The Plate shown is for the VOR+DME Instrument Approach to Rwy 27 at LGIR.
Any time on that Approach (even once visual) then, unless otherwise instructed by ATC, the published Missed Approach Procedure should be flown - which is straight ahead to the VOR then a Right Turn to Track 085 in Order to intercept the 040 Radial.
A Visual Circle to Land is allowed of this Approach.
However once a Circle to Land is started you are no longer on the published Instrument Approach so the published Missed Approach Procedure does not apply and if Visual references are lost it is, indeed, up to you what you do.
Using a Moving Map GPS would be too easy and my suggestions, in my previous Post, are based on the possibility of an aircraft fitted only with a VOR and a DME being allowed to fly this Approach.
