Narrative:

1) misset altitude for cruise, 2) center asked altitude, 3) troubleshooting #2 VOR navigation reliability, 4) promptly corrected altitude deviation. Supplemental information from acn 329599: misset altitude indicator for cruise (cleared to 12 KTS set 16 KTS). During climb was troubleshooting #2 VHF navigation reliability flag and overshot altitude.

Title: FLC DEVIATES FROM CRUISE ALT WHILE CHKING PERFORMANCE OF VOR NAV RECEIVER.

Narrative: 1) MISSET ALT FOR CRUISE, 2) CTR ASKED ALT, 3) TROUBLESHOOTING #2 VOR NAV RELIABILITY, 4) PROMPTLY CORRECTED ALTDEV. SUPPLEMENTAL INFO FROM ACN 329599: MISSET ALT INDICATOR FOR CRUISE (CLRED TO 12 KTS SET 16 KTS). DURING CLB WAS TROUBLESHOOTING #2 VHF NAV RELIABILITY FLAG AND OVERSHOT ALT.
