Aircraft
On approach into ZZZ XXR ILS visual. Flaps were stuck at 5. We went around and accepted vectors in order to run the appropriate check list. [ATC was advised]. We had a flap disagree situation and while running the checklist we were able to move the flaps to 10 but that was where it stopped. We ended up using the alternate flaps checklist and landed with flaps 15. It was an uneventful landing and we taxied to the gate.
The FO (First Officer) was flying aircraft on an ILS final for Runway XXR around ZZZZZ and the aircraft was configured with 5 flaps prior to the incident. After ZZZZZ; the gear was lowered and the aircraft was slowed below flaps 15 limiting speed and the extension to 15 flaps was requested. It was noted; thereafter; that the flap indicator showed 5 flaps when the flap lever was set for 15. The flap lever was reset to the indicated flap setting of 5 by the Captain and the decision was made to perform a go around to investigate. No asymmetry was noted with flap lever changes. The aircraft was stabilized in the pattern and the Flaps - Trailing Edge Flap Disagree checklist was executed which directed the use of flaps 15 for landing using the Alternate Flap Extension checklist. The Alternate Flap Extension checklist was executed to configure the aircraft. The aircraft was landed without incident and taxied to the gate.
B737 flight crew reported a Flap Disagree on approach; used Alternate Flap extension and landed without incident.
