The EASA
ATPL Instrumentation
test bank contains questions pertaining to
022-01-02 Gyroscopic 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
EASA ATPL
Written Test Prep Software and Apps. Not only is it more complete and up-to-date, but is also considerably faster and more efficient as a study tool.

- The fundamental difference between an INS and an IRS is that:
- The case of an air driven turn and balance indicator is leaking. A rate 1 turn of 360° will take:
- (Refer to figure 022-09)The attached diagram shows a gyro-stabilized platform. 1 is a .... gyro gimbal and 2 is a .... gyro gimbal.
- What indications should you get from the turn-and-slip indicator during taxi?
- An INS with the accelerometers aligned N/S and E/W is limited to use at latitudes below about 82° . This is because:
- Assume a perfectly frictionless DI is corrected to give zero drift on the ground at 30° N. The DI is set to read 270° in an aircraft tracking along the 60° parallel at a groundspeed of 545 knots. The DI reading after 80 minutes:
- Erection systems are provided for the purpose of:
- The heading information originating from the gyromagnetic compass flux valve is sent to the:
- The rotational speed of the gyroscope in a turn indicator falls below the correct operational speed. A 90° turn at an indicated RATE ONE on this turn indicator will take:
- An airborne instrument, equipped with a gyro with 1 degree of freedom and a horizontal spin axis is a:
- (Refer to figure 022-08)The diagram representing a left turn with insufficient rudder is:
- What is the main cause of precession?
- The operating principle of the pendulous vane unit erecting system is:
- Deviation compensation in a flux gate compass is done:
- When an aircraft has turned 90 degrees with a constant attitude and bank, the pilot observes the following on a classic artificial horizon:
- The errors of an INS fall into 3 categories:
- A Stand-by-horizon or emergency attitude indicator:
- The basic properties of a gyroscope are:The gyro's weightThe rigidity in spaceThe inertiaThe high RPMThe precessionThe combination of correct statements is:
- A standby artificial horizon must have the following properties:a remote gyroits own power supplyonly to be used in emergencyits own gyroone for each certified pilot
- When using an INS platform Coriolis affects:
- When, in flight, the needle and ball of a needle-and-ball indicator are on the left, the aircraft is:
- In a DGI what error is caused by the gyro movement relative to the earth?
- In order to align a strapdown inertial unit, it is requited to insert the local geographical coordinates. This is necessary to:
- Following 180° stabilized turn with a constant attitude and bank, the artificial horizon indicates:
- An aircraft is flying at a TAS of 270 knots. What AOB will give a rate 1 turn:
- What are the advantages of a laser gyro compared to a conventional gyro?
- The principle of operation of the turn and slip indicator is best described as:
- A gravity erector system is used to correct the errors on:
- The position accuracy of an RLG INS is:
- What is the maximum drift of a gyro, due to earth rate:
- An aircraft is flying along the 60° S parallel. After one hour the DI indication has increased by 21° . If the latitude nut of the DI has been set to zero drift on the ground at 30° S, the groundspeed of the aircraft is:
- When, in flight, the needle and ball of a needle-and-ball indicator are on the right, the aircraft is:
- In a left turn while taxiing, the correct indications are:
- The gimbal error of the directional gyro is due to the effect of:
- In the building principle of a gyroscope, the best efficiency is obtained through the concentration of the mass:
- Concerning the directional gyro indicator, the latitude at which the apparent wander is equal to 0 is:
- The forces which affect the balance ball in a turn and slip indicator are:
