FutureAvoid Commercial Cost

Demonstrate that we are minimising spectrum requirement. Spectrum assigned Spectrum required

Are the planning rules over conservative? Do we still need hard pairing ? Do we use the whole band? Can we do with less?

Avoid un-necessary duplication of systems Do we need both ILS and MLS as landing aids? Do we need NDB, VOR, DME, GNSS & INRS for en-

route navigation? Do we need 23cm & 10 cm Radar?

Make decisions and stick to themImplement system changes in

accordance with agreed time schedule

Future What Benefits?

Reduced cost of infrastructure Less on-board co-site issuesReduced cost of aircraft fitReduced maintenance costsKnown timescales for

implementationCredibility
