Structures Flashcards
What is the construction material for principal structures?
All metal construction
What type of panels are used for floors?
Bandalite/aluminum honeycomb
What is a key design principle that ensures safety in structures?
Fail safe design principals
Name one of the fail safe design principles.
Multiple load paths
What do crack stopper bands do?
Prevent crack propagation
What is the significance of small panel sizes in structural design?
They help maintain low stress levels
Where are open drain holes located?
In unpressurized areas
What type of drain holes are found in pressurized areas?
Drain holes with check valves
What is accessible through a removable radome in the unpressurized nose section?
Avionics Compartment
The avionics compartment contains essential electronic systems for aircraft operation.
What maintains the temperature in the avionics bay?
Two avionics bay cooling fans automatically activate to maintain an 80-95 degree F temperature range
This temperature range is crucial for optimal functioning of avionics.
What type of doors are found in the baggage compartment?
Swing-up, key lock doors on each side
These doors allow for secure access to the baggage compartment.
What is the maximum baggage capacity in cubic feet and weight?
24.4 cubic ft / 400 lbs maximum
This capacity is important for understanding the load limitations of the aircraft.
What feature ensures visibility when accessing the baggage compartment?
Courtesy lights from hot battery bus
The light extinguishes regardless of switch position when the door is closed.
Where is the equipment area located?
Copilot’s side, accessible through outside fuselage and through the floor and bulkheads
This area contains various essential components for aircraft operation.
List the components found in the equipment area.
- Alcohol Reservoir
- Pneumatic Bottle
- Brake fluid Reservoir
- Oxygen Bottle
- Antiskid Components
These components are critical for the aircraft’s safety and performance.
What are the two components of the flight compartment?
Two complete crew stations
This indicates that the flight compartment is designed for two crew members.
What features are included in the cabin?
- Passenger seating (lateral and fore/aft tracking on rear four seats)
- Aft baggage compartment/toilet: 4 cubic feet / 100 lb
- Storage cabinets
- Refreshment bar
The cabin is designed for passenger comfort and storage.
What is the function of the cabin door?
Opens outward (can be opened from inside or outside)
This allows for easy access for both crew and passengers.
How many locking pins does the cabin door have?
Twelve locking pins
These ensure the door is securely locked during flight.
What activates the DOOR NOT LOCKED annunciator?
Lower forward locking pin
This mechanism provides a warning if the door is not properly locked.
What is the purpose of the mechanical latch in the cabin door?
Allows for interior release
This feature enhances safety by enabling the crew to open the door from inside.
How many lock indicator windows are on the cabin door?
Five lock indicator windows
These windows provide visual confirmation of the door’s locked status.
What do the six green indicators signify on the cabin door?
Door is closed and locked
This visual cue is crucial for safety checks by the crew.
What does the plunger do when the lower forward locking pin is depressed?
Allows bleed air inflation of the door seal
This action enhances the sealing of the door, improving cabin pressure integrity.
