Yes basically the same, well apart from:
- Poorer take-off and climb performance on the C150
- C150 being about 1.5" further aft CG
- C150 needing about 1/3rd of the pull force to stall it, particularly significant with flaps down where the C152 needs about 1.5lb and the C150 about 0.5lb
- Some C150s (about half of them) will self-stall with full flaps and full power in a go-around, even if trimmed fully nose-down.
- The different flap lever and flap position indicator
- The extra 10 degrees of flap on the C150
- Most C150s having an ASI in mph whilst most C152s have an ASI in kts
Statistically the C150 has 16 times the C152's stall related fatal accident rate, at-least in the UK where the data's good enough to work it out.
You may guess that I have a bit of an issue with flying schools who allow students to just jump between the two routinely and without any training on the differences.
This is aside from the fact that as a pilot, I personally find the C150 more enjoyable to fly. The light controls and barn door flaps are enjoyable, but I'm under no illusions that they make it safe for a new pilot, it's not outright unsafe, but it's less safe and most importantly - different.
