Me, I absolutely hate to put my trust in an indicator. That stems from the THIRD flight in my very first airplane. The pitot tube thingie hadn't arrived yet, and with very little time in the airplane, the Mud Daubers plugged the pitot sometime after my second flight in the airplane. Since that day (and several thousand hours later) my faith in the airspeed clock in any airplane I've flown has been as a reference for comfortable verification of the seat of my pants ONLY. While shortly after the incident I realized it was "no biggie" that day, it sure seemed like I was in REAL TROUBLE for a while there. When (and in what manner) do you think an airspeed gauge would go South on you? Right. If you "feel right on final" and you glance at the airspeed and it says "15", chances are there MIGHT be something wrong there, eh? Especially since a -12 won't fly that slow. Put no faith in a gauge that may lie to you at any moment, no matter how rare. Sure, you should always "believe your gauges when IFR"- but VFR in our kind of airplanes, you're asking for trouble if you're "flying the numbers" instead of "flying the airplane". Mikey, you should have the feel of your -12 after 30 years. Just fly it in over the fence with almost no lift left in whatever configuration you got at the moment and plant it in whatever attitude trips your trigger. What if my airspeed reads 7 mph FASTER than yours?
