The choice of fleet by a given airline must consider different elements associated with both the aircraft and the airports to be operated, making it necessary a method to assist the aircraft choice process. This study assesses the take-off runway distance requirement of different aircraft models and compares the requirement to the take-off runway distance available at a group of airports. Using the Herfindahl-Hirschman index HHI , the methodology consider the analysis of take-off runway length available on 80 Brazilian airports and compared it to the take-off distance required for combinations of aircraft model, engine model and flight range, considering the take-off performance of the aircraft models with maximum payload weight. In total, routes of four Brazilian airlines has been adopted to simulate the most profitable operating scenario. The result presents the take-off performance of different aircraft models and allows a performance comparison between them. In addition, this research investigates which is the most common flight range in Brazil, and what influence it exerts in the aircraft take-off performance, and contributes to a better match between the aircraft used and the airport operated in fleet optimization.
Airport is situated at sea-level Standard temperature of 15o C at the airport Runway is leveled in longitudinal direction. No wind is blowing on runway Aircraft is loaded to its full loading capacity No wind is blowing on the way to destination Standard temperature exists along the way. The aircraft should come to a stop within 60 percent of landing distance assuming that the pilot makes an approach at the proper approach speed and crosses the threshold of the runway at a height of 15 m 50 ft The runway of full strength pavement is to be provided for the entire landing distance. Take-off distance must be, for a specific weight of aircraft, percent of the actual distance the aircraft uses to reach a height of The upward slope of clearway from the end of the runway shall not exceed 1.
As per ICAO recommendation, minimum width of safety area for instrumental runway should be a 78 m b m c m d m Ans: c. As per ICAO, for A, B, and C type of airports, maximum effective, transverse and longitudinal grades in percentage respectively are a 1.
If runway is number is as Runway 09, it indicates the orientation of runway towards east. The percentage of time in a year during which the cross wind component remains within the limits. No wind 2.

According to the International Civil Aviation Organization ICAO , a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft ". Runways may be a man-made surface often asphalt , concrete , or a mixture of both or a natural surface grass , dirt , gravel , ice , sand or salt. Runways, as well as taxiways and ramps , are sometimes referred to as "tarmac", though very few runways are built using tarmac. Runways made of water for seaplanes are generally referred to as waterways. Runway lengths are now commonly given in meters worldwide , except in North America where feet are commonly used. In January , aviation pioneer Orville Wright underlined the need for "distinctly marked and carefully prepared landing places, [but] the preparing of the surface of reasonably flat ground [is] an expensive undertaking [and] there would also be a continuous expense for the upkeep.
Пальцы Беккера схватили воздух, а дверь повернулась. Девушка с сумкой была уже на улице. - Меган! - завопил он, грохнувшись на пол. Острые раскаленные иглы впились в глазницы.
