| Résumé : | Scholars and experts in air transport generally assume the distance flown between airports is the shortest route (also known as the great-circle distance or the orthodromic route). Howev-er, in the real world, planes follow longer itineraries. This paper reviews the factors of de-tours, based on interviews with pilots and experts in air navigation. Factors relate to (1) technical constraints, (2) natural processes (including meteorological conditions) and obsta-cles, (3) geopolitical factors and (4) social factors, which are all explored in this paper. Their temporary vs. permanent and spatial impact (small vs. long detours) varies signifi-cantly among factors and among cases, as well as their avoidable nature. Appropriate poli-cies could lower detours. In addition, these results echo academic debates on the meaning of distance. |
