I have made over 1000 receiver contacts with Valiant,Victor1 and 2, Vulcan, VC10, Nimrod and Herc I have tanked behind Valiant, Victor 1 and 2, Vulcan, VC10, Tristar and Herc. I must have watched thousands of receiver contacts and I reckon the most successful technique, as described by those who know, is to settle down around 5 feet behind the drogue, check settings including trim,attempt to settle heart rate (especially if AOC is sitting next to you).Now, looking up the line of the hose and applying any offset for the bow wave, increase power to give a smooth approach of 3 to 5kts on the tanker and without look at the drogue, maintain the hose line. This does not ensure success but increases your chances greatly, There will be days when that drogue looks 10 ft wide and you can not miss and there will be days when it looks 2 lnches and you certainly can.
