Dan and Jon -

I read Jon's original email that he was using his Garmin to set up the  
fuel injection system. Thus my answer was to get help and if not, to  
comply with the SID. My apologies if this was the wrong starting point.  
However - the advice remains the same: use the proper gauges to set the  
system and then compare their readings with whatever indicating system one  
is using (Chelton, Garmin, Grand Rapids ...) If that indicating system  
permits a calibration, the baseline gospel would be the figures set by way  
of the SID and the proper gauges. One could then monitor metered or  
unmetered with the knowledge that they are above the redline specified in  
the SID when their cockpit indicator says so. One "WAG" told me that if  
you have to get rid of one gauge/indicator, it would be fuel pressure  
because it provides the least information upon which to base a decision.  
Fuel flow would be better in their opinion. I'm not sure if this rationale  
is enough to make the decision as to which pressure to monitor.

Dan: Where does TCM recommend using metered fuel pressure?

Cheers,

John Schroeder
