    ‘Heli Disha’ is an official guidance booklet produced by India’s Ministry of Civil Aviation to help state governments and operators plan, operate and regulate civil helicopter services (helipads, SOPs, checklists). It is primary material for policy and infrastructure discussions especially relevant when evaluating how states facilitate tourism and pilgrimage helicopter services. Use it for helipad planning, helipad operation checklists, and examples of recommended processes for safe tourist heli operations.
  1. Directorate General of Civil Aviation (DGCA). (2024). Air safety circulars & helicopter operations circulars. DGCA, Government of India.
    DGCA publishes operational circulars and safety guidance that directly affect commercial helicopter operators and sightseeing/pilgrimage services.

It identifies causal factors (crew decision-making, weather/CFIT risk in mountainous routes) and gives concrete safety recommendations relevant to pilgrimage heli operations.
  1. Aircraft Accident Investigation Bureau (AAIB). (2025). Preliminary Report — Accident involving BELL 407 (VT‑OXF) in Gangnani, Uttarkashi on 8 May 2025.
