What is the primary means of navigation indicated in the cockpit?

The primary means of navigation indicated in the cockpit of an aircraft like the CRJ550 is long-range navigation. This method utilizes advanced systems that provide accurate positioning data over considerable distances, which is crucial for commercial flight operations. Long-range navigation typically encompasses the use of technologies such as satellite navigation (like GPS), inertial navigation systems, and other forms of navigation aids that can help pilots determine their position and trajectory over long distances, ensuring they remain on course during various phases of flight.

While short-range navigation might be applicable during certain phases of flight, such as approach and landing, the primary navigation systems designed for the aircraft's operation focus on long-range capabilities to ensure efficiency and safety. Visual navigation, which relies on the pilot's observation of landmarks or geographic features, is less reliable for consistent navigation, especially at cruising altitudes where visibility may be compromised. Radio navigation, though important, typically supports long-range navigation rather than serving as the primary means by which the aircraft navigates over extended distances. This understanding highlights the central role of long-range navigation systems in modern aviation.
