Narrative:

Enclosed here an article from the san mateo times. It is self-explanatory and 'tested by the FAA.' my concern is that this (as many other things being tried on us now) procedure seems to be ok as long as everything goes exactly right. They are currently pushing us closer together at all airports in the landing patterns. What happens on this procedure when an aircraft rolls in the slip stream (of the preceding aircraft) into the one beside it? What happens for any malfunction on final (such as split flaps, loss of an engine) when you are formation flying? They are continuing to squeeze too many of us into the final approach funnel. Sequencing from many directions often causes flight paths to overlap.

Title: REPORTER EXPRESSES CONCERN OVER PROPSED LDA APCH AT SFO.

Narrative: ENCLOSED HERE AN ARTICLE FROM THE SAN MATEO TIMES. IT IS SELF-EXPLANATORY AND 'TESTED BY THE FAA.' MY CONCERN IS THAT THIS (AS MANY OTHER THINGS BEING TRIED ON US NOW) PROC SEEMS TO BE OK AS LONG AS EVERYTHING GOES EXACTLY RIGHT. THEY ARE CURRENTLY PUSHING US CLOSER TOGETHER AT ALL ARPTS IN THE LNDG PATTERNS. WHAT HAPPENS ON THIS PROC WHEN AN ACFT ROLLS IN THE SLIP STREAM (OF THE PRECEDING ACFT) INTO THE ONE BESIDE IT? WHAT HAPPENS FOR ANY MALFUNCTION ON FINAL (SUCH AS SPLIT FLAPS, LOSS OF AN ENG) WHEN YOU ARE FORMATION FLYING? THEY ARE CONTINUING TO SQUEEZE TOO MANY OF US INTO THE FINAL APCH FUNNEL. SEQUENCING FROM MANY DIRECTIONS OFTEN CAUSES FLT PATHS TO OVERLAP.
