The Local and Ground Controllers are often coordinating with each other to have a landing aircraft follow a taxiing aircraft at a specific intersection; there might be another landing aircraft on short final or the Tower Controller might have an aircraft slotted for immediate takeoff.
When an aircraft comes to a complete stop on the runway, we are wonding what is happening out there. The aircraft then comes up on the power and slowly inches off the runway -- while the Local Controller sits poised with his thumb on the mike button waiting for the "GO AROUND!" or "CLEARED FOR IMMEDIATE TAKEOFF!" command to be transmitted.
Can someone shed some light on the subject? It's always an Airbus.

Don't worry about it. I've already beat the dead horse of what an arrogant SOB he is.
Somebody told me once that he is the AP forums equivilant of FI's SWAFO who works for SW.
I believe it.

Hello everybody,
does the outer tire of the nose-gear only come of the earth in tight turns on the MD-11? Or does that happen on all aircraft. It seems logic. But if it is only on the MD-11 (DC-10?) what is the reason for this? And does this not put alot of stress on the nose-gear?
Thanks in advance
regards
Jakob

The nose landing gear on the DC-10/MD-11/MD-10 does not project straight down from the fuselage, but rather angles forward. Consequently, when the nosegear turns away from dead center in either direction, weight is transferred progressively to the "inside" tire, to the point where the outside tire will actually lift off the ground at light weights (or at aft CGs).
Reason? I dunno. I didn't design it, I just fly it.
However, I feel pretty certain the engineers designed the nosegear to survive the failure of a single nosegear tire during a takeoff or landing, so I would assume 1 tire can bear the entire load. Furthermore, limiting speeds for turns while taxiing must prevent excessive side loads on the gear and the tires. I'm guessing they figured all that stuff out before they even started building the airplanes, and the fact they carried the design forward to the MD-11 from its predecessor leads me to believe it worked out OK.
It's the main landing gear that I'm not so sure about.
