What do visual flight rules (VFR) require in terms of specific instruments?

Visual Flight Rules (VFR) stipulate that pilots must have basic instruments available in the aircraft to ensure safe navigation. This includes instruments that assist in maintaining control of the aircraft and awareness of the environment. Specifically, the requirements focus on essential instruments like the altimeter, airspeed indicator, magnetic compass, and attitude indicator, which are vital for visual navigation and situational awareness.

Having basic flight instruments ensures that pilots can make informed decisions based on their altitude, speed, and direction, while also allowing them to maintain visual reference to the terrain and other aircraft. While advanced navigation systems can enhance flight safety and efficiency, they are not mandated under VFR regulations for a pilot to operate under these rules. Thus, option B accurately reflects the requirement for basic flight instruments necessary for VFR navigation.
