FDP Calculator

FTL Calculator - SIMPLE
FTL Calculator - SCHEDULE

FDP Calculator is a simple tool for planning crew duties in accordance with Flight Time Limitations (FTL). It is divided into two tabs: SIMPLE and SCHEDULE

In the SIMPLE tab, FTL is calculated based on:

  • Start of duty - the reporting time for duty,
  • No. of planned sectors - the number of sectors planned for one duty,
  • Split Start - STA of flight preceding split,
  • Split End - STD of flight following split.

In the SCHEDULE tab, a specific AOC can be selected (if more than one is defined in the FTL Settings), and schedule details can be inserted for a quick calculation of the FTLs. Additionally, the calculation can now use the AOC assigned to a specific aircraft. To see the calculation for the AOC of the aircraft that the crew member will operate on, set the AOC field to “Default” or “None”, select the required tail in the Aircraft column, and add the flight legs to be evaluated. The calculator will apply the AOC assigned to that aircraft. Flight time suggestions while setting STD and STA times will be provided based on the aircraft's performance model.

Basic FDP length is calculated according to the Max FDP table implemented in Leon (as per operator OM-7).

Basic duty includes reporting and post-flight duty times and is calculated based on MAX FDP.

Latest time on blocks is the latest allowed Block On Time, calculated as Basic duty reduced by the checkout time.

The following FDP variations are included in the results:

  • Standard Crew - max FDP for standard crew,
  • FDP+ - max FDP with extension,
  • Double Crew - max FDP for augmented crew.
All times are displayed in Local Time (LT), based on the time zone to which the crew is acclimatised.
