These are the Aztec procedures, cut & pasted from the routine checklist. SOP requires that ACC-Stop distance is already calculated prior to this and its outcome factors into the decision making process.

DEPARTURE & CAPTAINS BRIEF
Departure is via RWY ____, climbing to ________ and tracking via NDB/VOR/GPS/RADAR to course ______

Take-Off Safety Speed is ____; Blue-Line Speed is 89kt; Best SE ROC is 102kt.

In the event of an engine fire or failure BELOW 89kt, I will abandon the takeoff, shut both throttles, apply maximum braking and pull up straight ahead.

In the event of an engine failure ABOVE 89kt, I will continue the take-off. I will MAINTAIN DIRECTIONAL CONTROL, NOT BELOW 89kts.
MAXIMUM RICH MIXTURE, MAXIMUM PROP PITCH, MAXIMUM THROTTLE.
FLAPS UP and GEAR UP, using hand pump if LEFT ENGINE.
IDENTIFY failed engine – DEAD ENGINE, DEAD LEG
VERIFY with throttle and EGT
FEATHER & SECURE; RUDDER TRIM; 3 BANK INTO LIVE ENGINE
ACCELERATE TO 102kt if able
CIRCUIT & LAND

I read it aloud and go through the motions during backtracking and line-up on every takeoff, and add in where necessary for particular local situations, for instance if circuit & land is not the best option in a particular location. (I switch the audio to 'Pilot' or 'Crew' so the pax don't get all hot and bothered.)

*****

And these are from the POH Emergency Procedures

ENGINE FAILURE DURING TAKE-OFF

Blue-Line Speed is 89kt; Best SE ROC is 102kt.

In the event of an engine fire or failure BELOW 89kt:

· IF STILL ON THE GROUND APPLY MAXIMUM BRAKING AND PULL UP STRAIGHT AHEAD.
· IF AIRBORNE ABANDON THE TAKEOFF, SHUT BOTH THROTTLES, LOCATE A SUITABLE SITE WITHIN 30 OF THE FLIGHTPATH AND LAND AT MINIMUM CONTROL SPEED – SHUT OFF FUEL & SWITCHES PRIOR TO IMPACT.

In the event of an engine failure ABOVE 89kt:

· CONTINUE THE TAKE-OFF.
· MAINTAIN DIRECTIONAL CONTROL, NOT BELOW 89kts.
· MAXIMUM RICH MIXTURE, MAXIMUM PROP PITCH, MAXIMUM THROTTLE.
· FLAPS UP and GEAR UP, using hand pump if LEFT ENGINE.
· IDENTIFY failed engine
· VERIFY with throttle and EGT
· FEATHER & SECURE; RUDDER TRIM; 3 BANK INTO LIVE ENGINE
· ACCELERATE TO 102kt if able
· IF UNABLE TO MAINTAIN ABOVE 89kt LOCATE A SUITABLE SITE WITHIN 30 OF THE FLIGHTPATH AND LAND AT MINIMUM CONTROL SPEED – SHUT OFF FUEL & SWITCHES PRIOR TO IMPACT
· CIRCUIT & LAND or other manoeuvre as deemed appropriate by PIC for circumstances



And here is the pax brief as well.......

FLIGHT BRIEF -
Flight Details Emergency Exits Smoking
Luggage Emesis Bags Electronic Equipment
Seating Intercom Flotation Devices
Seatbelts Look-Out Fire Extinguisher Survival Equipment Movement Oxygen

I would suggest you do as SG advised, but make your FLIGHT BRIEF and DEPARTURE & CAPTAINS BRIEF part of your routine pre-takeoff system in every aircraft you fly, not something you only dredge out for the annual renewal.

Please remember that light twins (even Aztecs too
) are not renowned for being able to climb on one fan. Make it part of your psychological mindset that an EFATO may very well mean a controlled crash on one engine.
