SRPs vs SPIs - What's the Difference?

The SPI is a data-based parameter used for monitoring and assessing safety performance. Working along with a Safety Performance Target (SPT) it creates a planned or intended objective for safety performance over a given period. This reduces complexity to small number of key indicators and should be associated with mitigating your overall risk to its lowest level. The development and tracking of SPIs can be created to support the mitigation of the SRP. By evaluating the proposed mitigation of risk, we can create SPIs that may be associated with the operations and project targets for evaluation. SPIs will also create awareness among the personnel.

• Stabilized approaches
• Landing in Touch Down Zone
• Procedural Errors or Lapses – Climb & Decent Via, FMS programming errors
• Aircraft not grounded for fueling or no wing walker during towing
• Incorrect fuel loads
• Working Fatigue
• Shift Differential or Circadian Low Operations

Tracking the SPI trends can identify changes in the safety performance when expressed by the SPIs and their associated alerts and target values. Changes can be addressed quickly when needed to enhance safety. Targets should be realistic and achievable with consideration given to recent historical performance for a given indicator. SPIs should be appropriate and pertinent to the individual organization, not industry standards.

Reflection needs to be given to what our safety issues are and how to monitor and address them. By utilizing the Safety Risk Profile, we can identify and assess the overall risk associated with the operation and create the mitigation to achieve the lowest level. The collection of data from the Safety Performance Indicators and Targets collectively aids in mitigating the risk to the lowest level.
