Landing gear emergency procedures: landing gear is stuck what should I do?
-
In the real aircraft there is a safety button you have to depress to lower the gear. It’s a small white button on the gear handle.
if you don’t press that one, the landing gear lever will not move down. it’s locked especially to prevent what happened to you.
Unfortunately, that is not implemented in BMS, and when you think about it, it wouldn’t be easy to implement to click two different buttons at the same time with the same mouse.
it could be impelmented with callbacks though, but in the end, it is the same result as putting that callback into a complicated button association. -

Not that that is necessarily the teams goal, and not that it cannot be done with the current BMS version.

Pitbuilders don’t have the issue as the white button doesn’t require a callback but just a 12v locking mechanism that’s bypassed only when the button is pressed
Works great alreadyI have the white button implemented in my pit, thanks to MArtin’s gearbox

Does that mean that my LG is broken?
Any ideas?Yes and yes.
“Lumper” gave you a good answer, … read the Dash-1.

1.2.2.1 ALT GEAR HANDLEThis handle is used to extend the landing gear when normal extension is not possible (in case of
hydraulic failure due to engine flameout for instance). Pulling the handle provides enough pneumatic
pressure to open the gear doors and extend the landing gear. Please note you can lower the gear
with the alternate handle only once as the pneumatic pressure cannot be recharged in flight.
The ALT GEAR RESET button (white button in the centre of the handle) allows retraction of the
landing gear after an alternate extension if hydraulic pressure is available.BMS Key Callbacks for the ALG GEAR handle

1.13 LANDING GEAR & BRAKESThe Landing Gear is operated by hydraulic system B and consists of two main landing gears (MLG)
and a nose wheel (NLG). When hydraulic system B is inoperative the gear can be lowered once
pneumatically with the alternate gear handle located outboard of the left auxiliary console. Once
depleted, pneumatic pressure cannot be restored but the reset button allows retracting the gear after
an alternate extension if system B hydraulic power becomes available again.The main landing gear handle is the primary control to extend and retract the gear. A red warning light
is located in the lollipop and comes on whenever the gear and doors are in transit or when the landing
gear has failed (open or closed). The lollipop warning light also comes on when the TO/LDG CONFIG
warning light (right eyebrow) comes on. The conditions are airspeed less than 190 knots, rate of
descent greater than 250 ft/min, altitude less than 10000 feet and any gear leg is not down and
locked. The gear operating limit speed is 305 knots. All gear legs must be retracted before reaching
that speed to prevent gear damage or failure in flight.On the ground the gear is locked in place mechanically and cannot be retracted (unless using the DN
LOCK REL button prior to raising the handle but that is not implemented in BMS).
A switch is activated when there is weight on wheels (WOW) that activates or deactivates aircraft
systems depending on if the aircraft is on the ground or in flight.**Cheers, :yo:

You guys are awesome! I always get helpful answers every time I post in this forum!
Thank you all again, I will be posting more, I like learning new things about BMS. To this day I don’t believe that there is a combat flight simulator nearly as good as BMS is at the moment, and maybe; DCS A10 comes close… And I can’t say that for the DCS F18 but we will see!Yes I will take the LG from there ASAP! Thereisnotime I’m using the X52 and ok it’s not the best joystick that one can find, but at least for its price it is good so far, especially now that I finally figured out how to make shifted callbacks to work!

AFAlternateGearResetI see. So I guess in the cockpit for the ALT Gear handle, it is right click to extend it and left click to retract it?
cheers

I have mapped the “Gear Up” on CTL + PG UP and “Gear Down” on CTL + PG DOWN … so I have my “lock” button and won’t lower it by accident just by pressing on single key.

Funny you should note that, Sir - I was just about to respond to Red Dog’s comment about the difficulty in mapping a “compound control” in a mouse-clickable cockpit… Old sims where only the keyboard was usable never had that sort of problem if you could re-map the keystrokes to your liking. Most sims always had at least sensitive controls like the ejection handle mapped to a shift-, command-, or control- binding so you could not simply perform a serious or dangerous operation without intent.
However, if coders care to do something about accidentally pulling the gear lever in the 3D cockpit, it might be time to implement a click-and-drag interface if feasible. Obviously that is far easier said than done…

i just use the logitech software so that two buttons on a certain mode equals a =G input on the keyboard.

Maybe it could work like ejection where you need to hold down the key for a few milliseconds

No, it is a one shot use only to lower the gear. It cannot retrack the landing gear.
