Why layered deterrence
No two airports have the same bird problem
Birds come to an airfield for food, water, shelter and roosting, and each species has its own habits and seasons. Pakistan has an obligation under ICAO Doc 9137, Part 3 (Bird Control and Reduction) to discourage hazardous birds on and around its airports.
Habituation is the main enemy. Long-term results come from habitat modification combined with deterrents birds do not get used to.
Reach
How far each method works
Close-range devices protect fixed zones; lasers and pyrotechnics reach birds over the approach and far end of the runway.

Acoustic devices
Bird Collision Avoidance System (BCAS)
Interconnected modules that detect, recognise, monitor and log birds, then deter them with a focused sound signal.
Thermal camera
- Up to 360° panoramic coverage
- Day and night, all weather
- Tracks multiple birds
- Detects approaching aircraft
Control module
- Receives, stores and processes detection data
- Controls all modules
- RF link between units
- Remote operating modes
Acoustic module
- Acoustic startle reflex, 300 ft coverage
- Unique sound wave, no habituation
- Short sound, minimal noise disturbance
- Focused at targeted birds
Acoustic devices
Radio remote-controlled gas cannons
Several very loud bangs scare birds away from the area around the unit. Operated by radio remote so they fire only when needed, keeping nights quiet. A vehicle-mounted cannon can respond wherever birds gather, in coordination with ATC.
- Up to 146 dBper bang
- 360° · 8 hathree blast tubes cover 80,000 m²
- Remoteradio control unit
Laser techniques
Aerolaser handheld & automated lasers
Birds see the approaching beam as a physical danger and fly away, the same reflex as when a car approaches. Unlike conventional methods, birds do not get used to it. Automated systems claim the territory 24 hours a day, 7 days a week.
- 2,500 mhandheld range
- Up to 90%reduction in bird nuisance reported by airports and helipads
- No harmto birds
Pyrotechnics
CAPA bird-scare cartridges
Fired from a hand-held aviation-grade launcher. The rocket motor is silent on discharge, so the cartridge reaches its detonation range undetected and the bang comes as a surprise. Suited to the approach funnel and birds flying 200 to 800 ft up.
- ≈1,000 ftdown range before the report

Chemicals
Taste-aversion repellents
Food-grade products sprayed onto surfaces with a pump sprayer to make roosting and feeding areas unattractive. They can be sprayed onto nests, structures and tree branches and do not harm the environment, vegetation or people.

- Ongoinguse keeps birds from returning
Bird spikes
Stainless steel bird spikes
Birds avoid landing on spikes, which makes them very effective on linear surfaces: runway marking boards, fences, DVOR structures and building edges where birds perch, roost and nest.

- All weatherprofessional finish

Horizon Safety System™
Ten modes: −30°, −20°, −10°, −5°, 0°, +5°, +10°, +20°, +30° and off. Each limits how far above horizontal the beam can be shone, preventing it reaching aircraft, pilots and passengers.
Most effective at sunrise, sunset and in overcast, rainy or foggy weather. Never point at people, vehicles, buildings, aircraft or reflective surfaces.
Proven in Pakistan
We surveyed JIAP for the Civil Aviation Authority
Our 2016 study mapped bird hotspots around Jinnah International Airport and set out where each deterrent should go.
