What is a CFM56?

I went into a 2,200 ft(30 ft altitude) strip once and will probably do 
it again. I would not like to land there on a regular basis without 
short field training in the LNC2. This airport was in Saluda, VA(W75). 
The airport had a great approach with no trees at all for at least 1/4 
of a mile.

I based my plane at Plymouth, MI(1D2) for 3 months, in order to try out 
their 2,500 ft runway at 700 ft altitude. I felt that it was unsafe. If 
I had lost the brakes, I would have ended up on a pretty busy road that 
was just 50 ft off the end of the runway.

My current airport is Oakland SW, MI(Y47). The runway is 3,100 ft(930 
ft altitude). With 50 ft trees surrounding the runway, I consider it 
marginal for landing. I have taken off at 1,930 lb. at 75 degrees 
Fahrenheit.

I have been on the waiting list for the Pontiac, MI(KPTK) airport for 8 
years. They tell me that I should get a hanger in about another 15 
years. We are pretty crowded here in the Detroit area.

If you are at 4,000 ft with a 45 degree Celsius temperature, your 
density altitude will be about 8,000 ft. At landing speeds the 
differential in your IAS and TAS will be about 12 kts. It will 
therefore take a little longer to land and takeoff. Don't forget of 
lean.

The LNC2 will get out of anything that it can get into. How clear your 
approach is and whether or not you have a safe overrun if something 
goes wrong (and it will) need to be considered.
