Guidance on IFR Operations and Minima

This guidance provides pilots with essential information regarding the operational limits and requirements for IFR (Instrument Flight Rules) pertaining to helicopter operations. It outlines how to establish and apply minima for take-off, approach, landing, and alternate heliports, ensuring calculations account for aircraft performance, crew competence, and environmental conditions.

Key points

• Operators must define specific operating minima for each heliport used.
• Instrument approach procedures need to be approved by the relevant state authority.
• Minima for approach and landing must be based on visibility and decision height, especially in low visibility conditions.
• For IFR operations, both decision height and runway visual range must be strictly adhered to.
