WingX 2.0 User Manual - FAASafety.gov

By entering any two of the three values, WingX will calculate the third.
Example: The time to cover the 324 NM at 150 knots is “02:09:36”. This
time was automatically propagated down and assumed to be the ‘fuel time’. By
entering “12” in the “FPH” text box (i.e. 12 gallons as the Fuel Per Hour),
WingX calculates the fuel required for that portion of the flight as 25.9 gallons.
Note that pounds may also be used as the fuel units. We use gallons in this
example.
To determine endurance for a specified fuel load, enter the number of gallons
(or pounds) and the Fuel Per Hour (FPH) value and WingX will calculate the endurance in HH:MM:SS.
IFR Climb Rate and Climb Angle
IFR climb rates and climb angles are critical for safe flight in non-visual conditions. IFR departure procedures
are designed and published with specific criteria and these are printed right on the departure procedure.
However, the requirements are provided in terms of climb rate per NM, but this is not easily measurable in the
aircraft and neither is it easily determinable during pre-flight preparations. By entering the required climb
gradient as published on the departure procedure, as well as the calculated ground speed, WingX will accurately
calculate the required climb rate in feet per minute (FPM) and the climb angle in degrees. Using this valuable
information, pilots can carefully monitor the climb performance during the climb to ensure that the minimum
climb gradient is being achieved thereby significantly increasing the safety of the flight.
Example: If the climb procedure specified 300 ft/nm as the required climb
gradient and we were capable of a ground speed of 120 knots, then the
required climb rate is calculated to be 600 ft/minute with a climb angle of
2.83˚.
Time Sub-page
Times are everywhere in aviation from logbooks, to FARs. WingX makes adding, subtracting as well as Duty
Flight Time calculations easy.
Adding and Subtracting Times
Times can be added or subtracted using either format HH:MM:SS or decimal hours.
