** NOTE: ALT OUT light on if voltage drops 1.5-2.0V below bus voltage or if over-voltage relay actuated

FUEL SYSTEM
-----------
** NOTE: Wet wing tip with 200 gal total, 194 usable (drained at 8 locations)
** NOTE: Aux Pumps between fuel selector & eng-driven pump, fed from inboard leading-edge tanks
** NOTE: Three bladder-type fuel cells in each wing
** NOTE: Fuel pump driven off accessory drive of engine, fuel enters pump at 28-31 PSI

LANDING GEAR/BRAKES
-------------------
** NOTE: 28V DC split-field, series wound motor; Drives worm gear
** NOTE: Left Gear strut houses auto safety switch and gear warning horn switch (squat switch?)

  ** NOTE: Gear up with more than 15° Flaps used
** NOTE: Air-oil struts on landing gear
** NOTE: Main tires: 70 PSI; Nosewheel tire: 50 PSI

FLIGHT CONTROLS
---------------
** NOTE: Flaps: electrically driven by motor under cabin floor; trailing edge fowler flaps (single-slotted)
  ** NOTE: Flap position transmitter on flap actuator in left wing, forward of rear spar.
** NOTE: Ailerons: cables routed through bellcranks and pulleys
** NOTE: Aileron Trim: on left aileron; push-pull rod attached to jackscrew-type actuator
** NOTE: Elevator: connected to cables to a torque tube which is connected to a bellcrank in tail
** NOTE: Elevator Trim: located on left and right elevators; push-pull rods attached to jackscrew actuators
** NOTE: Rudder: bellcrank attached to bottom of rudder and cables
