What it is
What AATMP-08 governs
AATMP-08 is the NATO Allied Air Traffic Management Publication that carries the technical method behind STANAG 3346, the agreement by which participating nations commit to it. Its purpose is to standardise how obstacles on NATO airfields are marked and lit, giving NATO forces a consistent, maximum degree of safety while keeping commonality with civil practice, specifically the colours and method in ICAO Annex 14, Volume 1 (Eighth Edition, July 2018). That commonality is deliberately not absolute: the document says it "is to be maintained without detracting from the requirement for unique military operations", which is why AATMP-08 also covers things civil aerodromes do not, such as arrester-barrier warning lights.
What counts as an obstacle
AATMP-08 defines an airfield obstacle as "all fixed (whether temporary or permanent) and mobile objects or parts thereof, that are located on an area intended for the surface movement of aircraft or that extend above the clearance planes established by application of the current criteria of the host nation." In practice, whether something counts turns on the host nation's own clearance-plane criteria, not on a fixed height set by AATMP-08 itself. The provisions do not apply to airfields where tone-down measures have already been incorporated.
Arrester barriers and obstacle lights
Elevated arrester barriers count as ordinary obstacles. Net-type barriers additionally need warning lights on the runway installation, projecting into the approach sector, so a pilot can tell that a downwind barrier has been accidentally left up, or that they are lined up to land in the wrong direction. These lights run continuously until the barrier is lowered, on frangible posts 0.9m (3ft) high next to the brake mechanism. AATMP-08 recommends physical checks of the barrier and its warning-light system twice daily and after every change of runway direction. Obstacle-light power supply and control circuitry has to follow the current edition of STANAG 3316, Airfield Lighting; AATMP-08 cross-refers to it rather than restating it.
The safety annex: what to check before you implement
Annex A is written for NATO Led Service Providers implementing the standard at existing or planned airfields, and during deployed operations. Before implementation it expects a check against the NATO Standardization Agency's own records: is the STANAG/AATMP suitable for this type of operation (STANAG 7210 / AEP-68 has the guidance), is the edition and any amendments current, have related documents been obtained and reviewed, what is the ratification status and are there national reservations, and do existing facilities already comply. Alongside that, and regardless of it, AATMP-08 says full safety surveys under STANAG 4720's Air Traffic Management Safety Management System "shall still be carried out".
Hazards a custodian has already flagged
The annex also lists specific hazards identified by the STANAG's custodian and national subject-matter experts, each with a suggested mitigation: LED obstruction lights that are not visible through night-vision goggles (test NVG visibility before deploying LEDs, or use incandescent or NVG-compliant lamps); LEDs that may not generate enough heat to clear snow and ice (confirm cold-weather performance, or use incandescent lamps or heaters); obstruction lights on tall structures that are hard to reach for maintenance (design in access from the start, such as lift trucks, secure pathways, or drop mechanisms); and injury or death to maintenance personnel from electrocution or falls (use qualified personnel, with safety procedures such as fall-arrest systems where appropriate). AATMP-08 is explicit that this list is "by no means exhaustive or fully applicable to all environments or situations".
What it does not cover: a retention period for any of these review or check records, or an approval and sign-off process beyond the checklist itself. Neither is specified.
