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
