REFLECTOR: Interior foam

[steve korney]

You could carry more fuel but, your take-off distance wouldn't change if you 
carry more fuel.



Best... Steve

Sid,

When I flew to Vegas, it was on an instrument flight plan - so it was about
235 nmi., If I remember correctly, I averaged about 135-140 kts one way
(with headwinds).  Try climbing to 11,000' with 4 on board - it's a slow
process that took time. Taxi, holding for instrument release, vectoring at
LAS, all took up some time and fuel too.  Two hours at an average burn of
10-12 gallons per hour = about 20+ gallons used. With only 30 gallons on
board, I had just about 45 minutes left (required reserve).  When I get down
to 5 gallons in each tank, my "Low Fuel" annunciator illuminates (because
that's where I set my VisionMicro to go off).  What if I wanted to take a
trip with 4 people for 3 or 3.5 hours - couldn't make it without re-fueling.
Now, if my plane was lighter - I could carry more fuel, use less runway,
etc. etc.

Kevin,
I am not understanding your numbers...
1)  you report a fuel burn-rate of about 15 gph.
2)  the distance from PHX to LAS is about 222 nmi.   For a two-hour trip,
that gives an average speed of 111 kts.  This figures to about 7.4 nmi/gal.

3)  My guestimate of the power required to fly (my Velocity) at 111 kts is
about 66 hp ;
    hp = (5.5 gal/hr)   x   (6 lb/gal)  /  (0.5 BSFC)  =  66 hp
   This figures to about  111 / 5.5 = 20 nmi/gal.
