What is the difference between IFR and VFR?
Visual Flight Rules or VFR is when a pilot is able to operate and navigate an aircraft via visual references. The horizon is used for pitch attitude as well as bank angle in VFR flight, as well as ground obstacles such as towns or rivers for navigation. Under IFR, or Instrument Flight Rules, we are unable to view ground references or the horizon and we must fly the aircraft based solely on our instruments.
