.... I'm learning something new everyday in this business!
Seems like I have a whole new line of powersettings to try out now. (I'll check the engine and prop-manual first ofcourse)
It'll be interesting to try out WOT and lower RPM when flying at cruise at my favorite cruise-powersetting and altitudes (55% and 5-10.000')
Paul: even though most European countries use metric by now, here's how it is when it comes to planes in the majority of the Euoropean countries:
Altitude: feet
Speed: knots (mph is for cars and NOT planes

)
Altimeter: millibars
MAP: inches
Temp: (OAT,EGT/CHT etc) Celcius
Lenghts (wingspan etc) meter and centimeter
Lengths of a flown distance: NM (SM is for cars and NOT planes

)
Quantity: litres
FF: litres per hour
Weight: kilos and tons
Pressure: (oil/fuel) PSI
Pressure: (tires) PSI or BAR
ATC language: english and the local language
These are just some units I remember right now, so there might be others that I've forgotten.
There are also some variations to these units in some countries.
Confusing...?

naah... it's just something to get used to...
