Autopilot/Electronic System Flashcards
What are the three 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.
What are the two types of autopilot follow-up systems?
Rate and Displacement
what are the four basic subsystems of an autopilot system?
Command
Error-sensing
Correction
Follow-up
Which subsystem of the autopilot system could you consider the ‘“brains”
Error-sensing
Which subsystem of the autopilot system could you consider the “muscles”
Servos in the controller system
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
Name five common aural warning devices, which would be the most commonly found on all aircraft?
Stall warning
Landing gear
Fire warning
Mach warning
Runway stabilizer
Where can you find the requirements for aural warning systems?
Sections of FAR part 25
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 flight deck effects happen when landing gear is not down and locked, flaps are less than full retracted, and throttle is retarded to idle?
The landing gear warning system will signal the pilot with a continuous horn
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 are the three colors of indicated lights on an annunciator panel and what do they represent?
Green: indicates satisfactory condition
Yellow: indicates caution of a serious condition that requires further monitoring
Red: indicates unsatisfactory condition that requires immediate action
What are the three 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)
Explain what the EICAS system is and what is monitored?
Engine Indication and Crew Alerting System. Monitors primary and secondary engine parameters, engine oil parameters, engine vibrations, and has an alert message field
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
What does BITE stand for?
Built-in Test Equipment
Give three examples of the type of work A&P mechanics can do on electrical components
Inspect
Troubleshoot
Remove and reinstall
New installations STC form 337
Explain three 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 surface hinges
Reduce fire hazard by eliminating static charge sparking
What must be recalculated after you have completed a new install of electronic equipment?
Weight and balance of the aircraft
What are the maximum number of terminals that can be added to a stud?
Four terminals is max to add to any one stud
Explain what static discharges (wicks) are for
Help eliminate radio interference by dissipating static electricity into the atmosphere at low current levels
What does EFIS stand for?
Electronic Flight Instrument System
What does ECAM stand for?
Electronic Centralized Aircraft Monitoring System
What does EFIS indicate?
Basic pitch and roll, attitude, airspeed, and vertical speed scale
What does BITE perform?
Digital systems may automatically do a self-examination of their operating condition and diagnose the faults found
