    Thanks for the replies and the info that only 20 miles is not paved.
    When towing the interstates in the lower 48 I average 55 miles each hour by driving 60.
    Does the Alaska highway allow those speeds for the most part?
    Thanks Herman

    OK - will work on all this for a while. Then make my red line guesstimate. Thanks for all the input.
    I still have flashbacks to Physics 101, and all the Newtons, and other terms I cant remember, and my brain goes into shock!

    If you decide on the ferry, then try your best to go to Seward - Then you are there!
    Much better than driving from Haines.

    Herman...Unless there is something new, you can't ferry to Anchorage.
    There are few runs from Seattle or Bellingham to Seward
    All others go to Haines, leaving another 800 miles +- to Anchorage.
    I've driven many times. Four days sound about right pulling a trailer.
    I think I have beaten the ferry every time I drove. It stops alot.
    I've never rode it except to Kodiak to deer hunt. In state ferry.
    Besides road work, the only bad part of the road is @ 20 miles at
    the border on the US side, the entire way is paved.
    Regular gas is 462.9 here, more in Canada, @ $.25 less in Anchorage.

    Yup metric smeckret

    I started school on standard and finished on metric lol
    sure glad we still use standard barometric pressure in Aviation up here at least
    rather than the kilo-pascals like on the news lol

    yes sir,
    59 degrees Fahrenheit(15 Degrees Celsius) @ barometric pressure 29.92 @ sea level
    A perfect day

    The first formula was a standard formula,
    looking now I see I forgot to add that it was in MPH and oz/sqft

    Here it is again>

    stall speed = 3.7 * square root of wing loading

    speed in mph
    wing loading in oz/sqft

    that may help eh!

    That other formula
    Just use "lb/ft^3" for density altitude rather than KG/m^3
    the rest of the formula is relatively easy to convert to standard

    Just do each other calculation in standard,
    and use the above standard (lb/ft^3) calculation for Air Density ;0)

    Never been that way. Always figured 6 days minimum from Great Falls to Anchorage. Last trip, gas was $1.50 to $2 a LITER, and truck, trailer averaged about 6 mpg. Motels not cheap, when you could get one - and food was lousey most of the way! Got rancid roast beef in restruant across from Whitehorse Airport, and worst KFC in Whitehorse I have ever eaten!
    4000 miles - one way - from St. Louis.

    P.S. If you can get to TOK, Alaska before too late in evening, you can get the best food, and possibly a motel room, at FAST EDDIES.
    Great Beer-battered halibut at restraunt at boat dock in Seward, and more of anything that you want at KLONDIKE INN at Soldotna.
    One stop you have to make is the REGAL HOTEL restraunt at LAKE HOOD, in Anchorage (the name may have been changed) You can eat good food and watch float planes taking off right outside the windows.

    We had to start to endure it about then - forced to it for trade purposes. Ended up having to pack a set of American tools and a set of metric tools in my truck because it had both kinds of bolts in it. I think my French cousins, (and others) really stuck it to us on that!
    Now my plane has two sets, with a Jap engine and AN bolts in the rest!!!
    I was a machinist - used to working in thousanths, and ten-thousanths of an inch. Metrics were a pain to convert!
    It is a foreign system to us old-timers.
    I experienced being a foreigner in your country many times starting some years ago:
    I couldn't set the thermostat in my first motel room because is was Celcious - couldn't find anyone to translate it to Farenheiht for me either.
    This is life, and we just have to make the best of it. Lesson: Carry conversion tables when traveling!!!

    I could not find a number in my books to use for density of air at sealevel, 59 degrees F, if that is still standard day. Isn't that part of the formula - got to look at it again. If not, then disregard.

    If that 3.7 formula you first gave is V= meters per second, then maybe I can convert that instead of the 11 mph that I thought was wrong. 11 m/s = Back to calculator.... OK - came up with 24.6 mph, and that is reasonable.

    I guess I would fall under the later category then of being a foreigner, as I'm from Canada
    we gave up the standard system ... oh,roughly 30 some years ago

    I'll see if I can translate it for you

    It will cost ~$5000.00 and 4 days to trailer a Kitfox on the Ferry to Anchorage from Bellingham, WA..
    How many days does it take to drive and tow from Bellingham to Anchorage?
    Thanks Herman

    John, can you translate that into American? What is the "^"? (Nevermind that question: I know it must mean you couldnt print a little 2 or 3 for squared or cubed.) Old flyers dont use sillymeters - only drug dealers and foreigners use Kg.
    I would be glad to put this to use if you can put it into our terms.
    I know engineers and scientists also use those terms, but most of us are just flyers.
    But I garantee, that if I started telling how many Kilos I could put in my plane, the Federales would be all over me!!!

    Yes clean,in level flight

    The formula to calculate stall speed is:
    V = √( 2 W g / Ï S Clmax )

    V = Stall speed m/s
    Ï = air density KG/m^3
    S = wing area m^2
    Clmax = Coefficient of lift at stall
    W = weight KG

    The formula accounts for altitude being input,of the appropriate air density figure

    The term stall speed is misleading though,
    because speed really has very little to do with when a wing will stall

    Stall's occur because of angle of attack

    Stall speed, as calculated with the above formula only works for straight and level flight
    The wing will stall at a much higher speed, if the plane is maneuvering such as a steep turn as this will cause G-loading which in way increases the planes weight

    If you know the G-loading,
    then you can factor that into the stall speed formula with increasing the gravitational G constant

    either way,it can be calculated

    QUESTION for EX-Warp Drive pilots who switched to IVO IFA:
    If there are no sandbars or other tight places to get in and out of, how much would your take-off increase if you set a Warp Drive to the cruise pitch that your IVO sets at to give you that extra cruise speed? And, what do you think that setting would be?
    I realize that they are not the same prop - if you cycle from take-off to cruise on the ground, you could measure the differences in degrees.
    I am mainly talking about Soob, but other comparisons might be helpful.

    This would be clean, I guess? What about varing degrees of flaps? Is this at gross weight? Should be less at lighter weights?
    Lots to consider here.
    Thanks for formula. but it don't compute in my mind: Wing Loading of 9, square root = 3 x 3.7 = 11 aprox mph stall?
    What if your wing loading was 6?
    Wouldn't the Coefficient of lift have to be used in this calculation? It can vary from 1.3 clean to above 2.0 flapped.
    And how about Reynolds numbers in the formula? Lift slope? planform, etc?
    Seems to me, that there are a lot of variables in calculating stall speed: Don't see how one formula can fit all.

    Stall speed can be calculated
    stall speed = 3.7 * square root of wing loading

    This would be for straight and level flight in cruise of coarse,
    steep turns would increase the stall factor

    I once watched a video of some idiot - forget what monoplane he was flying - doing low-level loops. The final shot showed the trees coming thru the prop!!! Quite starteling - think he survived - plane didnt. Believe NSTB had the film.

    If that doesn't fix the leak, then maybe you could tap it out to next size, and use a reducer bushing, or buy the next size drain.

    Loctite and others make a paste Teflon thread sealer that is far better than the tape. The tape should never be used for any fitting. However, I don't know if the paste is ethenol-proof, and it certainly won't replace stripped threads. It is good on most metal fittings, but better is the Loctite Hydraulic sealer - think the number is 545, but will have to check on that. Teflon paste is good for air and water fittings, the hydraulic sealer is for fuel and oil fittings, and is good for anything.
    Best to go with what Doug recommended.

    I have a standard 3/8 line gascolator, but need to know if I need to go to the pressurized gascolator if I put my dual electric fuel pumps inside the firewall, between the tanks and the gascolator. My Holly carb needs 2 to 6 lb of pressure - certainly not the pressure that fuel injection takes.

    Also, Airdale used a 1970's or 1980's Ford 6 cyl pickup fuel pumps on Airfdale #1. Anyone know anything about them?
    Dave Johnson told me that the Facet would need rebuilding after sitting for the winter, and he started using one from Automotive Accessories, but I never got the model.

    DAR/FAA Question: In order to pass the airworthiness inspection, all instruments have to be marked?
    Well, I can mark my never excede speed (red line) my flaps operating range (white arc), and my caution range (yellow arc), and the upper part of my green arc - but not knowing stall speeds before testing, how can one mark the lower end of the ASI without flight testing first?
    Guestimate, and correct later???

    Dumbest show I've ever seen
    I admit, I'm a Discovery/Science channel addict.

    I've just watched the dumbest airplane related show I have ever seen. "Confederate Flying Machine" These guys "build" from period sketches a flying machine that was suggested by a confederate scientist/inventor. Originally to be built from wood/linnen and powered by some sort of steam engine these idiots built it out of what looks like steel racking frames with a wood wing covered by ceconite, a steam engine of who knows what design and a modern prop.

    When they achieve 700 rpm they determine it is enough to get this 600# thing off the ground (RC controlled thank God). It goes down hill from there.

    It was like a train wreck, I couldn't turn it off...
