What is an overflight permit?

An overflight permit is an authorisation issued by a country's civil aviation authority allowing an aircraft to transit through that country's airspace without landing. It is required for virtually all international flights that cross a foreign country's airspace.

What is PPR in aviation?

PPR stands for Prior Permission Required. It is an airport-level requirement at certain airports worldwide that obligates any aircraft intending to land to obtain advance approval directly from the airport authority before arrival. It is separate from, and in addition to, any country-level landing permit requirement.

How far in advance should I request an overflight permit?

Lead times vary significantly by country, from a few hours for some European jurisdictions to 5 to 7 working days for others. ASM advises operators on country-specific timelines at the outset of every request.

What documents are typically required for a landing permit?

Typical requirements include aircraft registration certificate, AOC or Air Operator Certificate, insurance certificate, operator details and contact information, and the specific flight schedule. Requirements vary by country and operation type.

Can ASM handle urgent or same-day permit requests?

Yes, where authority timelines allow. ASM's team is available 24/7 and has established relationships that can sometimes expedite processing. ASM will always be transparent about what is feasible within a given timeframe.

What is a block permit in aviation?

A block permit covers a series of flights under a single authorisation, typically used by operators with regular routing into a specific country. It reduces per-flight administrative burden and is often more cost-efficient than individual permit applications.

Does ASM support permits for Saudi Arabia and GACA?

Yes. ASM coordinates landing permits through GACA, the General Authority of Civil Aviation, for both routine operations and the Hajj and Umrah seasons, including the specific documentation and timeline requirements that apply during peak pilgrimage periods.

Does ASM support permits for private jets and business aviation?

Yes. ASM supports permit coordination for all operation types, including scheduled airlines, cargo, charter, business aviation, private jets, VVIP movements, and special mission flights.

Who is responsible for ensuring correct permits are in place?

Ultimate regulatory responsibility rests with the operator and pilot-in-command. ASM acts as the operator's permit coordinator, managing the application, submission, and confirmation process on the operator's behalf.

Indicative Permit Lead-Time Guidance

Lead times are planning indicators only. Authority workload, holidays, major events, security requirements, aircraft nationality, flight purpose and document readiness can all change the timeline.

Region	Indicative Planning Window	What to Check
Europe	Many clearances may move within 24–48 hours, but landing and airport-level requirements vary.	Slots, curfews, PPR, parking, event restrictions and airport operating hours.
Middle East	Several jurisdictions require 24–72 hours, with longer planning needed for sensitive seasons or special movements.	Authority documentation, restricted airspace, diplomatic activity and religious travel peaks.
Asia-Pacific	Some jurisdictions require 48–96 hours, while others may need several working days.	Country-specific forms, routing, permit validity windows and aircraft nationality.
Africa	Lead times vary widely by country, documentation route and local processing method.	Public holidays, local follow-up needs, payment processes and handler coordination.
Americas	Many routes are straightforward, but landing, border, APIS or airport requirements may still apply.	Customs, airport hours, notice periods and special mission requirements.

These ranges are general planning references and are not guaranteed processing times. Country, airport, authority, aircraft and operation-specific requirements must be confirmed for each request.

From Route Request to Clearance Handover

ASM keeps permit coordination structured so route details, documents, authority requirements and operational updates move through the same review path.

01

Review the Route

ASM reviews the schedule, aircraft, operator details, route, FIRs and purpose of flight.

02

Check Requirements

The team checks country, airport, PPR, seasonal and documentation requirements.

03

Coordinate Submission and Follow-Up

Requests are coordinated through the relevant Civil Aviation Authority, airport, approved representative or other authorised local channel.

04

Handover and Updates

Clearance status is shared and aligned with planning, fuel, handling or crew logistics where needed.

ASM’s permit coordination process moves from request review to authority follow-up and operational handover.

Details to Share for a Permit Request

Complete information at enquiry stage helps reduce back-and-forth and gives the team a clearer basis for authority review.

✓ Departure, destination, alternates, FIRs and proposed schedule

✓ Aircraft type, registration, nationality and MTOW

✓ Operator details, AOC information where applicable and billing contact

✓ Flight purpose: commercial, cargo, charter, private, medevac, ferry or special mission

✓ Crew, passenger, cargo and supporting certificate details where required

Permit Coordination and Operator Responsibility

Permit requirements can change by country, airport, aircraft, operator and flight purpose. ASM coordinates the documentation, submission and follow-up process, but the aircraft operator remains responsible for ensuring the operation complies with applicable regulations.

Urgent requests can be reviewed, but final feasibility depends on authority processing times, complete documents and airport or airspace restrictions.
