MPP-02.3.7 cross-deck operations with armed rotary wing aircraft

What it is

What MPP-02.3.7 covers

MPP-02.3.7 is a NATO Multinational Procedural Publication (MPP) that supplements MPP-02, Volume I, Helicopter Operations From Ships Other Than Aircraft Carriers (HOSTAC), with "common planning and operating considerations for cross-deck operations with armed rotary wing aircraft of another nation". Nations agree to use its "Aide Memoire for planning operations with armed helicopters from another nation" rather than adopt a shared technical specification: the publication is a planning checklist, "designed to supplement individual nations planning processes to ensure operations with armed rotary wing aircraft are safe", not a set of engineering or flight requirements of its own. It is covered by STANAG 1487, the agreement by which NATO nations commit to use it.

What the checklist asks

Clause 0104's Aide Memoire works through sixteen planning considerations for a cross-deck operation, set out as questions rather than instructions, "designed to provide a common approach and assist the participating nations, conducting cross-deck operations, to prepare for the considerations of armed rotary wing aircraft". It prompts task group command and the two nations' planning staff to confirm, among other things: whether the operational need and its implications are understood at task group command level; how the carried explosive ordnance is classified, referencing the Hazard Classification Code in AASTP-3 and the Net Explosive Quantity in AAP-15; how the aircraft's own safety arrangements and the receiving ship's handling capability match up; the response planned for a hung weapon or an unauthorised discharge; and the fire-fighting and radiation-hazard considerations that follow from carrying ordnance and electro-explosive devices. It also asks whether deck teams, helicopter control officers and marshallers have been briefed on danger zones and their own responsibilities, whether the ship's approach and recovery geometry suit the aircraft's forward-firing arcs, whether the aircraft's weapon and ammunition standard operating procedures have been shared with the ship, and whether each nation's own approval process and a documented risk assessment cover the operation. MPP-02.3.7 does not answer these questions itself: it leaves the technical judgement on ordnance handling, arming, and flight profile to the two nations' own qualified personnel and command chain, and this page does not either.

Who it addresses, and what it does not settle

The publication addresses "individual nations planning processes" and task group command, not a supplier or a manufacturer. It says nothing about who audits or certifies against it: "the procedures are based on a checklist format", completed and signed off within the participating nations' own process rather than assessed by any accredited or notified body. It sets no retention period for a completed checklist and no rule for what happens if a nation's answer to a consideration falls short; those are left to the nations involved.

MPP-02.3.7 is published by NATO and listed free of charge in the NATO Standardization Document Database. NATO's documents are not sold by ComplyTrain and we host no copies of them.
