    This outfit lost another one not that long ago.

    The fact that the “conveyor” of faberic had no (none, zip, zero, nada) effect on the takeoff roll dispite any concern that the conveyor’s speed may have been a bit too slow, fast or whatever makes your counterpoint inconsequential.

    The thought/point that the material my have not matched the exact initial speed of the aircraft and THAT is why the aircraft tookoff is comical. Rather than pick apart visual clues perhaps some folks should spend more time learning basic physics.

    I think on the next mythbusters they should prove that the only reason that the space shuttle takes off is because the launch pad matches the rotational velocity of the Earth EXACTLY. We all know if the launch pad didn’t rotate with the Earth the space shuttle would sit helplessly on the pad with engines blasting. Oh the humanity!!! Earth = largest moving conveyor ever!!

    FTL (Flight Time Limitations) are basically no more than:-

    100hrs in 28 days
    900hrs in 1 year

    Both of these limits are “rolling”.

    In the US it’s 8 hrs per day (scheduled, not actually flown) 30 hrs per 7 days (rolling), 100 hrs per month (not rolling), 1000 hrs per calendar year (not rolling).

    Duty Periods shall not exceed

    55hrs in 7 days
    95hrs in 14 days
    190hrs in 28 days.

    Again these are rolling limits. I am sure there’s an annual limit of something like 1950hrs but I can’t locate it.

    Man, those are some great rules. I wish the US had duty/fatigue rules like this.

    The US domestic duty rules are up to 14 hours scheduled per day but it can be extended to 16 for mx or wx. Minimum rest is 8 hours between block in and block out (total @#$%). That’s about it. No limitations on total duty in a week, month or year.

    The winglets don’t save fuel per se, as in reduced burn. The burn at any particular flight level is almost the same with or without. They cause the wing to produce more lift (or to lose less), thereby allowing higher flight levels earlier in the flight, and generally (normal winds) the aircraft burns less fuel at the higher flight level.

    Actually that’s exactly what they do, reduce fuel burn. Less drag = less thrust required = lower fuel burn.

    Yes, getting to cruise faster and being able to climb higher sooner helps but the fuel savings isn’t seen until mission length pushes 1000 nm (per the Boeing webpage) which indicates that the fuel savings is coming from that extended time flying at altitude rather than short hops.

    It takes more than a couple of years payback.
    There are 3 elements to the cost.
    (1) The cost of the Winglets themselves.
    (2) The cost of the mod kit for the existing wing tip (Some beefy structure goes in instead of the closing Rib). The mod kit and the fitting are more expensive than the winglet.
    (3) The down-time of the fitting, which can mostly be done during the scheduled maintainance periods, but not always.

    the most important element:

    (4) The price of fuel.

    With fuel prices so high every small percentage of savings adds up a lot quicker when fuel is $4+ per gallon vs. <$1 years ago.

    in reply to: The 10 scariest runways! #526508
    Whiskey Delta

    I wouldn’t call most of those scary. SXM has nearly 8000′ of runway with an approach over open water. Doesn’t push the limits of aircraft or pilots to handle that.

    DCA is scary in that if you bust the 2 Prohibited Airspaces to the north you are tracked by NORAD and missle defense systems. Again, 7000′ of runway with only a sharp turn to landing on runway 19 (which has several visual/instrument pieces of equipment to guide you in). But beyond the airspace limits which are well documents with landmarks to pick them out it isn’t scary at all.

    Only 1 of 4 runways at JFK is less than 10,000′. Runways 13L/R have sequencing lights to guide you in visually from the south in VFR conditions. Again, unusual but not scary.

    Talking to pilots who have flow it I would agree with Toncontin Airport being on the list. Not to mention that the type of aircraft being flown into these airports make a lot of difference. Perhaps a 747 into Matekane Air Strip would be scary but a C172?

    Great pictures and trip log, thanks for sharing. What lenses are you using? Under your screen name I see 400D so I’m guessing this is the camera used?

    3 of the 8 crew members died unfortunately.

    For those who believe peak oil will be coming sooner than later, how long can Hawaii’s tourism industry last since more than any other place, is reliant on air transportation? (i don’t think too many people want to take a boat ride there)

    They do get a number of cruise ships daily to the islands but I agree that the oil prices are hurting the islands. They ran a story on the news here last week talking about the skyrocketing prices for food in Hawaii. A gallon of milk was $8 and orange juice was $14 a gallon. Everything isn’t quite at those outrageous levels but just the price of eating is WAY up.

    Because a few airplane fans are also rail fans? 🙂 I was raised by one of those. 😀

    … especailly seeing as the US doesn’t seem to of been able to make it work with the failure of MaxJet and EOS

    http://en.wikipedia.org/wiki/Midwest_Airlines

    Midwest Airlines has been doing it for over 20 years.

    I think the fact that Mr. Hunt wants to blame a few analysts rather than oil prices is a sign that he’s keeping his head in the sand about what’s really troubling Silverjet. He needs to develop a real world view and see that energy costs are killing the airlines. Somehow he thinks Silverjet is immune to the skyrocketing fuel costs? Time for a new CEO…

    That’s the man and registration. I’m curious to the history of his specific Hurricane. How was is lost, etc. Again, just curious.

    Jim Pennington. He already registered a registration number that ended in JP.
