The Part 157 Study

Civil Aviation Rule Part 157 requires that any person who is proposing to construct an aerodrome that is intended to be used for a period of more than 7 days in any 30 consecutive day period must notify the Director.

Following the notification, the Director will conduct an aeronautical study. The purpose of this is to consider the effects that the proposed aerodrome may have on the safe and efficient use of airspace by aircraft, and on the safety of persons and property on the ground. In particular, the aeronautical study considers the following:

  • the effect the proposed action would have on existing or contemplated aerodrome traffic circuits of neighbouring aerodromes

  • the effect the proposed action would have on existing and projected airspace uses

  • the effect the proposed action would have on the safety of persons and property on the ground

  • the effect the existing or proposed man-made objects and natural objects within the affected area would have on the proposed action. 

On completion of this aeronautical study, the Director will issue an aerodrome determination that will be one of the following:

Unobjectionable

An unobjectionable determination shall be made when the Director is satisfied that the proposed action will not adversely affect the safe and efficient use of the airspace by aircraft, nor the safety of persons or property on the ground.

Conditional

A conditional determination shall be made when the Director identifies objectionable aspects of a proposed action but specifies conditions which, if complied with, satisfy the Director that the proposed action will not adversely affect the safe and efficient use of the airspace by aircraft, nor the safety of persons or property on the ground.

Objectionable

An objectionable determination shall be made when the Director identifies objectionable aspects of a proposed action and shall specify the Director's reasons for finding the proposed action objectionable.

If the proposal is found to be unobjectionable or conditional, then there will be a void date specified by which time construction of the aerodrome will need to have been started. This is to ensure that other persons are not penalised due to the aerodrome never being constructed.

It should be noted that the issue of an unobjectionable determination does not pre-empt or waive any district or regional rules or regulations or any other Civil Aviation Rules over the construction or use of the aerodrome. The person proposing to construct the aerodrome should acquaint themselves with any other legal requirements that may be applicable.

Further information on submitting a Part 157 notification and the information that is required to be submitted may be found in Advisory Circular AC157-1 Notice of intention to construct, alter, activate, or deactivate an Aerodrome.
