The setup procedure using SID97 is a different issue. I think the more interesting question is does one monitor metered or unmetered fuel pressure in the cockpit. It seems that TCM and at least Coumbia (Cessna) recommend/use metered and that Lancair generally sets up their aircraft to use unmetered. I haven't gotten a good answer as to why and what the advantages and disadvanages are. Obviously the values are different, but they are measuring essentially the same thing. Can anyone comment on what advantage/disadvantage there is to using a metered vs unmetered source for you fuel pressure measurement while flying. Dan Ballin LEG2 #286
