Emergency Gear deployment

[The_Tau]

Hello,

Is there any emergency gear deployment procedure in case of lack of hydro pressure? 

I thought that in this situation gear should deploy under its own weight and if its stubborn then rocking wings should help gear get lowered in lock position.

But in DCS it doesnt seem to happen, gear gets stuck halfway and no rocking or hand pumping would do anything to help gear get lowered

Am I missing something?

On the left side of the cockpit there is a manual lever that you can use to pump hydraulic pressure until the gear goes down completely.

yeah i tried that, and it doesnt work. I tried flaps to neutral too.

Yes, but the OP said that operating the pump does not solve the issue of the landing gear not deploying fully.

yup, I realize that, will test it tonight. This emergency procedure helps when the hydraulic pump goes out. However, if the hydraulic lines are severed it won't help much, at least that's how I understand it.

edit: re-read his post, yup, no hydraulic pressure, so this pump thingie won't work. Why it doesn't extend under its own weight I have no idea..

Considering this 

18:15

 

Maybe this topic should be moved to Bug section. rocking, yawing wings do nothing

will need to simulate a hydraulic failure (in ME), and try to lower the gear, then attach a track and summon @NineLine

I did just that.

@NineLine your input?

Marianas mission, after 1 min hyd failure is enabled and you can see hyd pressure going to 0 in cockpit. 

Gear doesnt deploy fully in emergency, even with hand pump and flaps neutral.

Interesting that flying upside down, allows you to retract gear and even lock it in place. I guess good to know

P47 gear no hyd.trk

Also I would add that ground crew repair for gear doesnt work properly in P47. The "floating" part of repair (when damaged plane is lifted in air) is too short for repaired gear to fully deploy, damaging it again after repair is completed and plane placed on ground again.

Did they ever add a neutral position for the landing gear?

We need that position so we can operate the flaps with the hand pump.
