Lao Aviation Payment Tracking System
Flight permission, movement and payment in one place
APS carries a flight from the permission request through to the receipt. One request covers a whole season, the flights actually flown are matched against it, and the invoice that follows shows the movements it was built from.
Used by carriers, general sales agents and DCAL
- Landing permission
- Overflight permission
- Decided in 24–48 hours
About APS
Aviation Payment System (APS)
A single digital counter for flight permission applications, actual flight movement, billing and payment. It replaces the letters, spreadsheets and counter visits that used to sit between an airline and its permit, and leaves one record that the airline, its agent and DCAL all read from.
Built by AIDC Tech Sole Co., Ltd. — digital transformation for government — for the Department of Civil Aviation of Lao PDR.

How APS works
Five steps, one record
Each step hands the next one its data, so nothing is re-typed and nothing has to be reconciled afterwards.
Step 1
AIP Lao PDR
Start from the rules. The Aeronautical Information Publication sets what a request must carry — route, aircraft, documents — before it is worth filing.
Step 2
Request flight permission
File one request for a landing or an overflight covering a whole season's schedule. It is checked, decided, and answered with a permit number.
Step 3
Actual flight movement
The flights actually flown arrive from the air traffic feed and the AFTN flight plans, and are matched to the permission they flew against.
Step 4
Billing
Matched movements are rated against the published tariff and gathered into an invoice that shows every flight behind the figure.
Step 5
Payment
Pay by bank transfer or at the counter, declare the payment in the portal, and download the receipt once finance has verified it.
Track your request
Where is my flight permission?
Enter the reference printed on your request or permit and pick up where you left off.
Why choose APS?
What the portal changes
The same work, without the counter queue and without the second copy of the truth.
One-stop digital service
File, track, pay and download from anywhere. No counter visit, no couriered paper, no office hours.
Signed and verifiable
Permits and receipts are issued under the operator's own signature and can be checked back against the system that issued them.
Fast and traceable
Ordinary decisions in 24–48 hours, with every step timestamped, so a delay always has a name and a place.
Support when you need it
The APS desk answers by email and by phone, and every question can be tied to the request it is about.
FAQs
Questions we are asked most
How do I get an APS account?
Accounts are issued by DCAL rather than opened by self-service. Write to the address below with your company name, the contact person, an email address and phone number, and your operating documents — an air operator certificate for a carrier, or the appointment letter for a general sales agent. Once those are checked your first user is created and a temporary password is sent to the contact email; you set your own password at first sign-in.
What kinds of flight permission can I apply for?
Landing permission and overflight permission, for both scheduled and non-scheduled operations. One request covers an entire season's schedule rather than one flight at a time, and a general sales agent can file on behalf of the carrier it represents.
How long does a decision take?
Ordinary requests are decided within 24–48 hours of a complete filing, and a request marked urgent is queued ahead of them. Time spent waiting for a missing document does not count towards that window, which is why the request lists what it is still missing.
My request was refused. Can I correct it and file again?
Yes. A refusal carries its reason with it. Editing a submitted request returns it to draft under the same number, so the history stays in one place, and it re-enters the queue when you submit it again.
How do I pay, and when do I get the receipt?
Invoices are raised from the flights actually flown and are payable by bank transfer or at the counter. Declare the payment in the portal with the transfer slip attached; the receipt is available to download once finance has verified it.
Who do I contact for help?
The APS desk, on the email address and phone number in the footer. For anything about a specific request, quote its reference number.
