Basic Instruments
This instrument measures an aircraft’s height above sea level.
What is Altimeter?
Pressure from still air.
What is still pressure?
The airspeed indicator is a sensitive ______ pressure gauge.
What is differential?
The number read directly from the dial.
What is indicated airspeed?
A wind from behind that increases groundspeed.
What is tail wind?
This instrument measures rate of climb or descent in feet per minute.
What is the VSI?
Pressure created as a result of motion.
The only flight instrument that uses the pitot tube.
What is Pitot tube?
IAS corrected for instrument and installation error.
What is calibrated airspeed?
A wind from ahead that decreases groundspeed.
What is head wind?
his instrument measures airspeed using dynamic and static pressure.
What is the Airspeed Indicator/
Dynamic pressure equals this minus static pressure.
What is total pressure?
Inside the airspeed indicator is this expandable disk.
What is Diaphragm?
CAS corrected for temperature and pressure.
What is True airspeed?
Pilots use groundspeed to calculate these two things.
What is time to destination and Fuel usage?
The altimeter displays altitude in this unit.
What are feet?
When an aircraft is sitting still, dynamic pressure equals this.
What is zero?
The pitot tube measures this type of pressure.
What is total(ram) pressure?
TAS adjusted for wind.
What is Groundspeed?
Standard sea level temperature in Celsius.
What is 15 degrees Celsius?
The VSI displays vertical speed in this unit per minute.
What are feet per minute?
Total (ram) pressure equals these two pressures added together.
What is Dynamic and Static pressure?
Both the altimeter and VSI use this system.
What is Static system?
To estimate TAS, add this percentage per 1,000 feet.
What is 2%?
Standard sea level pressure in inches of mercury.
What is 29.92 in Hg?
