However, any aircraft operating under VFR must have the required equipment on board, as described in FAR Part 91. 205 ( which includes instruments necessary for IFR flight ); but the view outside of the aircraft is the primary source for keeping the aircraft straight and level ( orientation ), flying where you intended to fly ( navigation ), and for not hitting anything ( separation ).

However, there are still minimum weather conditions that must be present in order for the aircraft to take off and land ; these will vary according to the kind of operation, the type of navigation aids available, the location and height of terrain and obstructions in the vicinity of the airport, equipment on the aircraft, and the qualifications of the crew.
