The JAA
ATPL Meteorology
test bank contains questions pertaining to
050-01-06 Altimetry
. The following list contains only a relatively small percentage of the pertinent
questions. Our software, which you are free to download now at no cost, will
generally contain a much more complete set of questions associated with this
test bank. This list is intended only to familiarize you in a general way with
the questions of the
Meteorology
test bank.

That said, while the following questions are intended
as a general familiarization tool, this list may not be up-to-date nor accurate.
We do not update this website as often as we update our software, which will
contain at any moment all questions that we have for a given test / topic. Therefore,
if you need to actually study for your test, instead of using the list below,
we strongly, strongly encourage you to download our GroundSchool
JAA ATPL
written test prep software. Not only is it more complete and up-to-date, but is also considerably faster and more efficient as a study tool.

- You are flying at a constant altitude according to your altimeter. Your altimeter setting is unchanged. Which of the following interact to give a minimum a true altitude?Flying from an area of low pressure to that an area of high pressure.Flying from an area of high pressure to that an area of low pressure.1,Flying from a warm air mass to a cold air mass.Flying from a cold air mass to a warm air mass.
- 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 1.200 feet. What is the elevation of the aerodrome above mean sea level?
- An aircraft is flying at FL 75 over point A where the QNH is 1013 hPa, enroute to B where the QNG is 979 hPa.Assuming that 1hPa equals 30 ft and that point B is 823 metres amsl the terrain clearance over B is:
- 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?
- You are flying over an airport at an indicated altitude of 5.600 ft. Airport elevation = 2.785 ft. The altimeter is set at the correct aerodrome QNH value of 993 hPa and the instrument error is zero, you are crossing the airport at a height above ground of:(standard pressure setting = 1013 hPa, 1 hPa = 30 ft)
- 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?
- At an airport in California (69 m below MSL), a QNH of 1018 hPa and a temperature 10° C higher than standard is observed:
- What is the relationship between QFE and QNH at an airport 50ft below MSL?
- A vertical spacing of 1000 FT, is the standard required separation between two FL. Under conditions of cold air advection (ISA -15° C), what would the true vertical separation be?
- Which value has to be known to calculate the QNH out of the QFE?
- Which of these would cause your true altitude to decrease with a constant indicated altitude?
- QNH 1025 hPa at an altitude of 200 m AMSL: What will the approximate QFE be?
- An aircraft is flying through the Alps on a very cold winters day. The regional QNH is 1013 hPa. During the flight, you circle around a mountain at an altitude of its summit. What reading will the aneroid altimeter give, compared to the elevation of the summit?
- You are flying from Marseilles (QNH 1012 hPa) to Palma de Mallorca (QNH 1012 hPa) at FL100. You notice that the effective height above MSL (Radio Altitude) increases constantly. Hence.
- Flying from Marseilles (QNH 1012) to Palma (QNH 1015) at FL100. You do not reset the altimeter, why would true altitude be the same throughout the flight?
- On takeoff, your altimeter is set to the local QNH of 1023 hPa. While passing the Transition Altitude, you adjust the subscale accordingly:
- The pressure altitude is equal to the true altitude if:
- An aircraft is to fly at an indicated altitude of 5000 ft from X( elevation 850 ft, QNH 984 hPa) to Y (elevation 2300 ft QNH 1024 hPa). Assuming that the altimeter sub-scale is set to 984 mb and 1 hPa=30 ft, the height of the aircraft over X and Y will be:
- 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:
- If atmospheric conditions exist such that the temperature deviation is ISA 10° C in the lower troposphere up to 18000 FT, what is the actual layer thickness between FL 60 and FL 120?
- 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?
- You intend to overfly a mountain range. The recommended minimum flight altitude is, according to the aviation chart, 15000 FT/AMSL. The air mass that you will fly through is on average 15° C warmer than the standard atmosphere. The altimeter is set to QNH (1023 hPa). At what altimeter reading will you effectively be at the recommended minimum flight altitude?
- QFE 1000 hPa at an altitude of 200 m AMSL. What will the approximate QNH be?
- When the subscale is set to the QNH of an airfield the pressure altimeter indicates:
- 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?
- What is absolute altitude?
- The definition of QNE is:
- If the aircraft had over-shot from Doha having used a QFE of 1000mb and then landed at Al Ain, again without re-setting the altimeter what would it read on touch-down?
