reduce the effect of friction in the linkages
Q5. 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
Q6. The density altitude is:
the altitude of the standard atmosphere on which the density is equal to the actual density of the atmosphere
Q7. 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.
Q8. Without readjusting the barometric setting of the Altimeter, it will under-read when:
flying from a low pressure area into a high pressure area.
Q9. If the static source of an altimeter becomes blocked during a descent the instrument will:
continue to display the reading at which the blockage occured
Q10. The density altitude is:
the altitude of the standard atmosphere on which the density is equal to the actual density of the atmosphere
Q11. The altimeter is fed by:
static pressure
Q12. 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.
Q13. When the barometric subscale of the altimeter is adjusted to 1013.2 hPa, what type of altitude is being measured?
Pressure altitude.

overread.
Q15. In case of accidental closing of an aircraft’s left static pressure port (rain, birds), the altimeter:
