    A "thingamajig will straighten things out. As you get older it becomes a Whatsitcalled. Nev

    Don't confuse Limit stops with Pitch control selection positions. I have difficulty determining what is actually being referred to. CS is Not the SAME as in flight Manually adjusted Pitch which stays at the Position you set it to.. The Fine Pitch Limit stop (in the Prop Hub) is set so that the engine does not have to Be revved too high for you to be comfortably above the Planes stall speed IF the Prop fails to full fine . Nev

    The First production Jabs had KFM motors in them which ceased production and Rod Stiff had to make his own Motors as he didn't ever want to have to depend on other engine manufacturers again. Nev

    Boeing 720

    facthunter commented on red750's aircraft in Airliners

    Same fuselage cross section as the 3 engined B727. The B 727- 200 version was a lot Longer and carried More Pax a bit faster. Nev

    FAR away CUE? Nev

    It's satire. Belongs in the Off Topic section.. Nev

    Small regionals will require a subsidy to Keep Operating. Their seat /Km cost figures are way up on say an A 320. Nev

    Spill mercury in a big aluminium Plane and you will write it OFF . It forms an amalgam with Metals some of which end up with little strength. Not very good around People either. Nev

    In earlier times Engines were not capable of being feathered. and Most Twins would not maintain Height on one engine. It was just accepted that is the situation. Later it was Made a requirement by Airwothiness Bodies but Many are still Marginal when at Max Wt. for the conditions. You Must also attain and keep at or above the VMC(a) airspeed to maintain Control. or you will have to reduce Power on the good Motor till you do. You have to "Milk the Mouse" to fly a twin at Max Wt on one motor just after Lift off. Stall is Below Vmc(a) in all cases I am aware of. Naturally any twin that flies ok on one engine goes real good on 2 . Nev

    The one with the throttle between your Legs? They actually get along pretty smartly. First Jab I flew at Lethbridge. Owned by Gary Baume. Nev

    You have missed the point entirely . Disappointing since I've gone to a lot trouble to explain the circumstance where things happen and why. How about reading my posts fully. Powered Planes are there to carry things so by your Logic the Less you carry the More efficient it is . The object is to Move PAYload efficiently to be profitable. Nev

    Pure AL has a fairly good resistance to corrosion As the Oxide Protects from further corrosion. Look it up and also ALCLAD use. It does need looking after as does almost anything else. Bronze is pretty good( Copper-tin) and even pure Fe. made In a Puddling furnace and wrongly called Wrought iron these days. If you know what to look for you'll find it on old shipwrecks used on the chains and anchors. The metal appears layered because it is. It's folded and welded under the Hammer, many times.. Nev

    Good work. It's Not that easy on line. Nev

    There are Plenty of Metals more corrosive than aluminium, It has been the Main Metal used in aircraft construction since Planes were Made We are having corrosion problems in steel tube frames of Aircraft. .Nev

    It doesn't have to be woven strands. Even covered copper wire corrodes. (verdigrese) . Insulated solid bar is fine. Some Welders and Motors use al windings, Bad electrical connections of any kind cause electrical fires, House wiring is single strand. Nev

    Aluminium is an alternative to copper. Nev

    Gliders trying for speed carry water to UP the weight. Maintain BEST Lift AoA means faster airspeed needed when heavier than when you are Light. If you are already faster than needed, go higher. It was answered a while back but further consideration doesn't hurt unless we start wandering away from the essential Principle of wing efficiency . Low wing loaded Planes have too Much wing except when taking of and landing and at Service ceiling which IS ? Lack of Power comes into that as well. Fixed tri gear and fairly low cruise speed of the Musketeer means to go higher is better Nev

    There's always the Old trick of moving the Battery further back and the advantage of that is you can calculate exactly how far you have to move it before you do anything. Being a fair way from the CofG (long moment arm) it has a lot of effect.. You have to start Nose heavy though. Adding/moving a weight that is not a part of the Plane is a waste and Last resort. Nev

    Isn't that what the prop extension is ABOUT? Nev

    Yeah Internet and You tube, All Good. The TRUTH now is there's practically NOTHING left that you can trust. We must get about 5 hoax calls a day. A lovely world we have Built for ourselves, which has SO much Potential till it all gets corrupted in no time flat. Nev

    Life's a BEECH they say. They have MADE some Pretty good planes. IF you can afford them. Nev

    Done a few C/ME/IFR renewals in the Duchess( B 76.) Cost me many $$$$'s. If you have less than 1 G, the stall speed is lowered and so is the DRAG and also the control effectiveness.. The extra mass of engines on the wings makes spins much More risky. DON'T go there. Nev

    Parasite drag decreases in thinner air. Most of the Drag relates to lift Generation. These are very high wing loaded aircraft and have a surprisingly good L/D ratio. General principles apply to ALL planes. A lot of planes have too much wing at higher speeds at lower levels. Nev

    Every aerofoil has a Cl max and that will be achieved at a particular Angle of Attack. Lets just say it's 6 degrees from the zero lift angle (which may be negative) If you are NOT at the Best angle you are Losing efficiency. If the angle is More than optimum it becomes unstable. If less Not so. You adjust by adding Power or flying at a lower Level. Many tend to fly too high to get a claim on the higher cruise level. Nev

    Yeah! Pretty scary and Irresponsible. You Programme something that is capable of modifying that Programme. Madness. nev
