Incident at PENTICTON BC (CYYF) (ATM - inaccurate aeronautical information)


2021-05-03: Two aircraft inbound to Penticton, BC (CYYF) were not heard on the mandatory frequency (MF) 118.5 MHz during their initial call-up. On closer inspection, it was found that calls were received from both aircraft, while the aircraft were receiving broken transmissions from the Penticton (YYF) flight service station. Due to telecommunication (TELCO) problems reported earlier, both transmit and receive functions on 118.5 MHz were switched to backup. The Technology Operations Coordinator (TOC) was advised.
