Downlock Solenoid Override Button

[REL]

Hey Guys

 

Just curious is there a reason why the Downlock Solenoid Override Button is not functional.

 

IMHO seems like this one is relatively easy to model (of course I could be totally wrong here).

 

I did wonder if the reason is that this is another canceled legacy button from the A-10A but ... I couldn't fined the info to back it up.

I am sorry any information on the downlock solenoid override button is classified.

:D

I don't have DCS:WH yet, but I believe that it is functional.

This came up in another thread and I cited the same image, but pitbldr had this to say:

Regardless of what the BETA manual states, I just loaded up the sim and was able to raise the landing gear lever while holding in the downlock override. I could not raise the lever without holding that switch in.

+1 what pitbldr said, same here

I'm confused by this, I can raise and lower the gear without holding anything in. When would you use this thing?

[recoil17]

The downlock solenoid button is used to release the lock that holds the gear up. This way if there is hydraulic failure you can press this button and aerodynamic forces will force the gear down. That's why they are pointing forward.

 

I read this somewhere in the manual but can't seem to find it right now.

 

EDIT: Page 101

 

If however both hydraulic systems are inoperative, the landing gear locks can be released and gravity and aerodynamic forces will likely extend the landing gear.

 

ALSO FOUND THIS. This proves my theory wrong. It's a DOWN lock and not an UP LOCK, I guess.

 

Before the handle can be moved to the up position (raise landing gear), when DC power is available, there must be no weight-on-wheels, or the Downlock Override button is also depressed.

Actually it is the History Eraser Button

I would be interested in seeing the NWS Safety Switch Breaker added to the breaker panel as well. This is a safety switch that prevents you from doing certain things on the ground, like firing weapons. If the switch were on the bus panel you could fire the guns on the ground, which I find to be extremely important! :)

In RL, During maintenance or if one of your W.O.W. switches malfunctions/fails and the aircraft thinks it's on the ground, this would allow you to raise the landing gear.

 

Also, in RL, before lowering the gear, you would have to press the down permission switch. This is to help avoid unintentional gear extension.

 

I guess anyway.

IIRC this can only be accessed through a maintenance panel, as it was deemed too dangerous to be put in the hands of a pilot :D

Yesterday I smacked my plane against the runway trying to land for the second time.

when I realized I landed not too far from the end of it I Maxed the throttles, retracted the flaps and took-off.

after some time I tried to retract the landing gear but the red lamp stayed on.

 

handle down ... handle up ... still red and beeping!

 

handle down ... Only One green!

 

hmmm ... something definitely stuck!

 

the hydraulic systems looks good!

 

bad landing? ... over speed landing gear operation?... maybe both !

 

Anyway I didn't know how to use the "LDG GEAR DOWN" or the " Downlock Solenoid Override Button"

So ... What Should I do next time ???

 

This one make me think I need to press the Downlock Solenoid Override Button until the gear extended with the assistance of gravity and aerodynamic forces.

The downlock override is when the gear is stuck down and you need to get it up. The "downlock" are the locks that hold your gear in the down position. If you were on the downlocks to begin with you wouldn't have a problem.

 

After a hard smack with the gear down green... don't try to operate the gear! If you have gear stuck up, try to shake the gear down with turns, airspeed, and G's while having the main extension hydraulics helping. If that doesn't work try the AUX LG EXT pull (which uses right hyd as opposed to left) and then the same shake, speed, G dance.

 

With all attempts to extend the gear unsuccessful, it's time to land in the best configuration possible.

This.

Thanks for clearing that out for me ... I will try it next time!

According the the A-10A manual, the landing gear handle is locked into the down position until weight is removed from the wheels or the DOWNLOCK overide button is depressed. Once the button is depressed, the handle can move to the up position. It also states that even after pressing the downlock overide button and moving the handle to the up position, the gear will not retract until weight is removed from the gear and the struts are extended.

 

 

DOWN LOCK

SOLENOID OVERRIDE BUTTON

The down lock

solenoid override button (33, figure

FO-l), is located on the landing gear control panel

and placarded DOWN LOCK OVERRIDE. Depressing

the button allows the landing

gear handle to be

moved to UP even if aircraft weight is on the main

gear. However, the nose and main gear will not

retract until weight has been removed from the

main gear and both

struts have extended. The

button is powered by the DC essential bus.

Jolly good infos, +1.

Yep- although I have not seen it in an A-10, from other a/c there is a "J hook" that extends over the landing gear handle itself physically stopping the movement of the gear handle when you have weight on wheels. Pressing the downlock overide will release that J hook. Sometimes if your weight on wheels switch is dicky on touch and goes you will see the J hook hammering away on the gear handle as you bounce up and down.

Hi,

I have seen hotrod pilots:smartass: flip the gear up when they are beginning their takeoff run and as soon as the weight is taken off the wheels the gear immediately retracts.:thumbup: But if their is a problem with the weight on wheels switch it could be the end of a pilots career:cry:

Where I work, the only use of a downlock release switch is when you need the gear up to clear an obstacle. That's it. Of course you won't be fired for playing with yours in the game, so have fun with it!

May I ask what aircraft you are referring to? In all of the aircraft I've read about, the gear is left down until clearing an obstacle, because the act of retracting the gear could cause more drag than the gear being down.
