curious if any of the devs or testers for the NGX have tried to perform a single engine taxi before takeoff or after landing and if so, how well do the flight dynamics of FSX allow it to be done?I know the systems modeling of the NGX will allow it to work perfectly if the plane is set up correctly; its always been the flight dynamics of the sim that cause problems in the past...

When does an NG taxi on a single engine... I've never seen this on any 737 I've ever been on.

Many airlines only taxi with one engine as to save fuel. The Delta A330 I was on from Madrid-JFK taxxied on one engine. But most especially the Delta 757 leaving JFK performed the famous 45-min taxi on one engine, effeciency matter there!

Or if your flight is early, and another flight is at your gate, they usually wait in a "penalty box" and shut down an engine. Then single-engine taxi to the gate. It has happened a couple times on flights I've been on.

Last American Flight I was on they did the same thing mentioned above. I arrived at MIA and while taxxing to the gate a 757 was at our's, we had the tug push us back into a coned area, and the engines shut off, stayed there for 20 minutes then we got pulled in, a good thing to note was the sound of the tyre rolling on the tarmac, it was beautiful. How these planes work like clock work.

I do most of my siming in and out of airports like ATL and IAH so I'm used to having longer taxi times...And being a real world pilot I treat it like a "simulation" instead of a "game" and try to model real world as much as possible; that's why I choose to single engine taxi when a model allows me to. Right now I've been flying the Leo MD8X almost exclusively since it's release and it single engine taxis very well.I'm just curious if anyone has tried to do it with the NGX since I definitely will try.

SIngle engine taxis are common ops for airlines, especially in current market conditions, with high fuel prices, and forcibly low prices (due to ultra-low cost airlines). They are much more effiecient, taxxing is just as safe and fast, and for places like JFK with that legendary 45min taxi time, its saves a substantial amount of fuel.

Anytime pilots have EDCT and are taxiing out early, they tend to be on one engine. They like us to let them know a few minutes before we can let them go so they can get the other engine up and running.

How does it work? Does the airplane recognize that only 1 engine is running and it compensates for it in the nose gear?Regards

I believe that heavies such as the 76 and 77 have restrictions on single engine taxi when fully laden, I assume that when approaching mtow that too much torque is applied to the undercarriage when on a single engine.Bruce.

GOL Airlines also make use of S.E.T.O (Single Engine Taxi-out Operations), but only if taxi time to the gate is expected to be longer than two minutes, otherwise they just keep both running.And about "compensation", I.R.L, taxi ops with single engine are kinda usual, it doesn't require special taxi technique, just follow the yellow line as you always do.

I've noticed that during single engline taxi(s) on FSX the aircraft sways the opposite direction of the running engine. Does friction stop this in real life? Or the the airplane still turn?

Usually with FSX, it seems to me that you have to apply too much thrust to get moving with a single engine taxi. I've seen where some airports restrict to 40% thrust on taxi and with a single engine in FSX, it seems to always require more than that to get moving.Bob

In the real world the nose wheel is steered with hydraulic pressure. It takes a tremendous amount of force to overcome that, and yes the friction between the tire and the ground keeps the plane from yawing due to the asymmetric thrust of one engine.Unfortunately hydraulic nose wheel steering isn't modeled in flight sim, so single engine taxi becomes difficult on most planes.

Right, usually I have trouble with SE Taxi outbound, but inbound after landing it's not usually in issue since the aircraft is so much lighter.Like I said earlier I almost always fly the Maddog right now, and the tail mounted engines are so close to the axis of the airplane that there isn't much yaw produced by one engine on the ground, so I can usually taxi out and in on one engine without any trouble.I'm expecting that with the wing mounted engines of the 737 taxi out on one engine may not be possible, but I'm also new to FSX and wondered if the flight dynamics were different enough from FS9 that it might be.Either way, I'm certainly going to try it when I get my hands on the NGX, I just wondered if any devs or testers have already tried and could provide their thoughts...

With the NGX in final testing now, I wanted to give this thread a quick bump in hopes one of the testers might be able to give single engine taxi a try and leave some feedback here...Here's hoping it works, and thanks for all the effort in development; can't wait to buy this beauty.
