Genuine question - at what point does a 'goonbag' become compulsory? Obviously I've seen forces aircraft operate over water without them (mainly Nimrod crews' publicity pictures or Prince William flying his SAR cab), but is there a percentage of flight over water that mandates their use? Or is it an aircraft captain/authoriser decision?
