Which flight condition does VFR primarily concern itself with?

VFR, which stands for Visual Flight Rules, primarily concerns itself with utilizing visual references for navigation. Under VFR, a pilot is responsible for seeing and avoiding other aircraft and obstacles, and for navigating by visual landmarks rather than relying on instruments. This enables pilots to fly mainly in conditions where they can maintain visual contact with the ground and other navigational references, facilitating a safer and more direct form of navigation.

Night flying, while it can be conducted under VFR, falls under a different set of considerations, as pilots must have the appropriate training and equipment to safely navigate and avoid obstacles in the dark. Flying in instrument conditions typically requires adherence to Instrument Flight Rules (IFR), where navigation is done using instruments due to reduced visibility and it doesn't align with VFR principles. Helicopter operations can also be conducted under VFR; however, VFR itself is not specifically focused on helicopter operations but rather on the principles of visual navigation applicable to all types of aircraft.
