Final answer:
Obstacle clearance minimums for Night VFR in a Non-Mountainous Region in a 705 Operation are usually 1,000 feet above the highest obstacle within five nautical miles from the track, as set by Canadian Aviation Regulations for commercial airline operations.
Step-by-step explanation:
The obstacle clearance minimums for Night VFR in a Non-Mountainous Region in a 705 Operation require heightened vigilance to ensure safety during night flights. In non-mountainous areas, under Canadian Aviation Regulations (CARs) for commercial operators conducting a 705 operation (airline operation), the minimum obstacle clearance would typically be 1,000 feet above the highest obstacle within a horizontal radius of five nautical miles from the track. It is important to note that specific regulations may vary by jurisdiction and are subject to change. Therefore, always consulting current aviation regulation documents or a flight operations manual is paramount when determining the specific minimums for your operation.
