Gnav 551-600

You are heading 345° (M), the variat ion is 20°E, and you take a radar bearing of 30° left of the nose from an island. What bearing do you plot?

• 160° (T)

• 155° (T)

• 140° (T)

• 180° (T)

A useful method of a pilot resolving, during a visual flight, any uncertainty in the aircraft's position is to maintain visual contact with the ground and:

• set heading towards a line feature such as a coastline, motorway, river or railway.

• fly the reverse of the heading being flown prior to becoming uncertain until a pinpoint is obtained.

• fly expanding circles until a pinpoint is obtained.

• fly reverse headings and associated timings until the point of departure is regained.

What is the average TAS climbing from 1 500 ft up to FL180, given a temperature ISA +15°C, a CAS 230 kts and QNH 1032?

• 263 kts

• 283 kts

• 270 kts

• 309 kts

A ground feature was observed on a relative bearing of 325° and five minutes later on a relative bearing of 280°. The aircraft heading was 165°(M), variation 25°W, drift 10° Right and GS 360 kts. When the relative bearing was 280°, the distance and true bearing of the aircraft from the feature was:

• 30 NM; 240°.

• 40 NM; 110°.

• 40 NM; 290°.

• 30 NM; 060°.

Given: Aircraft height: 2 500 ft ILS GP: angle 3° At what approximate distance from THR can you expect to capture the GP?

• 14.5 NM

• 7.0 NM

• 13.1 NM

• 8.3 NM

Given: Distance A to B: 415 NM Planned GS: 295 kts ATD: 1000 UTC At 10:20 UTC fix is obtained 110 NM along track. What GS must be maintained from the fix in order to achieve planned ETA at B?

• 320 kts

• 268 kts

• 295 kts

• 286 kts

Given: Distance A to B: 90 NM Fix obtained 60 NM along and 4 NM to the right of course. What heading alteration must be made to reach B?

• 4° left.

• 16° left.

• 12° left .

• 8° left.

During visual navigation in freezing conditions, after heavy snowfall, which of the following landmark will give the best reference for a visual checkpoint:

• an electrical line.

• a large river.

• a railway.

• a country road.

Transferring range position lines, you should:

• always plot the original position line as well as the transferred range position line.

• transfer the origin and plot the range position lines from the transferred origin.

• never transfer the origin (DME station).

• include at least 1 straight position line.

An aircraft at FL310, M 0.83, temperature -30°C, is required to reduce speed in order to cross a reporting point five minutes later than planned. Assuming that a zero wind component remains unchanged, when 360 NM from the reporting point Mach number should be reduced to:

• M 0.76

• M 0.74

• M 0.78

• M 0.80
