No contest re VL, but:-
The book/s needs to explain what pilots (VFR and IFR) and ATC are
required/expected to do/provide in Class E (V+), and how CAR100 applies [in practice] to VFR and ATC in Class E (V+). Is my point
No book/s [including the actual application and/or operation of CAR100] says that does it!
