The PPI and A scope display two different radars. PPI is for the SJ Surface Search Radar while the A Scope is the SD Air Search Radar. The A Scope radar is omnidirectional, meaning it transmits and receives 360 degrees. Because of that you can only get range information off of the radar and not bearing.
