During an emergency, like a rejected takeoff (from the opposite direction), the blast pad becomes a stop way of additional surface on which to slow and stop the aircraft. Jet exhaust is very harsh, and over time can damage the area surrounding the runway (i.e., the grass, dirt, gravel, etc.)īlast pads protect the area immediately behind the runway threshold.Ģ. Aircraft Taxiing into Position for Takeoff (We know it is taxiing because it has crossed the hold line.) Blast pad / Stop Waysįirst, to the aircraft’s right is the blast pad (Figure 3): the purpose of blast pads is two-fold:ġ.

To get to the runway, crews move along the assigned taxiways, following the yellow center stripe and all ground control instructions and taxiway signs until they reach the hold line at the assigned runway.Īlong the way, crews must stop at all hold lines unless the ATC Ground Control clears the aircraft to move. Taxiways and any other non-runway surfaces are painted with yellow markings, while only runway surfaces are marked in white. To guide crews along this route, taxiways and runways are marked with standardized markings painted on the paved surfaces and further guided by signs. General aviation aircraft typically call Ground Control for taxi instructions.ĭuring this period, the pilot has received taxi instructions as to which runway to use and which taxiways to take to get to the runway. When an airline aircraft is ready to leave the gate, the crew gets permission for “pushback.” The aircraft is guided by ground personnel away from the gate to a position where the pilots can taxi forward safely. Movement in the parking area is controlled either by Ground Control, or at larger airports local ramp controllers. There are the parking ramps, taxiways, and runways. Basic Airport Layout (Partial View of JFK International) Kennedy International Airport (Figure 1), we can see examples of most major portions of the airport.

Under normal operations, this guidance is mandatory, so pilots must recognize and know what these markings mean. I'm sure there are other examples but it's a safe assumption that a runway's magnetic heading will be directly related to it's number but not always.As pilots taxi to or from takeoff or landing, especially at major commercial airports, markings on the taxiways and runways provide important guidance. In other cases a runway will have been numbered decades ago but due to the shift in the magnetic poles the runway's magnetic heading will no longer corrispond to the runway number. In some cases with 4 parallel runways they'll name 1 pair 27 L/R and the other pair 26 L/R even though all 4 runways have the same magnetic heading. Sometimes runways numbers don't match up with their magnetic heading but that is usually only found at airports with numerous runways. That means that even though a runway might be facing West to East the number might be 25 (250 degrees) not 27 (270 degrees) due to the variation to the magnetic poles. 19th February 2004 at 17:13 - Edited 1st January 1970 at 01:00Īs Bhoy stated it's based on compass or magnetic heading.
