What next
Well, what seems to challenged is the syllabus itself. Where does the line get drawn?
What element of the syllabus should be included before solo and what left to later. Setting VORs to a QDM is one thing but tracking a radial while remaining spacially aware is another, how much then of ex18 is covered. The outside world can be a strange and unnerving place for a low hour student and i'm not convinced by timzsta and Rickford. How, as whopity has referred, can a student who has not been taught, fully, glide approaches as a technique undertake a forced landing off field with all the other factors to be considered, also.
Should a student be forced to divert when at the circuit solo stage then I would suggest that D&D on 121.50 for their expert assistance would be the safer bet.
