A ? for Boeing and Airbus guys...

I did see a performance calc that required a 1 minute fuel dump for a return We were heavy that day.

Of course it's PIC discretion, so I start as many as I'm told

>330k 4 motors
300-330 3 motors
<300 2 motors

As a side note, it costs the company $20/min/eng during taxi out. I sure enjoy having my CBA complied with....

There's no "proper" sequence we use, on the classic we have an electric pump for brakes on HYD4 and use the ADP on 1. All F/E controlled. None of this "Automagical" sissy stuff. (At least til this fall )

With the classic we have the steel brakes, so they get hot, and it shuffles fast with 4 turning at light weight.

Have the body gear steering MEL'd yet? It's freaky to feel it hop in turns!!

Sounds good to me. The -400 is the same way, there is an AUX pump on 4 and the ADP for 1. Light weights are tough with all four turning but the carbon brakes don't get too hot. We let the speed run up to 30 kts then one brake application back to 10...then 30...then 10...etc. With the carbon brakes we worry more about brake wear than the heat. One application is one application whether slowing on landing or slowing down on taxi.

I've only had the BGS MEL's once but it wasn't my leg so I didn't get to feel it. For a big airplane it turns on a dime with the BGS.

I will usually #### two down on the taxi in if we are light but lately I haven't had any long taxi times to really worry about it. Being light isn't so bad on the RR powered aircraft but the P&W runs away quick. We were 393,000 kilos out of Honkers yesterday so we didn't have much choice in the matter.

Plastic airplane just like Diamond. You can do a search for Diamond or Cirrus Sucks and get a few opinions on the matter of plastic airplanes.

What's a pack?

[B767Driver]

A PACK is an air conditioning unit in a jet. I believe it stands for "pneumatic air conditioning kit"...but maybe I'm making that up.

The PACK works by the compression and expansion of air...thereby causing cooling in the process.

A PACK consists of heat exchangers, a compressors and a turbine. Engine air from the compressor is routed to a heat exchanger to for cooling and then is compressed by the compressor. A second heat exhanger cools the compressor air before it is routed to a turbine. Here the air rapidly expands and cooling is the result.

And the 787 program shows exactly why Boeing should leave making kiddie toys to Airbus.

See, I always thought it was PACK as in Pressurization and Air Conditioning Kit.

You're probably right...I really don't know for certain.

As for the original question, I think someone answered it for the Embraer Jets already. If we elect to use Engine 1 for single taxi, we just wait till the tow bar is disconnected and everyone is clear before we start it. System 1 hydraulic pump can be a bit noisy and annoying.

Airbus seems preety metal to me, and Boeing has had far more aircraft technicalities then Airbus, I think? Someone confirm, that is what I heard.

Ah, but from what I was taught during upgrade, UOE and my Line Check, the company is wanting us to start #2 on the push back and taxi out that way every time (unless a 2-engine taxi is required). They're discouraging guys from waiting to start #1, just crank 2 and as soon as the towbar is off, away you go.

By the way, I was taught that PACK is Pneumatic Air Conditioning Kit.

It's Pressurization and Air Conditioning Kit, as when you have no packs, you depressurize

Composites are the wave of the future. It is what fiberglass is to metal. Its lighter, stronger and a lot more expensive.

And harder to test for stress, hoo hoo!

I hope you enjoy my new avatar Doug since you failed at finding a 24oz Coors Light.

[Doug Taylor]

I tried bro. But we were at the Paris so it was kind of a challenge to find the large canisters of Bourgeoise brew! Ask Mrs. Taylor, I tried!

[SeanD]

I know
BTW I have some tshirts for you and the mrs.

[Doug Taylor]

Sweet. BDD stuff?

[SeanD]

Yeah, found some normal sizes. Ill see about popping them in the mail this week.

[Doug Taylor]

Hardcore.

Personal opinion: But if I know I'm going to be in any sort of line-up for departure, and I see people seated in our zone 4, no way I follow this. The pump back there is that annoying. Sitting back there myself in a line up I thought it was worse than being at the dentist. Please of please tell me you don't subject people to this during the 9am bank out of EWR.

[OldTownPilot]

I was subject to "the pump" for a 1.5 hour ground stop sitting in 14C (it was a 135, so it was still the last row). I really didn't want to be a wise ass and tell the FA to tell the cappy to kill the pump. For my heads sake I probably should have.

I think that is worse than 8 hours on an airbus on the ground in JFK with a TV.
