A common misconception but, although most conventional aircraft have negative lift, ie downforce, at the tail, this is not a requirement.
The canard configuration is a lifting tail taken to it's logical extreme .

Our briefing goes something like this:-

"This will be a left/right seat take-off with weight at xxxkgs, speeds set V1-x, Vr-y, V2-z.

Any failures before V1, either crew member state the failure and (Captain) will decide to stop or continue.

Departure is Bla bla 2c that way, this way (waypoints or radials) climbing (cleared level) with minimum rate (if specified (noise abatement procedure)).

Failure after V1 check max power (perhaps uptrim + autofeather on a turboprop) and in case of fire silence the Master Warning.

Otherwise, no action below acceleration at (4-500'agl) except on (Your or my) command. (Captain has the last say).

Contingency procedure, perhaps and/or obstacles in departure area.

Any questions?"

There's a start for you.
