25.1.11 Pitch Trim Inputs
The GAD 27 has 4 active low Pitch discrete inputs that allow for manual control of pitch trim motors.
Pilot switches take priority over copilot switches when they disagree unless pilot switches are both
inactive. Copilot trim switches are optional.
These active-low discrete inputs conform to the following specification:
Low: Vin < 3.5 VDC, or Rin < 375 (input active)
High: Vin > 8 VDC, or Rin > 100k (input inactive)
25.1.12 Roll Trim Inputs
The GAD 27 has 4 active low Roll discrete inputs. Pilot switches take priority over copilot switches when
they disagree unless pilot switches are both inactive. Copilot trim switches are optional.
These active-low discrete inputs conform to the following specification:
Low: Vin < 3.5 VDC, or Rin < 375 (input active)
High: Vin > 8 VDC, or Rin > 100k (input inactive)
25.1.13 Yaw Trim Inputs
The GAD 27 has 2 active low Yaw discrete inputs.
These active-low discrete inputs conform to the following specification:
Low: Vin < 3.5 VDC, or Rin < 375 (input active)
High: Vin > 8 VDC, or Rin > 100k (input inactive
