SRPs vs SPIs - What's the Difference?

Do you know what the differences between a Safety Risk Profile (SRP)  and Safety Performance Indicators (SPIs)? Baldwin Aviation has partnered with World Fuel Services to answer that question.

The SRP is an evaluation of the perceived highest risk associated to the overall operation of the organization, whether it is a Flight Department, Management Company, Fixed Base Operator (FBO) or Maintenance Facility.

The SPIs are created to monitor the individual safety parameters and mitigated to their lowest value of risk which collectively will reduce the overall operational risk. The SRP is what is being asked of the organization, the level of risk associated with the operation and the how to mitigate the risk to the lowest level.

Through ICAO Doc 9859, we can define the Safety Risk Management (SRM) and SRP as a document that is an overview of the safety-risks that are generally experienced by the flight operation and the development of mitigation strategies which are integrated into the operators’ system.

  • The overall level of safety management (e.g. low, medium, high) needed for consistent safe flight operations; and
  • The specific areas of higher risk that individual operations my experience.

Safety Risk Profile (SRP)

The SRP should be reviewed annually with a complete assessment every three years and/or any time there is a change in the operational risks. Operational changes may include but not restricted to:

  • Department management style or Principal/CEO travel requirements
  • New operational crew members, maintenance and line support staff
  • Company acquisition and/or blending of business operations
  • New fuel farm, fuel trucks or aircraft tow equipment
  • New aircraft, avionics suite, auto-throttles, HUD, EVS
  • Remote airport locations, mountainous terrain, minimal weather information
  • Oceanic and international operations

This example shows that your company has acquired a new international company and a larger aircraft has been purchased to accommodate the executive travel needs. Your department has now grown with additional flight and cabin crew for oceanic and international operations along with a different hangar facility and fuel farm. The associated risks with the new operation that need to be mitigated will be:

  • New aircraft and avionics, auto-throttles, HUD and EVS
  • Additional flight and cabin crew members
  • Oceanic and international operations
  • Hangar facility and fuel farm operations
  • The plan to mitigate the associated risk can include of the following:
    • Fuel farm training and certification along with facility operational procedures
    • Aircraft and avionics training along with HUD and EVS certification.
    • Higher crew minimums until knowledge and experience are gained
    • Job and duty description to clarify and enhance communications of operational staff
    • Simulator training for oceanic lofts, international STARS and SIDs and airport familiarization
    • Adding experienced international contract crew members if needed to gain knowledge

Safety Performance Indicators (SPIs)

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.
