The UK Air Accidents Investigation Branch has called for regulators to develop safeguards to prevent take-off performance miscalculations. The AAIB argues that they happen too often and the potential consequences are serious.

It recommends to the European Aviation Safety Agency that it should provide specifications for a take-off performance monitoring system (TOPMS) and require it to be fitted to airliners.
