122) The validity period of a flight track system organized in MNPS (Minimum Navigation Performance Specification) airspace during a Westbound flight normally is :

129) You plan to fly from point A (60°N 010°E) to point B (60°N 020°E). The gyro North of the gyro compass, assumed to be operating perfectly, with no rate correction device, is aligned with the true North of point A. The constant gyro heading to be followed when starting from A given that the flight time scheduled is 1h30 min with a zero wind, is equal to :

94) During a transoceanic and polar flight, the transport precession is the rotation in degrees of the gyro North with respect to the:

96) (For this question use annex 071-2070A) On the diagram where : Nt = True North Nm = Magnetic North Ng = Grid North If the magnetic variation is equal to 65°W and if the grid variation is equal to 4°E, the correct arrangement of the different north is :

At 18h40min UTC, a complete failure of the inertial systems of an aircraft flying on the LONDONANCHORAGE line occurs in the geographic North pole region. The wind is nil, the grid heading at this moment is 315°. The crew then uses the Sun to continue the flight. The bearing of the Sun on occurence of the failure is : NOTE: The time equation is nil. The chart used is a polar stereographic chart whose grid is parallel with the zero meridian, the Grid North is in direction of the geographic North pole.

) If both precision navigation systems of an aircraft are unserviceable during a flight in MNPS airspace, and if you cannot establish communication with the air traffic control, you :

151) In a polar Antarctic regions, the pilot uses a South polar stereographic chart whose printed over grid is parallel with the zero meridian and Grid North in the direction of geographic North along this meridian. The aircraft position is 80°S 130°E, its true route is 110°, the grid route at this moment is

25) A pilot is using a polar stereographic chart whose grid is parallel to the zero meridian, with Grid North in the direction of the North geographic pole. In polar regions, the pilot stops navigation in free-gyro mode after leaving the 6 microteslas zone, and the grid heading controlled by information from the inertial navigation system (INS) is 045°. After switching to "magnetic mode", the compass heading is 220°. The INS position at this moment is 76°N 180°W. The magnetic variation on the chart is 10°E. The compass shift on this heading at this point in time is:

3) During a flight to Europe, planned in MNPS (Minimum Navigation Performance Specification) airspace, you expect to cross the 30°W meridian at 11H00 UTC ; you will then normally be :

12) The MNPS (Minimum Navigation Performance Specification) airspace extends vertically between flight levels:

In the event of a contingency which required an en-route diversion to an alternate aerodrome across the direction of the prevailing "NAT" traffic flow and if prior ATC clearance cannot be obtained an aircraft not able to maintain its assigned flight level should:

46) In the event of a contingency which required an en-route diversion to an alternate aerodrome across the direction of the prevailing "NAT" traffic flow and if prior ATC clearance cannot be obtained an aircraft able to maintain its assigned flight level should:

69) The chart in question is of the polar stereographic type with its grid parallel to the zero meridian, and Grid North in the direction of the North geographic pole. The gyro does not comprise a rate correction device. The gyro-magnetic compass of an aircraft standing at an aerodrome located at 59°57'N 010°30'E is switched to free gyro mode at 14.00 UTC, with gyro North being aligned with Grid North and the gyro heading reading 120°. A technical problem delays take off until 16.30 UTC. The gyro, whose mechanical precession is zero, was not reset prior to take off. The err
