If you are flying a high-performance jet where precision at Mach speeds is critical, a redundant vane-based system is the industry standard. However, for those flying light piston or turboprop aircraft who want a reliable, low-maintenance safety tool to prevent stalls and loss-of-control accidents, a pressure-ratio system is usually the more practical and cost-effective choice.
Advanced pressure-ratio systems have the ability to sense blocked ports and produce appropriate cockpit warnings. Historically, fatal accidents resulting from relying on false indications from damaged vane-based systems have even forced some manufacturers of those systems out of business.
