I'm stunned by some of the ignorance and waffle posted by some people. A visual run in and break is the quickest, most fuel efficient and safest means to recover a fourship to any airfield with minimum disruption to the rest of the circuit. If its busy just bring the speed back to sequence with all circuit traffic. Go as low as is allowed to skyline all the other circuit players and aid tally. Just for the civilian peace of mind we will not break a four ship into the circuit so it comes into confliction with other players, its not a cowboy manvre. Slow trainer aircraft and large numbers of fast jets, don't mix so most Military bases will establish a light aircraft hold to provide deconfliction and allow the FJ to land, a go-around will cost me approx 150kgs of fuel compared to the couple of litres that a Grob uses!! Having said all of the above there is no better way announcing your arrival than as a tight echelon 4 ship at 500 kts+ coming over the runway threshold followed by a 1/2 sec fan break.
Sorry, forgot the most important part of the debate. a VRIAB is the standard means of joining the visual pattern at every NATO base unless promulgated otherwise.
