Aircraft Engine Out Procedures (EOPs)

APG uses extended climb data to maximize aircraft performance and reduce costs. Many Airplane Flight Manuals (AFMs) give data for an extended level of height. If the standard level off height isn’t high enough to clear the terrain, APG will model an extended climb to preserve maximum takeoff weight. Without this capability, the only other option is to reduce the payload or fuel to level off, accelerate to enroute speed and continue the climb before reaching the terrain. When pilots rely on standard climb only, it can severely reduce the maximum allowed takeoff weights, which means much less payload, an increase in stops, and more fuel costs.

For some aircraft types, First Principles data is available to give pilots information to extend their climb above the terrain by allowing pilots to level off and accelerate when all terrain has been cleared.

When First Principles data is available, APG can leverage the extended 2nd segment climb beyond the level-off height provided in the AFM. In mountainous terrain, this can provide significant increases of additional usable payload capability over AFM methods. This knowledge allows for much heavier maximum takeoff weights, less payload fuel costs, and direct flight to the destination.
