What to do

Operators using OPT for iOS should review Boeing's Multi Operator Message MOM-MOM-22-0075-01B and verify the software version on their electronic flight bags. They should implement Boeing's recommended corrective actions and upgrade to OPT version 4.72 to resolve the identified issues. No specific compliance deadline is stated, but prompt action is advised to ensure accurate performance calculations.

Summary

The Safety Alert for Operators SAFO 22002 addresses issues with Boeing's Onboard Performance Tool (OPT) version 4.70 for iOS devices, used on Boeing airplanes. The document highlights two calculation errors affecting takeoff and landing performance data, which could lead to incorrect runway length information being presented to flight crews. These issues specifically impact the accuracy of landing calculations and intersection takeoff calculations within the OPT software.

What changed

SAFO 22002 identifies two software errors in OPT v4.70 for iOS: one causing landing calculations to use takeoff runway parameters instead of landing runway data after viewing airport info, and another causing intersection takeoff calculations to incorrectly use full runway length after app relaunch. Boeing has released OPT version 4.72 to correct these issues.

Why it matters

Accurate takeoff and landing performance calculations are critical for flight safety and regulatory compliance. The errors in OPT v4.70 could result in flight crews receiving incorrect runway length data, potentially affecting operational decisions and safety margins. Operators must ensure their electronic flight bags provide reliable performance data to maintain safe flight operations.
