Description/Instructions Date
FAARFIELD 1.42 FAARFIELD 1.42 is the standard thickness design software accompanying AC 150/5320-6F Airport Pavement Design and Evaluation. FAARFIELD 1.42 replaces all previous versions of FAARFIELD. 9/18/2017
COMFAA 3.0 (Updated 8/14/2014) COMFAA 3.0, as introduced in version B of AC 150/5335-5, is the recommended method to determine airport runway, taxiway, and apron pavement strength with the Aircraft Classification Number - Pavement Classification Number (ACN-PCN) method. The software is capable of calculating Aircraft Classifications Numbers in accordance with the International Civil Aviation Organization (ICAO) procedure.
  • Support Spreadsheet for COMFAA 3.0 (MS Excel, 1.1 MB) (Updated 8/18/2017)
    Facilitates flexible and rigid pavement information required in COMFAA 3.0 for PCN calculations.

3D Airspace Analysis Program (3DAAP) Version 5.0 9/19/2006
Backcalculation Software (BAKFAA) (Updated 10/13/2017) For backcalculating FWD data and computing airport pavement load responses by layered elastic analysis. Use with AC 150/5370-11, Use of Nondestructive Testing Devices in the Evaluation of Airport Pavements. Version 2.0. 5/2012
Geodetic Calculator (Zip) Updated version of GEO83.  
Runway Exit Design Interactive Model (REDIM) REDIM is a computer model developed to locate and design high-speed runway and right angle exits at airports. The model uses kinematic equations to characterize the aircraft landing dynamics and a polynomial-time dynamic programming algorithm to find the optimal locations of the exits. The objective of the optimization algorithm is to minimize the weighted average runway occupancy time (ROT) of an aircraft mix selected by the user. A database of aircraft characteristics by Aircraft Approach Category (AAC) has been included in the model to facilitate its use in a large variety of airport environments and conditions. The program is a technical planning tool. 4/13/2020
Taxiway Fillet Design Tool (MS Excel) For calculating the minimum recommended centerline radius and pavement edge geometry for lay out taxiway turns with "non-standard" deltas. See the Taxiway Fillet Design Tool User's Guide (PDF) for instructions. 5/2018
