FAA Letter dated 19 Dec 2003 from Robert A. Wright, Manager, General
Aviation and Commercial Division allows certain Elite PCATDS./
Note this is the PCATD version with specific hardware.

There IS a requirement of a CFI for time logged for ratings, experience and
proficiency checks.

There is NOT a requirement for 61.57(c)(1) currency.

You must also report use of the machine annually to the local FSDO and have
a copy of the letter on display.

Elite can furnish a copy of the letter if it is relevant because you own a
PCATD.

I can email you a copy if you need one because you own a PCATD.
