Airservices is reducing the minimum holding altitude for the Moorabbin Airport Non Directional Beacon (NDB) approach to improve landing predictability.
What is being changed and why?
Airservices conducts an ongoing improvement program for instrument flight procedures across Australian airports.
As part of this program, it was identified that the lowering of the Moorabbin Airport NDB holding altitude will provide pilots with greater predictability for landing, particularly in poor weather.
Single engine aircraft will hold over areas around Mordialloc, Mentone, Cheltenham and Dingley Village, and twin engine aircraft over areas around Mordialloc, Mentone, Cheltenham, Aspendale and Dandenong South.
A reduction in the holding area due to the change is shown in Figure 1 below.
Figure 1. NDB Holding area: The green lines show the holding areas prior to the change. Smaller area for single engine aircraft and larger area for twin engine aircraft. The black lines indicate the areas post implementation of the change.
What will change?
Residents under the holding areas will notice a change in where aircraft are tracking during poor weather or when pilots require training or to remain familiar with how the NDB approach is flown.
This will occur, on average, approximately 2-3 times per day. Most aircraft using the holding area will be single or light twin engine aircraft.
The noise level change due to the lowering of altitude from 3100ft to 2500ft is 1.8db(A) and it is not anticipated that this noise increase will be noticeable.
When will this change start?
Airservices will be implementing the change on 16 August 2018.
