This video is wonderfully explained by you sir, I am an aeronautical engineering student and watching this helped me understand all mechanisms for our calculations 🙌🏻✈

Is there any altitude limitation for landing gear extension.

@poh 5 ай бұрын

Used to be 25000 feet but now has been removed from the manual, simple Speed and Mach dependent.

may be a pair of wheel have to aply delayed break (cold break) after 5 -6 seconds

During a Gravity extension, with Green hyd available ( training purposes) On retraction will the doors close or remain open ?

Thanks for your cool and handy presentation about LG system. one suggestion, about Alternate Braking can you please give more info which i think missing here? Why and how its used?

@poh 2 жыл бұрын

Lot of information is missing! 😁 Alternate braking is with yellow hydraulic and is used when normal braking isn't working.

LGCIU change iver takes place after the retraction and not after landing. 03:35Videos are excellent. Good wirk!

@poh 7 жыл бұрын

+kun4able Yes you're right! Thanks for the correction, it's each cycle completion which is with retraction. Thank you 🙂👍🏼

hi, in the first diagram, what do you meant by Self maintained?

@poh Жыл бұрын

After departure it maintains hydraulic supply to the gear even though its up

Hello Sandesh, I have a seminar coming up which should be mechanical related, so is this topic related to Mechanical?

Hi, one question, the hydraulic pressure is cut off when the gear is secured and locked up? Because when I saw another video, the captain said that with the turns of the gravity system it depressurize the hydraulic system of the landing gears

@poh 4 жыл бұрын

Some pressure is maintained at the gear when it is secured and locked up. But most of the pressure is cut off because the uplocks maintain the gear in the up position. When you do the gravity extension the hydraulic is cut off completely because its not needed and can used for more important applications such as flight controls etc.

If landing gears are in extended position during whole flight will it have any impact on hydraulic systems?

You're welcome! And that would be more to do with an aircraft engineering background which I don't have. Sorry!

What’s the significance of self maintained loop ? When does the loop get activated ?

@poh 4 жыл бұрын

When gear is selected up on take off, the loop gets activated and keeps the safety valve open.

@sarathmanuel5234 4 жыл бұрын

Planes Over Head Thanks for the reply.Does that “syst1”on the landing gear architecture indicates LGCUI1 ?

@poh 4 жыл бұрын

Yes it does

@sarathmanuel5234 4 жыл бұрын

Thanks again. Incase of LGCUI1 failure inflight and then I do a go around ,will my landing gear retract then ,because now self maintained loop won’t get activated because of LGCUI1 failure right ? As per the logic diagram now the AND gate output is 0 and safety valve gets closed then and there . Correct me if am wrong .

hello sir~ your contents really help to me, i have one question about landing gear gravity extention, If the first clockwise isolates the green hyd and the second unlocks the doors, so why is the third one turning?

@akshaynagarmat6605 4 жыл бұрын

Third turn allows gravity to drop the gear into the extended position :)

@poh 4 жыл бұрын

Thats correct!

@Anshul1ish 4 жыл бұрын

Third turn will let the gears to extend by gravity and locks the gear so as to avoid aerodynamic force that can push the gears to unwanted position. I hope m correct sir.

With towing bar nose will can be turned 85 degrees, not 95 degree to each side.

@kurtnobrain 7 жыл бұрын

harith perera its 95 degrees as per the Fcom, please check

@poh 7 жыл бұрын

It is 95 degrees only! :)

@harith89on 7 жыл бұрын

kurtnobrain sorry it was my mistake, 85 is for towbarless operations. NOSEWHEEL STEERING (NWS) Towbarless operation on the nose landing gear (towing and pushback) is approved when using the accepted towbarless towing vehicles listed in the Airbus WISE ISI 09.11.00001, with the following information: Maximum NWS angle 85 ° // END

Hello Sandesh,what are the deceleration rate of low/med/max brakes in knots?

@poh 7 жыл бұрын

+rajesh gilda Deceleration cannot be in knots because thats not the units of deceleration.

@gildarajesh 7 жыл бұрын

I meant how many knots/seconds deceleration rate?

@poh 7 жыл бұрын

+rajesh gilda Deceleration is m/s^2 (NOT speed, this is change in speed by time) The unit of knots which is a speed itself is nm/hr. Knots/seconds cannot be a unit. There is no direct conversion like you want it. For information Med gives 3 m/s^2 and Lo gives 1.7 m/s^2.
