Understanding ICAO Doc 8168, Volume III: Aircraft Operating Procedures ICAO Document 8168, widely known as
(Procedures for Air Navigation Services – Aircraft Operations), is the foundational global standard for flight procedures. While Volumes I and II focus on flight maneuvers and procedure construction respectively, Volume III specifically addresses Aircraft Operating Procedures to guide flight crews and operations personnel Foundation for Aviation Competence (FFAC) Core Purpose and Scope
Volume III was established to consolidate operational procedures that were previously part of Volume I, creating a dedicated guide for ensuring the highest levels of safety during flight. It describes recommended practices that fall outside the formal Standards and Recommended Practices (SARPs) but still require international uniformity for safe operations. ICAO Store Key Content and Chapters
This volume provides technical guidance on standardized air navigation and operating techniques, including: Altimeter Setting Procedures:
Standards for setting pressure values to ensure vertical separation and terrain clearance. Holding Patterns:
Standardized entries and timing for aircraft instructed to remain in a defined area. Visual Maneuvering (Circling): icao doc 8168 volume 3
Criteria for safe low-level maneuvering near an airport when visual contact is maintained. Instrument Approach Procedures:
Operational guidance for using various instrument systems for landing. Transition Altitude:
Criteria and requirements for establishing the altitude at or below which the vertical position of an aircraft is controlled by reference to altitudes. International Civil Aviation Organization Implementation and Status
Unlike Annexes to the Chicago Convention, PANS do not carry the same legal weight as SARPs. Instead: peter2000.co.uk State Responsibility: It is the responsibility of individual Contracting States
to implement and enforce these procedures within their own regulations. Operator Responsibility: Understanding ICAO Doc 8168, Volume III: Aircraft Operating
While Doc 8168 assumes normal operations, aircraft operators must provide their own contingency procedures for abnormal or emergency situations. GlobalSpec Regulatory Context
The first edition of Volume III was approved in 2018 and became applicable globally on November 8, 2018
. It is a critical resource for flight training organizations and commercial operators to ensure their flight manuals align with international safety expectations. Foundation for Aviation Competence (FFAC) requirements or altimeter setting Aircraft Operations
To understand this volume, you must grasp a few key concepts:
Volume III covers operational aspects distinct from the design criteria in Volumes I and II: GNSS/RNAV approaches for helicopters
| Feature | Volumes I & II | Volume III | |---------|----------------|-------------| | Focus | Design of instrument flight procedures (IFP) | Operation of aircraft using those procedures | | Audience | Procedure designers, surveyors, ATS authorities | Flight crews, operators, ATC | | Content | Obstacle clearance margins, turn radii, altitude calculation | Pilot actions, missed approach execution, stabilization criteria |
While Volume I defines General criteria and Volume II defines Visual and Instrumental flight procedures, Volume III is titled: "The Training of Flight Procedures Designers and the Flight Validation of Procedures."
Yes, you read that correctly. The third volume isn't for pilots—it is for the people who build the RNAV approaches and the pilots who test them before you get to use them.
Think of it this way:
Aircraft manufacturers and airlines use ICAO standards as the foundation for their Standard Operating Procedures (SOPs). When you read a Boeing or Airbus flight crew training manual, much of the underlying logic traces back to the criteria set forth in ICAO Doc 8168.
