CSD

Oil levels in a component can be visually monitored using _____

SIGHT GLASS

This consists of a CSD and AC generator

FALSE

ATA 65

TAIL ROTOR DRIVE

Like any other part of an aircraft, the IDG must be serviced at regular intervals. Reasons for servicing the IDG include: refilling the IDG with oil, filling a newly installed IDG, adjusting the oil level, replacing the filter element, and replacing the cooling system.

TRUE

This consists of one or more voltaic cells connected in series
