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
