Alaska ETOPS...problems?

[alpine1989]

The data shows that SEA-HNL can carry between 151 and 154 (seasonal variation) adult pax based on 1.5 checked bags. With kids and less checked bags 157 is possible. HNL-SEA is no problem

LIH-SEA is going to be more of a problem due to LIH short runway and takeoff limitations. The data shows between 147 and 154 adult pax based on 1.5 checked bags.

ATA's B737-800 have 27K thrust. MTOW is 174,700 lbs and average OEW is 95,000 lbs. 2 Class config is 160.

I think the whole queston is this; are the figures Alaska is using based on the full ETOPS fuel requirements, or are they fudging based on using domestic fuel rules? This is the point that my source was trying to make.

If, as HalinTexas said, ATA is using all available power and flaps to get to OAK, how is AS going to go against the winter winds SEA-HNL, or worse, ANC-HNL?

On another note, I just heard that AS decided to make the ANC-HNL route year round (2x per week in summer).

ATA's B737-800 have 27K thrust. MTOW is 174,700 lbs and average OEW is 95,000 lbs. 2 Class config is 160.

I think the -800 max taxi is 174,700 with a takeoff of 174,200. If the ATA Planes have the Short Field Performance package (SFP) then Alaska will have much of the same lift problems they do. The Alaska -800's have the (SFP) and can lift more weight off a short runway then a non equiped -800. Any ATA guys know if their -800 have the (SFP)? I don't think they do.
Its true Alaska announced year round service from ANC but I think it is only 2 times a week.

I don't believe ATA has the "short-field package." Basically, because I've never heard of it. What is it? However, we have operated out of MDW, DCA and LGA since we got them.

There are many occasions when we need all 27k out of OGG, too, but it's not nearly as difficult as LIH.

I think the big thing on the short field package is the fact that the slats don't extend from mid to full until flaps 30 is selected. With the standard 737, the slats move from mid to full extend when flaps 10 is selected. That means with the SFP you can do a flap 25 takeoff with the slats at mid, which apparently is a big deal for short field performance.
I think there is also something about the roll spoilers extending to a steeper angle in the ground mode, but I'm not sure about that one. As a pilot, the slats are the only thing you notice because the thing is harder to slow down. There isn't the increased drag at flaps 10 from the slats being full down like on the standard model. There is also more of a ballooning when flaps 30 is selected.

The flight spoilers come up to 88 degrees I believe instead of the 60 normal during touchdown. It helps with landing data but the big thing is the diffrent scheduling of the leeding edge to get more lift / less drag at greater then flaps five takeoffs. Sould help some on the E-tops flights but they said they will still have to block some seats from Lihu I believe.

actually the Air Miles (wind corrected grnd miles) during the winter, are shorter on the ANC-HNL run vs. the SEA-HNL run. Winter month air miles are in the 2650nm vs. 2700nm range, or thereabouts.

I think that the kicker will be the winds. AQ had serious problems out of ANC due to winds, and had to send a bunch of bags through SEA quite frequently.
