Performance-based Aerodrome Operating
Minima
• Defines Approach Operations
– Removes Operational use of
– Precision Approach;
– Non-Precision Approach
– Approach with Vertical Guidance
• No reference to sensor or navigation aid
• Performance Based
Approach Classification
250 ft 200 ft
Type A 2D Type B 3D
Type A: Instrument approach operation 250’ or above
Type B: Instrument approach operation below 250’
Horizontal Guidance
Horizontal and Vertical Guidance
• Performance-based classification allows
for gradual phased improvements
• No large step-change in costs to gain
improvement in Operating Minima
Aerodrome Infrastructure
• Improvements can be:
– Visual aids
– Lighting
– Standby systems
– RVR measuring equipment
Aerodrome Infrastructure
• PBN allows vertically guided Approaches at all runways – APV (Approach Procedure with Vertical
Guidance)
• All States urged to provide all instrument runways ends with a PBN Approach – Assembly Resolution A37-11
Performance-based Navigation
• No expensive ground based infrastructure
• Potential for further benefits
• Performance enhancements lead to lower
minima
– Basic principle of a performance-based system
• Can be used in many different situations

Standards Overview
Standards
• Aerodrome Operating
Minima
– Paragraph 4.2.8 outlines
Operators requirement to
establish
• Must consider: – Aircraft performance
– Flight crew experience
– Runway characteristics
– Visual/non-visual aids
– Aircraft equipment
– Obstacles
Standards • Paragraph 4.2.8.1.1 outlines operational
credits for use of – HUD, EVS, SVS, CVS
• Credits include: – Minima below aerodrome operating minima
– Reduced infrastructure requirements
– Reduced visibility requirement
Standards
• The provisions already exist, they can be
used right now
