EASA SIB 2024-14
Conduct of Accuracy Tests for Type B Electronic Flight Bag Application for Aircraft Performance or Mass and Balance Computations
Summary
EASA Safety Information Bulletin 2024-14 provides guidance on conducting accuracy tests for Type B Electronic Flight Bag (EFB) applications used for aircraft performance or mass and balance computations. It applies to operators of commercial air transport and non-commercial complex aircraft, including Airbus, Boeing, and Embraer types. The bulletin emphasizes verifying that EFB calculations align with data from the aircraft flight manual or certified software tools.
What Changed
This new bulletin introduces recommendations for operators to perform thorough accuracy tests on their Type B EFB applications, especially when paper aircraft flight manuals are replaced by computerized certified software. It clarifies the appropriate certified software tools to use for Airbus, Boeing, and Embraer aircraft and highlights the need for representative condition testing across the aircraft's operating envelope.
Why It Matters
Accurate performance and mass and balance data are critical for safe flight operations. Inadequate testing of EFB applications can lead to incorrect data being used, posing safety risks. This bulletin helps operators and competent authorities ensure that EFB tools provide reliable calculations, supporting regulatory compliance and operational safety.
What To Do
Operators should verify that all required accuracy tests for their Type B EFB applications are fully completed using either paper charts or certified software tools as applicable. They must evaluate any discrepancies found and apply temporary mitigation measures until resolved. Competent authorities should consider these recommendations during EFB approval and oversight activities. No specific compliance deadlines are stated.
