GREAT PLANES RealFlight 7 User Manual page 134

The Aircraft Parts Tree breaks down the entire list of aircraft components and radio
data into an easy-to-use hierarchy.
The first item listed is the name of the aircraft you are currently editing, which is
considered the root item for all other items listed here. Selecting it will offer a variety
of common parameters that you can edit in the Parameter window. These include the
description of the aircraft, Launch Method, Power Plant Type, Radio Type, and
Aircraft Type.
Below the aircraft name there are additional options that allow you to customize the
individual parts of the aircraft. You also have the ability to modify the electronics and
radio program for the aircraft.
Each part belongs to a higher component, or parent, with the root being the highest
component. In return, it's possible that the part itself also has children parts that
belong to it. For example, if you wish to edit the wheel diameter on the P-51, you will
find it under the following path in the Aircraft Parts Tree:
P-51 Mustang - root of the aircraft, found at the top of the Aircraft Parts Tree list
Airframe – Contains all the physical parts of the aircraft, such as wings,
fuselage, etc.
