With prices of fuel going up every day would it be possible for aircraft manufacturers to make one or both main bogies powered .?
Instead of using the jets would this be possible and would it be economical .
I now see a lot of tugs at Airports pushing and pulling aircraft around to save fuel .
Any thoughts would be appreciated

It would save fuel on the ground.

But, something that powerful would probably weigh a lot. I cannot imagine that something which weighs several hundred pounds could actually save fuel on a five hour, ten hour, or eighteen hour flight.

Doubtful, I would think the weight of making them powered, as well as the extra space would null any fuel saved for taxi. Besides, I think using the engines for taxiing gives them a chance to get everything running and lubricated for the flight, as well as a chance for the pilots to see if everything is normal.

JumboJim747: I dont think Tugs are taxing planes around. They might just from a long term parking area to the gate. Or gate to Parking or Gate to Hanger. But you wont see a tug take a plane to a runway or from the runway to gate unless the plane does not have any power.

Quoting FlyMIA (Reply 3):

It kinda did on my AA 767 flight from JFK to AUA last summer.

The flight boarded and departed 15 mins early.
Then the captain said the tow bar broke and the rampers went out looking for another one.
2 mins later the plane starts pushing back, it does a left 90* turn, then it went foward and the engines were still off.
Then it stopped for a second, then it went foward, then to the right after 20-30 seconds, then straight to the taxi-way entry, I see the tug and the walkers hop on and they took off. That was after 3 to 5 mins since pushback began.
At the same time the engines were starting.

Well some airports are different. And it depends on what gate to. Some gates in MIA need a plane to be tuged in. Still a tug is not going to taxi a plane to the runway.

Besides, the engines have time to get nice and warm during the taxi so it's not directly wasted engine time. You wouldn't want to start an engine and go straight to take-off power.


I thought I was doing good trying to avoid those airport hotels... and look at me now.

These towbarless tugs are a more practical idea than putting a drivetrain to the wheels.

But we still need thermal stabilization of our engines before taking off.

Towbarless tugs are great. I just flew out of A-2 (satellite terminal) at DFW, and the ERJ I was on had a much, much smaller tug than in the picture above. It looked more like a lawnmower. The operator stood on a small platform at one end of the tug and steered with a large wheel. There was no enclosure. It was almost comical to see these tiny tugs pulling ERJs around the ramp area, some of them empty and traveling at a higher speed than would normally be used for taxiing!

The last time I was through that area (about two months ago) they were still pushing back ERJs with towbars.

On another DFW note, I saw the SkyTrain running around the main airport building complex, and was excited to think I might finally get to ride it! Sadly, it was not yet in service, and must have been running just for testing. The 1970's Robo-TrAAin is still in service, for now.
