Ops. Reg. Section 10

What is meant by "Low Altitude Windshear"?

• A sudden change in wind velocity on the runway, final approach or in the climb-out

• An anticipated wind change on the apron

Vertical windshear causes the aircraft’s airspeed to increase or increase during the climb/descent due to the:

• Horizontal wind component in the vertical-axis

• Horizontal wind component in the horizontal-axis

• Vertical wind component in the vertical-axis

• Vertical wind component in the horizontal-axis

Indication of windshear on final by a deviation of airspeed and altitude of

• 5kts / 250ft

• 15kts / 500ft

• 20kts

• 25kts

What can you expect with a microburst on finals? (Ops Figure 11-4, C)

• increase headwind, down draught, increase tailwind

• increase tailwind, down draught, increase headwind

• sudden wind changes. Tailwind then headwind

• sudden changes. Headwind the tailwind

[255/256] What is the definition of updraught?

• wind vector with positive vertical (component/velocity)

• Wind Vector with negative vertical

• Horizontal wind shear

• Vertical wind column

What conditions can you use to recognize low level windshear?

• Heavy rain and reduced visibility

• Sudden speed change and turbulence

• Turbulence with increasing visibility (CAT)

• Thunderstorm and lightning

When experiencing a windshear after take-off, what should the pilot do?

• Maintain or apply maximum thrust

• Accelerate to the maximum speeds for flaps extended

• Retract landing gears and flaps to reduce drag

• Turn away from the area of the windshear

When there is windshear reported for take-off (Ops 11.4.4)

• Consider to postpone the take-off

• Carry on with take-off if it is within aircraft limits

• Inform ATC

• Let the PIC decide what to do

Possible windshear reported before departure:

• delay take-off, select maximum available thrust, use longest possible runway, least possible flaps

• Max take-off thrust, least possible take-off flaps

• delay take-off, select maximum available thrust, use longest possible runway, consider using higher rotate speed

• Max take-off thrust, delay rotation

When you have a big downburst of wind on approach what should you do? (Ops 11.4.3)

• Go around

• Apply appropriate windshear manoeuvre
