The new Seneca fives have a DDMP part of which is a very accurate fuel to end readout in time. It is very tempting to keep pulling back the mixtures to get the endurance you want
Fuel flows normally come back to around 12 US gals per hour at a setting of 29 man 24 rpm and are fine tuned on the TIT gauges.
With 123 USG tanks they are good to fly for 5 hrs to dry tanks or 4 hr legs.
Legal carrying capacity is poor but is more to do with an engine out capability than what the aircraft can carry.
The actual fuel guages are notoriously unreliable. and I dont think I have flown one with good guages.
I can remember flying with a new Seneca five pilot who was not intrument rated at the time from Luton to Cannes. With headwinds the DDMP was showing 15 minutes fuel left at Cannes. The poor inexperienced pilot could not understand why I insisted we divert into Grenoble for fuel
The DDMP is very accurate.
