When radar is available it may, subject to workload, be used to provide navigational assistance to the pilot.
1.5.2.2 If no authorization to proceed is given by ATC the pilot should leave or avoid controlled airspace and areas of dense traffic, and either:

  1. Go to an area in which he can continue his flight in VMC, or

  2. Select a suitable area in which to descend through cloud, fly visually to a suitable aerodrome and land as soon as practicable.

Note: Before doing so, however, he should consult ATC who may be able to give him instructions or advice. He should also take into consideration the latest meteorological information and terrain clearance.
