Translations:Manuals:MB Plus:AttitudeControl usage/5/en

When AttitudeControl is deactivated on the other hand, the swashplate will always be moved back to neutral position (perpendicular to main rotor shaft) as soon as the helicopter is standing still for a few seconds, independant of the current leveling. Here the system only corrects currently occurring rotational movements, but does not regulate the absolute deviation from horizontal position.

When using an AttitudeControl mode with collective pitch control (see chapter 8) additonal to the cyclic movement also the collective pitch is moved in positive or negative direction when AttitudeControl is activated and the helicopter approaches the horizontal position. The pilot can add collective pitch in the same direction by using the thrust stick, but not in the opposite direction. Check to see if this works correctly and whether the control directions are correct. If the helicopter is kept in hovering position, some positive collective pitch must be applied by AttitudeControl and you can use the thrust stick to add more positive pitch, but not less. Analogous this must work when the heli is in inverted hovering position if using the „3D - Mode with collective pitch control“. Here AttitudeControl will apply some negative collective pitch and you can only add more negative pitch, but not positive.
