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
18- How you monitor glidepath if you encounter windshield for landing?
- Use ILS or VASI
19- When you have to be stabilized on the approach during a landing windshear?
- No later than 1,000 ft AGL
20- What you have to consider related to thrust during a landing windshear?
- Minimized thrust reductions.
21- How you obtain positive terrain separation during a takeoff windshear?
- Flight at intermittent stick shaker may be needed
- Use smooth , steady controls to avoid a pitch attitude overshoot and stall
22- What you do if you get CAUTION + “Monitor Radar Display” before V1?
- DELAY or REJECT TAKEOFF
23- What you do if you get CAUTION + “Monitor Radar Display” above V1?
- Maneuver as required to avoid windshear
- Consider using maximum thrust
24- What you do if you get WARNING + “WINDSHEAR AHEAD, WINDSHEAR AHEAD” before V1?
- DELAY or REJECT TAKEOFF
25- What you do if you get WARNING + “WINDSHEAR AHEAD, WINDSHEAR AHEAD” above V1?
- Perform the WINDSHEAR ESCAPE MANEUVER
26- What you do if you get WARNING + “WINDSHEAR, WINDSHEAR, WINDSHEAR” (Reactive) before V1?
- DELAY or REJECT TAKEOFF
27-What you do if you get WARNING + “WINDSHEAR, WINDSHEAR, WINDSHEAR”(Reactive) above V1?
- Perform the WINDSHEAR ESCAPE MANEUVER
28- What you do if you get Unacceptable Airspeed Deviations before V1?
- REJECT TAKEOFF
29- What you do if you get Unacceptable Airspeed Deviations above V1?
- Perform the WINDSHEAR ESCAPE MANEUVER
- At Vr, normal rotation to 15 degrees no later than 2,000 ft of runway remaining
30- What you do if you get CAUTION + “Monitor Radar Display” during approach?
- Continue the approach if able to avoid windshear, or
- GO-AROUND and maneuver to avoid windshear
31- What you do if you get WARNING + “WINDSHEAR AHEAD, WINDSHEAR AHEAD” during approach?
Perform either:
- GO-AROUND, OR
- WINDSHEAR ESCAPE MANEUVER
32- What you do if you get WARNING + “WINDSHEAR, WINDSHEAR, WINDSHEAR “ (Reactive) during approach?
- Perform the WINDSHEAR ESCAPE MANEUVER
33- What you do if you get Unacceptable Airspeed or Flight Path Deviations during approach?
- Perform the WINDSHEAR ESCAPE MANEUVER
34- When the CAUTION + “Monitor Radar Display” is inhibited during takeoff?
- From 80 kts to 400 ft (RA)
35- When the WARNING + “WINDSHEAR AHEAD, WINDSHEAR AHEAD” is inhibited during takeoff?
- From 100 kts to 50 ft (RA)
36- When the is WARNING + “WINDSHEAR, WINDSHEAR, WINDSHEAR” (Reactive) inhibited during takeoff?
- Until rotation
37- Define Reactive Windshear System (RWS)?
- It is when the system identify the aircraft is in an actual windshear situation.
38- When the CAUTION + “Monitor Radar Display” is inhibited during approach?
- Bellow 400 ft (RA)
39- When the is the GO-AROUND, WINDSHEAR AHEAD inhibited during approach?
- Bellow 50 ft (RA)
40- What could be good examples of unacceptable flight path deviations bellow 1,000 ft AGL?
1- Greater than 15 kts indicated airspeed
2- 500 fpm vertical speed
3- 5 degrees pitch attitude
4- 1 dot displacement from glideslope
5- Unusual thrust lever position for a significant period of time
41- What is the immediate callout after encountering windshear?
- ESCAPE, MY AIRCRAFT
42- What are the actions required by the profile to escape windshear?
- Disengage the autopilot and push TOGA
- Apply Maximum thrust
