Drone Filming in Nepal

The geography makes it harder than most places. The capital sits inside controlled airspace. Mountain flight routes run low through the same valleys you want to shoot. Parks, heritage sites and border districts each have their own gatekeeper. Above about 4,000 metres the air is thin enough that lift, endurance and climb margin all fall away, and the aircraft has far less in reserve than the spec sheet suggests.

This page covers how permission is structured in general terms, what the machine will actually do at altitude, where aerial work is and is not appropriate, and what we shoot instead when the answer is no. We do not tell productions an approval is certain, because it never is. What we can do is start early, read your specific shots honestly, and build a schedule that survives a refusal.

There is no single drone permit in Nepal, in the same way there is no single filming permit. What you need is a set of permissions that sits on top of, and depends on, your underlying film permission. The aircraft and the airspace are governed by the civil aviation authority. The ground beneath the aircraft is governed by whoever controls that ground: a district administration office, a local police post, a national park, a conservation area, a heritage trust, or the security apparatus around a barracks, a border or a hydropower scheme. A single flight over a single valley can touch several of those at once.

That structure has two consequences worth understanding before you brief anyone. First, the drone application cannot really begin until the shoot itself is defined, because the aerial permission hangs off the film permission and off named locations, dates and aircraft. Second, permission to film in a place is not permission to fly there, and permission to fly nationally is not permission to fly at a specific site on a specific morning. The categories, the height ceilings and the routing have all been revised more than once, and they will be revised again. We confirm the current position with the relevant authorities for your shoot rather than repeating what was true last season. Anyone who quotes you a fixed rule from memory is quoting you a rule that may already have changed.

Some airspace is closed, and no application changes that. Tribhuvan International sits inside the Kathmandu bowl, so much of the capital is controlled before you consider anything else. Pokhara, Bhairahawa, Biratnagar, Nepalgunj and Bharatpur repeat the problem on a smaller scale, each throwing a controlled zone across the town around it. If your establishing shot is a city, assume the honest starting position is no, and that any exception is a specific, conditional approval rather than the default.

Mountain strips are worse than they look on a map. Lukla, Jomsom and Simikot take heavy short-field traffic with no radar, flown visually down the middle of the same valley you want to cross. Rescue and charter helicopters work the Khumbu and Annapurna corridors low all morning, which is exactly when the light and the air are best for you. Putting an uncrewed aircraft into that traffic is not a paperwork problem, it is a safety problem, and it is treated as one.

Then there are the places where the sensitivity is cultural rather than aeronautical. The Kathmandu Valley heritage sites and Lumbini are controlled separately from ordinary airspace, and at a site like Pashupatinath the more sensitive question is filming at all, before you even raise a drone. Border districts and army ground are effectively shut. None of this is hostility. It is the ordinary shape of the country’s airspace and its sensitivities, and the sooner your shot list is measured against it, the fewer surprises you carry into the shoot.

Altitude is the part productions consistently underestimate, because the aircraft looks the same on the ground at 4,500 metres as it did at home. It does not fly the same. Air density is roughly two thirds of sea level at 4,000 metres and closer to half by 6,000. The rotors have less to bite on, so they work harder for the same lift, current draw climbs, endurance drops, and the margin you keep in reserve for a climb or a fast reposition gets thin. Manufacturers publish a service ceiling and sell high-altitude propellers, and both help, but treat the ceiling as a hard limit rather than as performance you will actually get. The last few hundred metres of any published figure are not where you want to be operating.

Cold complicates it in two directions. Cold air is denser, which is mildly in your favour for lift. It is against you everywhere else. Lithium cells lose usable capacity below freezing and sag under load, and load is exactly what you are asking of them at 4,500 metres at first light. Keep packs warm overnight and bring them up to temperature before you fly, not after you have launched. Deep valleys add their own problems: they break line of sight in seconds as the aircraft drops behind a spur, and the steep walls give poor satellite geometry, which degrades the aircraft’s own position hold. The working conclusion from all of this is simple. Plan short flights and more of them, keep the aircraft close and high in your sightline, and never build a sequence that needs the machine to perform at the very edge of what the specification claims.

In the high valleys the wind behaves like a clock rather than a forecast. Overnight the air is usually still. As the sun hits the slopes the valley heats, air moves up-valley, and by late morning it is often too strong to fly usefully or safely. Dawn to mid morning is the window, and it closes earlier the higher and narrower the valley is. That single fact reshapes an aerial schedule more than most producers expect, because it means your best light and your only reliable flying air are the same ninety minutes, and you cannot spend them setting up. The aircraft has to be built, checked, warmed and briefed before first light.

