The plane was bought in October 2001 by my plane partner, and I bought half of it in November 2002. It has about 4500 hours on the airframe. I love this plane. It is easier to fly and roomier than the Cessna 152 I trained in.

A nautical mile (knot) is based on the circumference of the planet Earth at the equator. The circle that the equator defines is divided into 360 degrees and each of those degrees is divided into 60 minutes. One minute of arc at the equator is equal to a nautical mile. Therefore, the circumference of the earth at the equator is 360*60 = 21,600 nautical miles. If we ignore the fact that the earth is slightly oblate, and assume that it is a perfect sphere, then one minute along any "great circle" is one nautical mile. Since every longitudinal line pases through both poles, each longitudinal line is a great circle, and so each minute of longitude, anywhere on the globe, is one nautical mile. Knowing this can make estimating distances easy.
A nautical mile is 6,076 feet and 1.1508 statute miles. To convert knots to miles multiply by 1.15, for example, 100 knots is 115 mph.
