If your aircraft is unable to fly, you don't have to follow the standard instrument departure with OEI, said NBAA Domestic Operations Committee member Steve Leon in this week's NBAA Flight Plan podcast. There are alternatives, such as purchasing an OEI takeoff procedure or developing one yourself. "But there are drawbacks. Purchasing a plan can be expensive. Developing one yourself is extremely difficult and time consuming," Leon added. "That is why so many flightcrews wind up depending on the SIDs."
