The start-up sequence is a ritual. Unlike a jet’s APU and single-engine start, the ATR uses a cross-bleed start, often requiring the simmer to manually manage the start switches, observe the ITT (Interstage Turbine Temperature) peaks, and introduce fuel at exactly the right moment. The soundscape in X-Plane 11—from the whine of the starter generator to the distinctive thrum of the six-blade props as they enter the low-pitch detent—adds immersive depth.
Takeoff is where X-Plane 11’s physics shine. The simmer must rotate to a precise 8-10 degrees nose-up, then lower the nose to accelerate in the “clean” configuration. The characteristic “ATR bounce”—a slight oscillation due to the stiff landing gear and high wing—is modeled, as is the need to immediately raise the flaps to 15° and then 0° as speed builds. In cruise, the simmer manages not Mach number but True Airspeed (TAS), typically around 280-300 knots. The aircraft is constantly affected by turbulence, requiring small trim adjustments that keep the pilot engaged. atr 72600 x plane 11
