From BOD at CALOUNDRA to EOD ALICE SPRINGS the amount of daylight available is …

Answer 5

14 hours 34 minutes

Part 61 MOS Schedule 3 - 2.2 CNVC - BOD and EOD

Question 6

The CTA steps are centred on aerodrome A
The aircraft is at position X maintaining 2000 ft AMSL
Climbing GS 120 kt.

If controlled airspace is to be avoided (remain OCTA), for a planned cruise altitude of A075, and a continuous 800 ft/min rate of climb on track, the earliest distance from departure for the climb to commence, and the gradient of climb achieved, are closest to …

Answer 6

40 nm and 6.66%

Part 61 MOS Schedule 3 - 2.4 CNVC - Climb Gradients

Question 7

You are conducting a flight from HAMILTON ISLAND to AYERS ROCK.

Beginning of daylight HAMILTON ISLAND (20 22S 148 57E) is 0600 LMT.
End of daylight AYERS ROCK (25 11S 130 58E) is 1805 LMT.

You plan to land 30 minutes before end of daylight at AYERS ROCK.

The daylight available for this flight is closest to …

Answer 7

12 hour 47 minutes

Question 8

The CTA steps are centred on A.
The aircraft is at position X maintaining 2500 ft AMSL OCTA.
Climbing ground speed is 130 kt.

Ignoring the navigational tolerance, to avoid controlled airspace (remain OCTA), the maximum continuous rate of climb (in whole feet) for a climb on track to cruise at A085, commencing at 30 nm from departure is …

Answer 8

between 370 fpm and 390 fpm

Part 61 MOS Schedule 3 - 2.4 CNVC - ROC

Question 9

Two adjacent WAC charts can never be joined North to South because …

Answer 9

the charts have different standard parallels
