Some tool inputs may require engineering judgment to sort out scenarios that fit the AC guidance but may not be practical in the field. The engineer is responsible for the review of all tool outputs and their adaption to site-specific requirements, as necessary.

• Aircraft Characteristics Database
  For aircraft with a CMG and MGW combination in the TDG 2 category, use the ADG and TDG Classification Tool below to calculate TDG 2A and 2B.
• ADG and TDG Classification Tool (added 4/4/2022)
• Acute Angle Exit Tool (added 8/19/2022)
• Taxiway Fillet Design Tool (MS Excel) (updated 1/18/2023)
  • Taxiway Fillet Design Tool User's Guide
  • Taxiway Fillet Design Tool Instructional Video (added 4/13/2022)
• 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.

These drawings represent standards according to AC 150/5300-13. They do not substitute for engineering principles and judgement that adapt to every possible scenario. The engineer is responsible for the review of these standard drawings and their adaption to site-specific requirements, as necessary.
