N31AK POH, Pilot Operating Handbook
Differences between N31AK and typical LEZs
The empty weight of 927 lbs is "a little heavy".
The wt was reduced a little in Sep 06...
engine is O-235 L2C (M), meaning it is an L2C with high compression.
The conversion to this configuration was performed by Lycoming.
It's 125 hp (less than the 160 hp of the common O-320 EZs)
The tires are the large type mentioned in the Rutan POH; these plus
the springy nose gear are the best possible for landing on non-paved
runways. see Burt's POH. These are 5x500 and take 40 psi.
The plane can handle "soft IFR" (no ice, Tstorms). ILS, VOR approaches.
It has a working Loran but its database is very old.
The auto pilot includes a wing-leveler. You can make turns with its knob.
The auto pilot can track to a VOR, or to its Loran, or level the wings.
There is no "Avionics Master" switch in the plane so you have to turn off/on all boxes yourself.
The plane has a shorter nose than many EZs. Might make it .001 more stable.
It has no (built-in) GPS but there are two handheld GPSs, a Magellan 315 and a Garmin 196. The Loran is better than you'd think.
I removed the crankcase relief tube's connection to a blocked oil/air separator. This was regretable because the escaping oil ends up on the rear of the cowling.
The canopy can't easily be opened by a passenger.
An LED lights when the left tank falls below 3 gallons. Another LED lights
when the right tank is below 4.
The fuel efficiency (mpg) seems much lower than advertised (so far).
Pillow cases are kept in the strakes to help hold goodies.
The original Wt&balance was made (wrongly) w/ nose retracted.
"gyro" switch on rt panel turns on heater fan
The gyro in the autopilot is always powered (when master On).
