Under which of the following can pilots be qualified to fly?

Pilots can be qualified to fly under Visual Flight Rules (VFR) and Instrument Flight Rules (IFR). VFR allows pilots to fly based on visual reference to the ground and other landmarks, which is typically in good weather conditions. However, pilots can hold a VFR qualification while also being trained and qualified under IFR, which is essential for flying in poor visibility or instrument conditions. This dual qualification enhances the safety and capability of a pilot, enabling them to operate in a broader range of weather conditions and air traffic scenarios.

The inclusion of both VFR and IFR qualifications reflects the comprehensive training that pilots undergo, allowing them to adapt to varying flight conditions and regulations as necessary. This versatility is crucial in ensuring safe and efficient flight operations, particularly in busy airspace.
