Unless your really streching the neck with the face against the glass, only the tips of the wings can be seen from normal seated position.
Good in theory re the flaps but the lights policy as stated above is purely increasing visibility to aid in the 'see and avoid' mentality.
Unfortunately as the light procedure is published as an opertaing policy there is very little leeway to vary from its form. Just because it is current policy dreamed up as 'worlds best practice' doesnt necessarily mean it is the best procedure for all circumstances. Whether it is a benefit or more of a distraction to other operators will only be known through feedback. My suggestion should anyone be impeded or distracted by the lights that QF use- put pen to paper in a safety report.
