AFSP-1.4 wildlife strike prevention

What it is

AFSP-1.4, Wildlife Strike Prevention, is a NATO Allied Flight Safety Publication that standardises the measures nations take to avoid collisions between wildlife and military aircraft. Section 1.1 states that the publication's aim "is to standardize the measures to avoid collisions between wildlife and aircraft." It sits under STANAG 3879, the standardization agreement that records nations' commitment to use it, and the current edition, Edition B Version 1, was approved by the nations in the Military Committee Air Standardization Board and promulgated in December 2024, superseding Edition A Version 1.

The publication works by having nations adopt, as far as practicable, the wildlife hazard management standards already set out in ICAO Doc 9137, Part 3, and by translating references to civil aviation authorities into their military equivalent where the two do not map directly - "one acts in the spirit of the ICAO doc 9137 instead of to the letter of the document." Annex B lists the specific terminology and role changes this translation needs, and a nation records any further deviations of its own from the ICAO baseline in the reservations at the front of the document.

AFSP-1.4 binds at the level of nations, not companies. A nation takes the standard on by ratifying STANAG 3879, and the publication itself becomes real only "when a nation has issued the necessary orders/instructions putting the procedures detailed in this standard into effect." It carries no certification or audit scheme of its own, and how fully a specific airfield applies it depends on that nation's own instructions: twelve nations, including Bulgaria, Canada, Denmark, Estonia, Finland, Croatia, Hungary, Italy and Romania, recorded reservations at promulgation, mostly because they lack the radar or national reporting system the exchange requirement assumes.

What section 1.3 asks of a nation

Section 1.3 sets out nine numbered obligations. A nation must manage its military airfields' habitat, infrastructure and human activity so the site is unattractive to hazardous wildlife (point 1), assess the wildlife hazard "on a permanent base, using the Safety Management System approach" and work to minimise it (point 2), and restrict activities and land-use practices near an airbase that increase the risk of a strike (points 3 and 4). Each airbase must be staffed with a Wildlife Control Unit responsible for the hazard, whose personnel are competent, educated, trained and properly equipped to monitor, assess and manage it (point 5) - an auditor looking at this clause would ask for the unit's staffing and training records, not for a description of how it does its work. Section 1.2 adds that wildlife strike prevention should serve the environment alongside flight safety wherever the two are not in conflict.

How nations standardise reporting with each other

The remaining obligations in section 1.3 are about exchange between nations rather than airfield management. Nations agree to provide bird strike warning information to the flying community as a BIRDTAM or a NOTAM (point 6), and where a defined bird-intensity threshold is reached, on a scale running from 0 ("Nil") to 8 ("Extremely great") - referred to in one nation's reservation as "the 0-8 taxonomy specified in AFSP-1.4, paragraph 1.3.7" - they must exchange that information with neighbouring countries in the format Annex A sets out: an issuing station, a validity window, the intensity, a geographic reference taken from the low-flying chart, the hazard's lower and upper height limits, and additional information. Nations also agree to calibrate the information they disseminate this way (point 8) and to collect, document and identify evidence from strikes for reporting purposes (point 9).

Annex B separately maps a handful of ICAO Doc 9137 civil terms onto their military equivalent - adding "Military Aviation Authority" to the glossary in place of "Civil Aviation Authority," for example - and, in one case, loosens rather than tightens the underlying ICAO wording, changing a "should include" list of national-committee representatives to "may include."

What the standard does not cover

AFSP-1.4 is a standardization agreement, not an operating manual. It states what a nation's airfields and reporting must achieve, and it leaves the detail of how a hazard is actually managed on the ground, and any specific method used, to the nation's own procedures and to ICAO Doc 9137 itself. It names no certification scheme, no accredited body and no notified body: the only mechanism the text describes is a nation issuing its own implementing orders, and the Record of Reservations shows that what a specific nation actually applies can already fall short of the full text.
