Nick:
Nice to see that someone insisted on the fuel flow gauges as an option. Why aren't they mandated by regulation?
There is no requirement to provide fuel flow, range or endurance information to the pilot - some manufacturers do, but some don't. Yet we hang people who run out of gas (if they survive).
So why aren't fuel flow meters required equipment? (hmmm - sounds like the subject for another column...)
And I meant that the fuel tanks indications were inaccurate in most cases, not fuel flow. Over a very long period, you can get a reliable indication of fuel flow from the fuel tank gauges, but not over a short period.
