Which FLIP document provides information on two-way radio failure?

The correct choice is the Flight Information Handbook. This document is designed to provide pilots and aircrew with essential information pertaining to flight operations, including procedures for dealing with various system failures. The two-way radio failure scenario is particularly critical, as effective communication is necessary for safe flight operations.

The Flight Information Handbook includes guidelines on how to manage situations when two-way radio communications are lost, outlining necessary procedures to maintain safety and navigate accordingly. Understanding these procedures helps pilots to ensure safety during instances of communication failure.

Other documents like the Flight Safety Manual focus on broader safety policies and protocols rather than specific operational details regarding radio failures. The FLIP Enroute IFR Supplement primarily lists enroute navigation information and does not address communication failures directly. Aeronautical Charts serve as navigation tools and do not contain detailed procedures regarding equipment failures. Thus, the Flight Information Handbook is the most appropriate reference for information on two-way radio failure.
