Night VFR Quiz #1 - Airborne Aviation

Night VFR Quiz #1

This quiz is designed to test your knowledge of operations under the Night VFR.

Question 1

The published method of actuating pilot-activated airport lighting via the CTAF (AFRU + PAL) is:

Your calls to the CTAF will activate the lighting automatically

Three three-second pulses spaced at one second

Three one-second pulses spaced at one second

Each aerodrome with AFRU + PAL is different, refer to AIP ERSA

Refer to ERSA INTRO paragraph 23.

Question 2

The somatogravic illusion can result in fl ying into the ground on a night takeoff because:

acceleration is interpreted as the nose pitching up

acceleration is interpreted as the nose pitching down

rotation on takeoff is interpreted as a high nose attitude

the change of attitude with fl ap retraction is misinterpreted

Be sure to reference your instruments after take-off when visual ques are limited at night.

Question 3

When determining lowest safe altitude, unreported obstacles may exist in navigational tolerance areas up to a height of:

330 m

330 ft

360 m

360 ft

Refer to AIP GEN 3.2 paragraph 2.2.1

Question 4

An aircraft was flown under the VFR at night through an air distance of 150 nm since the last positive fix. During this time a failure of a normally available navaid occurred. In these circumstances, the pilot must ensure that the aircraft is not flown lower than 1000 ft above any terrain or obstacle within a circle, centred on the DR position, of:

10 nm radius

35 nm radius

50 nm radius

5 nm radius

20% of air distance + 5NM. Refer to AIP GEN 3.3 paragraph 3.7

Question 5

You are planning a private NVFR flight in G airspace of 110 minutes duration from YAAA to YBBB with a departure time of 0400Z. The aircraft has one VHF COM and no HF. First light at YBBB is 0605 and YBBB has no navigation aid but portable lighting with nobody in attendance. Your endurance from YAAA is 220 minutes and you have an alternate at YCCC with a navaid which is 45 minutes from YBBB and which has PAL lighting but no person in attendance. The flight can:

Proceed

Proceed only if YCCC has a person in attendance

Not proceed because the alternate requires an alternate due to lighting requirements

Not proceed because there is only one COM carried for PAL activation

There is sufficient fuel to hold at YBBB until first light or proceed to the alternate and arrive after first light.
Refer to AIP ENR 1.2 paragraph 1.1.2

Question 6

The end of daylight is defined as the time when the centre of the sun is:

10 degrees below the celestial horizon

10 degrees above the celestial horizon

6 degrees below the celestial horizon

6 degrees above the celestial horizon

This is defined as the end of evening civil twilight.

Question 7

A figure 43 on a terminal area chart (TAC) means that the Lowest Safe Altitude (LSALT) is:

4,300 ft within the grid plus including a buffer of 10 nm

4,300 ft on the published track

4,300 ft within the grid bounded by 4 degree of latitude and longitude

4,300 ft within the grid bounded by 1 degree of latitude and longitude

Refer to AIP GEN 3.3 paragraph 3.2

Question 8

What colour are taxiway edge lights?

Green

Blue

White

Yellow

Know your lights in the dark!

Question 9

An AFRU + PAL airport lighting system differs from a discrete frequency PAL system in that it:

Will not activate if the ambient light is above a preset level

Has no audible warnings on the activating frequency

Does not flash the windsock lights when about to time out

Must be activated within a total interval of 25 seconds

Question 10

An illusion where, on a dark night without background lighting, a point source of light appears to be moving is termed:

Somatogravic illusion

Hypsometric tinting

Autokinesis

Tunnel vision
