FLAP CONTROL LEVER
The FLAP control lever operates in one of four positions, (0, 10, 20, and 30) with detents at the 10 and 20 positions.To
prevent inadvertent retraction of flaps from 30 to 0 in one motion during a go-around maneuver, a gate is located at the 10
position and must be pulled up slightly when retracting the flaps to 0. The lever is attached to dual RVDTs co-located with
a flap lever detent switch below the flap handle. These dual RVDTs transmit the selected position to a flap control unit.
Moving the lever between positions actuates the flap lever detent switch and energizes a 75-second timing circuit within
the flap control unit. This circuit allows the arming solenoid valve within the flap power unit to energize open for 75 sec-
onds and then de-energize.
FLAP POSITION INDICATION
Flap position is shown in a digital display on the (EICAS) and flight control synoptic page.
