When running a search for IFE, Internet or Phone equipment you will sometimes see Not Fitted, Unknown or an empty field in the results.
Not Fitted means there is no system installed. We can positively confirm there is no system rather than leaving the field empty.
Unknown means there is a system fitted, but we have been unable to confirm the exact vendor details.
"-" means the system is not applicable, or has not been been reviewed or populated yet, the latter typically applying to aircraft on order. For example if the aircraft was not equipped with a Business Cabin, the data column 'Business Class Primary IFE Model' is not applicable to show IFE details as the cabin does not exist.
