What is the difference between an operational checkout and a functional checkout?

Answer 1

b. Operation Check.

This check is performed

primary by the pilot, but may also be

performed by the mechanics after annual and

100-hour inspections. The aircraft flight

manual, the Airman's Information Manual

(AIM), and the manufacturer's information

are used as a reference when performing the

check.

c. Functional Test.

This is performed by

qualified mechanics and repair stations to

check the calibration and accuracy of the avionics

with the use of test equipment while

they are still on the aircraft, such as the transponder

and the static checks. The equipment

manufacturer's manuals and procedures are

used as a reference.

d. Bench Test

. When using this method

the unit or instrument is removed from the

aircraft and inspected, repaired, and calibrated

as required.
