    • Annex 14 Aerodromes Volume 1 Aerodrome Design and Operations By:- Cheng Ling Perng
    • The Objectives
      • Understanding the philosophy of ICAO’s Annex 14 SARP for Aerodromes
      • Identify, explain and discuss the more important Standard And Recommended Practices (SARPs) of Annex 14
    • Methodology
      • Classroom manual text review (referring to Annex 14 text & review accordingly)
      • Study of texts, tables, figures & charts
      • Discussions on important topics and how to resolve the issues
      • Technical visit to an aerodrome (if necessary)
    • Development of SARPs
      • ICAO adopted Aerodrome SARPs in 1951 & designated it as Annex 14
      • Many amendments since 1951
      • 1990, Annex 14 split into 2 volumes
        • Vol. 1 - Aerodrome Design & Operations
        • Vol. 2 - Heliports
      • Signatories agree to abide by or to exceed the standards
      • If signatories choose to differ, they must file a difference with ICAO
    • Annex 14 Amending Process
      • A country submits an issue to ICAO
      • If pertinent, ICAO forms a Project Team
      • Research, risk analysis & impact assessments are done over a few years
      • Brought before the aerodrome ICAO main meeting
      • Draft and consultation
      • Final amendments
        • Ex. International Runway Friction Index (IRFI)

    • Standard
      • Any specification, the uniform application of which is recognized as necessary for the safety or regularity of international air navigation and to which Contracting States will conform in accordance with the Convention
    • Recommended Practice
      • Any specification, the uniform application of which is recognized as desirable in the interest of safety, regularity or efficiency of international air navigational, and to which Contracting states will endeavour to conform in accordance to the Convention
    • SARPs
      • Standards are identified by the verb < shall > and are mandatory
      • Recommended practices are identified by the verb < should > and are only recommendations
    • Critical Aircraft
      • The aeroplane identified from among the aeroplanes the aerodrome is intended to serve has having the most demanding operational requirements
    • Aeroplane reference Field Length
      • The minimum field length required for take-off at maximum certificated take-off mass, sea level, standard atmospheric conditions, still air an zero runway slope, as shown in the appropriate aeroplane field manual
    • The First Premise: The Aerodrome Reference Code
      • The aerodromes are coded according to the physical requirements of the critical aircraft
      • The aerodrome facilities (or part of) must meet physical requirements of the critical aircraft
    • Motivation
      • Understanding the rationale applied in the development of Annex 14 will help the aerodrome inspector/operator to be more consistent in their interpretation and application of SARPs
      • It will be helpful for them to have a thorough knowledge of SARPs that are more difficult to understand
    • Methodology

    • Part I Outline
      • Development of SARPs
      • Amending Process
      • Annex 14 Table of Contents

    • The Aerodrome Coding Concept
      • Based on two premises
        • Aerodrome reference code
        • Type of approach
      • Example: 3C NP
      • Designed as a planning tool
      • Applied in reverse when aerodrome built
    • Aerodrome Reference Code Table 1-1. Aerodrome reference code (se 1.3.2 to 1.3.4) a. Distance between the outside edges of the main gear wheels. Up to but not including 4.5 m 4.5 m up to not including 6 m 6 m up to not including 9 m 9 m up to not including 14 m 9 m up to not including 14 m 14 m up to not Including 16 m Up to but not including 15 m 15 m up to but not including 24 m 24 m up to but not Including 36 m 36 m up to but not including 52 m 52 m up to but not including 65 m 65 m up to but not Including 80 m A B C D E F Less than 800 m 800 m up to but not including 1 200 m 1 200 m up to but not including 1 800 m 1 800 m and over 1 2 3 4 Outer main gear wheel span (5) Wing span (4) Code letter (3) Aeroplane reference field length (2) Code number (1) Code element 2 Code element 1
    • Non-Instrument Runway (NI)
      • A runway intended for the operation of aircraft using visual approach procedures
    • Non-Precision Runway (NP)
      • An instrument runway served by visual aids and a non-visual aid providing at least lateral guidance adequate for a straight-in approach
    • Precision Runway (P) Category I
      • An instrument runway served by ILS and/or MLS and visual aids intended for operations with a decision height not lower than 60m (200 ft) and either a visibility not less than 800 m or a runway visual range (RVR) not less than 550 m
    • Precision Runway (P) Category I
      • Lateral and vertical guidance
      • Down to 60 m (DH)
      • Operating visibility not less than 880 m or RVR 550 m
      • Most common of P runways
    • Precision Runway (P) Cat II - III
      • Same as Cat I except Cat II has DH down to 30 m (100 ft) with visibility not less than RVR 350 m
      • Same as Cat I except Cat III has DH and visibility from an RVR of 200 m (600 ft) down to no visual range limitations
    • The Second Premise: The Type of Approach
      • The SARPs translate the combination of the Aerodrome Reference Code and the type of approach procedure available for the runway (Ex. 3C NP) into specific aerodrome physical requirements
      • The safety margin is increased as the approach minima is lowered
    • Review
      • What differentiates a non-instrument runway from a non-precision runway?
      • What two factors establish the rationale behind the SARPs?
      • Aerodrome reference codes are based on two elements. What are they?
      • How do SARPs change with lower approach minima?
      • Physical Characteristics and Obstacle Limitation Surfaces
      • (OLS)

    • Runway Characteristics
      • Primary runway should be adequate to meet operational requirements of critical aircraft
      • Length of runway corrected for elevation, temperature, slope, humidity and surface
      • Length or runway need not be for maximum mass operations of critical aircraft
      • Similar rationale for secondary runway
    • Runway Strip
      • Defined in Annex 14
      • A defined area including the runway and stopway, if provided, intended:
        • To reduce the risk of damage to aircraft running off a runway ; and
        • To protect aircraft flying over it during take-off or landing operations
    • Graded Area
      • Not defined in Annex 14
      • Included in the strip
      • Intended to serve in the event of an aeroplane running off the runway
      • Obstacle free and free of ditches, holes
      • Supportive of vehicles and aircraft
    • Obstacle Limitation Surfaces (OLS) Purpose
      • To define the airspace around aerodromes to be maintained free of obstacles so as to permit safe aerodrome operations and to prevent the growth of obstacles around aerodromes
    • Obstacles Limitation Surfaces (OLS) Requirements

    • The Strip & the Inner Edge
      • Strip provides protection for a/c on the ground & in flight
      • Usually slope of OLS starts at outer edge of strip
      • In a displaced threshold, the inner edge of OLS is at the point of displacement
      • The inner edge is the point at which the approach surface commences
      • So, strip end & inner edge are not always co-located
    • Questions
      • If a runway is 1000 m long, how long is the strip?
      • Runway 06/24 is 2500 m long. Threshold of 06 is displaces 300 m and the threshold of runway 24 is displaced 250 m. How long is the strip?
