While crossing the bay of Biscay I normally run surfaced for 1 hour while manning the guns (to protect against fighter attacks as there is no time to dive against them ,and submerge for 1 hour at ahead 1/3.I make a full surface on clear days,and run decks awash at night while recharging.When out to sea I risk a full surface run as only bombers can reach you then and are much slower as a result,and if you have a half decent watch crew and clear conditions,and good reactions,and not travelling with TC over 64,you should be able to get under just in time.Just remember to hammer those engines and level off at 50m,while making a full 90 deg turn port or starboard.Reduce speed after the first set of bombs land.Return to course,then get the men to work reparing your now f####d UBoat!

...unless of course you made it
This of course can only work in ideal conditions,and I have already lost 2 UBoats to air attacks (that was also with the stock game,or the Jurassic era).I reckon i'm going to have real fun this time
