Sometimes, a small proceduere change can result in large savings for the airline companies.
For those off you not familiar with turboprop operations, here is a short description of the engine start procedure:
1. Start one engine. It will run in feather (low RPM). Time: 30 sec.
2. Set the propeller control to AUTO or 100% (depending on engine variant). The propeller RPM will increase. Time: 30 sec.
3. Repeat for the other engine.
Starting both engines this way takes 2 minutes. This is how most pilots learn to start the engines, but by alterning the procedure, time and fuel is saved.
