Common Terms and Definitions Group Braking Action Reports
Mission Statement: Develop common definitions for pilot braking reports of Good/Fair(Medium)/Poor/Nil. Develop common guidelines for flight crew assessment of braking action conditions (how to take and report) • Pirep to be made independent of runway length, aircraft type, crew experience • Come up with a way to “un-nil” a runway • Identify criteria that describes unsafe operations • Standardize terminology with ICAO
Proposed Metrics for Pilot Observations • Thrust Reverser Use • Directional Control • Anti Skid cycling • Brake pedal force used • Deceleration rate • Referenced “turn off” point • Auto Brake Setting
“Nil”Draft Pilot Reporting Criteria • (Max) Thrust reverser utilized until stop. Directional control dependant on aerodynamic forces only (modulated TR use). Poor directional control even while taxiing. Full brake application with little or no effect. (Full anti-skid cycling throughout rollout.)
