Runway hotspots (some FAA Regions refer to them as
high alert areas) are locations on particular airports that
historically have hazardous intersections. These
hotspots are depicted on some airport charts as circled
areas. FAA Regions, such as the Western Pacific, notify
pilots of these areas by Letter to Airmen. The FAA
Office of Runway Safety website )
has links to the FAA regions that maintain a
complete list of airports with runway hotspots. Also,
charts provided by private sources show these locations.
Hotspots alert pilots to the fact that there may be a lack
of visibility at certain points or the tower may be unable
to see that particular intersection. Whatever the reason,
pilots need to be aware that these hazardous intersections
exist and they should be increasingly vigilant when
approaching and taxiing through these intersections.
STANDARDIZED TAXI ROUTES
Standard taxi routes improve ground management at
high-density airports, namely those that have airline
service. At these airports, typical taxiway traffic patterns
used to move aircraft between gate and runway
are laid out and coded. The ATC specialist (ATCS) can
reduce radio communication time and eliminate taxi
instruction misinterpretation by simply clearing the
pilot to taxi via a specific, named route. An example of
this would be Chicago O’Hare, where the Silver Alpha
taxi route is used to transition to Runway 4L. [Figure 2-6]
The “Silver A” route requires you to taxi via taxiway
Alpha to Alpha Six, then taxiway Juliet, then taxiway
Whiskey to Runway 4L. These routes are issued by ground
control, and if unable to comply, pilots must advise ground
control on initial contact. If for any reason the pilot
becomes uncertain as to the correct taxi route, a request
should be made for progressive taxi instructions. These
step-by-step routing directions are also issued if the controller
deems it necessary due to traffic, closed taxiways,
airport construction, etc. It is the pilot’s responsibility to
know if a particular airport has preplanned taxi routes, to
be familiar with them, and to have the taxi descriptions in
their possession. Specific information about airports that
use coded taxiway routes is included in the Notice to
Airmen Publication (NTAP).
