Agrowing sense of alarm over the rising incidents of mid-air collisions and near misses, brought about the introduction of TCAS and today the sky is far safer to fly  in.  However, this also brought about an unwelcome and recurrent side effect that of nuisance or operationally undesired RA commands.
An operationally undesired RA is one that is triggered during 1000 ft level off manoeuvres, while the crew is operating within clearances granted. This normally occurs when the vertical closure rates are high. This accounts for almost 50 % of RAs encountered in today’s environment.
