Crikies. Up here, the cheapest is around $100/hr USD for a 152.
Good gawd...
When I was in multi the PA-44 Seminole was $144 an hour (instructor was extra). I nicknamed it "Whistling Debt" (because they whistled when they flew over and cost a nickel a second to fly back then). When I was holding short I would sit there and go, "Ka-ching! Ka-ching! Ka-ching!" until I got to fifty cents. "That's a soda. Ka-ching! Ka-ching!"
Wound up doing my MEI and MEII somewhere else. Local flying club. They charged based on the tach for the right engine. Guess which one we shut down all the time for single-engine work up high? Yep.
