Safety AnalysisSafety Analysis
Some airports will require a statistical safety case to ensure combined error budget will not exceed protection limits, e.g. Cape Town
Safety analysis will provide basis for FAA/CAA approval, if waivers are required

GNSS/RNAV SIDS and GNSS/RNAV SIDS and STARSSTARS
SIDs using PANS-OPS criteria for each identified runway and developed to accommodate the broadest range of aircraft
STARs providing a standard routing for aircraft entering busy terminal areas integrated into existing ATC structure as required
Based on optimal criteria as identified in PANS-OPS Doc 8168-OPS/611 Volume II
If required, exceptions or waivers to PANS-OPS criteria can be documented and coordinated with the appropriate authorities

FMS CodingFMS Coding
Interpretation by various FMCS’s Ensure that our intent is clear An extract of the Terminal Area Procedure
(SID/STAR and APPROACH) is coded in the form of the waypoint and path and terminator leg types as would be found in the full ARINC 424 database coding compatible with the data requirements of client FMCS

TrainingTraining
Workshops:– Tactical by design.– Last from two to six weeks dependent on the desired
end level of expertise.– Cover the complete procedure development training
for the front line working level of the air navigation service provider.
– Introduction to GNSS, PANS-OPS criteria, GNSS specific criteria, and approach design workshops.
– Aim is to introduce the participant to GNSS procedures and create a level of understanding to allow for review, approval and potential maintenance of GNSS procedures.
