AutoBrakes
 

Like Bill said it takes wheel spin up for autobrakes to work. Perhaps the wheels didn't spin up fast enough on the ice for the system to acitvate?

Oh, yeah. I flew an airplane once that had a system with that exact same name. Since all airplanes with systems of the same name operate exactly the same, and since all airlines' procedures are identical, I can serve as a technical expert on the topic.


Ask me any question you want.




:rolleyes:

i know that i've jumpseated on SW and seen that they DO deactivate things like VNAV. not sure of the reason. i have heard that the VNAV will be activated (if it isn't already) due to fuel costs and being able to use the fuel-effciency features.

the rest of it, i don't know.

Read what was wrote bright spark. I never said it was an unsafe practice merely a method to allow the airplane to be turned faster, nothing unsafe about it. A few had asked why, I offered an opinion as to why based on how my airline conducts ops.

My previous post was edited. I wasn't refering to you about safety, chill. Try reading. the post under yours....

Like I said, I just don't understand how people think that safety is second to other factors...schedule, pay, fill in the blank. That's all.

Kill Bill,

SWA uses LNAV mode but as of yet have not used VNAV principally because the auto throttles are not activated and their current procedures restrict VNAV. SWA does permit VNAV in an advisory capacity only.

Makes me wonder when they may change their mind considering the price of fuel in todays world. Just in simple terms flying in chop or mountain wave, instead of chasing airspeeds constantly over time that the auto throttle could save significantly over purely manual adjustments. SWA however is a money making machine and that is a fact that must be respected in this discussion.

Well....guess that plane won't be having a short turn time, would sure hope SWA's priority is on safety over and above turn times...on the 75/767 aircraft RTO is the only autobrakes setting equal to max manual braking....sounds like this incident had weight on wheels issues as well

I recall that American didn't put autopilots in their airplanes (DC-6/7) until it was proven to save fuel.

Now, I'm young, and don't know much, but I thought that the RTO on the 737s set the brakes to MAX autobrakes if power is set to idle, which includes reverst thrust, so if the pilots saw that the plane was not deaccellerating properly, couldn't they just set autobrakes to RTO and thrust to idle?

Why would the autothrottles be deactivated to begin with? What would that gain anyone, aside from the annoyance of having to constantly set the power like you're an RJ?

Probably $$. Don't have to fix what you can't break.
