a) To check the other guy is still alive
b) Airspeed indicator check
c) In our company, below 80 kts stop for significant malfunction, above 80kts, stop only for engine failure / fire etc.

Dylsexlic says
it's just routine "role" play
Dylsexlic yes.............but at least I can spell "cocktip"

Expedite climbe is right:
a) To check the other guy is still alive
b) Airspeed indicator check
c) In our company, below 80 kts stop for significant malfunction, above 80kts, stop only for engine failure / fire etc.

Agreed Capt. Inop, expedite_climb got it right, to add 2 more to the list which may not be typical of all aircraft -
(1) For EPR gauged aircraft there is a defined speed by which the Takeoff EPR must be set, and then left unadjusted for the remainder of the Takeoff due to changeing EPR indications due to forward speed. A typical speed is 80 knots, for the RR Trent B777 the Auto-Thrust is in "Thrust Ref" mode up to 80 knots, and "HOLD" beyond that. Speeds may vary for other types.
(2) Some aircraft have quite limited Nose Wheel Steering authority through the rudder pedals, and it is procedure with some operators that, at low speeds, the PF holds the Steering tiller with one hand and the thrust levers with the other, whilst the PNF holds the control column. Changeover takes place when rudder effectiveness suffices for directional control, and again, 80 knots is a fairly typical speed. Speeds may vary for other types and operators. (I'm glad to be rid of that one).
