After inquiring with the captain why they took more time than expected to reach the New Continent, Perfikot adjusted the ship's navigation equipment according to the captain's response.
The reason for their delay was simply that they couldn't find their bearings and had to proceed along the original maritime route, constantly lowering altitude to confirm their direction, which wasted a lot of unnecessary time.
But after Perfikot improved the navigation equipment, this was no longer an issue.
The upgraded navigation system could confirm directions better, and with Perfikot's suggestion to the captain to rise above the cloud layer to avoid bad weather, Perfikot was confident their return journey would be much faster.
The Duke of Gloucester didn't stay long; after clarifying matters with Perfikot, he had the Flying Airship send him back.
