TSO-C88b
1. Garmin requests a deviation from the mentioned TSOs for marking the TSO number,
Type/Class and Date of Manufacture, Deviation and Software Part Number on the
exterior of the unit. Instead, Garmin requests to include product name, part number,
serial number, and this statement on the unit’s nameplate label “TSO-C112e See IM for
Add’l Appliance Apprvls.” The installation manual will contain all equipment approvals,
classes/types/ranges and TSO deviations as required by the TSOs, and the software
part numbers for the unit will be available through electronic query within the unit. ELOS
is provided because the installation manual will list all applicable information and the
