Sitting in a meeting today, a few of us were discussing this approach and wether or not most pilots understand that after the FAF DMYHL, with the prescribed visabilities and the lead in lighting in sight a pilot can continue on the approach but not descend below the MDA. My question is since lead in lighting is a VMC lighting system and the prescirbed minimums are 2 and 1/4 why is it that you can continue on the approach under Instrument Flight Rules? What other protections other than the LIL's, are provided for the aircraft if there is a 90 degree turn? If anyone has flown this approach what are your thoughts on its use in a scenario where the ceilings are almost at minimums? Any thoughts would be great!
