摘要

飞机重量估算是研究人员在使用飞机监控数据时经常遇到的问题。虽然许多类型的分析(如评估飞机声噪、燃油消耗和排放的分析)都需要了解飞机的重量和推力,但这些参数通常无法从监控数据中获得。相反,研究人员通常只能获得飞机的基本状态:横向位置、地面速度和高度。因此,在飞机性能是分析的关键组成部分时,根据这些基本状态估算飞机重量的方法就变得十分必要。本文介绍了两个重量估算模型:一个用于根据起飞数据估算飞机起飞重量,另一个用于根据到达数据估算飞机着陆重量。这些模型在数学上非常简单,但却以飞机认证、航空公司运营和飞机飞行管理系统逻辑知识为基础。利用 240 次空客 A320 航班的机载数据记录进行验证,结果表明所提出的着陆重量估算模型的平均绝对误差相当于最大起飞重量的 2.66%,标准偏差为最大起飞重量的 3.35%。同样,在使用相同的验证数据集时,建议的起飞重量估计模型的平均绝对误差为最大起飞重量的 2.83%,标准偏差为最大起飞重量的 3.55%。

Aircraft Takeoff and Landing Weight Estimation from Surveillance Data
Aircraft weight estimation is a common problem facing researchers working with aircraft surveillance data. Although knowledge of an aircraft’s weight and thrust is required for many types of analyses, such as those evaluating aircraft acoustic noise, fuel burn, and emissions, these parameters are typically not available from surveillance sources. Instead, researchers generally only have access to basic aircraft states: lateral position, groundspeed, and altitude. Therefore, methods for estimating the weight of aircraft from these basic states become necessary in cases where aircraft performance is a key component of the analysis. This paper introduces two weight estimation models: one for the estimation of aircraft takeoff weight from departure data, and another for the estimation of aircraft landing weight from arrival data. The models are mathematically simple but grounded in knowledge of aircraft certification, airline operations, and aircraft flight management system logic. The landing weight estimation model proposed is shown to have a mean absolute error equivalent to 2.66% of maximum takeoff weight and a standard deviation of 3.35% of maximum takeoff weight when validated using onboard data recordings from 240 Airbus A320 flights. Similarly, the proposed takeoff weight estimation model is shown to have a mean absolute error of 2.83% of the maximum takeoff weight and a standard deviation of 3.55% of the maximum takeoff weight when applied to the same validation dataset.
