What is the base altitude for low-level airways?

The base altitude for low-level airways is 2200 feet AGL. This altitude designation is critical for pilots as it helps in establishing the vertical limits for flights within these airway structures. Low-level airways are specifically designed to assist aircraft that operate at lower altitudes, typically under 24,000 feet, and provide a controlled environment for navigation and communication in congested airspace.

This specific altitude of 2200 feet AGL ensures that the airspace is above most terrain and obstacles while maintaining sufficient clearance for safe navigation. It creates a buffer for aircraft transiting through lower-level airspaces, enhancing overall flight safety. Knowing this altitude is essential for pilots during planning and maintaining situational awareness to avoid terrain and comply with airspace regulations. Understanding the base altitude is part of the foundational knowledge necessary for operating safely and legally within Canada’s airspace system.
