“I have wondered at times what the Ten Commandments would have looked like if Moses had run them through the U.S. Congress.”
– Ronald Reagan
According to AC 120-91, Part 91 operators can develop EOSIDs on their own — no need to run them through the U.S. Congress. The engineering required to “build” the procedure on paper, however, is daunting. Since f lying an actual engine-out departure is harrowing, individual operators should accomplish EOSID construction in a simulator. With an engine failure at V1, a warm OAT and at gross weight, use the “mark” function of either the simulator itself or the avionics in the cockpit to record fixes as you develop an escape route.
The points on an EOSID can simply be a series of GPS fixes, a radial DME fix using a navaid or an altitude based fix/ turn. While most procedures do not use a ground-based navaid due to accuracy, reliability, difficulty in navigation and possible interference from the very
obstructions you are trying to avoid, they will provide a plan that is better than no plan at all.
The first point on your EOSID should be straight ahead after takeoff to either a fix or an altitude. You would fly to this point while you retract the gear and get the airplane under control. The point should be far enough away to stabilize the aircraft but close enough to allow the first turn in time to avoid obstacles. Subsequent turn points should create a path that leads you to a safe holding pattern in which to climb further, or one that will guide you back to the airport. Once you have a series of fixes, you can save them as a flight plan in your FMS. Review and confirm the fixes as you would your normal route. Then, when ready for takeoff, have the EOSID standing by with immediate execution available. If the takeoff is normal, fly the ATC clearance, published SID or ODP. If an engine fails, select the EOSID, tell ATC you’re an emergency and fly the divine line.
Magenta Line Metaphors
Following the proper path can be a challenge in the air and in life. Especially
if our journey is fraught with obstacles, “Thou Shalt Not’s” or one set of footprints in the sand. So, unless we want to reach our destiny before our destination, perhaps in a harrowing fashion, we shouldn’t wing it. Instead, follow reliable guidance.
The next time you’re in the sim, practice the EOSIDs you already have or develop new ones for the obstacle- challenged airports you use. It should be fun and could help you t•o avoid a kerfuffle. Because if you’re performance limited, you won’t have time to interpret a metaphor, invent an escape procedure or look up the definition of kerfuffle.
Happy Easter my friends. T&T
