When waay back in history I was preparing for a multi-engine rating my instructor Steve Barlow stressed to me the importance of constantly evaluating during every takeoff at every moment-during-that-event to ask myself “What do I do if an engine quits NOW?….what about NOW?….. and NOW?….”
When I advanced in my career to a small airline job it was such a lackadaisical operation (Rio Airways, Killeen, TX Be-99s) where FOs were relegated to counting/collecting boarding-passes and making a cabin-announcement during taxi-out and “get it done before I get into the takeoff roll!” ….
Take-Off briefings between “crewmembers” in that operation was virtually unheard of.
It was when I began training as a corporate pilot at Flight Safety, Inc in turbine equipment that the Take-Off Briefing was introduced to me. Standard Operating Procedures (SOPs) began to infiltrate General Aviation when the “real regulators”….(IE, Insurance Underwriters)… began to take interest in corporate and GA ops.
When I became responsible as a chief pilot at corporate operations is when my attention to such details as SOPs became important to me because I was responsible for a dozen pilots who might fly with anyone else in the flt-dept…OR…may even find themselves operating with a “contract” pilot hired to cover a short-term insufficiency. It became mandatory for each crewmember to know what to expect from his/her partner up in the pointy-end where they could be first-to-arrive-at-the-scene-of-the-accident.
It became “habit”. In fact, I didn’t realize how habitual my typical takeoff brief had become until one day a passenger expressed shock and dismay that I had briefed them what I planned to do …in what sounded to them like the absolute certainty we were about to have an emergency!

It was in my personal Baron that I typically briefed to whomever was sitting next to me:
“We will apply maximum power and Confirm it before beginning the takeoff.
“In the event of engine malfunction Prior to rotation we will STOP straight-ahead…
…otherwise we will climb at Vy (or Vx) until the departure end of the runway….
…leaving the gear DOWN until we are no longer able to land on the remaining runway.
After that, we will retract the gear, clear obstacles, then accelerate to Flap-retraction…
…and then go to cruise-climb….
Any malfunction after rotation we will address by the checklist and decide to return or proceed.
Any Questions…??
It became so ordinary that when I sold the Baron I continued my TO Brief even in Single-engined airplanes…
… except that in the event of engine failure I plan to land straight ahead until sufficient altitude to do otherwise…. which I’ve always felt was about 1K AGL. I still tell my “new” pax this briefing. I still think it to myself even when alone. (I quit briefing Jamie because she quit listening to me years-ago.)
When I administer a Flight Review one of my regular and Favorite things to do …JUST before the client pulls into position…is to Ask: At what point do you intend to abort this take-off?
It almost Always brings a shocked/confused response….sometimes with their question. “Whaddya MEAN?”
Me: “I mean, will you abort when half the runway is behind you and you’ve not attained flying speed…??? Or will you abort at BRAKE RELEASE when the Tach shows LESS than 2300 RPM..?? (or whatever T.O. power should indicate in whatever airplane we are in. for a standard 170…it should be approx 2300 at S.L.)
It’s surprising how many private/pleasure pilots … (and even some guys who fly professionally… but then fail to brief in a personal airplane)… simply do not think about the fact that trouble can actually occur during a takeoff/departure!

By asking the client this question, I hope to provoke them into making this a habit Before EVERY TAKE-OFF for the rest of their flying career.
I encourage all pilots to begin critical-thinking long before the actual departure.
Example: When you first “crank” your engine… Do you look to see if the Ammeter shows a DIS-charge?
Immediately AFTER start… as soon as you confirm Oil Pressure…Do you look at the Ammeter to confirm it shows a CHARGE?
In your “RunUp” checklist….Do you confirm your Ammeter has reduced to near-ZERO charge indicating that your battery has RE-charged before TakeOff?
(If not, then something in your charging system is not working properly and you might wish to reconsider departing, especially at dusk/after-dark…. remembering that the purpose of your battery is NOT to START the engine ….although that is a good test of battery capacity…. The PURPOSE of the battery is to provide an Emergency Source of electricity in the event of charging system failure in-flight. This is especially critical at night and in IMC.)
This is an important part of every “Before Take Off” checklist…. Your battery should be at/near Full-Capacity before Take-Off.
(Below 10-Amp recharge-rate is my personal requirement.)
Anyway,… Think About Take-OFF briefings….and while doing that…. Think about including your passengers in the briefing. (What about abandoning the airplane in a take-off incident and how they’re going to get that door open…. and WHICH door if that side is on fire. How do they unlatch seat/shoulder harnesses? (That item may have contributed to the deaths of pax in the NYC helicopter ditching.)
Hope this helps.
