A319 landing question

[airplane wizard]

I flew into Denver last week and it only showed 125mph on final approach on the direct tv gps map. Do they fly final at stick shaker to save $ on brakes?

 

[Mama's Boy]

Probably groundspeed.

 

[Bringupthebird]

Yes, I know I shouldn't be the one to admit it, but yes that's the reason: Brakes. Given the high cost of brakes it a calculated risk worth taking. Sure we might lose a jet now and then, but maybe we won't. And if we don't shouldn' we maximize the return on our risk by saving those brakes. Plus we hit fewer bugs, necessitating less Windex.

We also takeoff slower thanks to Sully's experience in the Hudson. If we fly slow enough we can fly in formation with geese rather than through them!

BTW- What's a stick shaker on an Airbus?

You berry funny man

 

[Captzaahlie]

No, don't play it off all the stuff Bringing up the bird said is absolutely true!
I'll find the memo, I don't think I threw it out.
I usually leave those memo's on the coffee table to impress my wife's friends.

Actually, Airbii are capable of flight without engines and can fly as slow as they want. The whole fuel thing and flying around in a pattern is just to screw the customer more so we have more money to spend on chemgoo.

...he said "stick shaker"!!!

 

[Mike man]

He is the airplane wizard after all, maybe he can figure it out.

Since most 320 family Airbus have stick shakers he is probably right...idiot.

 

[Captzaahlie]

Enough FI for now, going to get my stick shaken....

If the airbus doesn't have a stick shaker, then how are the pilots warned of a stall?

Stall speed can be less than 100 kt, so you weren't anywhere near it. And LTV gives you groundspeed anyway, not IAS, so I wouldn't go shooting approaches off it. Or making assumptions of pilot technique from it.

Anyway, there are other ways to keep out of a high alpha regime without a shaker. The Airbus has a number of protections built in, so the pilot can pull full back on the stick and get maximum performance without approaching a stall. Simply put, the pilot can't stall the airplane, since he can't reach an alpha high enough to stall. If for some reason alpha gets high enough to approach a stall, the autothrust system commands TOGA thrust to power out of an impending stall. If some flight computers or some combination of required sensors are inop, the pilot actually can pitch into a stall by overriding a preemptive pitch down command by the remaining flight computers, but in that case an imminent stall warning screams at him first. In really degraded operation, he doesn't get a pitch down command, but he does get the scream. The recovery procedure is as you'd expect: TOGA thrust and adjust pitch to stay out of a stall.

Are you a pilot?

It is imposable to stall a 320 family Airbus operating in NORMAL LAW.

You can however stall a 320 in any law other than NORMAL, if you approach a stall the AWU will yell STALL, STALL, STALL.

You do know 320/330/340/380 Airbus have only side sticks, and they are not interconnected.

I don't know... how are you warned of a stall on your copy of MS Flight Simulator?

 

[Tweaker]

You guys are harsh today!

 

[airplane wizard]

Are you a pilot?

I am but can't get a medical

....Realy. AB AC have "stick shakers"....Better study-up for your next oral DA!!!..The only STICK SHAKER in the Airbus is during LAV BREAKS!!!

I haven't used MS Flight Simulator since the DOS version in the mid 80's and my computer at that time didn't have sound. So, the nose just dropped and it started spinning regardless of rudder input.

The airbus can stall in normal law.

Have you ever flown at flaps full alpha max and then retracted the flaps? I wouldn't try because it only prevents the slats from retracting (alpha lock)

Also..full rudder in one direction followed by full rudder in the opposite direction is not approved and would cause a stall at low airspeeds.

What do you mean "have you ever"? Who the hell would do that? Wait, there was those guys in Buffalo and we know how that turned out...

Also..full rudder in one direction followed by full rudder in the opposite direction is not approved and would cause a stall at low airspeeds.

Actually, I think it isn't approved because doing so can cause the rudder to get torn off, ala AA out of NYC.
