Awhile back we got a note from a reader based at Denver Centennial. He was concerned about a speed restriction on their ILS Runway 35R. We did a little digging and found that the FAA had already concluded this wasnt such a good idea and removed the restriction. However, this still makes good fodder for these pages, so lets take a closer look.
The article explores the PUFFR ONE RNAV arrival procedure at Denver Centennial (KAPA) and its connection to the ILS Runway 35R, initially prompted by a concern over a past speed restriction.
This RNAV arrival is designed for high-speed jet aircraft, featuring a series of precise speed and altitude restrictions to streamline air traffic control workload by guiding planes directly to the ILS.
The arrival's final speed and altitude restrictions, specifically at FIRPI, are seamlessly integrated to match the initial approach segment of the ILS 35R.
Slower, general aviation aircraft typically bypass such complex RNAV arrivals, instead receiving vectors from ATC to intercept the ILS approach, thereby avoiding these specific arrival restrictions.
