Aeroscholars Lesson 5 and 6 ReviewBy: Ava Miller
Lesson 5: The Science of Aircraft Systems
4 different kinds of systems: Hydraulics, Pneumatics, Electrics, and Mechanical
Hydraulic Systems effectively transfer force over hundreds of feet of hydraulic line without any significant loss of energy. Hydraulic reservoirs contain non-compressible fluids that transfer force to systems throughout the airplane.
Pneumatics systems transmit force through the use of a compressible fluid. They are commonly on board aircraft to provide pressurization and actuation in hydraulic systems
Lesson 5 continued
Electrical systems often actuate many devices in the aircraft and power avionics, such as lighting, ignition, etc. Flying with this system is usually called “Flying by Wire”.
Mechanical systems are actuated through rods and pulleys directly connected to the cockpit.
Lesson 5 Questions1) True or False? Pneumatics systems are ofter used to actuate hydraulic systems.
True
2) Hydraulic Systems need a reservoir of...
A) Compressible fluid
B) Non- Compressible fluid
C) Non-Compressible air
3) Fly by wire refers to
A) Use of mechanical controls to power rudders, elevators, and ailerons
B) Use of computerized systems to control the aircraft more accurately and efficiently than with human hands only.
C) Use of electrical systems to prevent system overload
4) Landing Gear that does not retract and has no retracting device is called...A) Fixed
B)Unfixed
C) Movable
D) Unretractable
Lesson 6: Aircraft Instruments
=Pitot-Static =Gyroscopic
Lesson 6 QuestionsWhich of the following is a member of the pitot-static family?A) Airspeed indicator B) Attitude indicator C) Magnetic compass
True or false? The attitude indicator receives its information from a gyroscope.True
True or false? The magnetic compass requires electricity from the aircraft electrical system to operate properly.
False The Tachometer...A) Displays the temperature of the engine exhaust B) Displays engine or crankshaft revolutions per minute.C) Displays altitude above sea level.
