Narrative:
While flying the visual approach we turned final for runway 28L with a wbd on runway 28R. He slowed down so much that on short final we lost sight of him. This happens frequently on this approach due to different approach speeds/profiles. I read about a crew being violated for passing and losing visual contact. This needs to be addressed in the approach clearance or on the approach plate (ie, no passing) or aircraft should be staggered with trailing aircraft keeping visual separation.
Original NASA ASRS Text
Title: AN ACR FLC WAS UNABLE TO MAINTAIN VISUAL SEPARATION WITH A SUCCEEDING ACFT WHILE ON A VISUAL APCH CLRNC.
Narrative: WHILE FLYING THE VISUAL APCH WE TURNED FINAL FOR RWY 28L WITH A WBD ON RWY 28R. HE SLOWED DOWN SO MUCH THAT ON SHORT FINAL WE LOST SIGHT OF HIM. THIS HAPPENS FREQUENTLY ON THIS APCH DUE TO DIFFERENT APCH SPDS/PROFILES. I READ ABOUT A CREW BEING VIOLATED FOR PASSING AND LOSING VISUAL CONTACT. THIS NEEDS TO BE ADDRESSED IN THE APCH CLRNC OR ON THE APCH PLATE (IE, NO PASSING) OR ACFT SHOULD BE STAGGERED WITH TRAILING ACFT KEEPING VISUAL SEPARATION.
