Just because some business aircraft meet the technical specifications of Level 4 Automation guidelines doesn’t necessarily mean all the flight crews operating these sophisticated systems completely understand the procedures they’re asking the computers to fly.
Some Pilots Still Find “Climb Via” Procedures Confusing
Key Takeaways:
- Pilots are frequently misunderstanding and failing to comply with "Climb Via" RNAV departure procedures, particularly altitude restrictions, leading to a significant increase in pilot deviations at airports like Teterboro (TEB) and Henderson Executive (HND).
- These deviations stem from pilots misinterpreting clearance altitudes or not correctly programming sophisticated automation for published restrictions, and are partly due to procedures designed for high-level automation being used with aircraft requiring more pilot input.
- Continued non-compliance poses serious collision risks and threatens the cancellation of existing Performance Based Navigation (PBN) procedures and hinders the development of new ones, necessitating greater pilot diligence in reviewing SIDs and correctly using aircraft automation.
