Mayor Sheila Young • • July 15, 2004 Page 7 of 9 Please note that when other aircraft over 75,000 pounds land on Runways 27L or 27R, the Airport Noise Office contacts those pilots and requests them to use Runway 11/29 in the future. This does not happen frequently and usually applies to chartered flights. Compliance is very good. 10) Please explain the plan for preferential runway use for nighttime diversion of flights to 27L if a second ILS is installed at the North Field. Answer: As discussed with the North Field Group, the Airport would add a noise abatement procedure in the form of a preferential runway use program, directing arrivals to use Runway 27L instead of 27R in order to minimize noise to the extent possible on close -in neighborhoods. Airport staff will work with the FAA and North Field Group to establish the details, including time of day parameters, for the program. At the very least, this could occur during the Quiet Hours program (10 p.m. — 6 a.m.) and may be able to begin, at least for some aircraft, during evening hours. 11) Please explain the planned use of the runways during daytime hours for touch - and -go operations if a second ILS is installed at the North Field. Answer: Today, touch and go operations take place on 27L, which keeps the training flights over industrial and park areas. If two ILS's are installed on North Field, we recommend keeping the touch and go flights on 27L, away from residential areas. To ensure this will continue, instrument arrivals could be directed by the FAA Tower to use 27R in order to achieve safe and efficient separation of aircraft. The Tower has suggested that this is a logical practice to implement. Due to our good weather, the majority of North Field arrivals approach the Airport under "visual" flight rules, and most small planes choose to land on 27R anyway .due to its proximity to North Field facilities. Consequently, most pilots would choose to land on 27R whether there are two ILS's or just one. In addition, during those periods when there no touch and go operations, pilots of corporate jets and/or larger prop planes may request, or be directed by the Tower, to land on 27L. 12) How many instrument landings take place at the North Field on an average daily basis? What is the percentage of ILS arrivals at night? Answer: It is difficult to determine the number of aircraft that fly using instrument flight rules (IFR) and actually use the ILS to land. For example, the FAA Tower counts the number of IFR•and VFR flights per day; however, a pilot may file an instrument flight plan but during clear weather, he may land visually without following the ILS. Conversely, a pilot may fly VFR (visual flight rules) but fly
