FAASR3D – 

FAA Structural Analysis in 3D 

• Visual Basic.NET library. 

• Replaces obsolete NIKE3D 

Fortran program. 

– Managed Code - compatible 

with Microsoft .NET memory 

management services. 

– Improves performance. Old 

code was subject to memory 

conflicts and crashing. 

– Freely distributable code. 

• Continued updates to 

improve speed & efficiency.

Four Functions in FAARFIELD 2.0 

• THICKNESS DESIGN – Compute 

required thickness per AC 

150/5320-6. 

• LIFE – Compute structural life 

for a given structure and traffic 

mix. 

• COMPACTION – Compute 

subgrade compaction 

requirements per AC 150/5320-6 

for a given structure and traffic 

mix. (Applies to completed 

designs.) 

• PCR – Compute Pavement 

Classification Rating (PCR) for 

the structure and traffic mix.

FAARFIELD 2.0.0.e RC 

FAARFIELD 2.0.0.e RC Is the evaluation version of the FAARFIELD 2.0 airport pavement 

thickness design software accompanying DRAFT AC 150/5320-BG, Airport Pavement Design 

and Evaluation. 

FAARFIELD 2.0.0.e RC (Release Candidate) is the evaluation ver5ion of the airport pavement thickness design software accompanying DRAFT AC 150/5320-6G, 

Airport PaVl!ml!nt Design and Evaluation. FAARFIELD 2.0 features: 

A completely redesigned graphical user interface (GUI) with improved screen flow and explorer-based navigation 

A new :m finite element computational library, FAASR30 (FAA Structural Response - 30}, written in Visual Basic.NETTM. 

Support for the new ICAO ACR-PCR system {planned to replace ACN-PCN). 

New graphical vehicle editor provides the ability to add, save and edit user-defined vehicles. 

Updated aircraft l ibrary. 

Ability to work with multipli!!: jobsjsl!!:ctions at oncl!!:. 

Notes: 

FAARFIELO stands for FAA Rigid and Flexible Iterative Ela.stic Layered Design. FAARFIELD 2.0 incorporate.s full 3D finite element respon.se.s to aircraft Loads 

(for new rigid pavement.sand rigid overlays). The 3D finite element model.s u.sed for rigid pavement designs are computationally intensive and may re.suit in 

Long run time.s,depl!!:nding on the computer charaneristic.s. We would appreciate your comment.s concerning thi.s program and your .suggertions on how it 

could be improved. 

FAARFIELO 2.0 runs on Windows TM operating system.s. Windows 7 or highl!!:r is fl!!:commended. Pll!!:ase follow installation instructions in the rl!!:adme fi ll!!:. 

Point of cont.act: For questions, comment.s or further information concerning this program, please cont.act Dr. David R.. Brill, FAA Airport TechnoLogy R&O 

Branch,ANG-E262. 

FAARFIELO 2.0.0.e RC is an !!!:Valuation version and i.s not currently an FAA design standard. To download the current standard software FAAR.FIELD 1.42, use the
