Access to the aft equipment bay is provided
on the right side of the tailcone section. This
compartment houses major components of the
electrical, environmental and engine fire ex-
tinguishing systems. This door is hinged at the
bottom and secured by two latches.
The locking pins on the tailcone access door
and on the tailcone baggage door contact
microswitches when closed. If any of the
microswitches for the doors are not prop-
erly mated, an amber “EXTERNAL DOORS”
CAS message is displayed on the EICAS
(Figure 1-12). This CAS message is also dis-
played when either door is opened.
WING
The Learjet 45 wing, as shown in Figures 1-
17 and 1-18, is a swept (13°) high aspect ratio
planform with tapering thickness. The wing
structure is continuous through the fuselage
cutout and is provided with four load attach-
ment points on each side for mating to the
fuselage.
Most of the wing is sealed to form integral fuel
tanks on each side.
Specific wing features are as follows:
• Winglets at the outboard end of each
wing reduce the strength of the wingtip
vortices, thus reducing induced drag.
• Removable aluminum alloy leading edge
t h a t h o u s e s t h e p i c c o l o t u b e w i n g
anti–icing system.
• Supercritical airfoil design with flush
rivets to delay shock wave formation
and minimize drag.
• Wing twist or droop (3°) is incorporated
to allow for better low speed handling
characteristics (delay stall at wingtip).
