| Subject: | Re: Running tank dry |
Hi Bob,
A little delayed I know but I thought I would share my experience with running
a tank dry. In October I (with my wife) flew our Lightning from our home in Horsham
Victoria to Perth WA for a round trip of some 3000NM (plus sightseeing).
On the way beck we had one long leg from Forrest in the middle of the Nullarbor
to Port Pirie, north of Adelaide and I decided to run one tank to close to
exhaustion to get a good handle on my fuel situation. In the event, about two
minutes before the clock said zero fuel the tank ran dry. The engine did not
cut dead but ran really rough and probably was not putting out much power.
You will understand that this is my impression in the five seconds or so it took
me to flick on the fuel pump and change tanks, I didn't stop to take notes
:).
In the event we covered the 530 mile leg in a tick over 4 hours with around 50
min fuel remaining which I think makes the Lightning a fair to middling cross
country aeroplane. Overall we did 33 hours flying at 130kt TAS, 24lph fuel and
just under one liter of oil all up. We had friends in a C172 XP accompanying
us and they were 10 knots behind on speed and 10 lph ahead on fuel used.
I think it an advantage that you don't have a "both" option on your fuel management.
If you have both tanks on the engine stops when the first one runs dry
and you then have to fiddle about turning tanks off to isolate the empty one by
trial and error. Not a good idea.
