Recommendation issued to: Civil Aviation Safety Authority

Recommendation details
Output No: R19970084
Date issued: 20 October 1997
Safety action status:
Background:

This recommendation resulted from a study into violations of controlled airspace.


Analysis

Of the Group-C pilots, only five planned to track more than 5 NM from the boundary.

AIP RAC 44.5 advises pilots wishing to avoid controlled airspace to apply appropriate tolerances to the flight path to ensure that controlled airspace or restricted areas are not infringed. The document gives the following guidance as to appropriate tolerances.

Visual (powered aircraft)
0 2,000 ft AGL 1 NM( 2 NM by night)
2,001 5,000 ft AGL 2 NM ( 3 NM by night)
5,001 10,000 ft AGL 4 NM ( 5 NM by night)

The Bureau believes that these suggested tolerances are insufficient and that the Civil Aviation Safety Authority should amend the AIP to reflect a more appropriate distance for pilots wishing to avoid controlled airspace.

Output text

The Bureau of Air Safety Investigation recommends that the Civil Aviation Safety Authority amend AIP RAC 44.5. to increase the tracking tolerance for pilots wishing to avoid controlled airspace

Initial response
Date issued: 20 October 1997
Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

The following is in response to recommendations R970083 and R970084 contained in BASI Special Study 96254.

R970084

The recommendation that the tracking tolerances be increased for pilots wishing to avoid controlled airspace is impractical. Navigation of aircraft in uncontrolled airspace confined by controlled airspace requires that pilots visually navigate to the present minimum tolerances. This is not to say that pilots should not plan to navigate and fly at greater distances from controlled airspace where the situation permits. This is a training and continuing education issue.

The training aspects will be addressed by our Personnel Licensing Branch and the education requirement will be reaffirmed with CASA's System Safety and Education Branch.
