Thunderstorms had been building all day along the rocky mountains requiring aircraft to deviate at all altitudes. The sector was working 10 aircraft at the time of the occurrence. The stuck microphone was noticed and further communications became nearly impossible. Using aircraft in adjacent sectors we were able to resolve the 2 conflictions west/O further incident. However, aircraft began to deviate from assigned routing west/O ATC approval during the frequency outage. This could have created a dangerous situation. Fortunately all worked out. I feel very strongly that cockpits should have lights which indicate a hot microphone.
Original NASA ASRS Text
Title: ZDV SECTOR 24 EXPERIENCED A BLOCKED FREQ DUE TO ACFT STUCK MIC. ROUTE DEVIATIONS OCCURRED DUE TO SEVERE WX.
Narrative: TSTMS HAD BEEN BUILDING ALL DAY ALONG THE ROCKY MOUNTAINS REQUIRING ACFT TO DEVIATE AT ALL ALTS. THE SECTOR WAS WORKING 10 ACFT AT THE TIME OF THE OCCURRENCE. THE STUCK MIC WAS NOTICED AND FURTHER COMS BECAME NEARLY IMPOSSIBLE. USING ACFT IN ADJACENT SECTORS WE WERE ABLE TO RESOLVE THE 2 CONFLICTIONS W/O FURTHER INCIDENT. HOWEVER, ACFT BEGAN TO DEVIATE FROM ASSIGNED ROUTING W/O ATC APPROVAL DURING THE FREQ OUTAGE. THIS COULD HAVE CREATED A DANGEROUS SITUATION. FORTUNATELY ALL WORKED OUT. I FEEL VERY STRONGLY THAT COCKPITS SHOULD HAVE LIGHTS WHICH INDICATE A HOT MIC.
