This advisory circular (AC) presents basic information on wake vortex behavior, alerts pilots to the hazards of aircraft wake turbulence, and recommends operational procedures to avoid wake turbulence encounters.

This AC is issued to assist pilots with their regulatory obligation to see and avoid other aircraft.

This AC provides guidance to launch or reentry operators on how to complete the launch and reentry collision avoidance analysis in accordance with 14 CFR § 450.169. This AC discusses: 1) the contents an operator should provide to the Federal Aviation Administration (FAA) to satisfy Appendix A of part 450 for the collision analysis worksheet, 2) how to submit that information to the processing entity, and 3) proper vehicle operator responses to the analysis they receive from the processing entity.

Provides guidance material which may be used to determine the adequacy of barometers used in the calibration of aircraft static instruments and presents information concerning the general operation, calibration, and maintenance of such barometers.

Title 14 CFR uses the term Collision Avoidance System (CAS) or Traffic Alert and Collision Avoidance System (TCAS) to describe what Title 49 of the Code of Federal Regulations (49 CFR) and the international community has named ACAS.

Each of those organizations has called for industry and government to come together to develop guidance to help aircraft operators avoid conditions that cause turbulence and to help aircraft operators minimize risks when aircraft encounter turbulence.

Provides guidance material for the airworthiness and operational approval of Traffic Alert and Collision Avoidance Systems (TCAS II) and Mode S transponders. Like all AC material, this AC is not mandatory and does not constitute a regulation.

You can also use the guidance in this AC for seeking airworthiness approval for TCAS II version 7.0 (V7.0) certified to TSO-C119b, Traffic Alert and Collision Avoidance System (TCAS) Airborne Equipment, TCAS II and associated Mode S transponders.

This advisory circular (AC) describes acceptable means for showing compliance with the requirements of Title 14, Code of Federal Regulations (14 CFR) 25.341, Gust and turbulence loads. Section 25.341 specifies the discrete gust and continuous turbulence dynamic load conditions that apply to the airplane and engines.

This AC covers aircraft radar systems with weather detection and ground mapping, forward-looking windshear detection, forward looking turbulence detection, and atmospheric threat awareness capability. The guidance is applicable to Title 14 of the Code of Federal Regulations, parts 23, 25, 27, and 29 aircraft.

CDRs provide more flexibility for selecting an alternate departure for specific airport when traffic constraint such as thunderstorms, turbulence, and periods of excessive demand exist. Use of a CDR reduces key-entry inputs for controllers and minimizes read-back time between tower staff and pilots, which creates an abbreviated clearance.

Anticollision lights are intended to aid in collision avoidance while on the ground and in the air. Certification standards dictate field of coverage, flash characteristics, color, and light intensity.

Examples of constraints include thunderstorm activity, turbulence, and periods of excess demand. The list of flights includes aircraft that have filed flight plans, filed early intent flight plans, or operate in the constrained area based on historical flight plan data.

During summer months, these paths can be constrained by thunderstorms and turbulence. New York area departures will benefit from the additional route and increased flexibility, allowing our customers to receive more efficient air traffic services.
