1.2.2.6 Gear panel
The landing gear (LG) and its doors are operated by hydraulic
system B. It has two main gears (MLG) and one nosewheel
(NLG).
The gear handle commands LG retraction or extension. A red
warning light in the top of the handle illuminates when the LG
and doors are in transit or have failed to lock in position. The
light also comes on below 10000 feet when all LG are not down
and locked, airspeed is less than 190 knots and rate of descent
is greater than 250 feet per minute.
In real aircraft the handle is locked in the up position to prevent
inadvertent lowering of the gear. To lower the gear the pilot has to depress the white pushbutton
located on the landing gear handle. This is not implemented in BMS.
The DN LOCK REL button is not implemented either in BMS. In the real jet it allows the pilot to retract
the LG on the ground by depressing this yellow button and moving the LG handle up. Indeed once
WOW is activated, the landing gear cannot be retracted unless this safety button is depressed.
What is implemented though is the WOW switch (Weight On Wheels). Once weight is on the gear
struts the WOW switch is activated allowing or terminating various system functions.
The three green wheels down indicators come on whenever the respective landing gear is down and
locked. A full gear down and locked indication is given when all three lights are green and the red
lollipop handle light is off.
The hook shaped switch above the LG handle is a two-position toggle switch operating the
emergency arrestment system. While it is implemented on the BMS F-16 there is unfortunately no
arrestment gear on any Falcon airbase yet, so it can currently be considered procedural only.
When the hook is down the HOOK caution light located on the caution panel (right aux) is illuminated.
The LIGHTS LANDING/TAXI light also has a specific shaped cap and operates the landing/taxi lights.
The real jet has a three-position switch because of the distinction made between the landing light and
the taxi light. In BMS we have no such distinction and the switch is a two-position toggle: up for light
on and down for off. Please note: the Per-Pixel Lighting option (on by default in
Hardware > Shaders
> Lighting Effects ) must be checked in Falcon BMS.cfg for the lights to be correctly visible.
The HORN SILENCER white pushbutton when depressed silences the VMS low speed/gear horn.
The horn becomes audible when the following conditions are met: below 10000ft, less than 190 knots,
gear not down and locked, sink rate greater than 250 fpm.
The STORES CONFIG CATI/CATIII switch is a two-position toggle switch: CATI and CATIII. CATIII
position should be selected when the aircraft is configured with a category III loading; AOA limiter is
then provided. Please refer to the FLCS chapter for further discussion.
The GND JETT switch is a two-position toggle switch: ENABLE and OFF. In ENABLE it allows the
pilot to jettison his load on the ground. Obviously in OFF this jettison is not possible.
The BRAKES channel switch is not implemented in BMS. We only have one channel brake and
aircraft braking is provided by the toebrakes. For those not having 3-axis rudder pedals the toebrakes
can also be implemented with a keystroke. It is strongly advised to use toebrake pedals in BMS as
differential braking is implemented. Please refer to the brakes chapter for further discussion about the
F-16 braking system.
The PARKING BRAKE switch is a magnetically held switch. In the real jet it has three positions but
the ANTI-SKID functionality is not implemented in BMS and thus it is a two-position switch in the BMS
cockpit.
