Holding Apron 1r6i6i

The holding aprons are generally the places which are adjacent to the ends of runways where the aircraft park briefly before taking off. Holding apron Aircraft are held due to -runway being busy -engine run up or warming up -cockpit or instruments check up before take off Apron shape -rectangular shape -trapezoidal shape Design Criteria -Adequate space for aircraft to maneuver easily into the runway irrespective of position of adjacent aircraft on the apron -Sufficient room for an aircraft to by parked aircraft on the apron -Configuration Area should be sufficient to accommodate three to four aircrafts of the largest size expected to be handled by the airport -Entry to runway The departing aircraft should enter the runway at an angle less than 90˚ to permit rapid turn off from taxiway -Facility By Apron size should be large enough so that if any aircraft is unable to take off another aircraft is ready to take off can by it. -Holding Bays Small areas located conveniently to hold aircrafts during the busy period until a gate become available -Location

the aircraft and the aircraft should be permitted to enter the runway as close to the end of the runway as possible Then holding aircraft should be placed outside the by route so that blast do not affect the bying aircraft

-Peak Demand During peak periods traffic volume exceeds holding capacity. This result in queuing -The clearance between the wing tips of the parked aircraft should not be less than 7.5m -As far as possible, the entry into the runway should be made with an angle of 30 degrees
