Thanks, Rob, for posting the results. =C2=A0The ones that said "top it" did=
n't abide by the spirit of the question :-) in that I don't know how many m=
inutes of fuel that equates to, but there were enough replies in minutes. =
=C2=A0The technician in me couldn't resist doing some math:=20
The average planned fuel remaining was 63 minutes, or about 30 minutes in e=
ach tank. =C2=A0I guess that would work, but for me that would be about 7 g=
allons in each tank, at my low fuel warning setting. =C2=A0I know I would g=
et an additional verbal warning from my usual right seat crewmember :-(.=20
The standard deviation of the answers was 33 minutes, a fairly large variat=
ion considering the average was 63 minutes. =C2=A0A significant number of p=
eople would have in the vicinity of 30 minutes remaining. =C2=A0In fact, 4 =
out of 12 would have 30 minutes or less. =C2=A0One planned the flight with =
only 20 minutes remaining.=20
Of course, if I knew the minutes remaining of the ones that said "top it" t=
he results would shift dramatically.=20

Thanks to those that responded to the fuel question. This is how it was=20
worded:=20

There is 30min of fuel in your plane.=20
You wanta meet your friends for lunch on this stunning VFR day.=20
You don't have any planned flights for the next few weeks.=20
The lunch stop's gas is the same price as as at your home field.=20
The lunch stop's runway is 5,000 at sea level.=20
The flight time to lunch is 30mins=20

How many mins of fuel do you add to your tanks for the flight?=20

Here is the summery in the form of:=20
