For the Attention of Safety Management at IATA Member Airlines

Dear Colleagues,
I am very happy to announce the publication of the third edition of Unstable Approaches: Risk Mitigation Policies, Procedures and Best Practices. Like its predecessor, this edition has been collaboratively written by IATA, CANSO, IFATCA and IFALPA to address the challenges surrounding unstable approaches, a major contributor to accidents.

Despite improvements in the safety of operations, there remains a risk of an approach and landing accident, including hard landing, runway excursion, and other accident categories. A stable approach means that the aircraft will arrive at the runway in the correct configuration, at the correct speed and power setting, as well as on the correct lateral and vertical path. An
unstable approach is where one or more of these parameters is incorrect, and as a result carries an increased risk of an approach and landing incident and/or accident. In addition, an approach which is stable for the final 1,000 feet of the approach affords the pilots the time to fulfil their flying and monitoring duties, maintain situational awareness and preserve resources and mental capacity for any other unexpected factors that may occur during this critical phase of flight. Continuous improvements to stable approach criteria and policy compliance, including the discontinuation of an unstable approach, will reduce the risk of such an accident.

The industry – manufacturers, regulators, professional associations, air navigation service providers, operators, air traffic controllers and pilots – share an unequivocal position that the only acceptable approach is a stabilized one. Professional pilots pride in achieving it on every occasion. Recognized industry practice is to recommend that a failure by the pilot to achieve a stabilized approach must result in a go-around, which is an essential safety maneuver for all flight crew. In this case the pilot executing the go-around is considered to have demonstrated good situational awareness, decision making and professionalism.

I wish to acknowledge the efforts and input of our invaluable partners– CANSO, IFATCA, IFALPA, Manufactures, and the Safety Group Members and Observers–in producing the third edition of this important reference document.

With thanks and best regards,

Gilberto López Meyer
