8) Windshear Flashcards
1- Define Predictive Windshear System (PWS)?
- It is a System that predicts windshear events in the proximity of the aircraft.
2-How the PWS works?
- It generates Caution or Warning alerts to predict windshear events in the proximity of the aircraft.
3- What is the difference between Caution or Warning PWS alert?
- A WARNING predicts an event that is closer to the aircraft than a CAUTION alert.
4- How you avoid a windshear?
- Use judgement to evaluate the weather and take the decision.
- If Does NOT look good, DON’T GO!!!!!!
5- Normally, how long a windshear event last?
- An average windshear last only 10-15 minutes
6- What kind of windshear can you expect with any hazardous convective weather within 15 miles of airport?
- High Windshear likely
- Medium Windshear possible
- Low Windshear unlikely
7- What is the right judgement for HIGH Windshear event?
- Delaying or Diverting is recommended
8- What is the right judgement for Medium Windshear event?
- Use appropriate precautions
9- What is the right judgement for Low Windshear event?
- Use appropriate precautions
10- How you identify a windshear?
1- Pilot Reports of winshear or turbulence
2- Low-level windshear Alerts
3- Weather Reports including thunderstorms and Virga
4- Avoid areas of severe weather
11- How you identify areas of severe windshear?
- Airspeeds changes greater than 15 kts.
12- What takeoff flap setting is recommended for windshear?
- Flaps 5-15
- 737 MAX : Flaps 5/10/15
13- What thrust setting is recommended for windshear at takeoff?
- 26K or 27K if planned
- 737 MAX : TO thrust
14- What runway is prefer for windshear for takeoff?
- Longest suitable runway
15- What adjust to Vr is recommended for windshear at takeoff?
- Vr increase to performance limited gross weight rotation speed.
16- What Flap setting is recommended when you are expecting windshear for landing?
- Flaps 30, consistent with field length
17- What runway is prefer for windshear for landing?
- Longest suitable runway
