## Discrepancy

GSO - ON APPROACH TO CLT, AFDS SHOWS NO FLARE ARM AT 1,000 FEET.  AUTO PILOT DISCONNECTS SHORTLY THEREAFTER.  THE WEATHER IN CLT WAS BELOW MINIMUMS FOR THESE CONDITIONS SO THE FLIGHT DIVERTED TO GSO. FLIGHT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NR 1 VHF NAV RECEIVER PER MM 34-31-41.  OPERATIONAL CHECK GOOD.
