DESCRIPTION
ILCA DRIVE Group
Six switches used in conjunction with the ILCA DRIVE position of the
METER SOURCE switch.
PITCH command switch S 19
Switch, rotary, 5-position.
Selects one of five discrete command signals. Command signals are used
to drive the pitch extensible link. Feedback voltage, proportionate to link
position, cancels input signal and stops link.
MAX RETR. Retract signal (+3.91 vdc) drives the link to the har-
dover position.
85%. Retract signal (+2.89 Vdc) drives link to standard retract input -
position (85%).
0. Drive voltage is balanced (0.0 vdc) and the extensible link is at neu-
tral.
85%. Extend signal (-2.89 vdc) drives link to the standard extend
input position (85 %).
MAX EXT. Extend signal (-3.91 vdc) drives the link to the hardover
position.
ROLL command switch S20
YAW command switch S21
Switch, rotary, 5-position.
Selects one of five discrete command signals. Command signals are used
to drive the roll extensible link. Feedback voltage, proportionate to link
position, cancels input signal and stops link.
MAX RETR. Retract signal (+3.91 vdc) drives the link to the har-
clover position.
85%. Retract signal (+2.89 vdc) drives link to standard retract input
position (85%).
O. Drive voltage is balanced (0.0 vdc) and the extensible link is at neu-
tral.
85%. Extend signal (-2.89 vdc) drives link to the standard extend
input position (85 %).
MAX EXT. Extend signal (–3.91 vdc) drives the link to the hardover
position.
Switch, rotary, 5-position.
Selects one of five discrete command signals. Command signals are used
to drive the yaw extensible link. Feedback voltage, proportionate to link
position, cancels input signal and stops link.
MAX RETR. Retract signal (+3.91 vdc) drives the link to the har-
dover position.
85%. Retract signal (+2.89 vdc) drives link to the standard retract
input position (85%).
O. Drive voltage is balanced (0.0 vdc) and the extensible link is at neu-
tral.
85%. Extend signal (–2.89 vdc) drives link to the standard extend
input position (85%).
MAX EXT. Extend signal (-3.91 vdc) drives the link to the hardover
position.
