Pilots encounter significant human factors challenges and potential safety risks due to the lack of standardization in attitude indicator symbology (sky vs. ground pointers) across different aircraft.
The FAA has published new flight plan codes (e.g., for ADS-B emitter types) in the AIM that are currently unusable, as the systems that process flight plans are not yet updated to accept them, leading to confusion and rejected plans.
Aviation regulations contain specific nuances, such as TAFs extending to 30 hours for international airports and maximum holding altitudes established due to terrain clearance or airspeed considerations, while also cautioning against sole reliance on GPS given potential signal disruptions.
