I take your point about the National Requirements.
However the part of Cap 804 you quote states as follows:
3.1 4 Exercising the privileges on Microlight aeroplanes on the basis of an SEP(Land)
Class Rating
The holder of a UK issued licence or any Part-FCL licence with an SEP rating, may,
subject to differences training on the appropriate class with a suitably qualified
instructor, exercise the privileges of their licence on microlight aircraft. However, any
experience gained in microlight aircraft cannot be counted towards the flying experience
necessary to maintain the full SEP or TMG privileges.
The key phrase being:
...may,
subject to differences training on the appropriate class with a suitably qualified
instructor...
The wording here is similar to that found in ANO Article 62(6), and is where the problem lies.
This phrase could, as you suggest, imply a requirement for 'Differences Training' before flying
any Microlight Aircraft or, as Xrayalpha and I suggest, the need to complete any 'Differences Training' required if changing between control systems, as required at: 3.11.2
3.11.2 Microlight pilots wishing to convert between weightshift and 3-axis microlight control
systems, or to a microlight with more than one engine, shall undertake differences
training given by a flight instructor entitled to instruct on the microlight aeroplane on
which instruction is being given.
