Using The gbu32(1000lbs) bomb:
 While using the gbu32(1000lbs) bomb you should be
 flying low close to the ground target you have locked
 and also the throttle should be around 32 or 34
 i.e,you should be flying at a low speed otherwise the
 radar message "DROP" will never appear.However this is
 not the case with gbu32(2000lbs) bomb.

 Select campaign 4, mission 7. Take off, then change 
 your heading to 212 degrees. Arm the JDAM while flying 
 in that direction and repeatedly press [Tab] until a target 
 identified as Norman 1, 2, 3, or 4 is locked on. 
 Such a target is a cow, which can be bombed. 
 
 
 Hints: 
 ------- 
 Because the F-22 Raptor employs LOST (low observable 
 stealth technology), it's always a good idea to reduce 
 the RCS (radar cross section) of the aircraft as much 
 as possible. Most of the time, you should fly with 
 your radar turned off while maintaining a cruising 
 speed of around 400 to 500 mph (approximately 90 
 percent thrust). 
 
 Refrain from carrying ordnance on your aircraft's 
 external hardpoints. Weaponry mounted underneath 
 your wings will increase the RCS of the aircraft, 
 making it much easier for enemy radar installations 
 to track your aircraft. 
 
 Your wingman is particularly adept at taking out SAM 
 (surface-to-air missile) batteries. For that reason 
 alone, you should let your wingman concentrate on the 
 destruction of any SAM sites within the objective area
