Whilst this Manual did explicitly prohibit manoeuvres which were contradictory to the guidance provided by a TCAS RA, it was found to also state thatATC measures are the main and major condition of collision avoidanceand went on to state that the most important actions for the avoidance of in-flight collisions werethe visual control of the situation in the airspace by the crew and the correct execution of all instructions issued by ATCwith the following reference to TCAS stating merely that itis an additional instrument which ensures the timely determination of oncoming traffic, the classification of the risk and, if necessary, planning of an advice for a vertical avoidance manoeuvre.
