CPL Nav Progress Test 04

Define a great circle

• Its plane passes through the centre of the Earth

• All parallels of longitude

• All meridians on latitude

• Cuts all meridians at a constant angle

Define the prime meridian

• The point where NZDT or NZST is measured

• Passes through 0°E/W and 180°E/W

• A datum for time which changes position depending on the season

• The meridian passing through Greenwich

What kind of line is this?

• Great circle

• Small circle

• Rhumb line

• Converging line

True or Flase

Bearing to the station is found by adding heading to relative bearing in an anticlockwise direction.

• False

• True

What is a caution when deriving distance from a chart?

• Distances change over the chart and therefore the distances are always slightly inaccurate

• Using the right side of the nav ruler depending on what the chart scale is

• Ensuring that everything is in km when making a flight plan

• That variation is accounted for when converting nm to sm

Select the true statement

• Distance is measured in nm, altitude is measured in feet, visibility is measured in m or km and runways are measured in m.

• Distance is measured in sm, altitude is measured in hectopascals, visibility is measured in km and runways are measured in m.

• Distance is measured in sm, altitude is measured in feet, visibility is measured in m or km and runways are measured in km.

• Distance is measured in nm, altitude is measured in feet, visibility is measured in quartz and runways are measured in km.

What is the distance between West Melton aerodrome and flags on this 1: 250,000 chart?

• 20nm

• 10nm

• 30nm

• 20km

Define true airspeed

• EAS corrected for density error

• CAS correct for density error

• EAS corrected for drift error

• EAS corrected for dilution error

If an aircraft fly's a constant IAS from a cold area into a warm area TAS will?

• Increase

• Decrease

• Stay the same as you haven't climbed or descended

• Decrease initially then increase

If you maintain a constant TAS in a descent what will happen to IAS?

• Increases

• Decreases

• Remains unchanged

• Becomes innacurate
