Autopilot
What is required for ALL autopilot systems?
ALL autopilot systems must have an emergency disconnect so that the autopilot can be over-ridden by the pilot.
Explain the significance of aural warning systems for aircraft.
Loud and clear audible sounds to warn the crew of a serious problem or the aircraft in the wrong configuration for that stage of flight.
What does BITE stand for?
Built-in Test Equipment
What are the maximum number of terminals that can be added to a stud?
4 terminals is max to add to any one stud
Which subsystem of the autopilot system could you consider the “brains” and which one the “muscles”?
Error-sensing acts as brains; Servos in the Correction system acts as the muscles
Explain what type of work an A&P mechanic is allowed to perform on aural warning systems?
Inspect and test the system and repair where allowed per AMM
What are the 3 colors of indicated lights on an annunciator panel and what do they represent?
What must be redone after you have completed a new install of electronic equipment?
Weight and balance of the aircraft
What are the 3 types of autopilots and rotation about what axis do they control?
Single-axis: roll; Two-axis: roll and pitch (some have yaw dampener); Three axis: roll, pitch and yaw
Where can you find the requirements for aural warning systems?
Sections of FAR part 25 and FAR 23.729
What are the 3 modes of display of an ECAM that can be selected and which mode would have priority?
Flight phase mode. Advisory mode. Failure-related mode (Takes priority)
Give 3 examples of the type of work A&P mechanics can do on electrical components.
Inspect, T/S, R/I, new installations IAW STC, form 337, ECT..
Repair if mechanic works at CRS or AMM states it is allowed
What are the 4 basic subsystems of an autopilot system?
Command, Error-sensing, Correction, Follow-up
Name 5 common aural warning devices, which would be the most commonly found on all aircraft?
Stall warning. Landing gear, fire warning, Mach warning, Runway Stabilizer.
Explain what the EICAS system is and what is monitors?
Engine Indicating and Crew Alerting System: Monitors primary and secondary engine parameters, engine oil parameters, engine vibrations, and has an alert message field
Explain what static discharges (wicks) are for.
Help eliminate radio interference by dissipating static electricity into the atmosphere at low current levels.
What are the two types of autopilot follow-up systems?
Rate and Displacement
What flight deck effects happen when landing gear is not down and locked, flaps are less than fully retracted and throttle is retarded to idle?
The landing gear warning system will signal the pilot with a continuous horn.
What does the EICAS DATA interface with?
Maintenance control display panel, flight control computer, thrust management system, flight management computer, radio altimeter, air data computer
Explain 3 reasons why bonding wires are used?
They reduce radio interference by balancing the static electricity throughout the aircraft structure. Decrease possibility of lightening damage to control surfaces hinges. Reduce fire hazard by eliminating static charge sparking.
