Why does APG discourage using the “Without Obstacles” option?
Even under Part 91 operations, APG recommends conducting a full obstacle analysis. The aircraft’s performance doesn’t change based on the operating part, and skipping this analysis can compromise safety.
Obstacle analyses may include up to 5,000 surveyed obstacles plus terrain. Rarely is a departure limited by a single, easily avoidable obstacle. Crews must manage multiple potential threats while handling critical tasks like engine shutdown and aircraft stabilization. A full analysis simplifies decision-making and ensures consistent safety across all operations and conditions.
