Narrative:

A review of the predep WX indicated the approach in use would be expressway visual 31. While loading the FMS; I was unable to select the approach. I found a note on the flight plan and 'built' the approach manually. About 1 hour out of lga; first officer found instructions to create the approach on our FMC. While on approach; tower instructed us to square our turns to final as they wished to depart 2 aircraft prior to our landing. I overflew the centerline and came back toward the centerline. After lining up; first officer advised that I was getting low. Corrected and made a normal landing in the touchdown zone. I don't fly to lga that much and I had never heard these instructions before. I was unsure of what they wanted and while circling I was overly reliant on VNAV path. The approach felt rushed and unprofessional. I should have declined the instructions and flown the normal approach. I had done an approach briefing planning that I could use outside references for pitch guidance; but still failed to use the VASI as much as I could have. In short; even though I planned the approach before I left; it felt like I never caught up.

Title: B757-200 CAPT REPORTS BEING OFF COURSE AND UNSTABILIZED DURING EXPRESSWAY VISUAL TO RWY 31 AT LGA.

Narrative: A REVIEW OF THE PREDEP WX INDICATED THE APCH IN USE WOULD BE EXPRESSWAY VISUAL 31. WHILE LOADING THE FMS; I WAS UNABLE TO SELECT THE APCH. I FOUND A NOTE ON THE FLT PLAN AND 'BUILT' THE APCH MANUALLY. ABOUT 1 HR OUT OF LGA; FO FOUND INSTRUCTIONS TO CREATE THE APCH ON OUR FMC. WHILE ON APCH; TWR INSTRUCTED US TO SQUARE OUR TURNS TO FINAL AS THEY WISHED TO DEPART 2 ACFT PRIOR TO OUR LNDG. I OVERFLEW THE CTRLINE AND CAME BACK TOWARD THE CTRLINE. AFTER LINING UP; FO ADVISED THAT I WAS GETTING LOW. CORRECTED AND MADE A NORMAL LNDG IN THE TOUCHDOWN ZONE. I DON'T FLY TO LGA THAT MUCH AND I HAD NEVER HEARD THESE INSTRUCTIONS BEFORE. I WAS UNSURE OF WHAT THEY WANTED AND WHILE CIRCLING I WAS OVERLY RELIANT ON VNAV PATH. THE APCH FELT RUSHED AND UNPROFESSIONAL. I SHOULD HAVE DECLINED THE INSTRUCTIONS AND FLOWN THE NORMAL APCH. I HAD DONE AN APCH BRIEFING PLANNING THAT I COULD USE OUTSIDE REFS FOR PITCH GUIDANCE; BUT STILL FAILED TO USE THE VASI AS MUCH AS I COULD HAVE. IN SHORT; EVEN THOUGH I PLANNED THE APCH BEFORE I LEFT; IT FELT LIKE I NEVER CAUGHT UP.
