If a flight crew sees volcanic activity, what do they need to advise in their report?

• A basic description of the volcanic activity

• Callsign, the location of the volcanic activity, and any associated weather conditions

• Callsign, location, air temperature and vertical extent of the ash cloud

• Callsign, position, time, altitude or flight level, location of activity observed, air temperature, spot wind and a brief description of vertical extent of ash cloud

State the latitudes where diurnal variation of pressure is the greatest?

• Polar Regions

• Mid Latitudes

• Equatorial Regions

• The same throughout the world

As an aircraft is cruising at the freezing level and crosses out of a cold front- What air will the aircraft be entering and where will the aircraft now be relative to the freezing level?

• Warmer air, Below the FZL

• Warmer air, Above the FZL

• Colder air, Below the FZL

• Colder air, Above the FZL

What does VCSH mean?

• Showers in the Vicinity

• Volcanic Ash

• Volcanic Showers

In regards to a STOL (Short takeoff and landing) aircraft, why is ice accretion less on the wings than on other surfaces such as propeller and ariels?

• Friction provides heating to bring the aircrafts wing temperature above 0ºc

• The stagnation point in front of the leading edge of the wing creates an area of high pressure which reduces ice accretion

• Aircraft cruise at lower speeds and altitudes

• There is a greater surface area for ice to accumulate onto

Under independent Cumulus clouds, what stability will the air have?

• Stable

• Unstable

• Conditionally Stable

• Inversion

How will Volcanic Ash affect an aircraft?

• Doesn't affect turbines

• Affects pistons and turbine engines the same

• Ash causes a blockage of airflow in a turbine causing flame out

• Flameout due to engine overheating

When is the SPCZ most active?

• Winter

• Summer

• When the ITCZ is active

• When the ITCZ is inactive

How is RVR measured on the runway?

• By the pilot reporting the amount of runway lights visible

• At three sensors along the runway (touchdown zone, mid stop, stop end)

• By an AWS placed at the aerodrome

Chose the correct statement below

• If the wind is northerly, ABCD will be a COL

• If the wind is southerly, ABCD will be a COL

• If the wind is westerly, A and B are toughs and C and D are ridges

• If the wind is easterly, A and B are toughs and C and D are ridges
