DR Navigation
Hello,
The AIP states that a VFR flight may use the IFR techniques (Navaids, GPS etc) if the pilot is rated to use them, for navigation, as well as the map reading techniques. However there is no mention of use of dead reckoning here which is what I am currently using during my night VFR rating. What are the position fixing requirements for this? Is this a permitted navigation technique at night when I have no reference to the ground?
