test bank contains questions pertaining to
. 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
JAA ATPL Theory Test Prep Software
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
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.

- An aircraft is flying through the Alps on a warm summers day. The weather is fine, and there is a high pressure system in the area. During the flight, a mountain is passed at an altitude of its summit. What reading will the aneroid altimeter give, compared to the summits elevation?
- The QNH at an airfield located 0 metres above sea level is 1022 hPa. The air temperature is not available. What is the QFF?
- What happens to an aircrafts altimeter on the ground at the approach of a cold front?
- Which statement is true?
- The QNH of an airport at sea level is 983 hPa and the temperature deviation from ISA is -15° C below FL 100.What is the true altitude of FL 100?
- You have landed at an airport, local QNH 993 hPa. After landing, you notice, that your altimeter subscale is still set to 1013,2 hPa. Your altimeter indicates 1200 ft. What is the airport elevation?
- In which of the following cases will the altimeter always indicate the airport elevation when landing?
- You are flying from Madrid (QNH 1012) to Paris (QNH 1015) at FL 80. If your true altitude and indicated altitude remain the same then...

- Suppose that you want your altimeter on landing to indicate airport elevation. Which of the following pressures will you use as reference?
- What is density altitude?
- During a flight at FL 100 from Marseille (QNH 1012 hPa) to Palma de Mallorca (QNH 1015 hPa), an aircraft remains at a constant true altitude. The reason for this is that:
- What information is required to convert a minimum safe altitude into a lowest usable flight level?
- An aircraft, flying so that the altimeter indicates 2500 ft with the current regional QNH set in the subscale, is flying towards an area of lower pressure. If the pilot fails to revise the subscale setting as the QNH changes, then the aircraft will:
- QNH is defined as:
- Suppose that you are flying at FL 40 and that you reset the altimeter to reference pressure 993 hPa. The altimeter then indicates:
- The QNH at an airfield 200m AMSL is 1009 hPa, air temperature is 10 C lower than standard. What is the QFF?
- 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?
- An aircraft is flying over the sea at FL 120, with a true altitude of 12.000 feet, local QNH is 1013 hPa. What assumption, if any, can be made about the air mass in which the aircraft is flying?
- At an airport (200 m AMSL), a QNH of 1009 hPa and a temperature 10° C lower than ISA is observed:
- The difference between QNH and QFE at an airport is:
- Which of the following conditions gives the highest value of the QNH?

- Which of the following statements is true?
- An aircraft is flying at FL 180 on the northern hemisphere with a crosswind from the left. Which of the following is correct concerning its true altitude?
- Which factors below increase density altitude for a given aerodrome:Decreasing air pressure.Increasing air pressure.Decreasing temperature.Increasing temperature.
- At an airport (400 m AMSL), a QFF of 1016 hPa and a temperature 10° C higher than ISA is observed:
- At an airport 1.700 ft above sea level the temperature reading is +10° C . from the barometer readings made at the same time QFE, QFF and QNH are computed. Which of the following statements concerning air pressure in correct?
- An aircraft is flying at FL 75 over point A where the QNH is 1013mb, en-route to B where the QNH is 979mb.Assuming that 1mb = 30ft and that the elevation of B is 823 metres, the terrain clearance over B is:
- In order to reduce QFE to QNH, which of the following item(s) must be known?
