India air routes: the national & international network map study
Read the aviation map as a hub-and-spoke system layered on India’s metro geography.
STUDY NOTE 1
Hubs and spokes
Delhi and Mumbai are the international gateways; Bengaluru, Hyderabad, Chennai and Kolkata are secondary hubs; regional routes feed them under schemes like UDAN.
STUDY NOTE 2
Why aviation grew
Distance, terrain (northeast, Himalaya, islands) and rising incomes made air travel the fastest-growing mode; the map now reaches towns like Pasighat and Kullu.
STUDY NOTE 3
Cargo and strategy
Air cargo concentrates at the big hubs; strategically, airfields in the northeast, Andaman and Ladakh carry defence significance alongside civil use.
Map reading task
Mark the six metro hubs and draw spokes to five remote-region airports, noting the terrain reason for each.

UPSC map practice & Geography Optional connection
For UPSC Prelims, pair the location with its state, neighbouring relief and relevant geographic process. For GS I and Geography Optional Indian geography revision, use a simple labelled sketch to explain the relationship rather than replacing the answer with place names. These are Pragnya-authored exercises, not official UPSC previous-year questions.
