Every flight crosses a sequence of countries. Each one sets its own permit conditions.
Amsterdam to Seoul crosses twenty-two flight information regions in thirteen countries: overflight permits along the way, and a landing permit at the destination. Air Permit Planner reads your schedule, checks every flight against every permit rule, and keeps the permit record in one place as the schedule changes.
For permitting and flight operations teams at cargo, charter and scheduled airlines, and the planning teams whose schedules they cover.
Amsterdam to Seoul
One flight, and the airspace it crosses
Works from the schedule you already have.
Flights are read on a continuous feed from your data lake, where the schedule and the filed flight plans already arrive. Each flight is matched against the permit rules your permitting team has defined, authority by authority. Click a box to see what it does.
Every flight, every permit rule, every change. Holds the permit record and runs the checks that keep it current.
Here is a flight into Seoul, from Singapore, with its own permits to hold.
One flight, followed through the permitting process end to end: the schedule comes in, a gap is found, an application goes out, the approval comes back, the schedule changes, and the record is kept current.
-
The row already carries every airspace the flight crosses, with the state of the permit for each. Nothing is typed in: the airspaces come from the filed flight plan, the permit states from the record.
-
Six airspaces are covered by permits on file. Vietnam is not, so the flight is not valid yet. The requirement says what the authority asks for, and the application can be drafted from it.
-
On your template, with the flight details taken from the schedule: registration, dates, times, entry and exit points. Downloaded, sent from your mailbox, and marked as sent.
-
The reply is dropped into Record. The tool reads the letter and proposes the entry: authority, permit reference, validity window, approved registration and flight numbers.
Nothing is filed until your permitting team has checked the proposal against the letter and confirmed it. The permit is attached to the flight it covers, and marked as valid.
-
The change arrives on the same feed. Some permits cover a whole season. Others hold for one registration, one validity window and set entry and exit points, so a delay, a tail swap or a routing change can put a flight outside its permit.
It is flagged, with the reason, and the permitting team decides: reapply, amend, or override. The team always has the final say.
-
Every flight, every permit and its current state are visible on one board. It can be filtered and exported, and the permit state can be written back to the data lake, so that the permit record sits next to the schedule it belongs to, for any system that needs it.

Checking every change against every rule sits with the tool, so that your permitting team's time goes to the decisions.
Your permitting team sets them, authority by authority.
Seasonal or per flight. Direct or through an intermediary. Lead times, documents, what a permit fixes: registration, validity window, entry and exit points. The tool applies them; it does not invent them.
One authoritative place for every permit and its state.
Required, drafted, sent, pending, valid, expiring, not valid. Attached to the flights it covers, with the letter behind it. Written back to your data lake for any system that needs it.
Nothing is filed without a person's confirmation, and the permitting team can always override.
Proposals from inbound letters are confirmed by a person. Flags from schedule changes are decided by a person. The tool does the reading and the checking, and keeps the trail.
Bring one route and its permits.
A useful first session starts with one schedule feed, one authority's rules and one flight that crosses several. We will show the dossier, the application, the inbound letter, and what happens when the schedule moves.
