[derstosstrupp]

Surfacing (from Periscope Depth)

C – Orders “Prepare to surface” (Commander makes ready to climb ladder, Navigator/Radioman to negative tank controls, Diving Officer/Helmsman at diving station)

C – Orders “Both Great Ahead” and “Surface!”

D/H – Sets fwd planes hard up, aft up 5 deg. When boat rises, reports “Boat rising” and orders “Flood negative”. Reports depth change: “14….13….12….”

N/R – Floods negative tank, makes ready to blow ballast. Notes current position on chart.

C – Orders “Blow” and climbs ladder to hatch.

N/R – Blows ballast, awaits order from commander to stop blowing, verifies negative flood valve shut.

D/H – Reports “Hatch coming free” when at 7.5 meters.

C – Climbs topside, orders “Switch to diesels”.

D/H – Switches to diesels and back to Great Ahead.

D/H – Reports “boat is out” when fully surfaced.

C – Orders “stop blowing” and quickly scans horizon to ensure all clear.

N/R – Stops blowing ballast, stands by. (This ensures that if not all clear, boat can get back down in a hurry)

C – If all clear, orders “Blow with diesel”. (This is a historical procedure not replicated in the game, but in WP it can serve as a signal to finish blowing as well as a reminder to start the diesel if not yet started)

N/R – Finishes blowing ballast, reports “All have blown” when done.

D/H – Asks Commander if bilge may be pumped. Starts compressor and, if ordered, bilge pump.

C – “Secure from diving stations” (All are already in correct positions except Navigator/Radioman who returns to tower), orders course and speed as desired.

D/H – Unless told by commander otherwise, sets telegraph to charge batteries.

D/H – Monitors compressed air level and stops compressor when done.
