Door types
Clamshell-style 30” wide
Door components
Attached to the upper door are gas struts
Attached to the lower door are gas dampers, 2 integral steps & a flip down step
How the Door is opened from the outside
Lift the upper door operating handle from its recess and rotate it with both hands clockwise to the full travel position
• Pull the upper door out and upward
• Reach inside and rotate the lower door operating handle clockwise to the open position
• While holding the lower door, lift the secondary latch lever on the forward side of the door frame to release the door
• Gently lower the door until it is suspended by the gas struts
• The flip-down step rotates to the down position as the door is lowered
How does Door Locking work?
Locking is accomplished by the extension of latch pins into the door jamb.
How many latch pins are there
4 lower door
6 upper door
2 in the upper engage the eyelets attached to the lower door
How is proper latch pin extension verified?
Inspection windows &
The red ‘ENTRY DOOR’ light illuminates on crew warning panel any latch pin is not fully extended
Turbofan engine
TFE 731-20 engines (3500# thrust @ sea level)\
Hydraulics.
How many?
What is critical?
What operates off of it?
2 engine driven systems
redundant and situational
– if in doubt take the breaks over reversers or flaps
– operates spoilers, spoilerons and flaps
– everything else is mechanical
Brakes and Steering
Brake by wire and Steer by wire systems
– Brakes are pretty beefy
Electrical
- Generators (no inverters)
- Components handle conversion of power themselves
- Alternators only used for windshield heat
Glass Cockpit
– utilizes 4 MFD’s (info interchangeable) / EICAS normally on MFD #2
– can also be shifted to RMU in case of failures
Unpressurized areas
Nose, fuel, tail
Does it float?
Not certified for ditching
(FGCS) Flight Control Guidance Control System functions include?
- Two-axis fail-passive autopilot/yaw damper
- Dual independent flight directions
- Automatic Pitch Trim
- Yaw Damper System
- Mach/configuration Trim System
Main system components of the FGCS consist of the:
- IC-600 integrated avionics computers (IACS)
- Flight guidance controller (FGC)
- Servo Motors
FD1 Button (AP engaged)
Press- if autopilot is engaged
- no effect if FD1 is the master FD
- Removes pilot FD command bars and annunciations if FD2 is the Master FD
FD1 Button (AP disengaged)
Press- if autopilot is not engaged
- No effect if no FD modes are selected
- Removes both pilot and copilot FD command bars and annunciations if FD1 is the master FD
-Removes pilot FD command bars and annunciations if FD2 is the master FD
