[게임 설명]
The IAR-80 was a Romanian low-wing monoplane originally designed in the late 1930s by Industria Aeronautică Română (IAR, or Romanian Aeronautic Industry in English). First flown in 1939, the IAR-80 was comparable to other fighter aircraft designs of the late 1930s and would remain in service with the Royal Romanian Air Force throughout World War II until the end of the war in May 1945.
The armament of the IAR-80 initially consisted of Belgian-made Fabrique Nationale FN 7.92 mm light machine guns, which were a licensed version of the Browning M1919 machine gun. These machine guns would eventually be replaced by 13.2 mm FN heavy machine guns and German 20 mm MG FF/M and MG 151/20 cannons. In 1941, the IAR-80 was modified to become a dive bomber and thus became the IAR-81. This new model was fitted with a bomb cradle under the fuselage which would throw the bomb clear of the propeller when the bomb was released.
The first production IAR 80s were completed in January 1941, and they were in action against the Soviets from the first day of Operation Barbarossa on June 22,1941. IAR-80s and 81s both saw action during the Battle of Stalingrad and later took part in combat over the Kuban and the Crimea throughout 1943 and into 1944. Meanwhile, in August 1943 IAR-80s took part in the defense of the Romanian oil fields at Ploesti for the first time against US Army Air Force B-24 heavy bombers.
Further defensive missions would be flown over Romania through the summer of 1944 against American heavy bomber raids. After Romania switched sides in August 1944 and joined the Allies, IAR-80s and IAR-81s fought alongside the Soviets until the war ended in May 1945.
In addition to Quick Mission Builder, Advanced Quick Mission Generator and Multiplayer modes, you can fly it in Career mode during Battle of Stalingrad (Grp. 6 BoPi ARR and Grp. 8 Vânătoare ARR) and Battle of Kuban (I.A.R. 80-A in Grp. 3 Vânătoare ARR and I.A.R. 80-B in Grp. 4 Vânătoare ARR).

Operation features
- The aircraft has no constant propeller governor. The propeller speed is controlled by manually changing the propeller pitch using a switch on the instrument board (default propeller pitch commands in the sim are [RShift + +/-]).
- Due to the absence of a constant propeller speed governor, it is necessary to carefully monitor the propeller RPM, especially in a dive - due to the spinning up of the propeller during acceleration, it is possible to exceed the maximum RPM and cause an engine failure.
- The aircraft has no cylinder head temperature gauge - only an oil temperature gauge.
- The oil radiator has no regulation (there is a second adjustable oil radiator on I.A.R. 80-M, 80-C and 81-C modifications).
- The aircraft is equipped with elevator trimmer.
- Mixture control is automated, the automatic regulator maintains the set mixture composition and automatically enriches the mixture at low and full throttle. The optimum mixture is set by the center position of the control lever.
- The flaps are hydraulic and can be set to any angle up to 60°. In the dive bomber version, the fully released flaps are used as air brake. There is no flap position indicator.
- The aircraft has differential pneumatic wheel brakes with shared control lever. This means that if the brake lever is held and the rudder pedal the opposite wheel brake is gradually released causing the plane to swing to one side or the other.
- The aircraft has a hydrostatic fuel gauge which shows total fuel remaining only when manual sucker lever is pushed in. In the sim, hold [RShift+I by default].
- To drop bombs, you must switch on the bomb release system first [N key]. After dropping bombs, the system should be manually deactivated.
- When the bomb release system is switched on, the flaps are automatically fully released as an air brake and retract automatically either when the bomb release button is pressed or when the system is switched off.
- The bomb release system can either drop only the central bomb or all three bombs at once.
- The gunsight is adjustable: both the target distance and target base can be set.
- In the dive bomber version, the tilt of the gunsight is adjustable [RAlt + F by default].
- The gunsight has a sliding sun-filter [LAlt + F by default].
