Safety Significance and Implementation of Alphanumeric Call Signs

The possibility of miscommunication in aviation due to call sign confusion is real.

One contributing cause to call sign confusion is the use of commercial flight numbers as call signs. There is a tendency for commercial flight numbers to be allocated consecutively with similar numbers, leading to similar sounding call signs. Instructions from air traffic control intended for one aircraft on heading, altitude, taxiing, runway entry and other clearances, or radio frequency changes, may be mistaken by another aircraft. This can lead to loss of separation between aircraft or runway incursion. There is also increased workload for pilots and air traffic controllers.
