Well that was interesting! We flew some gold ore out from Bronson Creek BC to Wrangell AK. Short flight of about 40nm, but in almost overloaded multiengine piston aircaft. I gained new respect for the Boeing 307 Stratoliner. I took off with almost 10 tons of ore and it was a struggle, but we made it. When I first left the runway, I wasn't sure for a while there if it was even going to fly as the Stratoliner was sure wanting to hug the river bed. Couldn't get over 95kts and could just barely climb. And if I had turned to the left towards Wrangell, it probably wouldn't have made the turn. So I went to the right and upriver.
Never did look at the VSI, but my climb rate was sure slow. Eventually, i had enough altitude and a wide enough spot in the river bed to turn a 180 and head for the coast. Ol' Gus in the right seat was sweating bullets and I was too busy trying to keep the big Boeing in the air. But once we made the turn, and I got to 2,500ft altitude, I hit the alt hold and she slowly built up speed. By the time we were back to Bronson Creek, it was acting like a real aeroplane again. From there it was a piece of cake. Just had to keep it from descending too fast at Wrangell...
Fun time!
