continue to display the reading at which the blockage occured
Q2. The altimeter is fed by:
static pressure
Q3. In case of accidental closing of an aircraft’s left static pressure port (rain, birds), the altimeter:
overreads the altitude in case of a sideslip to the left and displays the correct information during symmetric flight.
Q4. An aircraft is in level flight at FL100 over a mountain range, which extends up to 2.400 metres AMSL. If the regional QNH is 998 hPa (use 30 ft/hPa), what is the approximate terrain clearance?
1.681 feet
Q5. The static pressure error of the static vent on which the altimeter is connected varies substantially with the:

Q6. The QNH is by definition the value of the:
altimeter setting so that the needles of the altimeter indicate the altitude of the location for which it is given.

Q11. When flying from a sector of warm air into one of colder air, the altimeter will:
overread.
Q12. When the altimeter indicated 0 (zero) ft when the aircraft was parked for the night, and 1.000 ft the following morning, this shows that:
the barometric pressure has decreased by approx. 33 hPa.
Q13. The altitude indicated on board an aircraft flying in an atmosphere where all the atmosphere layers below the aircraft are cold is:
higher than the real altitude.
Q14. When flying with an indicated altitude of 3000 ft into a low pressure area, the actual altitude:
will decrease.

Q17. The error in altimeter readings caused by the variation of the static pressure near the source is known as:
position pressure error.
Q18. The density altitude is:
the altitude of the standard atmosphere on which the density is equal to the actual density of the atmosphere

time passed at a given altitude.
Q20. You are departing an aerodrome (600 ft AMSL, QNH 1012 hPa) and proceed to another airfield (150 ft AMSL) with the same QNH. After landing, which barometric setting on the altimeter makes it again indicate 600 ft?
1027
