When is it determined that you have proper interval according to aircraft positioning?

The determination of having proper interval according to aircraft positioning occurs when both conditions A and B are met, and you have received clearance from the controller. Proper interval is critical in maintaining safe separation between aircraft during various phases of flight, particularly during takeoff and landing.

The phrase "conditions A and B are met" refers to specific criteria regarding the positioning of your aircraft relative to others in the vicinity, such as the distances or timing intervals established by air traffic control. Clearance from the controller is also essential, as it confirms that air traffic management has assessed the situation and permits you to proceed based on the established safety parameters.

Having proper interval ensures that the aircraft can operate safely without risk of collision, which is why the intersection of positional criteria and clearance is fundamental to the operational protocol of flight training and air traffic management.
