Flight Crew Rejected Takeoff
Human Factors
We had a rejected takeoff for improper flaps setting. It was only my second trip of the month; and I have not had a flight with flaps 8 in over a month. In my opinion this was just human error.
The First Officer who was also the pilot flying stated that the flaps were in the wrong position while on the takeoff roll at about 110 KTS. I called for the abort; took control of the aircraft and carried out the rejected takeoff procedures. We advised the Tower; exited the runway; ran the QRH for aborted takeoff; notified the Flight Attendant and made a PA to the passengers. We discovered that the flaps were set at 20 and they should have been set at 8. While taxiing back we notified Dispatch and Maintenance. Maintenance informed us that a brake/wheel inspection was not required in accordance to the AMM [Aircraft Maintenance Manual] because the BTMS [Brake Temperature Monitoring System] was operative. We waited the required 15 minutes and had to compute a new V1/V1MBE [Maximum Brake Energy] because the right outboard BTMS was reading 06. The computation was within limits and the flight was continued.The flaps should have been set to 8 during the Taxi Checklist. It was on the Takeoff Card but the First Officer could not remember if he briefed a flaps 8 or 20 takeoff. It was day three and we were accustomed to making all flaps 20 takeoffs. My recommendation is to change one word on the Taxi Checklist just to remind the Captain to confirm the planned setting. By changing the word 'SET' to 'VERIFY' when the First Officer challenges 'FLAPS'; it will remind the Captain to once again verify that the flap setting is as planned. Thus: 'FLAPS.......VERIFY______INDICATING_______for RWY_______.'
A CL65 flight crew rejected their takeoff at high speed when the First Officer noted the flap setting was not as briefed.
