Although the main focus of this AC is on engine inlet probes, the methodology can also be applied toevaluate temperature probes, combined pressure and temperature probes, and static pressure probe behavior regardless of installation location.
2.

scale emergency evacuation demonstrations, and (2) use of analysis and tests in lieu of conducting an actual demonstration.

Guidance is provided for the following: • Required Navigation Performance Approach (RNP APCH) procedures; • Barometric vertical navigation (baro-VNAV); • RNP 1 (terminal) operations; • RNP 0.3 (rotorcraft) operations; • RNP 2 domestic, offshore, oceanic, and remote continental operations; • RNP 4 oceanic and remote continental operations; • RNP 10 (Area Navigation (RNAV) 10) oceanic and remote continental operations; • Advanced Required Navigation Performance (A-RNP), and • Additional Capabilities.

The guidance in this AC has been reviewed for suitability as an acceptable means, but not the only means, of compliance with the Airship Design Criteria (ADC), document FAA-P-8110-2.

This document notes when guidance is considered applicable to the ADC requirements and cross-references the applicable ADC paragraph with the 14 CFR part 23, subpart E paragraph.

Appendix B of this AC contains a list of applicable acronyms. 1.2 This AC describes an acceptable means, but not the only means, for you to gain airworthiness approval for aircraft data link system equipment.

This AC assist airports in complying with the laws and regulations regarding individuals with disabilities by: (1) identifying the relevant statutes and regulations affecting airports; (2) presenting the main features of each of the statutes and regulations; and (3) listing sources of assistance or additional information.
