sir and mam, i need your expertise regarding DME-42. We encountered a discrepancy on DME. DME negative distance. During the operation the IND-42 DME indicator indicates the ID but there is no Distance indication..we performed removed and replace on DME-42 RT, IND-42 DME Indicator and the CTL-32 VOR Control but the discrepancy still exist.
What will be the probable cause..
