One of the things I love about VAF is that it seems that I learn something new everyday. I probably enjoy the Point A vs. Point B topics the most, since I seem to learn the most from them. For some reason lately my attention has been diverted to Fuel Selector Valves and I have learned a few things.
1) Normally aspirated engines generally do not require a return line.
2) Fuel Injected engines generally do.
3) Andair vs. all others
I have noticed that in every conversation I have observed to this point all the possible tank selections are Left or Right. I get the distinct impression that BOTH = Bad, or at least, not discussed and I am wondering what the Pros and cons are. I am currently training in a 172 and it has BOTH. It seems to work well. I worked on F-15's and F-22's for 30 years and they don't get a choice (its BOTH by the way). Having no data it is hard to form an opinion myself, so I am soliciting input.
Hopefully I haven't waded into a "Nose-wheel vs. Tail-wheel" or a "To Prime or Not To Prime" topic. If it is one of the 'Stern Verboten' topics, I apologize in advance.
