Narrative:

Upon approach; when going from flaps 1 to flaps 5; we noticed on the flap gauge a flap asymmetry problem. The left flap indicator did not move from the 1 position; but the right indicator moved and indicated normally at the commanded 5 position. We also noted a momentary 'C hydraulic low pres' EICAS message which went out immediately. We told tower that we would need some time to work out the problem. He gave us vectors and then handed us over to approach control where we declared an emergency and worked on the problem. The pilot flying said the controls seemed to feel normal and so we recycled the flaps to the flaps 1 position doubting that we had a true asymmetry. We reselected the flaps to the flap 5 position with the same gauge indicated result. We returned the flaps to the flap 1 position; performed the QRH procedure; and then continued in for a normal uneventful landing.

Title: A B767-300 left flap gauge did not move beyond 1 when Flaps 5 was selected and although the flight controls indicated normal flight with no TE Flap annunciation; an emergency was declared and the QRH TE FLAP procedure was completed with a normal landing.

Narrative: Upon approach; when going from Flaps 1 to Flaps 5; we noticed on the Flap Gauge a flap asymmetry problem. The left flap indicator did not move from the 1 position; but the right indicator moved and indicated normally at the commanded 5 position. We also noted a momentary 'C HYD Low PRES' EICAS message which went out immediately. We told Tower that we would need some time to work out the problem. He gave us vectors and then handed us over to Approach Control where we declared an emergency and worked on the problem. The pilot flying said the controls seemed to feel normal and so we recycled the flaps to the Flaps 1 position doubting that we had a true asymmetry.
