0.00.42 PMDG 737
INTRODUCTION
NOVEMBER 2022 DO NOT DUPLICATE For Simulator Use Only
using 50% thrust just to keep the airplane moving along the
taxiway.
This enhanced physics model also provides for a more accurate single
engine taxi experience for users who wish to simulate this real world
procedure in place at some airlines.
Tiller Steering
Most large medium-to-large business jets as well as transport category
aircraft use a steering tiller during movement on the ground. The
operation of the tiller steering is not uniform across all aircraft types.
Some aircraft have tillers that provide nose wheel steering only when an
activating button is pushed while others provide steering input at all times
if the tiller is displaced, much like the steering wheel of an automobile.
Still others provide steering input via an always-on tiller and via rudder
pedal inputs. The 737 (and indeed all Boeings) fit into this last group.
The 737 has an always-on steering tiller that is capable of controlling
nosewheel steering through 78 degrees of displacement. This yields 75
degrees of actual turning effect when nosewheel slip is accounted for. In
addition to this steering, the 737 pilot can utilize up to 7 degrees of
nosewheel steering simply by displacing the rudder pedals like you would
in any small GA airplane. This provides for a simple, precise method for
maintaining centerline on long straight taxiways and also provides for
exceptional crosswind input control during takeoff and landing.
The PMDG 737 allows you to select whether you wish to steer the
airplane on the ground using only your rudder axis, or if you have two
axes available, whether you want to simulate the dual steering inputs
available via the tiller and rudder interlink. When you select RUDDER
AXIS only, you will have full steering range available to you via your
rudder pedals. When selecting a TILLER + RUDDER AXES, you will
have 78 degrees of steering via the tiller and 7 deg of steering via your
rudder axis.
