  • Why Tivat Airport Has a Bird Problem — And Why It’s Getting Worse

    Why Tivat Airport Has a Bird Problem — And Why It’s Getting Worse

    On July 24, 2026, Tivat Airport (TIV) ground to a halt. For over three hours — from 07:40 to 11:00 local time — no aircraft could land. Air Serbia, Air Montenegro, easyJet, Turkish Airlines, Eurowings, Israir, FlyOne and Norwegian Air Shuttle were all forced to divert to Podgorica, Tirana, Brindisi, Rome and Bari. Airport authorities cited an “unprecedented concentration of birds on the runway.”

    It wasn’t a one-off. Bird-related incidents at Tivat have been climbing steadily: confirmed bird strikes rose from around 5 in 2023 to 17 in 2024, while total bird-related airspace events rose from 26 to 38 over the same period. Recent years have seen strikes on an EasyJet A320 (June 2024) and a SmartLynx A320 (2023), among others. The trend line points in one direction — and the causes are not mysterious.

    A wetland the airport can’t touch

    Tivat’s runway sits on reclaimed coastal land in the Grbalj valley, at the edge of the Bay of Kotor, with the runway threshold just 88 meters from the shoreline. Immediately adjacent is Solila, a roughly 150-hectare former salt-pan wetland that has been a protected nature reserve since 2007 and a Ramsar-listed Wetland of International Importance since 2013. It hosts more than 100 bird species — flamingos, herons, cormorants, egrets, birds of prey — and serves as a resting point on the Adriatic migratory flyway between Africa and northern/eastern Europe.

    This is a structural, largely irreducible constraint. Solila is legally protected; the airport cannot disperse, drain, or disturb it the way it might a patch of unprotected scrubland. Coastal wetland and flight path were always going to overlap here.

    An illegal landfill the airport absolutely can touch

    The more troubling factor is different in kind. It has been identified as an illegal dump directly adjacent to the airport, on land owned by the company Montepranzo Bokaprodukt but used by the municipal utility Komunalno Tivat. Estimates put the volume at more than 5,000 cubic meters of waste, much of it organic — precisely the kind of food source that draws large, persistent gull and scavenger-bird flocks onto an active runway.

    The site reportedly began under a temporary business agreement permitting limited transfer of waste pending a permanent municipal disposal location. That agreement has since lapsed, according to the landowner, yet dumping has continued. Montepranzo Bokaprodukt has formally notified the Tivat municipality, Montenegro’s Ministry of Ecology, Sustainable Development and Development of the North, the Ministry of Tourism and Transport, the Civil Aviation Agency, the Environmental Protection Agency, Airports of Montenegro, and environmental inspectors. Montenegro’s flight control agency has separately flagged the safety risk to the relevant authorities.

    Unlike Solila, this is not a conservation trade-off — it’s a jurisdictional and enforcement gap between a private landowner, a municipal utility, and multiple state bodies, all of whom appear to have been warned before the July 24 shutdown.

    Already on the official record

    This isn’t a hazard that caught anyone by surprise on paper. Montenegro’s Aeronautical Information Publication (AIP), in the AD 2.LYTV aerodrome section, carries a standing caution:

    “Maintain a careful look-out on APCH and DEP because of mountainous area close to AD. Birds in vicinity of AD.”

    Jeppesen charts for LYTV carry the same warning in shorthand, printed directly on the airport diagram: “Birds in vicinity of apt.” This is a permanent aerodrome remark, not a one-off NOTAM — every crew flying into Tivat is briefed on it as a matter of course, and has been for years.

    Two different problems, one runway

    Map showing Tivat Airport with Solila to the southwest and the reported landfill site to the southeast
    Tivat Airport (TIV): Solila nature reserve sits southwest of the runway, by the coast; the reported waste site sits southeast, adjacent to the road toward Kotor — flanking the approach/departure path from both sides.

    The result is that Tivat effectively has two bird-attractant systems stacked on top of each other at the exact moment traffic is at its seasonal peak — 2024 passenger numbers were up 32.5% year-on-year, and summer accounts for roughly 80% of annual volume. Airports of Montenegro says it applies radar-based detection and standard dispersal measures, but detection and dispersal can only do so much against a food source sitting a few hundred meters from the threshold.

    Solila will remain a fixture of Tivat’s operating environment; that trade-off is the price of a genuinely scenic, biodiverse coastline. The landfill is the part of this story that has a straightforward fix — if the responsible authorities act on the warnings already on file.

  • EASA Releases New Tool to Assess Noise Levels of Light Propeller-Driven Aeroplanes

    EASA Releases New Tool to Assess Noise Levels of Light Propeller-Driven Aeroplanes

    The European Union Aviation Safety Agency (EASA) has released ENCODE — the EASA Noise Compliance Demonstration Evaluator — a new tool designed to calculate noise levels and confidence intervals from noise testing data for light propeller-driven aeroplanes.

    What ENCODE Does

    ENCODE is a Microsoft Excel-based tool that processes data measured during noise tests conducted under Chapter 10 of ICAO Annex 16, Volume I. It validates each individual test run against environmental and performance limitations, then standardizes how the resulting noise levels are determined and reported.

    Why EASA Built It

    According to EASA, the tool is meant to:

    • Harmonize noise reporting for light propeller-driven aeroplanes, as required under EASA’s Environmental Requirements
    • Reduce the workload for applicants and noise experts carrying out compliance demonstrations
    • Ensure a consistent methodology is applied across noise assessments industry-wide

    Where to Find It

    ENCODE and its accompanying User Guide are available on EASA’s website, under the “Light propeller-driven aeroplanes” section of the Environment domain (Technology / Aircraft Noise and Emissions Data).

    The release is part of EASA’s broader environmental protection framework for general aviation, aimed at making noise compliance demonstrations more consistent and less burdensome for manufacturers and testing organizations alike.
