I remember once making a visit to the tower in K??? with my manuals to explain why we couldn’t do 200kts to the marker on a 3.5deg NPA to a performance limiting runway in a MLW 777-300. Having laid out my case ATC were very understanding...
Not familiar with the Triple but 200kts to the marker on a 3.5deg NPA would definitely be tricky in a 737-800.
