I have several questions in regards to departures out of airports such as Aspen. It seems there are many different theories as to how depart this airport. The minimum climb gradient departing ASE is 7.5%. Of course this is for an IFR departure. I am wondering if I choose to climb in VFR conditions and visually avoid the highest terrain, what kind of second segment climb gradient is required? For the aircraft that I fly, we would have to depart with little fuel as well as no passengers to be able to attain the 7.5% climb gradient on one engine. Can someone please point me to the regulations that dictate what requirements must be met (both first and second segment climb) for a part 91 operator to depart an airport such as ASE and climb in visual conditions.
