Contamination / BA on TO calculations
I don't suppose anyone would be so kind as to provide feedback on the following...
I'm looking at an aircraft type where the only performance charts provided by the AOM dealing with contamination / slippery runway (0.02) are:
- Contamination effect on takeoff-distance
- The Effect of slippery runway on landing distance.
Roll-resistant deposits will of course lengthen the takeoff run, and affect both the accelerate and stop distance in ASD calculations. Low braking action will have minimal effect on TOR (unless static TO-thrust is required), but a large impact on the ASD calculations.
When faced with such a lack of data from the manufacturer, are there industry-accepted factors applicable to the "dry/wet runway" charts when faced with poor BA / contamination. As things are now, the only option is to stop operations when BA is under .05 or more than 3mm WED exists.
