Aircraft Evacuation

  • 14 CFR 25.803 – Emergency Evacuation

– Paragraph C

  • Must be shown that the fully loaded aircraft can be

completely evacuated in under 90 seconds.

  • Compliance must be shown by actual demonstration…

unless the Administrator finds a combination of analysis and testing will provide data equivalent to that which would be obtained by actual demonstration

Aircraft Evacuation

  • AC 25.803-1A – Emergency Evacuation

Demonstrations – 03/12/12 – Supersedes -1, dated:11/13/89

  • Limitations of current method
  • Computer modeling

–

  • 10. Computer Modeling. Work is being done in the field of computer modeling

to develop programs which could be used to demonstrate compliance with the evacuation demonstration requirements. Although progress has been made, to date, no program has been presented to the FAA and found acceptable as a substitute for an actual demonstration. Any applications for the use of computer modeling to demonstrate compliance with § 25.803(c) should be coordinated with the Standards Staff of the Transport Airplane Directorate.
