Experience has shown that Large Lateral Deviations and Large Longitudinal Errors have had significant influence on the outcome of safety assessments before and after implementation of PBN-based separation in a portion of airspace. Each ANSP will need to establish the means to detect and report the occurrence of large horizontal-plane deviations.
The surveillance information available to ATC units provides the basis for identifying large horizontal plane deviations. A programme for identifying large horizontal-plane deviations should be established and ATC units should report such events monthly.
One of the principal duty of an EMA is to ensure the existence of a programme to collect this information, assess the occurrences and initiate remedial action to correct systemic problems.
BOBASMA will provide monitoring services for the international oceanic airspace of the FIT-BOB member States, where implementation of ADS/CPDLC technologies is undertaken to enhance surveillance and communications capability, leading to significant benefits for operational efficiency and regularity of flights.
The Flight Information Regions for which BOBASMA will be providing EMA services are
- Chennai
- Mumbai
- Kolkata
- Delhi
- Dhaka
- Yangon
- Colombo
- Male
- Lahore
- Karachi
- Kabul
