Hi team.

Quick question when doing take off and landing charts for the test should one be applying the safety factors from 135MOS chapter 10.08 and 10.11 to ones answers?

Thanks in advance.

Hi Thegads,

If you examine the information box on each P Chart, which list flap settings etc, it also lists a distance factor. So no additional safety factors needed.

You can also refer to the note on page 32 of CPL performance textbook.

More importantly, keep in mind that the material in the exams is quite dated. Back in the day, P charts in Australia were required to have various factors included. These factors eventually disappeared from the rule book and migrated to the present documentary requirements, along with a whole bunch of other nonsense.

One of the real problems in the present regulatory environment is that you don't have any idea what factors may, or may not, be included in AFM/POH charts unless you do a detailed bit of research into the design rules for the country of manufacture. Furthermore, during CASA's manic desire to scrap old rules and harmonise with foreign protocols, some unfortunate rules have appeared in the Australian rules which have no historical link to foreign rules. Hence, when a foreign aircraft comes in, it doesn't have those rules included and that can create a bit of a problem for the locals here.

Same sort of considerations apply with the CASA exam weight and balance things where the aircraft have been lifted from Industry (except for the Echo, which appears to have started out as a PA31 but then got the examiner modification treatment). So, the Alpha started as one of Norm Overmeyer's trimsheets around 1980 for the Turbo Lance, Bravo is a Grumman AA-5A Cheetah and Charlie is a Beech Sundowner. As all these are well dated, we have the dreadful mixture of starting points associated with the CAO 100.7 change in definition of "empty weight" quite some years ago.

All part of the good fun, I guess ....
