Servos
Moves the flight control surfaces on many light, single- engine aircraft autopilot.
What is a vacuum servo?
what does BITE stand for?
Built in test equipment
An auto-pilot uses this type of signal to correct the airplane's attitude.
The main purpose of an auto-pilot system is to...
What is lower the pilot's workload?
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
Describe a heads-up guidance system
A panel used by the pilot to select auto-pilot modes.
Autopilot control panel
The roll axis.
Name 2 things a flight management computer interfaces with.
EICAS or ECAM
Air data computer
Thrust management computer that controls the autothrottle functions
EFIS symbol generators
Automatic flight control system
Inertial reference system
Collision avoidance systems
All of the radio navigational aids via data busses
What is required of all autopilot systems, that is easy to access by the pilots?
ALL autopilot systems must have an emergency disconnect so that the autopilot can be over-ridden by the pilot.
Name 5 aural warning devices, which would be the most commonly found on aircraft?
Stall warning. Landing gear, fire warning, Mach warning, Runway Stabilizer.
What is an old school type of flight deck screen?
Cathode Ray Tube or CRT.
Uses a capstan to connect the auto-pilot servo to the flight control cables.
What is an electric servo?
What is EICAS
Engine Indicating and Crew Alerting System
A two axis autopilot is controlled on which axes?
Roll and pitch.
What is the 5th element of some autopilots
Feedback or followup.
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.
Where do you find what the correct range markings for an instrument?
TCDS or pilot's handbook.
Connects the flight control cable to the servo when using a vacuum servo.
What is a bridle clamp?
The auto-pilot mode that commands the auto-pilot to follow VOR navigational signals.
What is NAV mode?
Autoland needs how many axes?
Three.
What is used to counteract Dutch roll?
Yaw damper system.
What do ADI and HSI stand for? What electronic instrument displays them?
Attitude Director Indicator/Horizontal Situation Indicator; EFIS or EADI.
What are the 3 colors of indicated lights on an annunciator panel and what do they represent?
Why do shock mounted instruments need bonding?
Because the rubber shock mounts insulate between the instrument and the aircraft structure, preventing a path for static electricity and lightning strikes to pass harmlessly from the aircraft.
What is an EADI and what indications does it typically display?
What is an EHSI and what indications does it typically display?
EADI "Electronic Attitude Director Indicator": Displays aircraft attitude and many situational flight parameters such as altitude, airspeed, and vertical speed.
EHSI "Electronic Horizontal Situation Indicator": Displays directional information and as much useful navigational information as possible. Can switch between PLAN, MAP, VOR, and ILS modes.
Which axes are involved in Dutch roll?
Yaw and roll.
The auto-pilot component that provides command bar information for the HSI.
What is the Flight Director ?
What are the 4 basic subsystems of an autopilot system?
Sensing computer output and command
What does a master caution do, and what is it for?
It sounds a bell and lights up; it warns the pilots that there is a problem, but it doesn't specify what the problem is - it prompts the pilots to investigate and discover the problem.
What do each of these colors mean, on instruments?
Red radial line
Red arc:
White arc:
Yellow arc:
Green arc:
Blue radial:
What do each of these colors mean, on instruments?
Red radial line: never exceed.
Red arc: prohibited range
White arc: special operations range (e.g.: flaps extended speed).
Yellow arc: Caution
Green arc: normal ops
Blue radial: special operating condition
