A Day Without Fire



And there you have it!

A No 1 Fuel Tank indicating zero. No fuel, no combustion, flame out!

I enjoyed this particular incident because it's not every day that anyone can jokingly claim that they flew back to mainland on an empty tank. Too many fingers would point at you for bad fuel planning, bad airmanship and a host of other skull-impacting insults. 

But you would also see the amber captions which traces the fault to a No 1 Fuel Probe, which is like the fuel sender in the No 1 Fuel Tank. Faulty sender means faulty fuel quantity indication.

With 310 kilograms of fuel in the No 2 tank and a connecting flange sitting above the 228 kilogram level between No 1 and No 2 Fuel Tank, hydraulic laws would mean that the fuel would equalise between tanks. This means that the No 2 tank indication was equal to the fuel in No 1 tank till the fuel drops below 228 kilograms in No 2 tank.

It was an interesting day, having theory being demosntrated in real life, and trusting the whirly bird to get us home.
