Description
Modern aircraft design permits very high rates of climb or descent. High climb rates are desirable for noise abatement purposes. High climb and descent rates allow a more flexible use of airspace.
Effects
A high rate of climb or descent can trigger operationally unecessarry "nuisance" Airborne Collision Avoidance System (ACAS) RAs.
A high rate of descent during an approach to land
Defences
Well designed Standard Operating Procedures (SOPs) should prevent avoidable interruptions and distractions, for example, the sterile cockpit procedure employed by many airlines reduces distractions and interruptions during high-workload situations.
Contributory Factors
- Equipment malfunction or failure.
- Poor TRM (TRM);
- Inadequate Standard Operating Procedures (SOPs).
Solutions
- Review and if necessary improve Standard Operating Procedures (SOPs);
- Insist that SOPs are followed.
- Review and if necessary improve the design of the ATCO’s position;
- Review and if necessary improve Crew Resource Management and Team Resource Management (TRM) training provisions.
