Narrative:
While on approach when moving flaps from 20 to 5; we received an EICAS message for te flap disagree. A go-around was initiated and a clearance was received from ATC to climb to 3000 and turn to downwind. An emergency was declared. During climbout the flap handle was moved from 20 to 5 degrees. At level the aircraft accelerated to 220 IAS. The flap gauge was 20 degrees. The aircraft was slowed to within limits. The te flap disagree checklist was completed. Landing was uneventful.
