Aviation SMS – Safety Performance Indicators (SPI) & Acceptable Level of Safety (ALOS) Executive Review – 1 Day


Aviation is an incredibly complex business environment. Demands placed on the organization and individuals to deliver are often considerable and place a burden on key individuals.

On a daily basis, Operators and Managers make decisions in real-time, weighing the probability and severity of any adverse consequences implied by the risk against the expected gain of taking the risk. (This process is known as risk management.” – ICAO)

We accept that absolute safety is generally an unachievable and very expensive goal, therefore the concept of acceptable safety has been adopted in aviation. The term “acceptable risk” describes an event with a probability of occurrence and consequences acceptable to the society

Managing Risks in Aviation

“The risks and costs in commercial aviation necessitate a rational process for decision-making.”

The term Acceptable Level of Safety (ALoS) defines an aviation service provider’s minimum level of acceptable risk for a given safety issue. “Acceptable” describes the need for no further mitigatory actions on the part of the service provider for the safety concern in question.

Safety performance indicators (SPIs) should meet quality criteria to assure they are quantifiable, representative of safety performance, comprehendible, and can be cost-efficiently used. Developed safety performance indicators should be related to the main operational safety issues.

“You cannot manage what you cannot measure”

The concept of an acceptable level of safety is expressed by two specific metrics, namely safety performance targets and safety performance indicators.

This course provides a detailed understanding of ALOS and how we can use SPIs to measure and manage our exposure.
