Jeff,

I think that is a really bad idea.  If you have some crud in the tank you just switched to, you are looking at an engine failure or at least an engine stumble right at takeoff.  At a minimum you are looking at a new pair of underwear :)

The instructor that transitioned me into low wing aircrafts (Mooney) from the Cesna 152/172's trainers I had flown up to that point really beat this one into my head.  My rule is that the tank that is used for runup is the one that is used for takeoff -- no exceptions.  I prefer to select the tank before engine start and leave it there till the first tank change in the air.  And I too prefer to change tanks within gliding distance of an airport in case there is any crud in the tanks or other problem associated with the fuel, the tank or the selector.

Regards,

Hamid

Dave,

 

I start on one tank and after taxiing to the hold short --switch tanks & depart. This seems to reduce the fuel switching issue.
