Air System And Electronics (For Models Shipped Prior To September 2015); Psi To Bar Conversion Table - BVM Grumman F-9F Cougar Construction And Operating Manual

Air System and Electronics (For Models shipped prior to September 2015)

The aircraft is fitted with high quality electronic air
actuation valves. These valves are controlled by
the sequencer board shown. The sequencer
features a digital display that displays the air
pressure (bar) in the system. A low pressure
failsafe is set to extend the gear if the pressure
falls below 3 bar in flight. The sequencer comes
pre-programmed with sequencing delay. See the
section titled "Landing Gear/Door /Brake
Sequencer Instructions" if adjustments are
required. The set of two valves are connected to
the gear doors, open and closed. The set of three
are connected to the landing gear; Brakes, gear
Up, and gear Down. The brake valve is non-
proportional, either on or off. Use BVM Super O-
Lube on the main wheel brake drums to prevent
skidding. See the section titled "Lubing the
Brakes" for instructions.
Fill the Air system to 70 psi, or 4.8 bar before each
flight.
Helpful Tip: Use a scrap piece of BVM Air Line
inserted into the fill valve; chamfer the end for easy insertion.
