Preamble
The Global Navigation Satellite
System (GNSS) offers position location information suitable to support
precision approaches with operating minima approaching a DH/RVR of 200
feet / ½ mile to virtually every runway end in the world.
With the provision of Augmentation
Systems that supplement the basic system, notably with respect to integrity
and redundancy (see Policy 30-4), GNSS will support precision approaches
to minimums lower than Category I (200 feet, ½ mile).
Studies of approach and landing
accidents have shown that considerable safety benefits can be achieved
by the establishment of instrument and precision approach procedures using
GNSS.
Policy
To further improve safety,
IBAC supports the development and implementation of RNP- based approach,
landing and departure procedures using GNSS.
The priorities of business
aviation for the implementation of such GNSS procedures are:
· non-precision approaches
with vertical guidance (NPAV) for all runways currently lacking an instrument
approach and runways with an instrument approach based on an NDB and/or
VOR where, particularly during night operations, vertical guidance will
provide a significant improvement in safety.
· At those airports
where a more expeditious approach procedure can reduce weather-related
arrival delays and/or increase traffic flow with the use of a straight-in
approach.
· Instrument departure
procedures.
· Precision Approach
Category I (Cat I) approaches for runways not currently provided with
ILS and where users require Cat I operating minima.
