wind shear

#1. Take-off EPR is being delivered by all engines and the take-off is proceeding normally, the undercarriage has just retracted. Which initial indications may be observed when a headwind shears to a downdraught?

• AIndicated Air Speed: constant. Vertical Speed: decreases. Pitch Attitude: decreases.
• BIndicated Air Speed: increases. Vertical Speed: decreases. Pitch Attitude: constant.
• CIndicated Air Speed: decreases. Vertical Speed: constant. Pitch attitude: constant.
• DIndicated Air Speed: decreases. Vertical Speed: decreases. Pitch Attitude: decreases.

#5. Which wind-shear condition results in a loss of airspeed?

• ADecreasing headwind or tailwind.
• BIncreasing headwind and decreasing tailwind.
• CDecreasing headwind and increasing tailwind.
• DIncreasing headwind or tailwind.

#7. Which condition would INITIALLY cause the indicated airspeed and pitch to increase and the sink rate to decrease?

• ATailwind which suddenly increases in velocity
• BSudden decrease in a headwind component.
• CSudden increase in a headwind component.
• DCalm wind which suddenly shears to a tailwind
