An operator shall establish and maintain a monitored [aircraft tracking system](https://avioverse.aero/glossary/easa/aircraft-tracking-system) for offshore operations in a [hostile environment](https://avioverse.aero/glossary/easa/hostile-environment) from the time the [helicopter](https://avioverse.aero/glossary/easa/helicopter) departs until it arrives at its final destination.

AMC Acceptable means of compliance

## AMC1 SPA.HOFO.150 Aircraft tracking system

GENERAL

Flights should be tracked and monitored from take-off to landing. This function may be achieved by the air traffic services (ATS) when the planned route and the planned diversion routes are fully included in airspace blocks where:

(a) ATS surveillance service is normally provided and supported by ATC surveillance systems locating the [aircraft](https://avioverse.aero/glossary/easa/aircraft) at time intervals with adequate duration; and

(b) the operator has given to competent air navigation services (ANS) providers the necessary contact information.

In all other cases, the operator should establish a detailed procedure describing how the [aircraft tracking system](https://avioverse.aero/glossary/easa/aircraft-tracking-system) is to be monitored, and what actions and when are to be taken if a deviation or anomaly has been detected.

OPERATIONAL PROCEDURE

The procedure should take into account the following aspects:

(a) the outcome of the risk assessment made when the update frequency of the information was defined;

(b) the local environment of the intended operations; and

(c) the relationship with the operator’s emergency response plan.

[Aircraft tracking](https://avioverse.aero/glossary/easa/aircraft-tracking) data should be recorded on the ground and retained for at least 48 h. Following an accident or a serious incident subject to investigation, the data should be retained for at least 30 days, and the operator should be capable of providing a copy of this data without delay.
