Aircraft Flight Instruments Flashcards
The Pitot -Static system is made up of:
Pitot tubes and Static Ports
Pitot tubes are mounted
On the fuselage to sense ram air pressure
In the Pitot-Static system, pressure is routed to:
Central air data computers and then to airspeed indicator
Although it varies by aircraft, Pitot Tubes are mounted on:
Each side of the aircraft fuselage aft of the radar dome
In order to prevent icing, pitot tubes are:
Internally heated
Pitot tube heat is controlled by switches on the:
Anti-icing panel
What components
- Sense atmospheric pressure
- Use openings, or ports, on each side of the fuselage
- Are not affected by ram air pressure
Static Ports
This flight instrument works by measuring the difference between static pressure, captured through one or more static port(s) and total pressure due to “ram air”, captured through a pitot tube
Airspeed indicators
Airspeed indicators show aircraft forward velocity in:
knots
This flight instrument measures static pressure and displays as feet above Mean Sea Level (MSL)
Altimeter
Kollsman window
corrects for non-standard pressure
Altimeter measurement is compared to a:
Calibrated pressure reference (CADC)
Flight instrument that senses the rate of change in static pressure resulting from a change in aircraft altitude
Rate of Climb Indicator (VVI of VSI)
The rate of climb indicator displays:
The rate at which the aircraft is gaining or losing altitude
The Rate of Climb Indicator is used to establish:
A rate of ascent or descent, or to maintain level flight
The Rate of Climb indicator is calibrated in ___________________ and indicates up to ___________________
Thousands of feet per minute
6,000 feet per minute
This flight instrument displays the aircraft’s altitude in relation to pitch and roll
Attitude Director Indicator (ADI)
The Altitude Director Indicator (ADI) works using a:
Gyroscope to establish an inertial platform
This flight instrument shows the aircraft’s heading relative to magnetic north
Magnetic Compass
When using a magnetic compass, correction must be applied for ___________
“magnetic deviation”
This flight instrument is also known as the directional gyro, or DG
Heading indicator
The heading indicator or DG displays the aircraft’s heading with respect to ____________
magnetic north
The internal gyroscope of the heading indicator is subject to _____________
drift (precession)
This flight instrument aids the pilot in making coordinated turns
Turn and slip indicator
This flight instrument provides a continuous indication of aircraft attitude in pitch and roll
Standby Attitude Indicator
The standby attitude indicator operates ______ from all other navigation systems.
Independently from all other navigation systems
This flight instrument is a magnetic heading reference provided by two independent compass systems
Directional Indicating Systems
Each compass system in the direction indicating system is:
- Stabilized by the associated inertial platform
2. Receives magnetic inputs from its individual flux valve
Heading is displayed:
- On the radio magnetic indicator (RMI) compass cards at all times
- On the electronic horizontal situation indicator (EHSI) compass cards
