Hi Bob, Stuart and John,
Quick question does '6' come into play in the CPL Perf exam? More importantly 6.1. I know some P charts factor for TODR (less than ideal piloting skills, old plane etc). Will I have to think about manually factoring in the exam on any of the charts?.
I have included the CAO for reference.

Problem is do you know what the basis of the chart you might be using is ?
For the old DCA P-charts, the CAO 101.22 factors were built in. If memory serves me, the 20.7.4 words are the same as 101.22 so all's well.
Foreign charts ? You need to do some homework.

The take-off and landing charts for the exam aeroplane (Echo), are already factored for take-off and landing distance so you don't need to make any further allowances. The distance you obtain from the chart has already been adjusted to allow for an ageing aeroplane, poor pilot technique or assessment of runway surface etc. For example, how long is long grass? What about a runway that has a wet patch at one end? How accurately did assess the wind? etc.
