A quote from the section "SUPPLEMENTAL PROCEDURES Cold Weather Operations" of the official Bombardier CL-604 Operating Manual:
8. PHASE OF FLIGHT PROCEDURES
...
E. Take-Off
...
Considerations:
...
- Do not exceed 3 degrees/second rate of rotation. Anticipate and be prepared to accept a higher than normal initial climb speed. This increased initial climb speed will not adversely affect the climb profile.
...
- If the airplane tends to pitch-up or roll-off once airborne, immediately reduce the pitch to reduce the angle of attack and simultaneously apply maximum thrust. Be prepared to accept altitude loss to recover aircraft. Use ailerons as required to level wings.
