ICAO Doc 8168, titled Procedures for Air Navigation Services — Aircraft Operations (PANS-OPS), includes Volume III: Aircraft Operating Procedures. This volume is specifically designed to provide operational guidance to flight crew and flight operations personnel to ensure high safety standards during all phases of flight. Core Purpose and Scope

Call to Action: Check your company’s operations manual. Does it reference ICAO 8168 Vol III for missed approach climb gradients? If not, ask your Chief Pilot. You might be the one who starts a safety conversation.

Criteria for safe low-level maneuvering near an airport when visual contact is maintained. Instrument Approach Procedures:

Part III – Reversal Procedures

Before GPS and RNAV, reversal procedures were the only way to turn an aircraft 180 degrees after passing a fix to intercept an inbound track. Volume 3 codifies two types:

Flight Procedures: Standardized maneuvers for various phases of flight, including takeoff, approach, and landing.

  • Volume I: Flight Procedures (for pilots).
  • Volume II: Criteria for the Construction of Visual and Instrument Flight Procedures (for procedure designers).
  • Volume III: (The subject of our deep dive) – The Manual for the Establishment of Holding, Reversal, and Racetrack Procedures.

2. Core Sub-features

  • Version tracking (current: Amendment 9, with future update alerts)
  • Cross-references to Volumes I & II where applicable

Primary Audience: Highly recommended for pilots and flight operations teams as a guide for safe and standardized air navigation. Content and Key Sections

  • Operational Approval: A specific authorization included in the Air Operator Certificate (AOC) or Operations Specifications.
  • Validation Flight: A flight conducted specifically to prove to the authority that the crew and aircraft can perform the new operation.
  • Continuing Airworthiness: Ensuring the aircraft remains fit to fly the operation (e.g., keeping GPS receivers calibrated).
  • Alerting Service: Notifying crews when the navigation equipment is not meeting performance standards.
