Makes me wonder how Lindy made it to France... Now, not that I'm agin'
gadgets, actually I love em... But, if you start with the tank(s) full
and you have a watch, you have all the equipment that aviators have
used to calculater remaining fuel since Wil-n-Orv started the whole
ball rolling...
Let's say that having the fuel flow meter allows you to improve your
fuel burn by 3% overall... How many decades is that to generate a net
return on the cost for the flow meters?
