Bookworm: Let's for the sake of argument say that our clearance was 3200' direct BN for later visual approach. 5 miles from the beacon the controller has not yet recieved our "Field in sight". Instead he issues a clearance for the ILS 22. We then request "maneuver space" in order to position ourselves for a direct approach well outside BN and also well outside the ILS GS intercept point.
I would then say that since we are cleared for the ILS, that would imply that as soon you are established on the LLZ you may descend to 3000' (Initial approach altitude) and perform a straight in ILS 22, if your position after establishment can be confirmed either by other navaids or by ATC radar.
How can this be illegal ?
Pedantic or not. I would like to hear every aspect of the case..
