As I wanted to support my reply with data, I was able to find some documentation for the Airbus narrowbodies which shows a strong impact of the AULOTOLAND (+340 m, that is significant in my view), which is consistent with my experience looking at those kind of tables. The PIREP reports from similar aircraft assess the runway condition as good to medium, and he has an unfactored dry runway landing distance of 2,800 feet. May 22, 2014 · Tech Log - A330 overweight landing procedure = optional? - Hi all Just come up for my first sim since Airbus released the new procedures for inflight landing distance calculation - the one where there is now a flat extra landing distance increment that must be applied, in case of "overweight landing distance Apr 2, 2012 · Conf 3: delta vref = 6 and land dist factor = 1,3 (dry no rev) FULL: delta vref = - and land dist factor = 1,2 (dry no rev) As you can see for the same failure the corrections to be applied are different based on the landing configuration. They also use autobrake systems. 43 < LDA ¶ Wet runway factor The pilot shall ensure that when the runway at the estimated time of arrival may be wet, the landing distance available is at least 115 % of the Oct 15, 2012 · First the need to calculate landing distance before landing, and second, the use of Operational Landing Distances (OLD) as the source of advisory information. gl/2YaemTTo view the next video from the A32 Oct 26, 2021 · For LSZH, you can see that the landing distance for 14 and 16 remains the same, but changes significantly for 34 based on the tailwind component. com Part of this model, affecting both the accelerate-stop computation at take-off and the landing distance computation, are the characteristics of the braking system installed on the aircraft. The recommended safety factor to be added to the In-Flight Landing distance is 15%1. Statistical Data Computation of the final approach speed rarely is a factor in runway overrun events, but an approach conducted significantly faster than the computed target final approach speed is cited often as a causal factor. Jul 29, 2013 · Planning stage: the FLL, Field Length Llimit, landing weight, is derived by taking the destination LDA and finding the weight at which the 'actual' maximum performance Landing Distance factored 60% ( i. AFM or POH landing distance, it will not be possible to achieve the calculated landing distance. does it mean that use of reversers gives no reduction in landing distance? Jan 21, 2021 · Airbus A321 ; Takeoff distance / landing distance Theme . f. Electronic formats may also have the choice between OLD and FOLD, and a selection to increase the factor. Posted September 3, 2019. Apr 9, 2020 · As far as I know, the landing distance calculations on airliners are performed without factoring in reverse thrust, unless the runway is wet. My operational experience is limited to Australia. 60% actual landing distance plus 40% safety margin. 6 or multiply by 1. Apr 21, 2024 · Accurate calculation of landing distance allows pilots and air traffic controllers to assess whether a specific runway can accommodate a particular aircraft under varying conditions. xqi jpqvp zqtj sczscx swah znxsjx tsejr hrrfh oujflv gjxbjjd
