Sri Lanka Overflight Permit | CAASL & Colombo FIR Requirements

Do You Need a Sri Lanka Overflight Permit?

Yes. CAASL publishes a specific process for issuance of overflying permission to fly over the Colombo FIR for non-scheduled flights. Applications are to be submitted in the format specified in Sri Lanka AIP GEN 1.2.

Sri Lanka Overflight Permit Requirements

To process a Sri Lanka overflight permit, operators should normally provide the following details:

• Aircraft registration and aircraft type
• Operator name and full contact details
• Complete flight schedule with UTC date and time
• Departure airport and destination airport
• Full route including Sri Lanka FIR entry and exit points
• ATC route and call sign / flight number
• Purpose of flight and type of operation
• Lead passenger details where applicable
• Consignee and consignor details for cargo flights where required

Required Documents for Sri Lanka Permit Processing

• Certificate of Registration (COR)
• Certificate of Airworthiness (COA)
• Valid aircraft insurance certificate (COI)
• Noise certificate (CON)
• Air Operator Certificate (AOC) for commercial operators
• Crew and passenger details when required
• Dangerous goods declaration if applicable

Sri Lanka Flight Permission Lead Time

CAASL currently publishes a required processing time of 3 working days for overflying permission to fly over the Colombo FIR and also 3 working days for non-scheduled landing permission. Ambulance, search-and-rescue and relief flights are handled at the earliest under the applicable AIP procedure.

Sri Lanka Authorization Validity and Schedule Changes

Do not use a generic +48-hour validity window unless it appears in the actual approval. Sri Lanka permissions are issued against the approved aircraft, route, schedule and purpose, and material changes should be coordinated before departure.

Who Needs Sri Lanka Flight Clearance Support?

Sri Lanka flight clearance support is useful for operators crossing Colombo FIR, planning landing at Sri Lankan airports, or operating Indian Ocean and South Asia routes where several permits are required within a short timeframe.

For regional operations, operators may also review India overflight permits and neighboring South Asia routing requirements.

• Private jet and business aviation operators
• Non-scheduled charter flight operators
• Cargo and air freight operators
• Ambulance, medevac and humanitarian flights
• Ferry, delivery and aircraft positioning flights
• Scheduled and non-scheduled airline block permit operations
• Flights requiring landing, fuel, parking or ground handling in Sri Lanka

Sri Lanka FIR VCCF Information

Sri Lanka airspace is commonly planned through Colombo FIR (VCCF). Operators should verify FIR boundary estimates, ATS routing, entry and exit points and AFTN addressing where applicable.

Major gateways include Bandaranaike International Airport (VCBI/CMB), Mattala Rajapaksa International Airport (VCRI/HRI) and other domestic / regional airports.

For smooth operations, the requested permit route should match the operational flight plan. If ATC routing, entry point, exit point, level planning or schedule changes after approval, the operator should check whether a revision is required before filing or operating the flight. For complete coordination, operators may also utilize flight support services for route validation and permit follow-up.

Sri Lanka FIR Entry and Exit Points

The following entry and exit points are commonly used for route planning through Colombo FIR. Operators should verify routing against the latest approved ATS route structure before filing the flight plan.

Sri Lanka Flight Plan and AFTN Considerations

Flight plans should be submitted for IFR flights, international flights and applicable VFR flights. Operators should prepare the ICAO flight plan with complete and correct route, schedule, aircraft identification and operational details.

Non-scheduled and private flight operations into or across Sri Lanka territory should include the Sri Lanka DGCA / CAASL flight clearance number or re-clearance number in Item 18 of the filed flight plan when applicable.

Flight Plan Changes, Delay and Cancellation

All changes to a submitted IFR flight plan or controlled VFR flight plan should be reported as soon as possible to the appropriate ATS unit. If departure is delayed by 30 minutes or more, the flight plan should be amended or a new flight plan submitted after cancellation of the old one.

Whenever a flight for which a flight plan has been submitted is cancelled, the appropriate ATS unit should be informed immediately. Arrival reports may also be required after landing when the arrival has not been acknowledged by the local ATS unit.

Overflight Charges and Navigation Fees

Sri Lanka overflight charges and related navigation fees may depend on the type of aircraft operation, route, aircraft weight category, authority requirements and whether the flight is only crossing Sri Lankan airspace or also landing in Sri Lanka.

Where landing is involved, operators should also consider airport charges, parking, ground handling, fuel uplift, supervision, passenger handling, cargo handling and any additional service charges requested for the operation.

Operational Restrictions and Special Approvals

Certain flight categories may require additional review or longer coordination time. Operators should provide complete information early when the flight involves special cargo, state-related movement, dangerous goods, ambulance operation or unusual routing.

• Military, diplomatic or state flights
• Dangerous goods or special cargo flights
• Ambulance, medevac and humanitarian missions
• Survey, inspection or scientific flights
• Flights with restricted cargo or unusual routing
• Flights requiring landing permit, passenger handling or cargo handling
