Characteristics in pitch
- When acting on the stick the pilot commands a constant G load maneuver and the aircraft response is G Load / Pitch rate. The pilot order is therefore consistent with the aircraft response “naturally” expected by the pilot, Pitch rate at low speed / Flight Path rate or G at high speed.
- Hence STICK FREE, the A/C maintains the flight path even in case of speed changes. Furthermore, STICK FREE in case of Configuration changes, or thrust variations, etc… the pitching moment effects are reduced by the feedbacks in the control law itself and compensated for by precommands. With STICK FREE in turbulence, small deviations do occur on the flight path but with a tendency of the A/C to regain a steady condition.
As a consequence the A/C is a STABLE PLATFORM and AUTOTRIMMED; it needs to be flown with minor corrections from the pilot on the stick, when the A/C deviates from its intended flight path.
