The first U.S. Navy aircraft carrier, Langley was converted from a collier. She had low speed and was used as an experimental ship for testing various technical innovations as well as for training navy pilots.

Controls

Ship controls
VTOL: Throttle forward/backward
Yaw: Steer port/starboard
Deactivate 8: Scuttle ship (don't)

Aircraft controls
1 = Attack aircraft
2 = Bomber
3 = Torpedo Bomber
Activate 1/2/3: Release brake, turn on engine, activate flight controls & armaments for respective squadron

Flight deck instructions:

The deck is divided into 4 sections
(!) DON'T roll planes during deck operations!

Take off
1. Get some headwind full throttle ship to max speed.
2. Activate the squadron in front, 100% throttle then quickly deactivate to brake.
3. Wait for the engine to power up then release brake to launch.
4. To launch the next squadron, repeat step 1.

Landing
1. Ship at max speed.
2. Make sure the red zone is clear. If there's aircraft on red zone, taxii 1by1 and park on green & yellow zone.
(i) The planes have positive lift so you can deactivate controls in mid air but left it at full throttle.
3. Slowly approach the carrier.
4. Fly slowly in straight line enter to the center of green square.
(i) Every squadron has different speed and i don't know exactly how slow. A bit above stall speed about 5% throttle. Just feel it! feel the plane, become the plane.
5. quickly 0% throttle when the first aircraft passed the green square.
(i) Accident may happen but it's possible to land & it's pretty easy.

Credits

This is the first build i post with many components i learned from the SP community.

• Huge thanks to @MikeWallace for the 200iq invention of invisible rail-hanger assisted take-off/landing whatever the name & the squadron flight. I really stealin it hope you're okay with that yes?
• @232287168147825 for the auto aiming rotator.
• @typeZERO for proximity flak gun.
• @hpgbproductions for logic gates tutorial.
• @Searay for guide to fix the common Center of Mass/Lift/Thrust balancing error.
• @Walvis for upload with custom screenshot.
• @SimonGlaser for add image to post.
• @Skua for post text formatting.
• To SP community and to anyone who downloaded it. If you like it give upvote or if you don't just wait for my future builds.
• World of Warships for reference.

Additional notes

• If you don't want to see the shadow thingy, set the shadow graphics to medium or off
• The parts count got so high because it carry biplanes and that means more wings, more parts, more control surface.
• You can save a little bit parts by removing the plane in the hangar. Under these planes there's a small block that connects the plane with the hangar, delete that to remove plane.
• I already tested it's also possible to take-off landing manually without the assist system by deleting the invisible glass above the ship. As a biplane you have double lift which means shorter take off and easier brake because you're in a squadron. More wheels more brake.
• The real F3F Gulfhawk has retractable gear but in this build the maintenance team did some error and all the gear got jammed.
• I recommend to fire rockets in a salvo.

Update: I found the fix for flak gun stormtrooper accuracy! I moved the cockpit to middle and it obliterated any innocent AI planes passing by.
