There is a maximum speed that the system can handle:

> Four CAPS deployments occurred successfully at higher speeds, 168, 171, 187 and 190 knots indicated airspeed, and one deployment failed at an airspeed estimated at over 300 knots airspeed.

Anything lower than that will forward-motion stop the aircraft. AFAICT, there is a need for 2000' (650m) of altitude above the ground for the system to deploy in time to be useful (slow descent).

Official Cirrus guidelines include verbalizing "CAPS is available" when crossing 600ft AGL during climb-out.

Even then, they recommend pulling the chute anyway because it can reduce velocity if it’s still above nominal “touchdown” speed
