Block Overflight and Landing Permits

There are two primary types of permits essential for airlines and flight operators - the Block Permit and the Adhoc/Individual Flight Permit. Understanding the distinctions between these permits is crucial for efficient flight planning and compliance. Let's delve into the block permit Vs. individual flight permit.

Block Permit

An Overview

A Block Permit is a comprehensive flight permit granted to airlines or flight operators for multiple flights within a specified timeframe. It streamlines the process by covering a series of flights based on a predefined schedule, including the origin and destination, aircraft and flight details, as well as schedule specifics. This type of permit proves especially beneficial for airlines with consistent flight routes or seasonal operations. These permits are particularly beneficial for activities such as schedule passenger flights, schedule sightseeing tours, schedule cargo operations, or seasonal events. Block permits can be obtained for overflying or/and landing, with the flight category Scheduled Commercial (Part 121).

Adhoc or Individual Flight Permit

An Overview

On the other hand, an Adhoc/Individual Flight Permit is a single-use flight permit for a specific flight. It is obtained for irregular or non-scheduled flights, diverging from the standard schedule or operating on unique routes. Each flight requires a separate application and permit, making it suitable for sporadic operations.

What to Consider When Applying for Block Permits

Airlines and flight operators seeking a Block Permit follow a structured approach to ensure compliance and efficiency. Block permits are typically sought for regular flight routes, providing a predetermined schedule, aircraft type, and specific timeframes. The conditions for applying for a block permit vary based on individual country requirements and regulations. For airlines operating seasonally, such as during peak tourism periods, seasonal block permits prove indispensable. These permits cover a set duration, often corresponding to the tourist season or might be scheduled cargo flights, streamlining the authorization process for multiple flights during this period.

Adherence to the initial schedule, encompassing origin, destination, aircraft, and flight details, is of paramount importance. Deviations from the approved schedule may require revalidation and subsequent amendments to the permit. Each country has its own set of internal regulations and guidelines provided by the Civil Aviation Authority. Adhering to these rules, especially regarding the use of block permits, is crucial to ensure compliance and avoid penalties.

In cases of any changes, such as additional aircraft registry or an extra leg to the approved schedule, it is imperative to promptly submit revisions to the block permit. Failure to do so could result in non-compliance and operational disruptions.

Lead Time

Block Vs. Individual

When it comes to lead time, block permits often require a lead time of around 15 working days, offering ample time for processing and approval. However, at VarnaJet, we leverage our strong contacts and experience to expedite this process, often securing block permits in a shorter timeframe, tailored to the specific requirements of each country. We understand that some countries may have strict procedures, but our commitment ensures we secure permits efficiently for our clients, minimizing any operational delays.

The Additional Permit Requirements

By Civil Aviation Authorities

In most countries, the additional requirements imposed by the Civil Aviation Authorities (CAAs) to obtain a block permit are often not significantly different from the requirements for an individual permit. Both necessitate thorough documentation of flight details, safety compliance, and adherence to international aviation standards. However, it's essential to note that in certain countries, the CAA may not consider flights as falling under the block permit category if they do not align with specified summer or winter season criteria. Understanding such nuances is where our expertise at VarnaJet shines, allowing us to navigate these intricacies and ensure compliance, regardless of the season or region.

Please keep in mind that most civil aviation authorities require essential aircraft documents when securing Adhoc/Individual permits, including Certificate of Airworthiness (CoA), Aircraft Registration Certificate (AR), Air Noise Certificate (ANC), and Insurance Certificate. For block permits, some civil aviation authorities may ask for Air Operator Certificate (AOC), OPS Specs, and Insurance Certificate only or in addition to the other documentations.

Letter of Authorization (LoA)

Additionally, in some countries, the Civil Aviation Authority may require a Letter of Authorization (LoA) from the flight operator or the airline. This document authorizes a local agent to obtain the permit on behalf of the flight operator or airline, streamlining the administrative process and ensuring smooth compliance with local regulations. Example of the countries with this specific requirement are:





Special Consideration - Venezuela

For operators considering flights over Venezuela, it's crucial to check for any Air Navigation debt on the operator. We recommend registering the tail numbers in the Venezuela Civil Aviation Authority system before applying for a block permit, ensuring a streamlined process and compliance with the CAA regulations.

Special Consideration - Saudi Arabia

In Saudi Arabia, for Adhoc flights, the Civil Aviation Authority imposes a permit processing fee of 100 S.R. (Saudi Rial) per overflight leg and 200 S.R. (Saudi Rial) per one landing. However, for block permits, this is not the case, and operators need to send a confirmation letter/email to the CAA, copying the service provider, confirming their awareness that all block permits are free of charge for permit processing. For block permits involving landing, we facilitate the application process through our local agent. Additionally, aircraft documentation is mandatory.

Special Consideration - UAE

In the United Arab of Emirates, for block landing permits at Dubai airport, it's important to note that slots need to be secured for all landings. Proper slot coordination is crucial to ensure smooth operations at the airport.

Special Consideration - Advanced Payment

It's noteworthy that some countries may request advanced payment of air navigation charges. This can become intricate, especially for a series of aircraft registries that have varying charges based on the maximum take-off weight (MTOW) or the distance flown. Careful financial planning and understanding of these country-specific requirements are key to a successful permit application process.
