All you need to know about Permit Revision

by Admin on June 1, 2022

Overflight and landing permits are one of the most challenging and important requirements for any airline and flight operator, where there are many variable factors and documentations to consider when applying for flight permits case of schedule change can create permit revisions for all subsequent countries for that flight or some of them as per the permits revision rules of each CAA (CIVIL AVIATION AUTHORITY). Unfortunately, revisions can’t always be avoided and be mindful that you’ll only be permitted two revisions.


What’s the difference between CAA and FAA?

CAA; civil aviation authority is a national or supranational statutory authority that oversees the regulation of civil aviation, including the maintenance of an aircraft register.

While FAA; Federal Aviation Administration; the division of the Department of Transportation that inspects and rates civilian aircraft and pilots, enforces the rules of air safety, and installs and maintains air-navigation and traffic-control facilities.


What is flight permit?

Flight permits are permissions required by an aircraft to overfly, land or make a technical stop in any country’s airspace. And these permits should meet the conditions of International Civil Aviation Organisation (ICAO)

Each CAA in every single country has its own regulations regarding the issuance of flight permits as there is generally a payment involved. The charges normally payable would be the Route Navigation Facility Charges or RNFC for overflights and also landing and parking charges in case of aircraft making halts.

The procedure for issuance of these permits varies from country to country, each country has its civil aviation authority website where you can find all details and regulations related to permits over this country.

Confirmation and issuing an overflight permit means that there is no political or security objection to your airline, aircraft, or country of origin/ destination, and it’s safe to fly over.


Flight permits types:

1- Overflight Permits

2- Landing Permits

3- Special Flight Permits



What is a special flight permit?

A special flight permit is issued for an aircraft that currently may not meet applicable airworthiness requirements, but is capable of safe flight.


Purposes of Issuing a Special Flight Permit:

  • Flying to an airport where aircraft maintenance is available.
  • Flying with extra MTOW.
  • Ferry permits, which is the delivery flight of a recently bought aircraft to its owner’s destination before completing all the necessary documents and issuing an airworthiness certificate for the aircraft.
  • Aircraft testing after production.
  • Evacuating the aircraft from dangerous areas (hurricanes, tornados, wildfires).

Difference between Overflight permit and Landing permit:

Overflight permits: is an authorization from Civil Aviation Authorities (CAAs) to overfly that country’s airspace.

Landing Permit: is an authorization to land at a given airport, it confirms that there are no noise or safety objections to your type of aircraft.

For sure there are some Countries Where Flight Permits Are Challenging to get as The issuance of these flight permits have different lead times, different regulations according to the traffic the airports receive and the type of flight the operator is planning.

Some CAAs aren’t reachable or contact it directly to get OVF permits, in this case the help of and agent or a third party is necessary and there will be extra charge for this agent due this service.


List of Some Regions which require/don’t require Flight permit:

  • South America: In general, both overflight and landing permits are required.
  • Europe: Non-scheduled flights in general do not require Overflight Permits for EU Countries. Other countries – check. Note that some Airports in Europe may be both PPR (Prior Permission Required) and require Airport Slots.

  • Landing permits, to take-off/land on any airport worldwide in addition to arrange ground handling services and airport slots.
  • Certificate of registration,
  • Noise certificate,
  • Insurance Certificate
  • Airworthiness review certificate
  • Diplomatic permits for the operation of diplomatic and government flights.


Charges of flight permits, validity and revision

Overflight permits charges are different from country to the other, where Civil Aviation Authorities (CAAs) charge a flat fee for overflight permits, while other CAAs charge by the length of time in the airspace, or even based on the weight of the aircraft.

Permit revision is required when there is a change in departure point, destination, registration number and/or call sign, crew and passenger information, routing, entry and exit FIRs, or add/remove legs.  It’s important to know all procedures for permits revision before any flight as permit validity is related to CAA’s regulations, some may charge for short-notice, others give validity +/- 72 hours, while others only allow the approved flight plan time as given. For example; Russian permits if you arrive at the Flight Information Region (FIR) even 5 minutes early, a permit revision is needed.

Last-minute route changes can cause delays of up to two days in some regions. If too many changes are requested, CAAs may deny revisions. For example, rebuilding a route from Hong Kong to Europe may require several new permits and a couple of days lead time. It’s easier to revise a permit based on the same entry and exit points than to apply for a new permit. So try to keep your schedule as firm as possible and avoid last-minute changes, especially in China, India, and Russia.
