Flight distance
[Example]
Obtain the air distance when the air speed is 180 knots and the flight
time is 40 minutes.
[Operation]
Align 18 on the outer scale with the SPEED INDEX (MPH) on the inner scale.
Then, 40 on the inner scale corresponds to 12 on the outer scale.
Thus, the air distance of the flight is 120 nautical miles.
Rate of fuel consumption
[Example]
Obtain the rate of fuel consumption (gallons / hour) when the flight
time is 40 minutes and the fuel consumption is 140 gallons.
[Operation]
Align 14 on the outer scale with 40 on the inner scale. Then, the
SPEED INDEX (MPH) on the inner scale corresponds to 21 on the outer scale.
Thus, the fuel consumption is 210 gallons per hour.
Fuel consumption
[Example]
Obtain the fuel consumption required for a flight when the rate of fuel
consumption is 240 gallons per hour and the flight time is 1 hours and
40 minutes.
[Operation]
Align 24 on the outer scale with the SPEED INDEX (MPH) on the inner scale.
Then, "1:40" on the inner scale (time scale) corresponds to 40 on the
98
outer scale. Thus, the fuel consumption is 400 gallons.
