ABNORMAL HANDLING
Hawker 800XP Pro Line 21
Section V - FLIGHT HANDLING
These additional lessons are:
• Recognition is difficult and is usually complicated by marginal weather.
• Time available for recognition and recovery is short (as little as 5 seconds).
• Aircrew co-ordination is essential for prompt windshear recognition and recovery.
• Flight path must be controlled with pitch attitude (unusual stick forces may be required) and lower
than normal airspeed may have to be accepted.
STANDARD OPERATING TECHNIQUES
A series of recommendations were formulated under the general heading of Standard Operating
Techniques (SOTs).
Having evaluated the weather, the flow chart recommends the aircrew follow SOTs in an effort to aid
them with the early recognition of a windshear encounter.
The SOTs fall into two general headings of air crew awareness and air crew co-ordination.
The aircrew should be prepared to change to windshear recovery techniques as soon as the SOTs
indicate the likelihood of windshear activity.
Evaluate the Weather
In most windshear related accidents that occur, several potential windshear indicators have been
present.
Windshear indicators are meant to be cumulative.
The more indicators present, the more crews should consider delaying departure or approach.
The weather evaluation process must continue during the takeoff and climb-out and throughout the
approach and landing.
The following weather information should be examined for any potential windshear conditions affecting
the flight:
• Terminal Area Forecasts
• Hourly Sequence Reports
• Severe Weather Watch Reports
• LLWAS (Low Level Windshear Alert System) Reports
• SIGMETS (Significant Meteorological Information).
• PIREPS (Pilots Reports) or AIREP SPECIAL (Special Aircraft Observation).
• Airborne Weather Radar
• Visual clues from the flight compartment.