Season sets the rest. October and November, once the monsoon has cleared, generally give the cleanest air and the most dependable mountain visibility, which is why they are also the busiest weeks in the country. March and April give longer days but haze builds through the pre-monsoon weeks as dust and smoke accumulate, and afternoon cloud develops over the peaks. Winter is clear, cold and short: excellent visibility, brutal on batteries, and with valley fog that can delay the very morning flights you were counting on. The monsoon, broadly June to September, brings low ceilings and days when the mountain is simply not there behind the cloud. We build aerial days around the morning window and the season you are shooting in, and we will not promise you a clear peak on a named date, because no one honestly can.

The places most people want aerials of are, more often than not, the places where aerials are hardest to clear. National parks and conservation areas are the clearest example. Entry for your people and permission to film are already two separate questions there, and airborne work is a third, sitting on top of both and frequently refused outright. The concern is not bureaucratic. Low-flying aircraft disturb wildlife, and around any area with rescue and expedition traffic there is genuine sensitivity about drones sharing the airspace. In Sagarmatha in particular you are dealing with a narrow corridor used by rescue and charter helicopters flying low and often, and with real feeling among expedition teams and climbers about drones near the base camp area. We will put an application in where it is worth putting in, and we will tell you plainly when the honest answer is that it is not, and what we would shoot from the ground instead.

Heritage and religious sites carry a different weight. A monastery answers to its abbot and its committee, not to a ministry, and a drone over monastery grounds during a ritual is a matter of courtesy and consent, not a form you can file your way past. Religious ceremonies, funerals and private houses are the usual flashpoints, and a national approval does nothing to soften a local objection at any of them. The work that keeps a flight out of trouble happens the day before, on foot, in Nepali, with the people who actually live and pray in that place. It is slow, unglamorous groundwork, and it is the single biggest difference between an aerial day that goes smoothly and one that ends with a crew being asked, fairly, to land.

There is one decision on an aerial shoot that is never worth getting wrong, and it is the temptation to fly anyway. When an approval has not arrived, or a local objection lands on the morning, the pressure to launch is real: the crew is at altitude, the day is expensive, the light is perfect. Flying without permission risks the aircraft, risks the pilot, and risks the rest of your permissions for the entire shoot, because one uncleared flight in the wrong airspace can put every other approval you hold under question. No single shot is worth that trade, and a good operator will refuse it on your behalf when you are too invested in the day to refuse it yourself.

Safety also drives who flies and how. Approvals are normally issued against a named airframe and a named pilot, so assume that changing either means going back to the authority rather than flying on the paperwork you already hold. A visual observer is not a courtesy on the busy mountain corridors, it is the person watching for the rescue helicopter you cannot hear over your own rotors. Third-party liability insurance covering the aircraft is part of a serious application, not an extra. And the whole operation lives or dies on line of sight and reserve, which is why we plan short flights, keep the aircraft close, and treat the published service ceiling as a wall rather than a target. The aim is not to extract the maximum from the machine. It is to come home with the shot, the aircraft and the rest of your permissions intact.

A drone is a tool for a particular kind of information, and it is worth being honest about when that information matters and when it is habit. Aerials earn their place when the story is the shape of the land: a river system read from above, the scale of a terraced hillside against the peak behind it, a settlement isolated in a fold of the mountains, a route traced across a pass that no ground frame can hold in one image. They earn it in movement that reveals, where the reveal is the point rather than decoration. Used that way, a single aerial can do work that a day of ground coverage cannot.

They do not earn their place when they are a reflex. An establishing drone shot over a town you could not otherwise justify flying over, a slow rise up a building for no reason the edit needs, a hover that a locked-off wide would serve better: these are the aerials that cost you permission effort, altitude risk and schedule slack for a frame the film would survive without. In Nepal, where every aerial carries a real chance of refusal and a real safety overhead, that calculation matters more than it does at home. We would rather help you spend your aerial budget on the three shots that carry the film than on twelve that decorate it, and we will say so when we think a shot on your list is habit rather than need.

Our job on aerials is not to promise you the sky. It is to tell you the truth about it early enough to act on. That means taking your shot list apart before anything is submitted, being blunt about the shots we think will not clear, and putting the same effort into the ground alternative as into the flight itself. It means starting the drone application in parallel with your film permission, filing locally and chasing in person, and keeping you informed about where each approval stands, including when it is stuck. And it means doing the quiet, unglamorous groundwork the day before, on foot and in the local language, that turns a piece of paper into a flight nobody objects to.

We will not describe a shoot as something it is not to move an application, and we will not tell you a shot is cleared until it is. We will not run a flight on the assumption that no one will ask, because the consequences of an uncleared flight do not fly home with you. They stay with the local company whose name is on the file and with the Nepali crew who live and work here afterwards. That is the same standard we hold across every part of a shoot, and it is why the honest answer, even when it is no, is worth more to your film than a cheerful yes that falls apart on the day.
