Indian airspace covers a significant corridor between Europe/Middle East and Southeast Asia/Far East. Many international flight routings — whether bound for Bangkok, Singapore, Kuala Lumpur, or onward points — pass through one or more of India’s Flight Information Regions. If your aircraft transits Indian airspace without landing, you need an overflight permit (also called a transit permit or airspace entry clearance).
This guide explains the difference between an overflight permit and a landing permit, what’s required, and how the application process works.
What Is an Overflight Permit?
An overflight permit is official clearance for a foreign-registered aircraft to transit Indian airspace without landing at any Indian airport. It is issued by the Directorate General of Civil Aviation (DGCA), India, under the Ministry of Civil Aviation.
Unlike a landing permit — which authorises the aircraft to land — an overflight permit concerns only the passage of the aircraft through Indian airspace within a defined time window.
India’s Flight Information Regions (FIRs)
India manages two large FIRs:
- Mumbai FIR (VABBF): Covers the western portion of the Indian subcontinent, including airspace over the Arabian Sea and the west coast. Most flights from the Middle East or Europe that transit India pass through Mumbai FIR.
- Chennai FIR (VOMFF): Covers the eastern portion, including the Bay of Bengal region. Flights routing from South Asia toward Southeast Asia typically transit this FIR.
Some flight plans transit both FIRs — for example, a routing from Dubai to Bangkok that crosses the entire subcontinent. In this case, one overflight permit covers both FIRs as long as the routing and dates are correctly stated in the application.
Who Needs an Overflight Permit?
- Foreign-registered civil aircraft transiting Indian airspace without landing
- State aircraft (government/military) — processed through MEA diplomatic clearance
- All aircraft categories: private, charter, cargo, medical, survey
Indian-registered aircraft operating within India do not require an overflight permit for domestic flights.
Documents Required
- Aircraft registration certificate
- Certificate of Airworthiness (current)
- Certificate of Insurance
- Noise certification
- Route details: entry point into Indian FIR, exit point, altitude/flight level, estimated time of entry/exit
- Crew names and passport copies
- Purpose of flight
- Operator/owner details
Processing Timeline
Standard overflight permits are typically processed in 3-5 working days. Emergency or medical overflights can be expedited to 24-48 hours through the DGCA Air Transport Division.
Step-by-Step Application Process
Step 1: Appoint Your India Handling Agent
Even for overflights where you never land in India, the permit application must be submitted through an India-based licensed agent. Aileron Air manages overflight permits as part of our Landing and Overflight Permits service.
Step 2: Provide Documents and Route
Send the document set and your precise routing (entry/exit waypoints and times) to Aileron Air. We review and file immediately.
Step 3: DGCA/MoCA Processing
The application is processed by the DGCA Air Transport Division. For most standard routings, processing is straightforward. For unusual aircraft categories or restricted area overflights, additional reference may be required.
Step 4: Permit Issued
The overflight permit is issued as a PDF/official letter specifying your aircraft, routing, and validity dates. Your crew carries it on board and can present it to ATC on request during transit.
Step 5: ATC Coordination
When your aircraft enters Indian airspace, the on-board permit is your authority. ATC manages the actual routing. If your crew is asked to deviate from the planned routing — for weather or traffic — the permit still remains valid as long as you transit the correct FIR(s).
Combining Overflight and Landing Permits
Many operators on multi-sector trips need both permits — for example, an aircraft routing from Dubai → Bengaluru (landing) → Singapore (overflight). In this case:
- Landing permit for the Bengaluru sector
- Overflight permit for the transit of Chennai FIR on the Bengaluru → Singapore leg
Aileron Air coordinates both simultaneously to eliminate coordination gaps and ensure the complete routing is covered.

Frequently Asked Questions
Q: Is an overflight permit required for every transit of Indian airspace?
A: Yes. Every transit by a foreign-registered civil aircraft through Indian FIR airspace requires a valid overflight permit, regardless of altitude or duration of transit.
Q: How long is an overflight permit valid?
A: Overflight permits are typically issued for specific dates or a defined window (e.g., valid for 7 days for return routing). Discuss your schedule with Aileron Air and we will structure the application for appropriate validity.
Q: What happens if my aircraft enters Indian airspace without a valid overflight permit?
A: ATC may require the aircraft to exit Indian airspace via the nearest point or divert to an Indian airport. Depending on the circumstances, a fine may be levied. This is a regulatory risk that is easily avoided with advance planning.
Q: Can I get an overflight permit for the same day?
A: In genuine emergencies (medical, technical diversion), DGCA can issue emergency overflight clearances within hours. This is not a routine service and is for exceptional circumstances only.
Aileron Air handles overflight permits for all Indian FIRs as a standard service, typically within 3-5 working days. Contact us with your routing details today.
