7.3.1.1. PITCH MODE
Pitch attitude boundaries set are based on P-Mentor aircraft performances.
When pitch attitude exceeds the pitch limits, the ESP engages the pitch servo applying
an opposing force to encourage control movement in the direction of normal pitch
attitude range for the aircraft.
The ESP pitch engagement values are the following:
Nose above the horizon:
Engagement threshold: + 24°
Disengagement low threshold: + 19°
Maximum ESP Torque: + 29°
Nose below the horizon:
Engagement threshold: - 15°
Disengagement low threshold: - 10°
Maximum ESP Torque: - 20°
Once ESP pitch mode is engaged, the torque applied by ESP increase linearly up to its
maximum value when pitch is 5º more than the configured nose-up and nose-down
pitch limits, and tapers to the minimum applied torque when pitch is 5º less than the
configured nose-up and nose-down pitch limits. When beyond 5º of the configured pitch
limit, the maximum torque is held until the aircraft returns inside the protected envelope.
When pitch attitude decreases below 5° lower than the pitch limit, the ESP disengage.
