How would a thicker atmospher and weaker gravity affect chance takor's hang gliding attempt?

Explanation:

First of all, a thicker atmosphere by which I assume you mean increased pressure and a weaker gravity does not go hand in hand. A skinnier atmosphere outcomes in weak gravity due to loss of gases.  

An improved atmosphere of pressure will allow more raise to be produced while gliding on a hang.  The same would refer to a lower gravity.
