+Introduction
+-------------------------
+
+In this example, we modify the simple wing model proposed by Prof. Warren Hoburg in his thesis to create a simple aircraft model compatible with signomial programming (SP). 
+
+```python
+
+from gpkit import Variable, Model, SignomialsEnabled, VarKey, units
+import numpy as np
+
+
+class SimPleAC():
+
+```
