Aircraft
Autopilot and autothrottles off visual approach into landing runway in VMC conditions. At approximately 225 kts called for flaps 1; as aircraft continued to slow called flaps 5 and at that time noticed flap needle and corresponding flight indications that the flaps had stopped in a position between Up and 1. Both crew members acknowledged this and Captain instructed FO to tell the tower that we needed to break off visual approach and climb to 3000 ft. I took radios since I was still hand flying and instructed FO to start into the QRH. My concern at the time was two jets that were in sequence behind us. FO worked on the issue and after completing the first portion of Flaps leading edge transit light which sent us to the next checklist I decided to [advise ATC]. We were now cleared to maneuver west of the airport area as we continued to work on the issue. At this point I gave aircraft to FO and I entered the QRH from the initial checklist. Leading edge flaps transit checklist lead us to trailing edge flap disagree checklist which lead us to step 5 due to flap needle split/position to extend using alternate flap extension. Alternate flap extension checklist was performed until flaps arrived at a position between position 2 and 5 and stopped. We also at this point did not have the leading edge devices indicating full extension on deployment. It was at this time that FO and I made the decision to employ the most conservative approach and use the Flaps-All flaps up landing checklist due to the potential erroneous conditions/ indications of the aircraft. After completing the checklist a non-event arrival and landing was performed.
