... if a missile launched in UPR, and the target descends, than the system will guide the missile as T/T.
What could be the purpose of such sort of behaviour?
Lazy FCO behavior.
I am sorry, but don't understand...
These systems were exported to countries, where the level of knowledge of the FCO's were not high.
If a plane does a dive towards the ground, and the missile is guided with UPR (FCO forgot to switch it into K when H<5 lamp illuminates), than the system switches to T/T.
Why T/T instead of K?
Because the diverting plane might use jamming, and in this case T/T is the best method.
