2026 Publication Series:

Airspace Structure and Operational Implications

​

This publication series analyzes Thailand’s special-use airspace structure based on AIP ENR 5.1, covering Prohibited Areas (P), Restricted Areas (R), and Danger Areas (D).

 

It also evaluates the operational implications for UAV operators, helping pilots understand how these airspace classifications affect pre-flight decision-making before conducting drone operations.

White Papers in This Series

This publication series analyzes and interprets the classification of P / R / D airspace areas under AIP ENR 5.1, specifically for UAV operators.

WP-01
VTP – Prohibited Area

Legal framework and operational implications of Prohibited Areas under AIP ENR 5.1

WP-02

VTR – Restricted Area

Operational access model for conditional airspace and coordination requirements before flight

WP-03

VTD – Danger Area

Risk assessment of hazardous activities and implications for GO / NO-GO flight decisions

WP-04
Notam สำหรับผู้ควบคุม UAV

Risk assessment of hazardous activities and implications for GO / NO-GO flight decisions

Legal Decision Framework Before Flight

Pre-Flight Legal Decision Model

 

Before conducting any UAV flight, operators should follow this structured assessment:

 

• Verify aircraft and operator status

(Registration / Permit / Insurance coverage)

 

• Review airspace structure

(P / R / D / CTR / TMA)

 

• Check the latest NOTAM

 

• Assess special operational conditions

(e.g., night operations / urban areas / proximity to critical infrastructure)

 

• Determine whether coordination or authorization is required from relevant authorities

 

Final Output of the Assessment

 

The evaluation should lead to a clear operational decision:

 

• Go – Operation may proceed

• Conditional Go – Operation may proceed under specific conditions

• No-Go – Flight should not be conducted

 

All decisions should be based on legal compliance and aviation safety principles.

Future White Paper Series

DTTC will continue publishing white papers in the following areas:

 

• Advanced UAV operations

• Regulatory compliance frameworks and risk assessment

• BVLOS operations and specialized mission frameworks

• Legal liability and insurance considerations
