Change 5 - Add Table 4.11 Item for aerodromes with at least 2 straight-in IAP to a single runway

Policy Aim

The aim of the policy is to increase the granularity of Table 4.11 by recognising an additional common operational circumstance.

Proposed Policy

We propose that an additional item in Table 4.11 would specify that where an aerodrome is planned for use as a destination alternate aerodrome, an en-route alternate (ERA) aerodrome or an isolated destination aerodrome, then where the aerodrome has at least 2 operational authorised instrument approach procedures, each of which provides a straight‑in approach procedure to a single runway, the additives of 400ft and 1.5km should be added to the instrument approach procedure (IAP) minima of the second lowest IAP. The existing additives for circling would not apply to this new Item of the Table.

Question 1: Do you agree with the policy aim of inserting an additional Item into Table 4.11 that would apply where the aerodrome approach facility configuration was at least 2 operational authorised instrument approach procedures, each of which provides a straight‑in approach procedure to a single runway, without requiring the additives for circling presently specified?
Question 2: Do you agree that the proposed policy achieves its intended aim?
Question 3: Do you agree with the proposed addition to Table 4.11 of an item that would require additives of 400ft and 1.5km be added to the IAP minima of the second lowest IAP for aerodrome approach facility configuration with at least 2 operational authorised instrument approach procedures, each of which provides a straight‑in approach procedure to a single runway?
