REFLECTOR: One hundred miles per gallon

[Al Gietzen]

trying to keep us in the dark Al? :-)

 

No; I just didn't want everyone to know about my bounced, crooked takeoff.
But, darn; now I'm going to have to explain:-).

 

The runway at my airport was lengthened on the south end by 1000 ft or so at
some point; and there is a 'bump' and the junction.  If 36 is the active
runway, that's about the point where the plane is getting ready to lift - so
the bump puts me off the runway - but it settles back down; and with just a
bit of cross wind - well you get the picture.  So that's what happened
Sunday when Chuck and friend came to have ride with me.  No big deal really.

 

Now, on subject - I can generally get 21 mpg at about 160 - 165 KTAS at say
8500'.  Now I'm motivated to see how much more than that I can get.  (I have
a mpg readout on the engine monitor, so it's easy.)
