No-arrival sectors

What is it with arbitrary rules and aviation? Like how some security Ph.D. determined that a quart bag of three-ounce containers dont constitute a security threat but a single quart of Pepsi does. Maybe they think terrorists arent smart enough to pool their resources. Or maybe the TSA brass just has something against soft drinks.

Key Takeaways:

The article critiques seemingly arbitrary and complex aviation rules, drawing parallels between TSA liquid restrictions and nuances in instrument approach design.
It explains that "Procedure Not Approved" (NA) sectors on instrument approaches, such as Aiken's VOR/DME-A, are based on TERPS standards for turn requirements from specific airways that lack a charted procedure turn.
Inconsistencies persist as older approaches, like Marion's VOR/DME-A, lack these modern NA restrictions because updates are not prioritized as safety-critical, suggesting the rules can be more procedural than hazard-driven.
