Lesson 6 Worksheet
1. Which instruments are parts of the “Alpa T”?
Airspeed attitude indicator, altimeter heading indicator
2. In “round-dial” instruments, which ones receive static information?
Altimeter, airspeed, vertical speed
3. T/F – The ADC does not measure raw static and pitot pressure.
false
4. T/F – If the altimeter has an accurate pressure setting in the Kohlsman
window, it will
show Mean Sea Level.
True
5. What is pressure altitude?
The altitude relative to standard pressure at sea level. Used to determine
plane performance.
6. You are flying from an area of high pressure to an area of low pressure and
you fail to
reset your altimeter. What is the relationship between the aircraft
and altimeter?
It is lower than the altimeter indication
7. Indicated airspeed which has been corrected for instrument and position
error is
called what?
Calibrated airspeed
8. How is never exceed airspeed indicated on an airspeed indicator?
A red line
9. In a zero wind situation, which airspeed increases as you climb in altitude
in a
turbocharged airplane?
True airspeed
10. What flight information is shown on an artificial horizon (attitude
indicator)?
Pitch and bank
11. How fast is a standard rate turn?
360 degrees in 2 minutes
12. Airplane A has an airspeed of 100 MPH, airplane B 120 MPH and
airplane C 140
MPH. All three airplanes are indicating a standard rate turn on
the turn needle. Which
airplane has the steepest bank angle?
Aircraft C
13. What does AHRS stand for?
Attitude heading reference system
14. T/F – Loss of the AHRS will affect the ADC.
False
15. What does GCU stand for?
Garmin Control Unit
16. What is magnetic variation?
The angular difference between true and magnetic north.
17. T/F – Deviation is something that we never have to correct for when
flying an
airplane.
false
18. Northerly turning error causes the magnetic compass to either lead or lag.
You are
turning left to a heading of 180
o
. Therefore, you should roll out of
the turn when the
compass reads what?
150 degrees
19. In the Northern Hemisphere, if an airplane is accelerated on a heading of
060º, what
will the magnetic compass indicate?
A turn toward north
