Airbus A320 Training Video - Hyd Sys G+Y Failure

[cptgaget]

Can somebody help me. I want to know what the are the alternate sources of hydraulic power if the main system fails? Thnx

[JonRDow]

@cptgaget Is it the ram air turbine?

[anarquia0203x]

excuse me, all pumps (G EDP AND Y EDP ALSO ELECTRIC PUMP) HAS FAILED?? so the blue system operate with one just only engine run!!, the RAT deploy when both engines 1 AND 2 has failed and two main AC BUS POWERS has failed; this is happens above 100 knots, my question is does airbus T/R (thrust reverse how operate it???

[Yanndooms]

Way have the pilots to shut off GPWS flap mode? The flaps can be lowered by gravity so why?

[JonRDow]

Its to do with approach speeds and the limitations of the slats and flaps

[mcgalcri]

They will land with Flap3, if you dont shut off the GPWS in overhead panel, you will hear a constant alarm in landind config.

[almasrik]

@Yanndooms A G&Y Hydraulic failure calls for a Flap 3 landing. GPWS Mode 2 warns of a landing with the aircraft not in landing configuration (flaps not in Full config). Since this type of emergency calls for a configuration 3 landing (Flaps 3), the A320 is equipped with a warning inhibit switch for such emergencies to prevent nuisance warnings from distracting and annoying the pilots....Hope that helped.

[mrcpetroni]

in this double hyd failure flaps are lost!

so you have to hinibit GPWS flap warning feature that is triggered when you try to land with flaps "not in landing configuration" (""TOO LOW FLAPS")

ps. when PF call for flaps is because the system need to have the flap lever in pos.3 but flaps don't move.

[yahul25]

@Yanndooms G+Y Hydraulic failure results with no hyd supply for flaps. Slats are still available with the BLUE system but they are slow. N FLAPS can NOT be lowered with gravity. So u have to put GPWS Flap mode off or else it'll start screaming at short finals that TOO LOW FLAPS !

[jpunteney]

GPWS flap mode switched off to prevent spurious GPWS "Too low, flaps" warnings on final approach when landing with abnormal flap configurations. Flaps cannot be lowered by gravity, landing gear can.

[darsh198]

@Yanndooms flaps can never be lowered by gravity, landing gear only,,,

[simplefact4u]

@Yanndooms A year old reply but its for others seeing this as well. Hence the recommended flaps level was dictated by automated check list the GPWS flap mode is off to prevent the warning alert for flaps against terrain/altitude under this circumstances. prevent distraction to pilots and record un-required data in Flight Data Recorder :)

[trooper744]

lol that guy sounds like chekov LMAO

[nmatthews210]

Under normal circumstances does the airbus stay in normal law when gear is down or does it switch to direct law?

[JonRDow]

Normal Law, with Flare Law at 0-100ft AGL (would have to check FCOM to confirm this)

[yahul25]

@JonRDow Direct law on gear down only if in Alternate law previously.

[mcgalcri]

Yes. Only direct law when the plane is in alternative law (normal law without protections) and Landing gear down.

[almasrik]

@nmatthews210 For pitch control, Flight mode (Normal Law) starts blending into flare mode (pitch demand law) at around 50' AGL. Lateral control remains in normal law until 0.5 seconds after touchdown, after which it blends switches to ground mode.

[yahul25]

@almasrik 0.5 or RATHER 5 SECONDS I GUESS SIR.

[Airbus320Training]

@nmatthews210 the moment the gear is down, it goes into direct law

[crazymonkeyVII]

i didn't hear them talk to atc (atc notified is supposed to be in the checklist right?)

[Yanndooms]

Does anyone know what direct and alternate law is?

[GusanoNavarro]

Airbus has protections programmed into the fly by wire system, as a pilot you can't stall the airplane, you can't roll over the airplane and most of all you can't do anything that exceeds the safety envelope that is called "normal law" but in certain failures degradation of the flight controls occur and there are 3 levels normal, alternate & direct law. These are the laws that govern the flight controls given a specific scenario. :)

[depechetwuh]

if flaps failed on status pages how did they get flaps to run

[a340313x]

in case of flaps fail its possible to extend but not to retract

[icoddelosvinos]

this vid shows the professionalism of todays pilots. i always feel save when flying...

[benfalas]

What actually does and for hwat is for the hydraulic sistem?

[dfuenzalidag]

I´m not an airbus pilot, but in most aircraft the hydraulic system can control brakes, flaps, spoilers, ailerons, autopilot and even more. In case of failure, all of these systems has a back up system and a pressure accumulator. Very safe to fly today!

[DeltaEagle7700]

Wow! Very professional pilots! Airbus is a great aircraft. Imagend what would happen if all 3 hydraulic systems fail.

Uh-oh!

[yahul25]

@DeltaEagle7700 RAT EXTENDS, N U GET THE BLUE SYSTEM BACK PROVIDED UR ARE ABOVE 100 KNOTS.

[kadiloros]

very good videos,very professional pilots!just one thing!these are the old sops!some airliners may still use them but the majority uses the new ones!be good!

[seanlee747]

Love the "maneuver with care" ECAM message.

[Boeing757basher07]

Very Very Good bunch of Educational Videos you have here, Xtremely Professional Pilots in the flight deck, Brilliant post, 5 *

[flybywire350]

cindex54 ...... I believe that the RAT (coupled to a hydraulic pump) powers the Blue system, and not the Green system.

[JonRDow]

Well done, you are right, just checked the FCOM and it does indeed power the blue hydraulic system.

[flybywire350]

Thanks very much!  Great video, btw!

[uploader1010]

are you a pilot urself ?

[cindex54]

Hmm, I think the A320 Hydraulic system is slightly different than the A330 Hydraulic system. In the A330 FCOM, it specifically says "A pump driven by a ram air turbine (RAT) pressurizes the green system in an emergency."

Sorry if I get anyone confused...

[cindex54]

Actually, this thing has 3 hydraulic systems and it even has Ram Air Turbine to power the Green system, which is the backbone of the Airbus hydraulic architecture..

[JonRDow]

Absolutely correct.... Just imagine a HYD G+Y+B Failure

Mechanical Law anyone?

[pazu888]

Mechanical back-up is amazingly still quite easy to manoeuvre, we managed an ILS approach and landing in the sim in Mechanical back-up the other day!

[GusanoNavarro]

I imagine that was in the sim!!

[baristheguitarrist]

you will never have the time in the air to speak out these things... never... trust me :(

[jimbotrains]

true, very....... a real pilot would b doing to much to try to talk. and he would have to think what he is doing.

[hffin]

I don't get it, if the flaps don't work, how can they extend then? Can 1 hydraulic system supply hydraulic pressure to all systems?

[zanza448]

this is a work done by 2 Cpts of TAP Portugal in the past year 1997!!

[Agent92]

How did you get this? Are you a pilot yourself?
