Navajo 325 Cruise speed & fuel burn?
Gidday team,
If anyone has a Navajo-325 manual handy (or the figures firm in their memory)
I am wondering what sort of cruise speed you would get at, say, 8000'.
Power settings?
TAS?
Fuel burn?
Have a bit of time in Chieftains but the Navajo is supposed to be faster
and if we're only hauling 5-6 that sounds better to me!
Cheers

The PA31 -325 is basically a Navajo.
It evolved from the PA31-31 we all know but the major difference is that it is a C/R version with slightly more powerful engines.
The Lyc TIO-540-F puts out 325 HP (242KW) vs the 310HP (230KW) of the normal Nav.
So with an extra 30Hp total that should give you one or two kts extra and better T/O performance.
At 8,000', expect around 180Kts TAS, (deduct 1Kt per pax or 100Kg of payload).
Power, typical 31" x 2200 RPM should give a fuel burn of 130 - 140 total Ltrs/Hr with conservative EGT settings, maybe better if leaned as per POH.
If you're already driving a Nav or Chieftain, no big changes for you.
As with a Nav, a VG kit is essential to making it a useful aircraft, unless you're flying really short sectors and don't need to tanker fuel.

Thanks starlight
Have over 1100hrs in the -350's but zero in the smaller machines, and it was all 5+ years ago.
A friend is considering buying an aircraft and we are considering the figures for various models of Navajo, the main question being:
"Since you lose 2 places in the smaller aircraft, is there a saving to be had in higher speed and lower fuel burn?"
Over the sectors we are talking about (approx 160nm) the answer appears to be "maybe"
