Ops. Reg. Section 11

aircraft are classified based on speeds at the threshold by:

• TAS times 1.3VSO

• IAS times 1.3VS1G at landing config

• IAS times 1.5VSO

• IAS = 1.23VS1G at landing config

Wake vortex turbulence is correctly defined as: (Ops 12.1.1):

• The displaced air in the wake of the passage of an aircraft

• The effect of the rotating air masses generated behind the wing tips of all aeroplanes

• The efflux from jet engines and the wash from propellers.

• ‘Dirty’ air caused by the horizontal movement of an aeroplane through the atmosphere.

The strongest vortices are generated by

• Heavy aeroplanes, travelling fast, in a ‘clean’ configuration

• Heavy aeroplanes, travelling fast, in a ‘dirty’ configuration

• Heavy aeroplanes, travelling slow, in a ‘clean’ configuration

• Heavy aeroplanes, travelling slow, in a ‘dirty’ configuration

Wake turbulence vortex on the runway is the worst in the following conditions:

• Strong crosswind

• Light crosswind

• Strong tailwind

• Light headwind

Worst wake turbulence

• light crosswind

• no wind

How many minutes between light and medium aircraft departing? (Ops Figure 12-2)

• 2 mins

• 3 mins

• 4 mins

• 5 mins

Medium/light take off behind heavy from intermediate runway (new 235/236)

• 2 min

• 3 min

Wake turbulence non-radar separation 2mins is for?

• Medium landing behind heavy

• Light landing behind medium

According to ICAO DOC 4444, a wake turbulence non-radar separation minima of 2 minutes shall be applied is:

• LIGHT aircraft taking off behind a MEDIUM aircraft from an intermediate part of the same runway

• MEDIUM aircraft taking off behind a HEAVY aircraft from an intermediate part of a parallel runway separated by less than 760m

• LIGHT aircraft landing behind a MEDIUM aircraft

• MEDIUM aircraft landing behind a HEAVY aircraft

In a non radar environment, what is the separation required for a light/medium aircraft taking off behind a heavy aircraft on a cross runway? (Triangle runway above is attached to this question)

• 1min

• 2min

• 2.5min

• 3min
