C150 vs C152
Hi. I'm in an unfortunate situation where both the school 152's have been taken for their annual inspections at the same time, and we have a temporary C150 in the meantime (added to which I'm also waiting for a slot for my QXC!!). To put it bluntly, it seems a bit of a dog. The ASI is calibrated in mph and it seemed to be giving a cruise of about 70-75kts (equivalent) at 2200 rpm on the first flight I had in it. Is this normal variation? I thought the performance would be similar to a 152 (of which so far I've flown 3 and all seemed to perform almost identically) though this seems markedly slower at the same power.
