    Study Notes

    Aerodrome and Runway Elevations

    • Aerodrome elevation and geoid undulation must be measured to an accuracy of one-half meter or one foot and reported to AIS-CAAP.
    • For non-precision approaches, the runway end elevations and significant high/low points must also be reported with the same accuracy.
    • For precision instrument runways, key elevations including threshold and highest touchdown zone points require the same accuracy for reporting.

    Declared Distances

    • Declared distances for runway intersections start at a perpendicular line from the farther edge of the taxiway from the take-off direction.
    • If take-offs can occur in both directions, separate declared distances must be defined for each direction from respective taxiway edges.
    • Example format for intersection departure: "RWY 16 – TKOF from TWY E: RWY remaining 2345 (7694), reduce all DECL DIST by 1312 (4305)."

    Aerodrome Obstruction Charts – Type A

    • Type A Charts must indicate the currency of the information, including date of preparation or edition/issue number.

    Obstructions and Take-off Gradients

    • If fences or levee banks are too close to the runway affecting take-off gradients, the next obstacle in the take-off area may be considered for gradient calculations.

    Factors for Site Selection for Major Airports

    • Regional Plan: Site must integrate into the national airport network.
    • Airport Use: Selection depends on whether the airport is for civilian or military.
    • Proximity to Airports: Selected sites should be distanced from existing airports to prevent interference.
    • Ground Accessibility: Sites should be easily accessible for users, critical for short-haul operations.
    • Visibility: Airports must be free from visibility-reducing conditions such as fog or smoke.
    • Noise Nuisance: Sites should minimize noise impact on surrounding areas, considering aircraft climb-out paths.

    Aeronautical Information

    • Aeronautical Information Service (AIS) collects and publishes aeronautical data, important for aviation stakeholders.
    • Key publications include:
      • Aeronautical Information Publication (AIP): Essential aeronautical information.
      • AIP Amendment: Permanent updates to AIP data.
      • AIP Supplement: Temporary updates, published on special pages.
      • NOTAM: Notices regarding changes or hazards important for flight operations.

    Aerodrome Information Elements

    • Location Information: Includes name, WAC number, coordinates, magnetic variation, UTC time, and local time differences.
    • Ground Services: Includes fuel suppliers' contact details, weather information, and available services for pilots.
    • Special Procedures: Unique procedures specific to an aerodrome that pilots need to be aware of.

    Runway Surface Types

    • Runway surfaces are classified as:
      • Bitumen seal
      • Asphalt
      • Concrete
      • Gravel
      • Grass
      • Natural surface

    Tire Pressure Categories

    • Unlimited: No limit
    • High: 1.75 MPa
    • Medium: 1.25 MPa
    • Low: 0.50 MPa

    Pavement Strength Categories

    • High Strength: K value ≥ 150 MN/m³; CBR ≥ 15 for rigid pavements.
    • Medium Strength: K value between 60-120 MN/m³; CBR 10-13 for flexible pavements.
    • Low Strength: K value < 80 MN/m³; Technical evaluations required for bearing strength assessments.

    Technical Evaluation

    • Characterization of pavement strength provides crucial data for aircraft operations and maintenance.

    Example Evaluation

    • A rigid pavement on medium strength subgrade with a technical evaluation PCN 80 and no tire pressure limitations leads to standardized reporting requirements for operations.
