The principle of the Schuler pendulum is used in the design of a:
In an inertial navigation system (INS), should the platform be displaced from the horizontal, it would oscillate with a period, called Schuler period, of about:
In order to align an IRS, it is required to insert the local geographical coordinates. This enables the IRS to: 1 - compare the computed latitude with the one entered by the pilot 2 - compare the computed longitude with the one entered by the pilot 3 - know the longitude. The combination that regroups all of the correct statements is:
In the directional gyro the detection system of the local vertical feeds:
The alignment sequence of an IRS consists of: 1 - searching for the local vertical 2 - searching for the true north 3 - searching for the latitude 4 - searching for the longitude 5 - comparison between the computed longitude and the one entered by the pilot 6 - comparison between the computed latitude and the one entered by the pilot. The combination that regroups all of the correct statements is:
If the static source of an altimeter becomes blocked during a descent the instrument will:
When flying in cold air (colder than standard atmosphere), the altimeter will:
The limits of the yellow scale of an airspeed indicator are:
An aeroplane is cruising at FL 220. The auto-throttle maintains a constant CAS. If the OAT decreases, the Mach number:
If the pilot increases the reference pressure using the sub-scale setting knob, the altitude indicated by the altimeter:
