CAVOK and, I assume, daylight?

Lowest Safe Altitude doesnt apply in Day VFR. You can see and avoid the planet, so, see and avoid the planet.

The UK Manual of Air Traffic Services (Cap 493) states in Section 1 Chapter 3:
5.5 VMC Climb and Descent
To avoid excessive delays to traffic when radar is not available, controllers may
authorise an aircraft to climb or descend in VMC provided:
a) essential traffic information is given;
b) the pilot of the aircraft climbing or descending agrees to maintain his own
separation from other aircraft;
c) it is during the hours of daylight;
d) the aircraft is flying in visual meteorological conditions;
e) the manoeuvre is restricted to Class D, E, F and G airspace at or below FL 100; and
f) the aircraft is not in CAS-T.
You can find the Cap 493 at www.caa.co.uk. Click on Publications, then Search for a CAA Publication, then Air Traffic Services.:)

Obviously only works in the UK .....
