What is this?

Here is an article from AOPA regarding flight time:

It really depends if your paying for your flight time or the one charging for the flight time.

Tom,
MD83Driver posted a great link. The airspeed switch on your '67 is pure genius, as it is meant to actuate at an airspeed right around take off, giving you the most accurate tach time to correctly log all your air time for airframe and engines. However, it looks like yours might be modified a little and may actuate in a strong breeze, if not cause some drag! I have attached a picture of what one looks like - the actuator paddle should trail, and when it actuates, it rests up against that little button on the lower wing skin.

Thanks Jeff! I will pay attention to it this weekend and see when it activates. It looks pretty original, but is obviously different than the image you sent. I cant find any comments in the log book, but that doesn't surprise me at all.

I totally understand the benefits of clocking only the flying time. Heck I need to remember to shut off the Foreflight log timer because it keeps on ticking even after the plane has stopped rolling......... But it doesn't start until you are on the takeoff roll so they got that right. Of course I may be missing some sort of setting to fix that too.
