[Two common methods of designing checks for completing the before take-off requirements are:
- a single check that is divided into two sections, one for items completed before taxiing into the take-off position, and the second for after taxiing into position;
- two separate checks a "Before Take-off Check" that is completed before taxiing into the take-off position, and a "Runway Check" that is completed after taxiing into position.
In this section, specify the checks and crew coordination applicable to your operation. The example in this section is of single check with two sections.]
The Before Take-off Check should be requested by the PF approaching the take-off point. The PNF shall then complete the Before Take-off Check items above the separator line on the checklist. The PNF will then say "Complete down to the line" and hold the checklist with no further comment until requested by the PF to continue or until cleared by the ATC Tower for take-off. The PNF will then complete the check. The initial part of the Before Take-off Check is normally carried out prior to requesting take-off clearance. The expanded Before Take-off Check follows.
BEFORE TAKE-OFF CHECK (Challenge and Response)
Standby for Take-off (PNF/FA) - Cabin Secure
- It is necessary to establish contact with the Flight Attendant (FA) to ensure that the cabin is secure prior to take-off. Normally the public address system is chimed three times to about one minute before take-off to allow the FA to occupy their assigned station.
Flight Controls (PNF) - Checked
- The Flight Controls are unlocked at this point. Care should be taken in strong winds.
Bleeds (PNF) - OFF
(PNF) - Complete down to the line
The check should be held at this point until Take-off clearance is issued by Tower ATC or until requested by the PF
Transponder (PNF) - ON/ALT
- The transponder should be left at standby until as late as practical before take-off. Then, it should be set to ON and the Altitude Encoding turned on.
LANDING & A/COL Lights (PNF) - ON/WHITE
- Turning the Landing Lights on and the Anti-collision Lights to white should be delayed until clearance for take-off has been received from the ATC Tower. If the aerodrome is not controlled by a Tower then the lights should be selected as soon as the aircraft taxies onto the runway.
Altimeters (PF/PNF) - Checked
- The pilot and co-pilot altimeters should be checked against the runway elevation (if available) and against each other.
Compasses (PF/PNF) - Set/Checked
- The compasses should be set if required and compared to the runway bearing.
- Before Take-off Check (PNF) - Complete
