4.0 GROUND MANEUVERING

4.1 General Information

This section provides airplane turning capability and maneuvering characteristics.

For ease of presentation, these data have been determined from the theoretical limits imposed by the

geometry of the aircraft, and where noted, provide for a normal allowance for tire slippage. As such,

they reflect the turning capability of the aircraft in favorable operating circumstances. These data

should be used only as guidelines for the method of determination of such parameters and for the

maneuvering characteristics of this aircraft.

In the ground operating mode, varying airline practices may demand that more conservative turning

procedures be adopted to avoid excessive tire wear and reduce possible maintenance problems.

Airline operating procedures will vary in the level of performance over a wide range of operating

circumstances throughout the world. Variations from standard aircraft operating patterns may be

necessary to satisfy physical constraints within the maneuvering area, such as adverse grades, limited

area, or high risk of jet blast damage. For these reasons, ground maneuvering requirements should be

coordinated with the using airlines prior to layout planning.

Section 4.2 shows turning radii for various nose gear steering angles. Radii for the main and nose

gears are measured from the turn center to the outside of the tire.

Section 4.3 provides data on minimum width of pavement required for 180o turn.

Section 4.4 shows the pilot’s visibility from the cockpit and the limits of ambinocular vision through

the windows. Ambinocular vision is defined as the total field of vision seen simultaneously by both

eyes.

Section 4.5 shows approximate wheel paths of a 767 on runway to taxiway, and taxiway to taxiway

turns.

Section 4.6 illustrates a typical runway holding bay configuration.
