Mongolia Overflight Permit | CAA & Ulaanbaatar FIR ZMUB Requirements

Do You Need a Mongolia Overflight Permit?

Yes. Mongolia AIP GEN 1.2 states that scheduled and non-scheduled flights in Mongolian airspace are operated in accordance with a flight permit issued by the Civil Aviation Authority of Mongolia.

Mongolia Overflight Permit Requirements

To process a Mongolia 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
• Entry and exit points with ATC route
• Purpose of flight and call sign / flight number
• Lead passenger details where applicable
• Consignee and consignor details for cargo flights

Required Documents for Mongolia Permit Processing

• Certificate of Registration (COR)
• Certificate of Airworthiness (COA)
• Valid aircraft insurance certificate
• Noise certificate if requested
• Air Operator Certificate (AOC) for commercial operators
• Flight schedule and complete routing
• Crew, passenger or cargo details where requested
• Dangerous goods declaration if applicable

Mongolia Flight Permission Lead Time

For a non-scheduled international overflight, take-off or landing request, Mongolia AIP GEN 1.2 requires submission at least 2 working days before the beginning of the operation. The AIP also provides short-notice mechanisms with additional air-navigation charges, including one calendar day and, in certain cases, at least 6 hours before operation.

Mongolia Authorization Validity and Schedule Changes

Mongolia AIP GEN 1.2 states that an international flight permission is valid for 72 hours after the beginning of flight operation. Special-flight and domestic-flight permissions have different validity periods, so the 72-hour rule should be described specifically as the international-flight permission validity.

Who Needs Mongolia Flight Clearance Support?

Mongolia flight clearance support is useful for operators crossing Ulaanbaatar FIR, operating to or from Mongolia, or planning Asia routing where multiple permits may be required.

For regional operations, operators may also review China overflight permits and Northeast 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
• Flights requiring landing, fuel, parking or ground handling in Mongolia

Mongolia FIR ZMUB Information

Mongolia airspace is divided into one main Flight Information Region: Ulaanbaatar FIR (ZMUB).

Mongolia’s main international airport serving Ulaanbaatar is supported by regional airports across the country for domestic, charter and operational movements.

For smooth operation, the requested permit route should match the operational flight plan. If ATC routing, entry point, exit point or schedule changes after approval, operators should verify whether a revision is required. For complete coordination, operators may also utilize flight support services.

Mongolia FIR Entry and Exit Points

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

Overflight Charges and Navigation Fees

Mongolia overflight charges and navigation fees may depend on aircraft type, maximum take-off weight, route, nature of operation and whether the aircraft is only overflying or also landing in Mongolia.

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

Operational Restrictions and Special Approvals

The regulatory framework covers airworthiness, flight operations, personnel licensing, air traffic services, airport operations, security, consumer protection and international civil aviation compliance.

• Civil Aviation Authority of Mongolia oversight
• Compliance with ICAO standards and recommended practices
• Airport and air traffic management requirements
• Flight plan submission and ATS coordination procedures

Mongolia AIP Flight Plan Notes

Flight plans for international and local flights should be submitted at least one hour before the start of the flight to the RMS / ARO unit at ZMUB or to the RMS unit at the departing airfield.

Special-duty, humanitarian aid, aircraft failure support, passenger recovery, spare-part delivery, navigation equipment and technical inspection flights may be treated differently from the standard flight plan timing requirement.

Flight plans and related traffic information may be provided to the Ulaanbaatar flight planning unit through the relevant AFTN, SITA, fax or operational contacts as applicable.

Additional Mongolia Flight Plan Requirements

When submitting a flight plan for Mongolia, operators should ensure the correct flight rules, type of flight, number of aircraft, equipment codes, RVSM status, navigation capability, departure aerodrome, EOBT, route, speed, altitude and date of flight are correctly filed.

About Mongolia

Mongolia is a landlocked country in north-central Asia between Russia and China. Its territory stretches across vast steppes, highlands, deserts and mountain regions, with Ulaanbaatar serving as the national capital and main aviation hub.

The country has a highly continental climate, with long cold winters and short summers. Aviation planning in Mongolia requires careful route, weather, altitude, FIR and airport coordination because of the country’s geographic scale and operational conditions.
