Thanks for the insight chaps.

I’m used to cruising at approx 90kts in the C152, is that kind of cruise speed achievable in the C150 too? Interesting about the ASI on the C150 generally being in MPH, definitely something to take note of especially on approach! Don’t want to be getting your speeds mixed up.

As an aside, how about the 172. Would I be right to say a cruising speed of 105kts or so is possible in the 172? If true then on anything longer than a 90 min sector it could actually work out cheaper to fly the 172 than the 150 (£74p/h vs £90p/h)

Sorry to bang on about cruising speeds, I just find that published speeds are quite different to what you can actually achieve once up there flying for real.

That may depend on the age of the aircraft and how well it’s maintained. There are other variables such as altitude, gas quality, temperature, etc… but if properly maintained and in good condition the C-172 SHOULD be able to do 105 KTAS at 2000 ft at standard temp and 2300 RPM. In fact, if you went higher (say 6000 ft) you might be able to get 115 KTAS if you were at 2500 RPM. Also, pilot technique, such as not leaning the engine, etc… can affect your performance.

If things are significantly different from the book, I’d be suspicious. I flew a Piper Tomahawk once that was ALWAYS better than the book by 2-5 KIAS. Turned out it had some non-standard cylinders on it of doubtful origin…

I think Cessna’s figures are likely accurate. Oh, and if you’re going anywhere with friends, the C172 becomes even more your friend as you can stuff 3-4 people on board and spread the cost more efficiently than the 150.
