FLIGHT PROCEDURES-- Runway Veer-- Off

What is Runway Veer-off??

Runway veer-off is runway excursion in which an aircraft departs the side of the runway during take-off or landing.

 What factors contribute to a runway veer-off??

a. WEATHER

b. CREW TECHNIQUE/DECISION

c. AIRCRAFT SYSTEMS

WEATHER

Runway Condition, Wet or Contaminated, Severe Wind, Cross wind , Windshear, Reverse thrust effect in a crosswind

and on Wet/Contaminated runway

CREW TECHNIQUE/DECISION

Use on Nose Wheel Steering at higher speeds

Airspeed too fast on runway to exit

Incorrect Cross wind landing technique--- a) Drifting during transition from a wings level crosswind approach(crabbed approach) to a steady-sideslip crosswind approach ,or failing to transition from a wings level approach to a steady-sideslip approach(decrab) in strong crosswind conditions.

AIRCRAFT SYSTEMS

• Asymmetric thrust

• Non-deployment of speed brakes • Uncommanded differential braking

The runway veer-off is usually a result of one or more of above factors.

Following the company promulgated procedures, limitations, techniques; etc. will help in mitigating or managing the excursions.
