ACCIDENT INVESTIGATION REPORT WRITING Flashcards
includes the cabin and/or cockpit, which contains seats for the occupants and the controls for the airplane.
FUSELAGE
may also provide room for cargo and attachment points for the other major airplane components.
FUSELAGE
Two General Types of Fuselage Construction
Welded Steel Truss
Monocoque designs
was used in smaller Navy aircraft, and it is still being used in some helicopters.
Welded Steel Truss
relies largely on the strength of the skin, or covering, to carry various loads. This structure can be very strong but cannot tolerate dents or deformation of the surface.
Monocoque designs
Three classes:
True monocoque
Semi monocoque
Reinforced shell
has the skin reinforced by a complete framework of structural members.
Reinforced shell
Semi monocoque
overcomes the strength-to-weight problem of monocoque construction.
construction uses formers, frame assemblies, and bulkheads to give shape to the fuselage.
True monocoque
are airfoils attached to each side of the fuselage and are the main lifting surfaces that support the airplane in flight.
Wings
Wing structures carry some of the heavier loads found in the aircraft structure. The particular design of a wing depends on many factors, such as
the size, weight, speed, rate of climb, and use of the aircraft.
includes the entire tail group, consisting of fixed surfaces such as the vertical stabilizer and the horizontal stabilizer.
Empennage
maintains the stability of the aircraft about its vertical axis which is known as directional stability
Vertical Stabilizer
provides stability of the aircraft about its lateral axis which is known as longitudinal stability
Horizontal Stabilizer
is a primary flight control surface that controls movement about the lateral axis of an aircraft. This movement is referred to as “pitch”.
Elevator
is a primary flight control surface which controls rotation about the vertical axis of an aircraft. This movement is referred to as “yaw”.
Rudder
is specially designed to support the load of an aircraft during surface operation and when landing. It is the principal support of the airplane when parked, taxiing, taking off, or when landing.
Landing gear
Types of Landing Gear
Conventional Landing Gear
Tandem Landing Gear
Tricycle-Type Landing Gear
This type of landing gear utilizes two main wheels located ahead of the center of gravity to support the majority of the weight of the aircraft.
Conventional Landing Gear
It features the main gear and tail gear aligned on the airplane’s longitudinal axis. This allows for the use of flexible wings on both sailplanes and select military aircraft.
Tandem Landing Gear
The most common type of landing gear, These includes the main gear and the nose gear. It’s typically used on both large and light aircraft
Tricycle-Type Landing Gear
usually includes both the engine and the propeller. The primary function of the engine is to provide the power to turn the propeller.
