LuftforsvaretLuftoperativt inspektoratLuftrom & Flyplass The Military in SES

(Mil aviation exempt from SES regulations)

• The military role is complex– protect their national territory including airspace– Constant military presence and daily access to airspace

• Including cross border (NATO/EU/Coalitions) and outside Europe

– Military roles; Airspace Users, Air Navigation Service Providers (not Norway), Airports operators, Regulators (MAA) and Policy Makers (MoD)

• Two major airspace users; civil and State aviation– Military aviation responsible for operations and training in order

to deliver security and defence.– States must safeguard both civil and military aviation

requirements.– Cooperation between Military and Civil aviation is essential to

meet SES goals– Any development in ATM must take military requirements fully

into account

Military use of WAM and GNS(use and “Pros”)

Mil use: Navigation, Surveillance and Weapons (Air/Ground)

•Cost effective:• Simple ground infrastructure compared to current technology• Low maintenance cost

•Flexible:• Can be used both as surveillance and navigation service• Easy to establish service at new location/base

•Accurate:• Services are accurate world-wide• Services can be used to verify/update navigation accuracy

Mil use when deemed beneficial to meet military requirements and civil integration needs (safety)

• Vulnerable:

• Services can be put out of commission “very easy”

• Aircraft battle damage can make services unavailable to that user

• Interdependencies:

• Use of services dictates strict standards of equipment (duplication civ/mil systems)

• Aircraft navigation accuracy is part of surveillance accuracy (safety)

• Non-cooperative targets:

• Depends of cooperative targets for surveillance services (Security)

• Primary radar(PSR) and other sensors will still have to be used

Military use of WAM and GNS (Cons)

Mil limited use due to need for secure, resilient and robust ATM system to guarantee the efficient conduct of security and defence missions

• Ensure early cooperation in development of regulations (EASA, CAA/MAA, MoT/MoD etc)

• Establish Common Military Positions (CMP) in Europe (NATO, Eurocontrol, EDA)

• Plan and invest in new (SES) technology:• Ensure that Military will be “as military as required,

as civil as possible”– This means that Military will be as compliant as possible

but ensure military needs (Security, OPS requirements), but;

– may seek to use equivalent performance levels (mil systems recognized as equivalent)

– or exemptions when deemed necessary.

Mil strategy for SES/SESAR

The aim is to ensure that Military aviation can operate safely and effectively alongside the regulations of SES (both GAT and OAT)
