Narrative:

Cenrap operation this morning. It will be that way for several hours today. The presentation is incredibly poor. Examples: air carrier X a heavy B747 departure from lck is not shown on the radar until aircraft reaches 8000 ft MSL. A baron departure off osu airport is not displayed until reaching 4500 ft MSL, 5 NM southwest of osu. Air carrier Z a jet departure off cmh disappears between 4000 ft and 7000 ft MSL. The list will go on and on. This is only during first hour on position.

Title: TRACON CTLR COMPLAINT ABOUT THE RADAR COVERAGE THAT THE CENRAP PROVIDES WHILE THE TRACON RADAR IS OTS.

Narrative: CENRAP OP THIS MORNING. IT WILL BE THAT WAY FOR SEVERAL HRS TODAY. THE PRESENTATION IS INCREDIBLY POOR. EXAMPLES: ACR X A HVY B747 DEP FROM LCK IS NOT SHOWN ON THE RADAR UNTIL ACFT REACHES 8000 FT MSL. A BARON DEP OFF OSU ARPT IS NOT DISPLAYED UNTIL REACHING 4500 FT MSL, 5 NM SW OF OSU. ACR Z A JET DEP OFF CMH DISAPPEARS BTWN 4000 FT AND 7000 FT MSL. THE LIST WILL GO ON AND ON. THIS IS ONLY DURING FIRST HR ON POS.
