A Reporter stated that his fractional carrier is transitioning to a new flight and performance planning service for normal and abnormal mountainous departure procedures without flight crew training.

Narrative

Effective immediately; Mountain Airport departure procedures using CessNav have been replaced with a new procedures group. In addition to significant differences in presentation of procedures and data; radical differences in navigation system setup and display; flight crew coordination and procedures are required. Ambiguities exist in the correlation of published minima with multiple alternate departure procedures. Some procedures require the low-altitude reception of low-powered; distant VOR stations in mountainous terrain. Training has indicated that training in these procedures will be accomplished at some point in the future. Apparently a decision was made that simulator training in the new procedures would not be required prior [to] implementation. An instrument departure in mountainous terrain combined with an engine failure is a much more challenging and critical maneuver than any instrument approach. I feel it necessary to express in the strongest possible terms my objection to the implementation of these new; unfamiliar procedures without thorough; realistic simulator training for both crewmembers.
