General Description

RFM-Pro is an electronic flight bag application that runs on Apple iDevices. It allows the user to determine performance chart results such as max weights in and out of ground effect.

The user may also optionally run weight & balance calculations.

Many other features are included:


An optional Airport database can be added, see below


Multiple aircraft can be installed on one handheld and selected from a pull-down list.

 RFM-Pro methodology complies with

bullet FAA regulations
bullet JAR-OPS 1
bullet EU-OPS Subpart G, Performance Class A
Airport  Database Runway database provides:
  1. Departure and Arrival weather lookup
  2. Barometric Pressure
  3. Field Elevation
  4. Temperature
  5. Real-time METAR

Field and Cruise Conditions The initial screen of RFM-Pro allows the user to enter pertinent weather and field information. These values are then converted as necessary (degrees F to C, for example) to allow performance chart interpolation.




Weight & Balance W&B is integrated into RFM-Pro.

The specific seat and baggage configuration for the user’s aircraft is displayed.  Clicking the M, F or C button to the left of the seat layout, then click on each seat to place a male, female or child respectively. An ACTUAL weight can be entered for any seat or for passengers outside of the standard weight model, such as athletic team members.

The user simply enters the weights corresponding to the bag stations and the new gross weight and CG are displayed. Fuel weight is also entered in a similar manner though a fuel moment "lookup" table is utilized.

The resulting CG  is then displayed graphically within the operating envelop for the aircraft as a small dot. The CG shift resulting from fuel burn is displayed as a line leading from the CG symbol, passing through the landing CG and terminating at the zero fuel CG value.  Values outside the acceptable range are shown in red.



The GRAPHICAL W&B allows the user to use standard weights for men, women and children.   Notice in the pictures to the right, that a numeric keypad appears for easy entry and that LBS appears in the selected seat.

The winter and summer weights are toggled by the user or automatically by date, both of which the user sets. 

AC120-27E Weight & Balance compliant

Using the standard weight module also allows full compliance with the recent AC120-27E circular. The W&B information (T/O Weight, CG, CG Limits, CG envelop, %MAC, zero fuel weight and passenger weight) can be printed utilizing the email function. 



Crew names can be saved within the software and included in the W&B. Fulfills  FAR § 135.63  Identification of crew members and their crew position assignments..





Performance Charts Performance charts for the aircraft are listed by phase of flight and possibly anti-ice or runway condition.

Clicking the appropriate category toggles the choices available .

When target values are assigned for takeoff distance, the chart is automatically and repetitively run to render not only the result based on the current weight, but the max weight allowed to still meet the distance or gradient respectively.

Landing Distance Factors (None, 80% or 60% and 15%) in compliance with Opspec C082 are included.

The TOLD card can be printed utilizing the email function.

Shown is the PPC for an S-76.  Your printout will contain charts that are unique to your aircraft type.
