Section V - FLIGHT HANDLING
Avoid Known Windshear
The importance of avoiding severe windshear and microbursts cannot be over-emphasized.
Microburst windshears exist which are beyond the capability of even the largest of airplanes and the
most highly skilled pilots. Avoidance may only mean a ten to twenty minute delay.
A summary of the weather evaluation factors which can be helpful in avoiding windshear is provided by
the following information:
Presence Of Convective Weather Near Intended Flight Path
Observation Windshear Probability
• With localized strong winds:
Tower reports, or observed dust rings, tornado-like features, etc....................... HIGH
• With heavy precipitation:
Observed or radar indications of contour, red or attenuation shadow ................ HIGH
• With rainshower .................................................................................................. MEDIUM
• With virga ............................................................................................................ MEDIUM
• With lightning....................................................................................................... MEDIUM
• With moderate or greater turbulence:
Reported or radar indications.............................................................................. MEDIUM
• With temperature/dew point spread between -1
°
C and 10
°
C (30
°
and 50
°
F) .. MEDIUM
• ONBOARD WINDSHEAR DETECTION SYSTEM ALERT (If Installed)
Reported or observed ......................................................................................... HIGH
PIREP or AIREP SPECIAL of an Airspeed loss or gain
• 15 knots or greater .............................................................................................. HIGH
• Less than 15 knots .............................................................................................. MEDIUM
LLWAS ALERT/WIND Velocity Change
• 20 knots or greater .............................................................................................. HIGH
• Less than 20 knots .............................................................................................. MEDIUM
• Forecast of Convective Weather ......................................................................... LOW
