Which statement best describes how to determine OLDA in the ODM?

OLDA is determined directly from the ODM’s Operational Landing Distances Chart. You start with the flap setting you’ll use for landing and the aircraft weight, then read the baseline landing distance from the chart. After that, you apply the appropriate corrections: braking action (how well the runway will brake the airplane), autobrake setting (the distance impact varies with the chosen autobrake level), and any other corrections shown in the ODM (such as runway conditions, wind or slope). The result is the Operational Landing Distance Available for planning that landing under the actual conditions. This is why using the Operational Landing Distances Chart is the correct method—it is the official source that translates weight, flap, braking action, autobrake, and corrections into a concrete landing distance. Other sources like the AFM data or tools might hold raw performance values or calculators, and a general WDR table isn’t the standard method for OLDA, but they don’t provide the integrated OLDA calculation you perform with the ODM chart.
