I have flown with one CFI who requires those items for takeoff "outs" be stated out loud prior to taking the runway.
In fact, for students to get into the habit, he requires a full takeoff and landing data sheet filled out for every flight (later he backs that off to keeping copies for various weights or utilizing electronic tools if you normally fly that way) that includes a takeoff abort section with blanks for altitudes and amount of turn, etc.
He makes it clear that there's at least three distinct altitudes...
- No turns or only mild ones to avoid the largest/hardwest obstacles. Straight ahead. Stop on runway, re-land on runway remaining or pick the softest most inviting looking stuff ahead there.
- Turns okay but we're not high enough to return to the runway. Go into known fields/open areas at airports you're familiar with, or pick the best looking option if not, and commit to it.
- Runway return altitude. Nose aggressively down, high bank angle. Pull and nail target airspeed. Don't attempt if you're not in practice. Go back to level 2 and survive.
I go in and out of the habit of saying it all out loud, but his point stuck. I always think actively about it before pushing the throttle forward.
Sometimes saying it out loud concerns passengers. "Below 400 feet, no turns more than twenty degrees left or right of centerline, we will be landing straight ahead." etc... Kinda has the effect of freaking out new pax. Sometimes it's wiser to just say it to myself. But it's always there. He pounded it into my thick skull.
And it may just save my life someday.
Thus, they cannot know what percentage result in fatalities, because they don't know the denominator - The number of attempts.
