Towing aircraft on airfields
As someone interested but with no involvement in aviation, I was thinking of collisions whilst taxying, aircraft getting onto the wrong runway, fuel wasted in getting to & from the runway, etc.
Why not have the planes towed out all the way and just start engines a few minutes before takeoff & shut down after leaving the runway? Power for radios, lighting and so forth could be provided via a link from the towing vehicle.
Teams of dedicated tugs could be equipped with GPS so that both they and controllers know exactly where they are.
Possibility of errors would be less anyway because, unlike pilots, the drivers would be familiar with the layout and procedures of only one airport as well as any recent changes thereof.
A second crew member could be watching the wings to ensure that they miss parked aircraft, vehicles, etc.
I expect that accidents and fuel costs would both be minimised, especially in poor visibility.
This is not happening so where am I going wrong?
