Test 1 Flashcards
(27 cards)
What are two groups aircraft instruments can be categorized into
Means of operation
-How the instrument works
Application
-What information is sent to the pilot
What are four different types of instruments
Pressure
Mechanical
Gyro Driven
Electrical
Examples of a pressure instrument
air, fuel and oil
Direct Reading Instrument
Measures/ senses applicable properties
Remote Reading
rely on some type of transmitter which translates the sensed value from the detecting element
Examples of a power plant instrument
thrust, torque, prop speed
Examples of flight and navigation instruments
attitude, speed, altitude
Examples of System Instruments
electrical, hydraulic and pressurization
Primary Instrument
directly apply to the immediate control and navigation of the aircraft
- Attitude, navigation
Secondary Instrument
Observed infrequently
-Engine instruments, fuel system, electrical system
Tertiary Instrument
Those that are referred to as the need arises
-OAT, brake pressure, checklists
What are three most common methods to install an instrument
non-magnetic screws, circumferential clamps, brackets
Red radial line
max or minimum operating limit
Red Arc
Prohibited range of operation
Yellow Arc
Cautionary range
Green Arc
Normal operating range
Blue arc or line
meaning specified by manufacturer- airspeed for best single engine rate of climb
Shock Mounts
Minimizes panel vibration
Must be in good condition
must not exceed weight carrying capability
Bonding Jumper Functions
Ground return path
reduces RF interference
decreases lightning strike damage
dissipates static charges/prevents arcing
The detecting element
detects the physical quantity or condition
The measuring element
measures the value of the quantity or condition
The coupling element
displacements are magnifies and transmitted
The indicated element
exhibits the value by the relative position of a pointer or index and a scale
Quantitative
numbers
