120-112 AFS-200 Use of Liquid Water Equivalent System to Determine Holdover Times or Check Times for Anti-Icing Fluids

This advisory circular (AC) provides guidance for the Federal Aviation Administration’s (FAA) standard for a Liquid Water Equivalent System (LWES). This AC applies to anyone proposing to design, procure, construct, install, activate, or maintain an LWES. An LWES is an automated weather measurement system that determines the Liquid Water Equivalent (LWE) rate in conditions of frozen or freezing precipitation. The LWE rate is used by the system with the appropriate endurance time (ET) regression equations and regression coefficients specified in an FAA-approved current database at http://66.46.192.186/RegressionInformation.html to determine the holdover time (HOT) or check time (CT) for an aircraft’s applied anti-icing fluid (Society of Automotive Engineer (SAE) Types I, II, III, and IV). Thus, the LWES incorporates a Holdover Time Determination System (HOTDS) or Check Time Determination System (CTDS). The HOT is used to determine how long a fluid would provide protection assuming that the current conditions do not change. The CT is used to determine the fluid’s current protection capability, while incorporating varying weather conditions.

135-14B AFS-200 Helicopter Air Ambulance Operations

Helicopters provide a means of transporting people in urgent need of medical assistance. These operations are unique due to the urgent nature of the flight. Each year thousands of patients are transported by helicopter while being attended by medical personnel trained to respond to their needs. Helicopter air ambulances (HAA) are equipped with medical monitoring and support systems to ensure proper care en route.

The HAA industry continues to expand. In response to the dynamic growth of this industry, the Federal Aviation Administration (FAA) has issued this advisory circular (AC) to provide information and guidelines to assist existing HAA operators, other Title 14 of the Code of Federal Regulations (14 CFR) part 135 operators considering becoming an HAA operator and those considering new-startup HAA operations. To address an increase in fatal HAA accidents, the FAA has implemented new operational procedures and additional equipment requirements for HAA operations. The FAA, HAA operators and medical community all play vital roles in applying these changes to ensure safety. Implementing a safety culture will benefit all aspects of HAA operations.

Part 135 subpart L addresses safety improvements for commercial helicopter operations through requirements for equipment, pilot testing, alternate airports and increased weather minimums for all General Aviation (GA) helicopter operations. Many of these requirements also address National Transportation Safety Board (NTSB) safety recommendations directed at improving HAA safety.

120-92B AFS-900 Safety Management Systems for Aviation Service Providers

This advisory circular (AC) provides information for Title 14 of the Code of Federal Regulations (14 CFR) part 121 air carriers that are required to implement Safety Management Systems (SMS) based on 14 CFR part 5. Specifically, this document provides a description of regulatory requirements, guidance, and methods of developing and implementing an SMS. This AC may also be used by other aviation service providers interested in voluntarily developing an SMS based on the requirements in part 5.

An SMS is an organization-wide comprehensive and preventive approach to managing safety. An SMS includes a safety policy, formal methods for identifying hazards and mitigating risk, and promotion of a positive safety culture. An SMS also provides assurance of the overall safety performance of your organization. An SMS is intended to be designed and developed by your own people and should be integrated into your existing operations and business decisionmaking processes. The SMS will assist your organization’s leadership, management teams, and employees in making effective and informed safety decisions.

Part 5 specifies a basic set of processes integral to an effective SMS but does not specify particular methods for implementing these processes. In other words, the regulation defines "what" must be accomplished, not "how" it must be accomplished. This AC provides additional guidance on how the SMS may be developed to achieve the safety performance objectives outlined by your organization. As is demonstrated by this AC, there is no one-size-fits-all method for complying with the requirements of part 5. This design is intentional, in that the Federal Aviation Administration (FAA) expects each air carrier to develop an SMS that works for its unique operation. Thus, this AC provides guidance regarding designing and implementing acceptable methods of compliance with the requirements of part 5. These methods, however, are not the only means of compliance.
