Final answer:
The maximum normal and permissible N1 and N2 speeds for the N901-N905 models depend on the engine and aircraft design. Specific values are not provided in the given information, so it is best to consult documentation or an expert for precise values.
Step-by-step explanation:
The maximum normal and permissible N1 and N2 speeds for the N901-N905 models depend on the specific engine and aircraft design. The N1 and N2 speeds are associated with the operation of the aircraft's engines.
N1 refers to the rotational speed of the low-pressure compressor, while N2 refers to the rotational speed of the high-pressure compressor or fan section.
These speeds can vary depending on the engine manufacturer and the aircraft model.
However, as specific values are not provided in the given information, it is recommended to refer to the engine and aircraft documentation or consult an expert in the field for the precise values.
