Abstract

Aviation is a key sector of the economy, contributing at least 3% to gross domestic product (GDP) in the UK and the US. Currently, airline performance statistics are published with a three month delay. However, aircraft now broadcast their location in real-time using the Automated Dependent Surveillance Broadcast system (ADS-B). In this paper, we analyse a global dataset of flights since July 2016. We first show that it is possible to accurately estimate airline flight volumes using ADS-B data, which is available immediately. Next, we demonstrate that real-time knowledge of flight volumes can be a leading indicator for aviation's direct contribution to GDP in both the UK and the US. Using ADS-B data could therefore help move us towards real-time estimates of GDP, which would equip policymakers with the information to respond to shocks more quickly.

摘要

航空业是经济的一个关键领域，在英国和美国至少贡献了国内生产总值（GDP）的 3%。目前，航空公司的业绩统计数据要延迟三个月发布。然而，现在飞机使用自动相关监视广播系统（ADS-B）实时广播其位置。在本文中，我们分析了自 2016 年 7 月以来的全球航班数据集。我们首先表明，使用 ADS-B 数据（可立即获得）可以准确估算航空公司的航班量。接下来，我们证明了实时了解航班量可以成为英国和美国航空业对 GDP 直接贡献的领先指标。因此，使用 ADS-B 数据可以帮助我们实现对 GDP 的实时估算，这将使政策制定者能够更快地获得应对冲击的信息。
