Similar call signs for flights may cause safety issues

HCMC – The Civil Aviation Authority of Vietnam (CAAV) has requested local airlines to change commercial flight numbers for flights that sound similar to each other.

The CAAV has written to the Vietnam Air Traffic Management Corporation (VATM) and carriers including Vietnam Airlines, Vietjet Air, Bamboo Airways, Pacific and Vietravel Airlines, asking them to take measures to reduce confusion resulting from the similarity of call signs.

According to VATM, there are some flights that have similar commercial flight numbers when they are operating at the same time, in the same airspace and used by a particular flight operator.

For example, aircraft from different airlines may have identical call signs, such as HVN123 and BAV123, or flights from the same airlines carry similar air pairs, such as HVN7344 and HVN1344.

For safety reasons, local airlines are required to adjust seasonal flight schedules so that aircraft whose commercial flight numbers are nearly identical will not operate at the same time and in the same airspace.

Flight crews and air traffic controllers are requested to take caution while assuming their duties, ensuring a smooth communication between them to reduce possible safety issues.
