The Pierre Auger Observatory is the world's largest detector for the detection of ultra high energy cosmic rays. It is designed as a hybrid detector with a Surface Detector (SD) and a Fluorescence Detector (FD) as its baseline components. The SD consists of 1600 stations, which cover an area of 3000 km$^2$. The entire field of the SD is overlooked by 27 telescopes, which are located at four FD buildings. The Auger Engineering Radio Array (AERA) consists of more than 150 antenna stations. It covers an area of about 17 km$^2$ and detects radio signals originating from air showers induced by the cosmic ray. The measurement of the air shower is used to reconstruct proparties of the primary cosmic ray particle.

The data read-out of AERA is triggered externally in particular by the SD. This results in many triggers for event that are not relevant for AERA as they are too far away. In addition, not all events of interest yield a trigger. To improve the external trigger, a new reconstruction method for determining the direction of an air shower on trigger level is presented. Based on this method different trigger-conditions are defined and tested. This results in a substantial improvement compared to the current AERA trigger.
