Hydraulic System

[Joni]

I see there is a dual needle pressure indicator for both systems, but there's also a system switch "for gauge display" according to the manual.

 

What does that do exactly since there is already a dual indication?

[jaguara5]

It should show the pressure in the ancillary and emerg brake subsystem in the 2 position

[Joni]

Is it just a guess or based on documents?

 

There is no such thing as ancillary (auxiliary?) and emerg brake subsystem, but there is an Emergency Pump which pumps fluid to the System 2 where the breaks and stuff are.

 

So back to the original question, is that switch actually change the pumps measure?

[jaguara5]

I have the manual from the mirage f1 which has the same indicator / hydraulic system shematic. Have asked the same question a while ago and a member in knowledge confirmed the they same functionality. He provided also a photo from the real indicator where you can see the indications Anc and Emer Brk.

The logic is that in case of a leak two valves isolate the flight controls and emerg brakes from the whole system so there is some pressure preserved for this essential subsystems.

Well, the switch is not working or its a bug

[Joni]

I still dont get your explanation though, sorry about that.

Tbh i do not think the hydraulic system is implemented at all. There have been a few threads about this and the conclusion came from razbam that the m2k has invulnerable hydraulics and it is impossible to get hydraulic failures.... I have not been able to ever have the hydraulic pressure needle move in flight even when i`m heading towards the grounds without wings and on fire. Maybe something has changed lately, because i have given up on m2k few months back...

[Joni]

The needles do move, for instance if you put parking brake

 

I love the Mirage, but it has the world record in bugs and things not working.

[Slims]

The damage stuff/failures are not implemented atm, and as they never got acknowledged i`m not sure they ever will.

What? Are you saying that I've been flying nothing more than a game level module where no system can fail?

 

Nice!!! :mad:

Yeah, welcome to the I-Wish-Someday-RAZBAM-Pay-Some-Attention-To-The-Mirage club!

Not exactly fair, but you go with it!

 

Frankly if you have time to sit and look at the function of a gauge when you're plummeting towards the ground in flames, then perhaps you have your priorities wrong?

 

Sure, it needs addressing, but perhaps the updated flight model and fly by wire systems might take priority? That's what is being worked on right now, so I-Wish-Someday-RAZBAM-Pay-Some-Attention-To-The Mirage club may have something to celebrate after all!

 

Perhaps a quick reading of the current posts might have enlightened you to that, and saved face for you?

[Slims]

Well someone has to check if this stuff is implemented as stated by the developer. I didn`t say the hydraulic system is well implemented, Razbam did. So someone has to fact check. With so many things missing it`s hard to set priorities, and atm nothing has changed, despite the many enlightening posts....

In case of a hydraulic failure, by switching the switch to the 2 position the pilot can see how much pressure is left in the Anc and EmB systems.

See the hydraulic diagrams in the real 2000rdm or the f1 manual (you can google it), it's very helpful to understand the system.

Razbam manual doesn't mention it because it's obvious that these systems are not implemented (yet? - see here https://forums.eagle.ru/showthread.php?p=2727855&highlight=ancillary#post2727855 )

Yes, in this picture you can the switch and the indicator.

Perhaps reading the thread next time is a good idea :)

 

So now I can be flying with a lot of damage to the plane but all systems are perfectly good. Its so unrealistic. If thats not important for you in a simulation you are free to leave the thread. But for us real life pilots its a deal breaker.

[Joni]

Wow, nice pic! Why is our bird in dcs so different than that photo?

 

And why do you have a switch with the same labels as the dual needles?

 

 

Thanks

My picture and this one:

are taken on a training airframe with transparent fuselage.

The cockpit is set up to export Mirage 2000E standard with English cockpit.

 

In French:

- Ancillary = Servitudes = Sdes

- Emergency Brake = Freins Secours = F.S.

 

And why do you have a switch with the same labels as the dual needles?

 

You already have the answer:

In case of a hydraulic failure, by switching the switch to the 2 position the pilot can see how much pressure is left in the Anc and EmB systems.

 

So, if the switch is set in up position (1 SERVO 2) the indicator shows HYD 1 & 2 pressure, if switch set to down position (Sdes F.S) the indicator shows ancillary and emergency brake pressure.

 

It's a small cockpit, so 1 indicator + 1 swtich = 4 hydraulic systems pressure read out :smilewink:

Nice!!! :mad:

 

The Damage Model is definetly here, all the systems are burried deep in the airframe and the hydro system is triple redundant, the hydro alarm will only light up when a certain amount of pressure is left (can't remember it right now). You're most likely going to loose a wing before loosing hydraulics.

If I read this, then the manual gets invalid and viceversa.

 

There are 3 pumps, 1 and 2 for systems 1 and 2 and EP only for system 2. There is no such thing as subsystems. All of this is according to the manual.

 

So I still dont understand anything from your post. As a pilot I depend very much on manuals to operate.

Servitudes is a subdivision of Hyd 1 which can be isolated (in cas of leaks).

"Servitudes" are:

- airbrakes

- slats (BECS)

- air intake scoops (PELLES)

- landing gear

- normal wheel brakes

 

Frein Secours use an accumulator on Hyd 2.

 

Electro pump is on Hyd 2 circuit.

 

The manual is under work, so it's a nuisance if all your questions end in complain about the manual.

Ok, the Hyd 1 has a subsystem, right? Which can be isolated in case of leaks so the aforementioned can be utilized. The EP keeps the Hyd 2 alive for flight controls and emergency breaks and landing gear in case of pressure below threshold. But what happens if Hyd 2 has a leak? The EP wont be able to keep up and you will lose flight controls. I know that wont happen, but how is it constructed?

[jojo]

The flight control servos are dual channel, fed by both HYD 1 & HYD 2.

 

If you loose both HYD 1 & HYD 2 you will have to walk...

[Joni]

Oh, ok. So I guess I should never have read the manual in the first place :D

 

All of this you guys know is documented or its just an educated guess?

 

I see all kind of professional answers in these forums and I dont know if you just know everything or if all documents are available. Although its been said many times that the Mirage documents are top secret, even Zeus told us that 80% of the module was made on a guess.
