AIRSIDE & AIRFIELD

-airport is a complex intermodal transportation facility: air, roads, rail, water (planes, cars, busses, boats, trucks, subways…) -airport provides air transportation services to people and cargo, and other services to aircraft like maintenance, fuel, catering, cleaning etc -remember the intense regulations? Airport related FAR’s: 71,73,75,77,91,93,95,97,99,101,103,105,150,155,157,161 -airspace designation, air traffic & operating rules, environmental rules, funding rules, and so forth -airports have two major operational components *airside includes the airfield and airspace *landside includes the terminal, ground access, parking (discussed in subsequent unit) -sound management requires thinking about the airfield as four dimensional: length, width, depth, and time

-airfield includes the runways, taxiways, holding aprons & parking areas & penalty box, gate apron/ramp, maintenance and run up apron, vehicle access roads, cargo ramp, separation/clear areas, facilities & equipment areas like navaids or lights or radar, ARFF station, deicing/snow removal, fueling, incinerator/garbage disposal, regional jet terminal & apron, bus stations

-some are Aircraft Movement Areas, some are Non-Movement Areas -rule-of-thumb: ATC controls aircraft movement areas, airport/airlines control non-movement areas -don’t be mislead, a lot of movement happens in “nonmovement” areas; accidents happen, undirected and uncontrolled movement can result in vehicle and aircraft collisions…quite costly in many ways

-let’s take a closer look at some of the airside operating components; remember, some of the practices and design elements are by way of the physics of flight, others are by way of FAA regulation (usually reflecting the physics part)

1. RUNWAYS: -pretty important to an airport, more so to an airplane -FAA regs on virtually everything about a runway from design to use e.g.-length, width, orientation, configuration of multiples, slope, thickness, markings, lights, signage and so on ad nauseum -primary runway oriented to the prevailing wind any parallels too -crosswind runway oriented to the most common non-prevailing wind -runway designation numbers relative to NORTH *9/27 means 90’ E and 270’ W *18/36 means 180’ S and 360’ N -where there are multiple runways like parallels, a letter is added to designate the sequence for an approaching aircraft on the appropriate heading *9L/27R 18R/36L

Runway Length -minimums established for acceleration & deceleration based on: *gross aircraft weight *airfield elevation *climatic conditions including seasonal fluctuations (precipitation, temperature, humidity) *affects of air density on performance -modern jets need 6K to 10K or more

Runway Width -related to wingspan of aircraft (150-200’)

Runway Pavement -asphalt for lighter duty -concrete for commercial service -longevity of pavement depends on use, climate *asphalt = 10yrs+/*concrete = 20yrs+/-

PROPER MAINTENANCE IS PARAMOUNT TO LONGEVITY! Runway Markings -three categories 1) Basic-visual for GA airports 2) Non-precision Instrument for GA & small commercial 3) Precision Instrument for large commercial -displayed markings typically include: *centerline *numerical designation *aiming points along the centerline *thresholds where the number of stripes indicates the width; local condition coordinates for displacement *touchdown zones *sidestripes

Runway Safety Areas (RSA’s) -shoulders and other buffer areas to minimize damage in the event of an overshoot or undershoot

Runway Protection Zones (RPZ’s) -1/2 mile off the ends to provide a clear zone for people and buildings, affording some protection;

usually restricted development and use

Runway Surfaces -five are defined by the FAA, all except #1 are imaginary

1. primary surface 2. horizontal surface 3. conical surface 4. approach surface 5. transitional surface

2. TAXIWAYS -move aircraft to and from the runways, terminal, cargo areas,...
