HMD has less accuracy than HUD when it comes to the unguided weapon.(a) True(b) FalseI have been asked this question in an online interview.This key question is from Helmet Mounted Displays in section Displays and Man-Machine Interaction of Avionics

Answer»

Correct option is (a) True

The explanation is: Dealing with guided weapons system such as missiles and laser-guided BOMBS the ACCURACY of HMD is adequate enough but for unguided weapons such as guns, unguided bombs, and rockets the accuracy is not yet feasible since the HMD is constantly moving with the pilots head. CURRENTLY, the boresight angles for HMD are 8 to 10 MRAD, whereas for HUD it is 1.5 to 2 mRad.
