The JAA
ATPL Instrumentation
test bank contains questions pertaining to
022-01-01 Air Data Instruments
. 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
Instrumentation
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.

- The static pressure error of the static vent on which the altimeter is connected varies substantially with the:
- The altitude indicated on board an aircraft flying in an atmosphere where all atmosphere layers below the aircraft are warm is:
- During a missed approach and go-around procedure the change of aircraft attitude plus raising of the landing gear and changing of flap settings can cause short term unpredictable errors in certain instruments. The instruments most likely to be affected in this case are:
- The advantages of an ADC over a traditional pitot - static system are:position and compressibility correction.reduced lagability to supply many instrumentsability to act as an altimeter following failure.
- An is aircraft flying at a TAS of 1100 knots at FL 650. A change in 0.1M causes a change in TAS of 57 knots.The temperature deviation at FL 650 assuming an ISA atmosphere is:
- How many diaphragms are present in a basic Mach meter?
- The purpose of the IVSI is to:
- Indication of Mach number is obtained from:
- The errors to which the machmeter is subject are:
- The QNH is by definition the value of the:
- What is the significance of the yellow arc in an airspeed indicator?
- With a constant weight, irrespective of the airfield altitude, an aircraft always takes off at the same:
- VLE is the maximum:
- When flying from a sector of warm air into one of colder air, the altimeter will:
- An aircraft is flying at 0.86 M, temperature 218 Kelvin. The TAS is:
- An aircraft is flying at FL 390, temperature -56.5° C at Mach 0.85. The TAS of the aircraft is:
- Sound propagates through the air at a speed which only depends on:
- If the outside temperature at 35 000 feet is -40° C, the local speed of sound is:
- If the ambient temperature decreases, the TAS of an aircraft cruising at a constant Mach number will:
- VSO is shown on an ASI by a:
- For an altimeter, pressure fluctuations at the static vent cause:
- In the IVSI, lag error:
- A temperature sensor having a recovery factor of 0.75 indicates 30° C. Static Air Temperature (SAT) is 25° C.How high is the Ram-rise?
- An increase of 0.15 Mach results in an increase of 93 kt TAS of an aircraft. The local speed of sound is:
- Match true airspeed (TAS) with the associated definition:
- In An Air Data Computer (ADC), aeroplane altitude is calculated from:
- If the alternate static source is selected, the greatest error in the machmeter will be:
- The ISA temperature and pressure for 18 000 ft are:
- The Total Air Temperature probe measures total temperature (TAT) by:(SAT = Static Air Temperature)
- The possibility of ingress of moisture to the instruments:
- The vertical speed indicator indications may be in error for some seconds after starting or finishing a climb or descent. The error is a result of:
- The vertical speed indicator of an aircraft flying at a true airspeed of 100 kt, in a descent with a slope of 3° indicates:
- The Mach number is a function of the:
- The hysteresis error of an altimeter varies substantially with the:
- The vertical speed indicator VSI is fed by:
- Compressibility Error requires a .... (i) correction because it is .... (ii) of ....(iii) pressure. It gives .... (iv):
- During a straight and uniform climb, the pilot maintains a constant calibrated airspeed (CAS):
