can any body tell that how F-16B or any other twin seater fighter is more beneficial than single seater...plz.
Although B model has somewhat less fuel than A model and it evidently affects its deep strike capability, the two seater is beneficial in close air combat or dogfights.
Its said that two pairs of eyes are better than a single pair of eyes.
In a dogfight, the role of ground radar is not more important than pilot himself. The ground radar may be helpful while executing an interception geometry or going in for the dogfight. Once dogfight starts, pilot mostly relies on his own sensors, his own eyes and his aircraft instruments.
To give an example, Sqn Ldr Khalid Mahmood lost an opportunity to become ace due a false alarm of the ground radar. Ground radar ordered him to break , and thus he lost the opportunity to do more shooting. This was during Afghan war of Soviet Occupation.
Khalid could have seen any lock on his Radar Warning Receiver. He should have neglected the false alarm and should have relied on his own sensors.
The presence of a second pilot or Weapons Systems Officer (WSO) or Radar Intercept Officer (RIO) shall ameliorate this situation. Instead of depending on ground radar or even AEW aircraft, second member shall focus on threats on his Radar Warning Receiver, shall employ jammer when required, can control the release of chaff/flares/towed decoys etc.
Also the fighters have multi-functional displays ie a single display can be used for navigation, stores management (weapons), engine and fuel situation, tactical situation displays etc but only one at a time.
The presence of second crew has also the advantage that if pilot is keeping an eye on navigation display and following the waypoints, the second member can monitor the radar picture ....
Mirages and Sabres have been doing strike missions cross the border and they were single seaters. More advantage of F-16B seems in dogfights, but they can also help in interdiction strikes.
