Section 91-00 General This chapter contains the wiring diagrams, schematics, and wire lists for the Liberty Aerospace, Inc. XL-2 airplane. These drawings are up-to-date as of the release of this chapter and are for general information only. Table 91-1 has the list of Liberty Aerospace, Inc. drawings and their current versions and forms a part of this chapter by reference. However, the most current version levels available from Liberty Aerospace, Inc. of these drawings should be used as the definitive source for information.

Section 00-02 Wire Numbering Each wire in the XL-2 airplane has a unique number. The number defines what circuit or system the wire belongs to, the route for the wire, the route subsection, the gauge of the wire, and if the wire is a travelling ground.

Table 91-2 gives the system description for the subsystem designation on the wire number. The route subsection designation for the route from source to termination.

Sub System Designation System Description

A Antenna

AP Autopilot

C Clock and Facility socket

E Fuel System

EGND Earth Ground – ground to aircraft frame

F FADEC

G Gyro Instrumentation

H Pitot Heat, Hour Meter, Outside Air Temperature

IGND Instrumentation Ground – ground path isolated from Earth Ground

JPR Jumper Wire

L Lighting

P Power Distribution

R Avionics General

RD Avionics Display Systems (glass cockpit)

RG Avionics Garmin

RU Avionics UPS Aviation Technologies

SP Splice

ST Solder Sleave

T Trim Flaps

V VM1000FX

W Annunciation, Stall Warning

Section 00-03 Wire Color Code Designation Table 91-3 defines the abbreviations used in the schematics for various wire colors. If a wire has multiple colors, the different colors are separated by a forward slash ( / ) between each color. The base color is first, followed by the second significant color then the third significant color and so on.

For example, a wire that has a blue base color, then red then green, would have the designation BLU/RED/GRN.

Color Code Color

BLK Black

BRN Brown or Tan

RED Red

ORG Orange

YEL Yellow

GRN Green

BLU Blue or Azure

VIO Violet or Purple

SLT Grey or Slate

WHT White

SLD Shield

TIP Center conductor of a Coax Cable

Section 91-02 Schematic Diagrams This section contains schematic diagrams for the Liberty Aerospace, Inc. XL-2 airplane. These diagrams are for reference only and can be used for basic troubleshooting. The Liberty Aerospace, Inc. drawings called out in Figure 91-3 through Figure 91-5 and Table 91-1 are the most up-to-date and should be used as the most accurate. Differences between these drawings and a specific airplane are due to updates and changes that occurred after production of the airplane.
