Richard Carper, former owner of navion N4529K:

Hi Mike,

Per your request I made couple of cross country flights to check speed and fuel consumption. They are amazingly like my big blue bird. Your plane is about 2 mph faster than mine,, which I would expect as yours is new and mine had 1500 or s hours on it, and more antennas. The fuel consumption was as nearly identical as could be. The flight numbers are below.

The plane sure flies like my old bird. I just Love it!!!

Flight 1, First leg CVO to Columbia River, 116 miles, elapsed time=53
takeoff, climb to cruise at 5500;
2200 rpm, 22 inches manifold pressure;
leaned to 60 on FF Gauge;
IAS at cruise=134 mph,
TAS=142 mph,
fuel consumption=11.6 gph,
avg. gnd speed made good=131 mph

Second leg Columbia River to Port Angeles, 135 miles, elapsed time=56
Climbed to 7500 cruise;
2200 rpm, 22 inches manifold pressure;
leaned to 60 on FF Gauge
Fuel consumption=10.7 gph
Avg gnd speed made good=144.6

Trip 2. CVO to Burns via Bend VOR. 225 miles, elapsed time=94 minutes
All at cruising altitude of 8500 feet;
2200 rpm, 22 inches manifold pressure;
leaned to 60 on FF Gauge;
IAS at cruise=131 mph,
TAS=144 mph,
fuel consumption=10.2 gph,
avg. gnd speed made good=143.6 mph
Interestingly navions were operated from aircraft carriers during the Korean war.
I recommend setting field of view to 60 or 70 degrees instead of the default 45 degrees when using 3D cockpits, this helps the overall effect a lot. field of view is in the rendering options menu.

The Navion airspeed indicator is in Miles per hour, as opposed to knots. Back in those days, all private aircraft air speed indicators were in statute miles per hour. The use of knots is relatively recent, in the 60's or 70's - since IFR became common in general aviation. however if Miles per hour is confusing to modern pilots, you can go up to the settings menu> data output, and put the speed on screen in knots.

The engine controls are accurately tuned so dont forget to use normal procedure to increase blade pitch as you accelerate and also as you gain altitude. Normally prop  blade angle is set at minimum pitch (blue lever all the way up) for takeoff and landing to provide maximum power. During cruise and at higher altitudes the blade pitch is increased to the best angle for most efficient cruise. You can turn on inflight data output to see very detailed information and help understand the relationship of different engine settings.

Please note: As of 8.60, austin has changed autopilot usage, if using 8.60 it is necessary to set one of your control stick buttons to autopilot disconnect, and also read the new autopilot procedures as listed on the 8.60 new features at x-plane.com.
