The short answer
You apply online on the CAASL Drone Flight Approval Portal, with your pilot details, your drone details and the documents listed below. CAASL forwards the application to the Ministry of Defence for security clearance. If you want to fly in a restricted area, an archaeological site or a wildlife area, you need extra approvals as well.
Before you apply
The current CAASL standard also asks for these, so sort them out first:
- You are registered with CAASL as a drone pilot and hold a Flyer ID, which you get by passing its online training and theory exam. This applies to visitors too.
- Your drone is registered with CAASL. Drones with a camera need registration even under 250 g.
- Your drone has public liability insurance if it weighs 250 g or more.
- You know the exact places you want to fly, with an address or GPS location for each.
Read the full Sri Lanka drone rules for the details behind each point.
Step 1: Check the drone zone map
Open the CAASL drone zone map and look up every place you plan to fly. It shows restricted, authorisation, altitude and warning areas. This tells you if you need extra approvals in step 2, or if a place cannot be flown at all.
Step 2: Get any extra approvals
- Restricted areas: no drone may fly there on a normal clearance. For a real need, ask the Ministry of Defence for special clearance at least 14 days before the flight.
- Archaeological sites, such as Sigiriya: get a special approval or no objection letter from the relevant authority, such as the Department of Archaeology.
- Wildlife sanctuaries, national parks and forest reserves: get approval and a no objection letter from the authority that manages the area.
- Airports: flights inside an airport zone on the map need approval from that airport's air traffic control.
- Private property, hotels and venues: get permission from the owner or management.
- Public areas, for commercial flights: get a no objection letter from the police.
Approval letters should show the dates, times and the drone operator's details. The Ministry of Defence publishes a sample no objection form.
Step 3: Prepare your documents
For a leisure flight (holiday, personal use)
- The completed online application
- A copy of your passport biodata page (Sri Lankans can use their National Identity Card or driving licence)
- Your full name without initials, exactly as it appears in your passport
- The address or GPS location of each flight
For a commercial flight (paid work, clients, brands)
- The completed online application
- A request letter from the client on company letterhead, with the location, date and time of the flight and the drone operator's details
- A copy of the operator's passport biodata page, National Identity Card or driving licence
- Approvals or no objection letters from the relevant authorities, such as the property owner or management, and the police for public areas
- The details of every pilot and every drone taking part, all in one application
The Ministry of Defence says a commercial flight must never be declared as a leisure flight.
Step 4: Apply on the CAASL portal
Go to the CAASL Drone Flight Approval Portal. The portal asks you to check the map, fill in the application with pilot and drone details, then upload your documents and wait for CAASL approval.
Step 5: Wait for security clearance
You do not apply to the Ministry of Defence yourself. It only gives security clearance for applications that CAASL forwards through the portal. The Ministry's drone section works on working days, Monday to Friday from 08:30 to 16:15, and not on government holidays. Applications sent at the weekend are handled on the next working day. If other government bodies must approve, it takes longer.
There is no published processing time, so apply as early as you can. Do not fly until your approval arrives.
Step 6: On the day
- Carry your approval, proof of drone registration and your Flyer ID.
- Fly only at the places and times in your approval.
- Follow the flying rules: 120 m maximum height, keep the drone in sight, daylight only, no flying over crowds, and no flying in rain or strong wind.
Special operations, such as drone swarms, follow CAASL publication SLCAP 4620 and must reach the Ministry of Defence at least three weeks before the flight.
Who to contact
- CAASL: the drones page has forms, contact details and updates.

Questions
Is there a fee?
The standard says drone registration and the Flyer ID are issued on payment of a set fee. Check the current fees on the CAASL website, as they can change.
How early should I apply?
As early as you can. There is no published processing time, approvals are handled on working days, and clearance for restricted areas must be requested at least 14 days before the flight.
Do I need a permit to fly indoors?
The standard says its approval requirement does not apply to flights inside a building or private home. You still need the owner's permission.
Can someone else fly for me instead?
Yes. A local operator with registered drones can fly for you and handle the approval as the operator. See our drone filming services.
