Costs of Equipment – Air: Although there are considerable savings in ground
infrastructure costs if VORs and NDBs are de-commissioned, there are substantial
airborne equipment costs, particular for GA operators. In the case of airlines, which have
a mandate for RNAV equipage, it is unnecessary to examine the costs. GA, as mentioned
in the scenarios above, currently has an exemption. In order to decommission VORs and
NDBs, and move to a complete RNAV environment, this exemption would have to be
ceased.
Standalone RNAV Equipment is manufactured by; inter alia, Garmin, Bendix King and
UPS Aviation Technologies. Typical sample costs covering the entire standalone RNAV
equipage list include the following:
Apollo GX60 £ 3,000 by UPS Aviation Technologies
KLN900 £ 8,100 by Bendix King
GNS530 £ 8,600 by Garmin
For some GA IFR (Instrument Flight Rules) users, the provision of P-RNAV and RNP
RNAV navigation capabilities will be achieved through these standalone RNAV navigation
units. The cost of a standalone RNAV (including GPS) unit for users in this category is
estimated to be approximately £ 10,000.
For cost analysis, aircraft are grouped into the following approximate categories:
� T0: Very light single engine aircraft / non-powered aircraft;
� T1: Light single engine pressurised aircraft (piston/turboprop);
� T2: Light multi-engine pressurised aircraft (piston/turboprop);
� T3: Large turboprops;
� J1: Light business jets;
� J2: Midsize business jets;
� J3: Commercial jets and large business jets.
The following table 3-17 summarises the assumed component costs for each aircraft
type.
