Question 1

A direct Mercator graticule is based on a projection that is:

Accepted Answer

Cylindrical

Answer

Spherical

Answer

Conical

Answer

Concentric

Question 2

A Lambert conformal conic projection, with two standard parallels:

Accepted Answer

The scale is only correct along the standard parallels

Answer

Shows all great circles as straight lines

Answer

Shows lines of longitude as parallel straight lines

Answer

The scale is only correct at parallel of origin

Question 3

Kepler's second law states that:

Accepted Answer

Each planet revolves so that the radius vector, sun to earth, sweeps out equal area in equal intervals of time

Answer

The area swept out by the radius vector of each planet, sun to earth, per hour, increasing with increasing length of the radius vector

Answer

Each planet moves in an elliptical orbit with the Sun at one focus.

Answer

The square of the orbital period is proportional to the cube of the semi-major axis.

Question 4

An island appears 30° to the left of the centre line on an airborne weather radar display. What is the true bearing of the aircraft from the island if at the time of observation the aircraft was on a magnetic heading of 276° with the magnetic variation 12°W?

Accepted Answer

054°

Answer

038°

Answer

234°

Answer

114°

Question 5

An aircraft was over 'A' at 1435 hours flying direct to 'B'. Given: Distance 'A' to 'B' 2900 NM True airspeed 470 kt, Mean wind component 'out' +55 kt, Mean wind component 'back' -75 kt, Safe endurance 9 HR 30 MIN. The distance from 'A' to the Point of Safe Return (PSR) 'A' is:

Accepted Answer

2141 NM

Answer

1759 NM

Answer

1611 NM

Answer

2844 NM

Question 6

An aircraft in the northern hemisphere is making an accurate rate one turn to the right. If the initial heading was 135°, after 30 seconds the direct reading magnetic compass should read:

Accepted Answer

More than 225°

Answer

225°

Answer

Less than 225°

Answer

More or less than 225° depending on the pendulous suspension used

Question 7

On a Lambert conformal conic chart the convergence of the meridians:

Accepted Answer

Is the same as earth convergency at the parallel of origin

Answer

Varies as the secant of the latitude

Answer

Is zero throughout the chart

Answer

Equals earth convergency at the standard parallels

Question 8

The angle between True North and Magnetic North is called:

Accepted Answer

Variation

Answer

Drift

Answer

Compass error

Answer

Deviation

Question 9

"Mean time" has been introduced in order to:

Accepted Answer

Introduced a constant measurement of time, independent of the daily variations in the movement of the Sun as observed from the Earth.

Answer

Compensate for the irregularities of the speed of rotation of the Earth around its axis.

Answer

Save energy as the problem of adjusting our watches entering every leap year is eliminated.

Answer

Have one fixed time to be used within the border of a country.

Question 10

On a lambert conformal chart the distance between two parallels of latitude having a difference of 2°, is measured to be 112mm. The distance between two meridians, spaced 2° longitude, is accordance to the chart 70 NM. What is the scale of the chart, in the middle of the square described?

1:1.984.000

Answer

1:1.056.000

Answer

1:1.233.000

Answer

1:756.000
