International borders are shared with Thailand and the Lao People’s Democratic Republic on the West and the North, and the Social Republic of Viet Nam on the East and the Southeast. The country is bounded on the Southeast by the Gulf of Thailand. In comparison with neighbors, Cambodia is a geographical contact country administratively composed of 20 provinces, three of which have relatively short maritime boundaries, 2 municipalities, 172 districts, and 1,547 communes.

Cambodia Overflight Permits Procedures

The Given Below Information Is Extracted from the Cambodia AIP

Procedure Of Submission a Flight Plan

A flight plan shall be submitted in accordance with ICAO Annex 2, 3.3.1, prior to operating any IFR or VFR flight.

Time Of Submission

Except for repetitive flight plans, a flight plan shall be submitted at lest 30 minutes prior to departure, taking into account the requirements of ATS units in the airspace along the route to be flown for timely information.

Place Of Submission

I- Flight plans shall be submitted to the AIS unit at Phnom Penh International Airport, or the aerodrome control unit at Siem Reap International Airport.
II- Flight plans for departures from other points within the Kingdom of Cambodia shall be telephoned or faxed to the AIS unit at Phnom Penh Airport at 855-23-890- 262.

VFR Flight Plan For Alerting Service Only

An alerting service is, in principle, provided to flights for which a flight plan has been submitted.

Contents And Form Of A Flight Plan

I-ICAO flight plan forms are available at AIS units and airport offices. The instructions for completing these forms shall be followed.
II-Flight plans concerning IFR flights along ATS routes need not include FIR boundary crossing estimates. Inclusion of FIR-boundary estimates is, however, required for off-route IFR flights and international VFR flights.
III-When a flight plan is submitted by telephone, teletype or fax the sequence of items in the flight plan form shall be strictly followed.

Changes To The Submitted Flight Plan

All changes to a flight plan submitted for an IFR flight or an international VFR flight shall be reported as soon as possible to the appropriate ATS unit. In the event of a delay of 30 minutes or more of the departure of a flight for which a flight plan has been submitted, the flight plan shall be amended or a new flight plan shall be submitted after the old plan has been canceled.

Note 1-If a delay in the departure of a controlled flight is not properly reported, the relevant flight plan data may no longer be readily available to the appropriate ATS unit when a clearance is ultimately requested, which will result in an extra delay for the flight.

Note 2-If a delay in departure or cancellation of an uncontrolled VFR flight is not properly reported, alerting or search and rescue action may be unnecessarily initiated when the flight fails to arrive at the destination aerodrome within 30 minutes after its current ETA.

Whenever a flight for which a flight plan has been submitted is canceled, the appropriate ATS unit shall be informed immediately.

Arrival Report (Closing A Flight Plan)

A report of arrival shall be made at the earliest possible moment after landing to the airport office of the arrival aerodrome except when the arrival has been acknowledge by the local ATS unit. In the case of a diversionary landing, the local ATS unit shall be specifically informed accordingly. In the absence of an ATS unit at the point of landing, the pilot is responsible for passing the arrival report to the destination aerodrome.

Arrival reports shall contain the following information:

• Aircraft Identification
• Departure Aerodrome
• Destination Aerodrome
• Arrival Aerodrome
• Time Of Arrival

In the case of diversion, insert the "arrival aerodrome" between "destination aerodrome" and "time of arrival".

When the height of the transition altitude is lower than 10 000 ft (3 050 m) AMSL, FL 100 should be used in lieu of 10 000 ft.

I - Lower flight visibility to 1500 M may be permitted for flights operating:
• At speeds that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision.
• In circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low traffic volume and for aerial work at low levels
II - Helicopters may be permitted to operate in less than 1500 m flight visibility if maneuvered at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision.

When the height of the transition altitude is lower than 10 000 ft (3 050 m) AMSL, FL 100 should be used in lieu of 10 000 ft.

Unlawful Interference


The following procedures are intended for use by aircraft when unlawful interference occurs and the aircraft is unable to notify an ATS unit of this fact.


Unless considerations aboard the aircraft dictate otherwise, the pilot-in-command should attempt to continue flying on the assigned track and at the assigned cruising level at least until notification to an ATS unit is possible or the aircraft is within radar coverage.

When an aircraft subjected to an act of unlawful interference must depart from its assigned track or its assigned cruising level without being able to make radiotelephony contact with ATS, the pilot-in-command should, whenever possible:

1- Attempt to broadcast warnings on the VHF emergency frequency and other appropriate frequencies, unless considerations aboard the aircraft dictate otherwise. Other equipment such as onboard transponders, data links, etc. should also be used when it is advantageous to do so and circumstances permit.

2- Proceed in accordance with applicable special procedures for in-flight contingencies, where such procedures have been established and promulgated in Doc. 7030, Regional Supplementary Procedures.

3- If no applicable regional procedures have been established, proceed at a level which differs from the cruising levels normally used for IFR flight in the area by 1 000 ft (300m) if above FL 290 or by 500 ft (150m) if below FL 290.
