Re: Draining fuel tanks
Despite the drainable quantity when stationary being discussed here I believe the recommendation for "main tank useable fuel 9 gallons" should still be followed for C-85 and larger engines in flight. It's a required placard for Model 19's and F-19's in TCDS 1A9.
When the Gilberti/Harer/CAP C-85 STC is installed, and a new dial fuel gauge in the cockpit replaces the former external wire/float unit, the new fuel gauge reads "E" (Empty) when about 3 gallons still remains in the main tank.
Also note the current fuel flow CAP Service Bulletins for STC SA1-210 here: http://dc65stc.blogspot.com/2010/05/...c-sa1-210.html. I haven't found a reference for useable main tank fuel in the STC but might have missed the note somewhere.
And as Hank notes big honking tires up to 31" are approved with the proper wheels and brakes so pay attention with minimum fuel aboard.
