Biggest lesson I've learned????
Check "Everything" yourself, before committing to the wild blue.
Case in point: Chief pilot tells me to take a/c to X. I pre-flight and find there's 40% fuel onboard.
Chief Pilot: That's plenty, no need to top up. Go now to beat the light.
Duh! ok............. off I go. Pulled out a chart which still had course etc to X from last time......bye bye.
Weather/Wind was quite a bit different from last time (funny that).
Had me sweating golf balls when the low fuel came on with 10Nm to run.
Chief pilot on the phone later...........yeah that's alright, you still had 10mins fuel onboard. I do it all the time, no problem.
I should have: Checked the current weather, checked the burn rate in this different machine, insisted on topping up (would have taken 10mins max).
Stans 3rd to last paragraph summed up this CP to a "T".
I learned not to let others lax ways become my own........ Lest they kill me.
