Q1. After landing at an aerodrome (aerodrome elevation 1715 FT), the altimeter indicates an altitude of 1310 FT. The altimeter is set to the pressure value of 1013 hPa. What is the QNH at this aerodrome?
1028 hPa.
Q2. What is the relationship, if any, between QFE and QNH at an airport situated 50 FT below sea level?
QFE is greater than QNH.
Q3. An aircraft lands at an airport (airport elevation 1240 FT, QNH 1008 hPa). The altimeter is set to 1013 hPa. The altimeter will indicate :
1375 FT.
Q4. What pressure is defined as QFE?
The pressure at field elevation
Q5. An aircraft is descending to land under IFR. If the local QNH is 1009 hPa, what will happen to the altitude reading when the altimeter is reset at the transition level ?
It will decrease
Q6. During the climb after takeoff, the altimeter setting is adjusted at the transition altitude. If the local QNH is 1023 hPa, what will happen to the altimeter reading during the resetting procedure ?
It will decrease
Q7. During the climb after takeoff, the altimeter setting is adjusted at the transition altitude. If the local QNH is 966 hPa, what will happen to the altimeter reading during the resetting procedure?
It will increase
Q8. An aircraft lands at an airport (airport elevation 540 FT, QNH 993 hPa) with the altimeter set to 1013 hPa. What will it indicate ?
1080 FT
Q9. After landing at an aerodrome (QNH 993 hPa) it is noticed that the altimeter is still set to 1013,2 hPa and that it reads 1200 feet. What is the elevation of the aerodrome above mean sea level ?
660 feet.
Q10. An altimeter adjusted to 1013 hPa indicates an altitude of 3600 FT. Should this altimeter be adjusted to the local QNH value of 991 hPa, the altitude indicated would be
3006 FT.
Q11. In Geneva, the local QNH is 994 hPa. The elevation of Geneva is 1411 FT. The QFE adjustment in Geneva is
942 hPa.
Q12. An aircraft is flying at FL 80. The local QNH is 1000 hPa. After the second altimeter has been adjusted to the local QNH, the reading will be approximately
7650 FT.
Q13. The barometric compensator of an altimeter is locked on reference 1013.2 hPa. The aircraft has to land on a point with an elevation of 290 feet where the QNH is 1023 hPa. Assuming that 1 hPa corresponds to 27 FT, the reading on the altimeter on the ground will be:
20 FT.
Q14. You must make an emergency landing at sea. The QNH of a field on a nearby island with an elevation of 4000 FT is 1025 hPa and the temperature is -20°C. What is your pressure altimeter reading when landing if 1025 hPa is set in the subscale?
Less than 0 FT
Q15. For a given airfield the QFE is 980 hPa and the QNH is 1000 hPa. The approximate elevation of the airfield is
160 metres
1hpa= 8m
Q16. Before landing, an altimeter set to QFE indicates
in standard atmosphere, the height of the aircraft above the official airport elevation.
Q17. What altimeter reading would you expect when landing at an airfield 3000 ft above MSL, altimeter setting is QFE for the field and local temperature is + 25°C?
0 ft.
Q18. You have landed on an airport (elevation 1240 ft, QNH 1008 hPa). Your altimeter subscale is erroneously set to 1013 hPa. Therefore, the indication will be:
1375 ft
Q19. You have landed on an airport (elevation 540 ft, QNH 993 hPa). Your altimeter subscale is erroneously set to 1013 hPa. Therefore, the indication will be:
1080 ft
Q20. Your altimeter indicates 3600 ft, while set to standard pressure. You now adjust the subscale to the local QNH of 991 hPa. What will the indication be?
3006 ft
Q21. When the barometric subscale of the altimeter is adjusted to 1013,2 hPa, what type of altitude is being measured?
Pressure altitude
Q22. You are departing an aerodrome (600 ft AMSL, QNH 1012 hPa) and proceed to another airfield (195 ft AMSL) with the same QNH. After landing, which barometric setting on the altimeter makes it again indicate 600 ft?
1027
Q23. An aircraft is in level flight at FL100 over a mountain range, which extends up to 2400 metres AMSL. If the regional QNH is 998 hPa, what is the approximate terrain clearance?
1636 feet
