- I've mentioned priority valves in the wrong sense. Actually **Priority valves cut off hydraulic power to heavy load users if hydraulic pressure in a system gets low.**

Cheers and Happy landings! :)

Nice explanation.. but you missed about.. ***priority valve***. Actually If a system pressure is low, the priority valve will cutoff hydraulic pressure to high load user such as flaps and slats, and the landing gear to maintain the operation of the essential flight control
Sagar Shrestha nicely picked out sir.... priority’s valve makes them close the valve not give them priorities
Its already there in description since a long time. Thanks anyway!
Good explaination
PTU becomes active when differential pressure is GREATER THAN 500psi. Thanks for the videos
Yes thank you
Lovely video... just one thing . In my opinion , in case of hyd Lo pr of a system , the priority valves cut off the supply to heavy load users to protect the little integrity left in the system and operates many low load items as possible. Please advise
+Amit Srivastava Oh I just saw the video! I think I said it the other way around! And yes you're absolutely right! 🙂 Thanks! Will mention in the description! Cheers! 👍🏼
Amit Srivastava priority valve only supply fluid to necessary systems only like primary control surfaces..it will not supply to systems like landing gear for which v have alternate source of gravity extension.
Great videos, hope to see more in the future!
Thank you
Can you explain about rat more. I understand that there is a fan which rotates due to aerodynamic force . After that whAt happens ....?..there is a electric motor or hydraulic motor in the rat which operates the blue electric motor . Plz explain about this . Thanks
RAT (rotates like a windmill) - drives a hydraulic motor - runs an emergency generator
Good job
Tks!!! Great videos.. as i said, there are very helpfull
You're welcome!
Pl correct ...Priority valve cuts of supply to users downstream of priority valve .there is spring in priority valve which cannot be pressed by the lowered pressure and fluid cannot pass the priority valve to less priority users.
Priority valves cut off supply to to heavy load users like landing gear, flaps, slats and emergency generator which are downstream of the priority valve.
Sir why don't we keep yellow pump off during single engine taxi and let PTU take care of situation?
To add redundancy so as to prevent a situation where if either green EDP or PTU fails then you're in trouble.
@@poh Thank You Sir
And Sir what is the reason Indigo Starts Engine no 1 during taxi and why not Engine no 2. (There is NWS and parking brake on yellow system)
I think priority value cut off power to heavy load users if hydraulic pressure in a system is low ( fcom).that means in green landing gear will not be available . You explained other way round .? Can u clarify if I am wrong
Yes, I had edited that long back on the description of the video. Shortly going to edit the video too!
What happen if we loss fluid in green reservoir? Can we deploy the landing gear.?
Yes use gravity gear extension.
As a convention always right side engines are started first ...whether it is Airbus or Boeing aircraft ...pls see..
There is no mandatory regulation. As a convention, yes we start right engine first.
I think , that for your parking brake coz u need yellow hyd ...
Thank you sir this will help me to understand the concepts even though have the materials, i am very lazy in reading books
You're welcome!
Pls do more videos
Explain the function of leak measurement v/v (LMV) as a maintenance POV.
I did not get your question completely.
Plz describe how PTU transfer power
It only presurizes , in case of pump fail( G or Y) .. u need to have reservoir fluid.. if reservior low level, u cannot use PTU...
Tu peut respecter un peu mieux l’anglais ? Tu roule les r et c’est horrible
Vous respectez rien aujourd’hui
Mais bonne vidéo, merci bye
