Module 12.8 Rotorcraft Electrics ATA 24

One of the issues, a student of the EASA part 66 modules is the contents definition or the syllabus.The syllabus as defined in the part 66 guide is too brief. Take for example, thee module 12.8 for rotocraft electrical power, ATA 24 is stated in a number of lines, as given below:
12.8 Electrical Power (ATA 24) 
Level 
  3
1.Batteries Installation and Operation;
2.DC power generation, AC power generation;
3.Emergency power generation;
4.Voltage regulation, Circuit protection.
5.Power distribution;
6 .Inverters, transformers, rectifiers;
7.External/Ground power.  .

Both the students and the training organisation are having too much freedom in interpreting the scope and the depth of the module.

Checking a few established schools in UK, the notes varies from 100 to 220 pages, with different focus and depth.

We had identified the followings as the contents for item 1 : Batteries, installation and Operation...

In module 3, we had covered the construction of batteries.
In this module 12/11, we cover on how the battery is installed in aircraft.
We expect the students to know:
Safety practices
The practical installation and maintenance.
The operation as intended for the aircraft.
The circuit diagram
◦ The advantages and disadvantage of different types of batteries. Example, power to weight ratio, voltage stability and cost.
