What PPR means
PPR stands for Prior Permission Required. It is a condition attached to certain airports: an aircraft may not land until the aerodrome operator has granted specific permission for that flight, on that day, with that aircraft.
It exists so airports can manage infrastructure and capacity — stand availability, ground handling, fire category, opening hours — and, increasingly, so they can screen flights against sanctions before an aircraft is in the air. An airport's PPR requirement is published in its Aeronautical Information Publication (AIP) and on its own website. Requirements vary between airports; there is no single procedure.
- PPR
- Prior Permission Required. Specific approval from the aerodrome operator before an aircraft may land.
- AIP
- Aeronautical Information Publication. The official state publication setting out an airport's procedures, including its PPR conditions.
- PPR code
- A unique reference issued on approval, entered in the flight plan at Part 18 (Other Information).
What happens if permission is refused
A refused PPR is not a minor administrative problem. Without it the aircraft cannot land at the intended airport, and the consequences land immediately.
- Delay or cancellation, the aircraft cannot land at the intended airport at all.
- Cost — rerouting means additional fuel, landing fees at an alternate, and unplanned ground handling.
- Operational disruption — for business and VIP flights, a diversion carries a reputational cost beyond the direct expense.
- Regulatory exposure, particularly where a refusal follows sanctions screening rather than a capacity issue.
EU sanctions screening
This is now the most consequential part of the process, and the part most likely to produce a refusal that cannot be fixed by resubmitting the form.
Under Article 3d of Council Regulation (EU) No 833/2014, EU airports must deny landing permission to aircraft operated by Russian nationals or entities, or aircraft listed in the sanctions directories. Council Regulation (EU) 2022/334 tightened enforcement, and breaches carry substantial penalties.
How approval works at Lithuanian airports
Vilnius (EYVI), Kaunas (EYKA) and Palanga (EYPA) grant prior permission where five conditions are met. The procedure is a useful worked example because it is published in full.
All five must be satisfied
- Every required field on the PPR application form is complete.
- The form is submitted at least 24 hours before scheduled arrival. General aviation flights must file at least 2 hours before departure, unless exempted.
- The aerodrome operator confirms the infrastructure and operational capacity can accommodate that aircraft type.
- No sanctions violation is identified under Article 3d of Regulation (EU) 833/2014.
- No violation of Council Regulation (EU) 2022/334 is detected from the information submitted.
Where all five are met, a unique approval code is generated — `PPREYVI1258`, for instance, and sent to the ground handling provider named on the form. That code must appear in the flight plan at Part 18 (Other Information). Where they are not met, the operator refuses approval and notifies the ground handler of the reason.
Reducing the chance of refusal
- 01Before planning
Read that airport's own requirements
Procedures differ. Check the AIP entry and the airport's site rather than assuming a process you have used elsewhere applies.
- 0224h+ before arrival
File a complete form
Incomplete applications are the single largest cause of refusal — applicant, operator, flight details and ground handler all have to be right.
- 03Before filing
Screen for sanctions exposure first
Operator, registration and ownership chain. This is the failure that cannot be fixed late.
- 04Always
Leave margin
24 hours is a minimum, not a target. Filing at the minimum leaves no room to correct anything.
Common questions
What does PPR mean in aviation?
PPR stands for Prior Permission Required. It means an aircraft may not land at that airport until the aerodrome operator has granted specific permission for the flight.
How far in advance do I need to apply for PPR?
Most airports require at least 24 hours before scheduled arrival. At Lithuanian airports, general aviation flights must submit at least 2 hours before departure unless exempted. Individual airports may require longer, so check the AIP.
What is a PPR code?
A unique reference issued when permission is granted — for example PPREYVI1258. It is sent to the ground handling provider named on the application and must be entered in the flight plan under Part 18, Other Information.
Why was my PPR application refused?
The two usual causes are an incomplete application form and sanctions screening. Under Article 3d of Regulation (EU) 833/2014, EU airports must refuse aircraft operated by Russian nationals or entities, or aircraft on the sanctions lists. Capacity constraints at the airport are a third, less common reason.
Do all airports require PPR?
No. It applies where the aerodrome operator has imposed it, which is published in the airport's AIP entry. Requirements and lead times differ between airports, so a procedure used at one is not a guide to another.
Can a refusal be challenged?
It depends on the reason. A refusal for an incomplete form or a capacity issue can often be resolved directly with the airport. A refusal on sanctions grounds is a legal question about the operator and ownership structure, and needs addressing before the flight rather than after.
