Changes to contingency fuel requirement since the new CASRs have come into force. Under the 'old' rules, contingency fuel was required for both the trip fuel and the destination alternate fuel. Part 135 07.02 now defines trip fuel and destination alternate fuel as separate, and, for airtransport flights, the contingency fuel allowance applies only to trip fuel and not to alternate fuel.
Page 52 top. Delete reference to slope above 1%. That old CAO is no longer in force. Reference to ERSA is now AIP GEN 2.6.
There are a couple of questions in the back of the book that refer to DECLARED DENSITY ALTITUDE. Please ignore these questions. Declared Density Charts no longer exist. They were removed in the Dec 2nd 2021 changes to the CASA legislation.

Since the intoduction of 'typed -in' answers in the CASA Performance exam, a much higher degree of accuracy is required for all calculations. The CPL Performance book is being updated to include examples of this requirement including ETP and PNR calculations. A summary of the new material may be downloaded from here. ETP PNR download .pdf
