Update 4.502

Attention Pilots!

On this chilly Autumn day, we’re releasing a large update to IL-2 Sturmovik - update 4.502 is here! The star of this update is the new Hurricane Mk.II Collector Plane. This plane has the most modifications in our sim and with a wide range of weapon loadouts available this makes it 5 aircraft in 1. You get several variants including the IIa, IIb, IIc, IId and the one with the Soviet armament. The famous Dust Filter and Merlin XX engine with +14lb boost are also available. On top of all that, you can use the new bird in the Career mode right away - we added it to the Battle of Moscow and the Battle of Stalingrad careers. In addition to the Hurricane, we have added the legendary С-47А "Skytrain" transport plane for the Battle of Normandy. The C-47 is AI only but adds a new dimension to our missions and the variety of Allied aircraft you will encounter in the sky. It is also great for mission makers who want to make supply runs an integral part of their battle. And finally, the Battle of Moscow players receive new 4K quality skins for the Bf-110 E-2 thanks to our talented friend Martin =ICDP= Catney.

On the technical front, we have added a new and more realistic G-load physiology modeling system. This work was described in great detail in our Developer Diary #263. Additionally, a lot of work was done on all the aspects of the ground battles, significantly improving the quality and realism of Tank Crew engagements. There are many improvements to the pilot AI as well in this update. And finally, long-awaited Career mode improvements are finally starting to arrive.

Main Features
1. The Hurricane Mk.II Collector Plane is now available to its owners;
2. The C-47A transport aircraft is now available in the sim as an AI enemy or ally in the Quick Mission mode. It can also be used in custom missions as an AI transport aircraft;
3. Female crews got female voices in the radio messages;
4. Pilot physiology modeling has been improved significantly. This is described in detail in the Developers Diary #263;
5. The zoom function now works correctly on VR devices with canted displays (Pimax) without using the performance-intensive Parallel Projection mode;
6. New multiplayer scenarios, including Cooperative ones, are added for Tank Crew (you can create a server directly from the game by selecting a scenario or scenarios from the Multiplayer\Cooperative\TankCrew or Multiplayer\Dogfight\TankCrew folders);
7. 4K external textures for Bf 110E heavy fighter (Battle of Moscow) are added thanks to Martin =ICDP= Catney;
8. A-20 and B-25 bombers got new paint schemes with invasion stripes for different timeframes;

10. Both tank campaigns are now available in Simplified Chinese, German and French;
11. KV-1s got an additional paint scheme;
12. It is now possible to use binoculars or personal weapons after pressing the "T" button (except for the M4A2 tank, where binoculars and personal weapons cannot be used simultaneously with a machine gun);
13. It is now possible to designate a waypoint on the ground in a command mode while using binoculars;
14. The enemy spawn point in Tank duel quick mission is correctly randomized after the destruction of a previous one if the player did not leave its spawn point;

17. Trying to fire the M4A2 machine gun while using binoculars or personal weapons won’t work;
18. AI gunners use bracketing the target with fire when engaging the ground targets both for the range and (if the target is moving or there is wind) the azimuth error. The size of the initial aiming error depends on the AI level, distance, target speed and wind;
19. Ground AI gunners now have a certain delay in detecting and starting aiming at a new target depending on the AI level, distance and density of the group of enemy targets;
20. Ground AI vehicles return the turret and/or gun to the traveling position only after a considerable time after the destruction or disappearance of the last enemy target from the field of view;
21. Fixed an issue where detailed AI tanks (and especially self-propelled guns) could not hit the target at minimum distances (they were firing above the target);
22. SU-152 will correctly stop for a shot and won’t drive towards the target without firing;
23. The extra (maximum) AI level parameter has been removed from the Quick Mission, it caused errors in the AI functioning;

45. incorrect (missing) armor value of the armored headrest has been fixed for P-38J;

Visual aircraft improvements
46. Yak-9 s. 2, Yak-9T s.2, Fw 190 D-9, P-47D-22, P-38J-25, P-51D-15: jettisoned cockpit canopy has all the details;
47. Fixes for Bf 109 G-6 4K textures from Martin = ICDP = Catney (Barkhorn and Hartman planes);

59. AI pilots attacking a ground target from a high altitude will reduce the altitude in a downward spiral first;
60. AI pilots now try to reduce the G-load they experience in order to prevent loss of consciousness if their condition is deteriorated due to fatigue or other factors;

Career mode improvements
61. An AI in Career mode won’t stuck at the first route waypoint after takeoff if its assigned target is very near (less than 5500 meters);
