(b)
The data transfer time depends on: 1) The number of disks. 2) The type and size of software files on each disk. 3) The unique protocols and processors of the data loader. 4) The unique internal protocols and processors of the
component. 5) Disks inserted in a timely manner.
(c)
Typical data transfer times are:
1) Operational Program Software (OPS): approximately 5 to 16 minutes per disk; for example, if the OPS has four disks, then the complete installation can take as long as 64 minutes.
2) Operational Program Configuration (OPC): approximately 1 to 3 minutes per disk. 3) Databases: approximately 3 to 15 minutes per disk.

(3) Table 201 - Data Transfer Times
(a)
Table 201 shows data transfer times for components that are approved for on-airplane software installation. Not all components are installed on all airplanes. If a component is installed on an airplane, then there is a software installation procedure applicable to that airplane. The software installation procedure is in the AMM chapter-section given in the table.
(b)
The types of software installed in a component on one airplane can be different than the types of software installed in the component on a different airplane. For example, some ACARS management units have an OPS and database, but other ACARS management units only have an OPS. 1) A component on the list can have some hardware part numbers
that are approved for software installation and other hardware part numbers that are not approved for software installation. An example of this is the ACARS management unit.
2) Refer to airline part number records to find software part numbers for applicable components.
(c)
Data transfer times are approximate times in minutes for software installed from disks with a data loader. Data transfers can fail, and failure of the data transfer will increase the total time necessary for software installation. Data transfer times are supplied only as an aid to help you schedule work.
(d)
The times given are for the installation of one piece of software into one component. 1) If a component has more than one piece of software, then
you must add the time for each piece to find the total data transfer time for the component.
2) If a system has more than one of a given component, and software is to be installed in each one, you must multiply the time given in the table by the total number of components to find the total data transfer time for the system. a) For example, if a left and a right component are
installed on the airplane, you must multiply the time given in the table by two to find the total data transfer time for the two components.

b) Some systems can cross-load software between components. Usually it is faster to cross-load software than to install software with a data loader. The Flight Management Computer System (FMCS) is an example of a system that can cross-load.
