What differentiates a precision approach from a non-precision approach in the CRJ 200?

A precision approach in the CRJ 200 is defined by the provision of both lateral and vertical guidance to the pilot, which is typically facilitated through an Instrument Landing System (ILS). This system creates a glide path angle that allows the aircraft to descend toward the runway with a specific slope. This precise control over the aircraft's descent path distinguishes a precision approach from a non-precision approach, where pilots do not receive vertical guidance but may only rely on lateral guidance provided by other navigation aids, such as VOR or NDB.

In a non-precision approach, while pilots might still manage a safe descent, they do not have the same level of guidance for angles and glide slopes, leading to the need for more manual assessment of altitude during the approach. The glide path angle is crucial in precision approaches, as it helps in reducing decision-making workload during landing phases and enhances safety by establishing a standard descent path.
