8 - FLYING A NOISE ABATEMENT<br />
DEPARTURE PROCEDURE<br />
8.6. THE AIRBUS DEPARTURE ANALYSIS SOFTWARE (ADAS)<br />
This <strong>to</strong>ol will be integrated in the PEP environment in 2004, as an "on-ground"<br />
preparation <strong>to</strong>ol in order <strong>to</strong> compute the optimized inputs <strong>to</strong> set in the FMS2-NADP<br />
panel. This will fasten the optimization process, which is currently manual and takes<br />
several hours.<br />
8.6.1. ADAS INPUTS<br />
8.6.1.1. TAKEOFF OPTIMIZATION INPUTS<br />
Temperature, wind, pressure altitude, takeoff configuration (fixed or <strong>to</strong> be optimized),<br />
runway characteristics (Slope, TORA, TODA, ASDA, obstacles <strong>to</strong> be considered,<br />
runway state...). If the TOW is fixed, the <strong>to</strong>ol will maximize the TFLEX value for that<br />
actual weight.<br />
8.6.1.2. NOISE INPUTS<br />
Acoustic constraints, microphone positions...<br />
8.6.1.3. OPERATIONAL FLIGHT PATH INPUTS<br />
Type of <strong>Noise</strong> Abatement Departure Procedure: Close-in, Distant.<br />
Some of the input parameters (acceleration altitude, thrust reduction altitude, rating after<br />
reduction…) may be fixed by the user. If not, the <strong>to</strong>ol will optimize them.<br />
