IFR clearance had included 'VFR on top.' I had stopped at 14500 ft initially and had reported this altitude when checking in with ZDV (after handoff from ZMP). Because of turbulence and proximity to cloud tops, I resumed my climb shortly thereafter. While climbing through 15400 ft the denver controller asked me if ZMP had cleared me for 'VFR on top at 14500 ft.' I responded that no altitude restr had been given, but realized then that I should have reported leaving 14500 ft. In reading up on the subject, the gars are not clear about this requirement to report changing altitudes when cleared to VFR on top. It was mentioned in the aim, however.
Original NASA ASRS Text
Title: PVT INST RATED PLT OF AN SMA SEL FAILED TO RPT LEAVING THE VFR ON TOP CRUISING ALT TO ATC AS RECOMMENDED IN THE 'GOOD OPERATING PRACTICES' OF THE AIM.
Narrative: IFR CLRNC HAD INCLUDED 'VFR ON TOP.' I HAD STOPPED AT 14500 FT INITIALLY AND HAD RPTED THIS ALT WHEN CHKING IN WITH ZDV (AFTER HDOF FROM ZMP). BECAUSE OF TURB AND PROX TO CLOUD TOPS, I RESUMED MY CLB SHORTLY THEREAFTER. WHILE CLBING THROUGH 15400 FT THE DENVER CTLR ASKED ME IF ZMP HAD CLRED ME FOR 'VFR ON TOP AT 14500 FT.' I RESPONDED THAT NO ALT RESTR HAD BEEN GIVEN, BUT REALIZED THEN THAT I SHOULD HAVE RPTED LEAVING 14500 FT. IN READING UP ON THE SUBJECT, THE GARS ARE NOT CLR ABOUT THIS REQUIREMENT TO RPT CHANGING ALTS WHEN CLRED TO VFR ON TOP. IT WAS MENTIONED IN THE AIM, HOWEVER.
