Section 5.1 Part B
Use charts for range or endurance power settings. Use 90-92 kts for best range
07 OIL CONSUMPTION AND CAPACITY
There are two oil tanks, one on each engine with 54 Imp gals capacity each. Working oil
capacity should be about 30 gal per side and if oil is less than 25 gal per side flight should
not take place except in extenuating circumstances.
Consumption of oil should be assessed frequently by dipping the tanks There are no oil
contents gauges
In-the absence of a directly observed consumption, use a figure of one gallon per engine
per hour as an 'expected' use
08 RANGE FLYING
Range Speed is dependent upon weight. At 28000 Ibs AUW the speed is 92 K kts.
The C of G should be as far forward as possible. The aircraft should be clean.
Use Carb Heat Cold unless icing is suspected.
Refer to charts this section for speeds, consumption and height to fly
09 ENDURANCE FLYING
Endurance Speed is the lowest speed comparable with aircraft safety and control. This
can be as low as 80 Kts but should be restricted to 85 Kts (Vmca)
Fly the aircraft as low as possible, but normally not below 1000 ft. The aircraft should be
clean, and G of G as far forward as possible Use Garb Air cold unless icing is suspected.
Refer to charts this Section for details
Unless Range or Endurance flying is being conducted the standard cruise power setting is
to be used:
