To play it safe I did an extended flare over the numbers, that's because I had two dead jet engines and had to dead stick without flaps, SOP. How about you Dan? Ken |

The turn coordinator and ASI are for that. The magnetic compass is useless during a turn, as you *should* know. Dan (whose IFR rating lapsed eight years ago already. Too busy fixing airplanes for other people. Where does the time go?) |

LOL, http://en.wikipedia.org/wiki/Spirit_of_St._Louis You should REALLY study how that was done. BTW, I use a Barometer as an altitude indicator driving around BC, up and down. Ken |

Back to the incident, my point is one can do IFR with a compass and a barometer, I learned that for IFR. Of course it's easier now, with radio. Lindbergh was NORDO. IIRC correctly he did careful navigation, reset his altimeter relative to sea level, and did some stellar and solar navigation to reset his magnetic compass. I thought every IFR pilot knew how to do that. Why the evident "spiral dive" ? Ken |

The compass, because of lead/lag and northerly turning errors, will not indicate accurately in anything but steady, straight-ahead flight. In a coordinated turn it will stay level inside its case and cannot be used for bank or pitch information. It will swim all over the place during turns, acceleration deceleration. Barometers are sticky and wholly inadequate for accurate altitude. Just being inside an aircraft cabin, whose pressure can be substantially different from that outside due to leaks in the fuselage, will make it read falsely. Inside a pressurized cabin it's useless, of course. Anyone who follows nothing more than a whiskey compass and a barometer in IMC is going to die real soon. Dan |
