Encore takeoff emergency briefing
CA: In the event of a rejected takeoff before V1, I will call reject and: Select Disc and apply max braking Stop the aircraft Once stopped I will: Set the emerg brake Command the checklist Advise the flight attendants and passengers. FO: I will advise ATC, call 60 knots, standby to initiate the checklist as commanded PF: In the event of an engine failure or fire after V1, I will continue the takeoff, rotate normally at Vr. PNF: I will call positive rate PF: I will call gear up Climb at V2 to flap retraction altitude Call for the QRC at a safe altitude Retract the flaps on schedule Climb at Vclimb to 1500 feet Call for the QRH reference items

Ice accretion on aerodynamic surfaces is not considered to exist at temperatures of -40°C or below
Icing conditions also exist when the SAT on the ground and for takeoff is 10°C or below when operating on ramps, taxiways or runways where surface snow, ice, standing water or slush may be ingested by the engines or freeze on the engines, nacelles, or engine sensor probes
Note: Icing conditions are considered to exist at takeoff where visible moisture (cloud ceiling) is present at 1,000’ AGL or below at a SAT of 5°C or less
