The schedule of test results now includes a column for the x5 test as well.

The schedule of test results now includes a column for the x5 test as well.

I saw that and thought, no it doesn't, then I looked at my test sheets that I designed myself and I have the x5 column in there!, Hmm.. maybe I should pay more attention to what I am filing in on these sheets!!

Here's a bit of a pointer to those who are/maybe going to do any of 2391,2394,2395. If you want an easy reminder or prompt for carrying out the practical assessment when you freeze looking at the test rig, then look at the generic schedule of test results that you will be given, the test sequence is laid out on the model form in the correct order.
