Even the northernmost airport in the world with public scheduled flights – namely at Longyearbyen – Svalbard Airport, aircraft are powered by an AXA Power GPU. Unfortunately, there were no polar bears at sight on the day where the photo was taken – or it had forgotten the airside permit. Who knows.
The GPU shown on the Photo is  a 28 VDC unit. The unit was delivered by boat to Tromsø during autumn and further on to Svalbard before the ice made it impossible to access Longyearbyen by sea.
