Feeling overwhelmed trying to remember and understand everything about flying? Shoot a text on Telegram @CaptainSQa320 t.me/CaptainSQa320 and I will add you to a private group where we will discuss on everything from being a new pilot to being a full-fledged Captain. This group will be useful for those who are preparing for their Pilot Interview and Training. You can clear your doubts with pilots around the world and accelerate your learning curve. It’s free! See you there. Cheers! Telegram t.me/CaptainSQa320

Flight mode changes to flare mode below 50 ft.

[@Captain_SQ]

Excellent Raj.

[@klausdiefenbach8329]

As a former A320 pilot, now retired, I found your presentation to be very well done. It dusted off a few of my now rusty “little gray cells“

[@Captain_SQ]

Thank you Klaus, I do appreciate your comment.

[@cacobesoain]

Very good examples to describe the sensations of flying in these flight conditions. Thank you very much, now these serious problems that can happen to us in flight are understood in an entertaining way. Be appreciated

[@Captain_SQ]

Thank you.

[@quaxky326]

Thanks, I was just about to fly my airbus. I wasn’t sure how to fly it, but this video helped explain me the protections it has. I’m pretty experienced, learned everything from KZbin, but yeah, thanks.

[@Captain_SQ]

Glad it helps

Smart Lynx Estonia Flight 9001 ended up being in mechanical backup for pitch only after the THS override mechanism stopped detecting pilot input to he trim thinking it was computer failure and kept shutting off the ELAC’s. Pilots kept resetting preventing failure until they didn’t and due to a design limitation with the SEC’s the aircraft just went to mechanical backup

[@Captain_SQ]

thank you for sharing.

[@luiskrohn]

Excelent explanation 👍

[@Captain_SQ]

Thank you.

[@HarryAviSky]

So what causes the aircraft lead to mode mechanical back up Capt ?

[@Skyboy320]

At 09:44 it’s Mach 0.006

[@KingMagician985-zo3hn]

I have an example of a mechanical backup law: it's smartlynx base training accident have a good one

[@jitendrasingh-xo7ts]

Thanks buddy.

[@Captain_SQ]

most welcome.

[@NevadaOOO]

How do you change an A330 to direct law in mid flight? I’m trying to get it to work in Xplane12 but lowering the landing gear doesn’t do the trick.

[@AviationShots._]

Flare mode at 500 ft?? It's below 40 ft.

[@Captain_SQ]

Yeap ,not 500ft. Apologies

[@AviaZou7A]

I have a question, why would Airbus change it's Flt Ctrl Law if the plane is in the situation *Airbus Industrie 129 *XL Airways Germany 888T *Air France 447 *Air Asia 8501

[@peteconrad2077]

Because the aircraft doesn’t have the data required to support normal law.

[@deanangelo5148]

When and why would you change laws? And how would one “activate” or change laws

[@Captain_SQ]

Hi Dean, we will be flying with Normal Law with all the available protections. Only when there are certain failures, it gets downgraded to Alternate Law then to Direct Law. It is also highly unlikely for the aircraft to only have Mechanical Backup controls unless it is a severe failure.

[@9LimaAlpha7]

what is "THS" ?

[@sgroriccardo]

Trimmable Horizontal Stabilizer

[@nimishdahake1526]

Hello capt, is mechanical back up a law or a mode? The A320 has only 3 laws right? Also do we have mechanical linkages in their aircraft? Thank you

[@Captain_SQ]

Mechanical backup is a mode where you only control the rudders and pitch trim mechanically.

[@nimishdahake1526]

@@Captain_SQ thank you!

[@Captain_SQ]

@@nimishdahake1526 my pleasure.

[@nicolashernandezcastrocolo1843]

So i cant use roll in mechanical backup?

[@JETA14]

You can roll using rudders

[@Captain_SQ]

Yes that is right. Secondary movement, or using differential thrust, if available.

[@poblanoaburrido80]

Change into flare mode is not fron 500ft. but 50RA down to 5 seconds after land wuen again chainge into ground mode.

[@dba6121]

A pilot will only face mechanical backup situation once.

[@100NUMARALIADAMMM]

350ft

[@dayanand1190]

Nothing could save AF447. Airbus's design philosophy or implementation of systems is very wrong.

[@peteconrad2077]

You’re wrong. Following the Airbus stall recovery still would have saved it.
