Oceanic Operations Exam

The Oceanic Operations Exam tests your knowledge of procedures, regulations, and best practices for flights over oceanic airspace, where radar and communication coverage is limited. It ensures pilots are equipped to handle navigation, communication, and contingency scenarios in remote and non-radar environments.

Key Topics to Study

1. Airspace Structure and Navigation

Oceanic airspace classifications (e.g., NAT HLA, PACOTS, WATRS).
Organized Track Systems (e.g., NAT Tracks, PACOTS).
Lateral and longitudinal separation minima.
Required Navigation Performance (RNP) and Performance-Based Navigation (PBN).

2. Flight Planning for Oceanic Operations

How to plan for crossing track systems.
Filing an ICAO flight plan for oceanic airspace.
Alternates, ETOPS considerations, and diversion planning.
Calculation of Critical Point (CP) and Equal Time Point (ETP).

3. Communication Procedures

HF radio communications and SELCAL operation.
CPDLC (Controller Pilot Data Link Communication) and ADS-C (Automatic Dependent Surveillance-Contract).
Position reporting formats (e.g., using latitude/longitude or waypoints).
Emergency and loss-of-communication protocols.

4. Navigation Systems

Use of GNSS, INS/IRS, and FMC for oceanic navigation.
Cross-checking navigational accuracy and monitoring RNP compliance.
Importance of waypoint plotting and cross-verification.

5. Reduced Vertical Separation Minimum (RVSM)

Criteria for RVSM approval (aircraft and crew requirements).
Level allocations and transition between metric and imperial altitudes.
Procedures in case of turbulence or equipment failure in RVSM airspace.

6. Weather and Environmental Considerations

Volcanic ash avoidance and tropical storm procedures.
Monitoring and planning for jet streams and turbulence.
Polar navigation considerations (e.g., magnetic variation and cold weather ops).

7. Contingency Procedures

Procedures for weather deviations and turbulence avoidance.
Engine-out scenarios and fuel imbalance over the ocean.
Loss of navigation capability or aircraft system failures.

8. Regulatory Framework

ICAO Annex 2, 6, and 11 related to oceanic operations.
Regional differences in airspace requirements (e.g., NAT, Pacific, Indian Ocean).
