the expected environment during the demonstration. In addition, for
magnetic tape recording systems, dynamic response checks shall be made
through the recording system and ground station equipment to assure
(1) that freedom from extraneous noise or titrations exists, (2)
that each channel has flat frequency response commensurate with the
parameter to be measured, and (3) that the maximum time lag betweeb
any two or more channels requiring time correlation does not exceed
the time constant corresponding to the channel having the lowest
flat frequency response requirement. Where such check-calibratiom
show significant departures from previous calibrations, a complete
re-calibration shall be made in accordance with 3.1.9.4 herein.
RE-cALIBRATIONS. - All demonstration instru-
3.1.9.4
mentation, if deemed practicable and feasible
by the Test Authority, shall be re-calibrated every three months. The
foregoing period of time may be increased or decreased by the Test
Authority, depending on the number and type of flights scheduled for
continuing or completing the demonstrations. All contractor-installed
instrumentation shall be re-calibrated by the contractor at the con-
clusion of the demonstration. For demonstrations performed at
NAVAIRTESTCEN, whenever re-calibration of instruments is required under
the provisions of 3.1.9.2, 3.1.9.3, or 3.1.9.4, re-calibration of
those instruments for which calibration facilities exist at NAVAIR-
TESTCEN shall be made by NAVAIRTESTCEN. All other re-calibration
required by the aformentioned paragraphs shall be made by the contractor
and shall be witnessed and accepted in accordance with the procedures
of 3.1.9.5. The results of' all re-calibrations for each of the demo-
stration aircraft shall be submitted as revisions to the calibration
apppendices of the rEPort required by 3.19.2.1.
ACCEPTANCE AND WITNESSING PROCEDURES.-
3.1.9.5
Formal acceptance, by representatives of the
TEst Authority, of all instrumentation system installations for each
demonstration aircraft shall be performed at the location at which
the demonstration tests are to be performed, as specified in 3.1.1.
In lieu thereof, and subject to the aPProval of COMNAVAIRTESTCEN,
such acceptance may be performed at the contractor's facility, or
other designated locations at least two weeks prior to delivery of
the aircraft at the test location, to preclude serious delay in the
contractor's development program. Concurrent or prior to the fore-
going acceptance of instrumentation installations, contractor cali-
brations of all instruments shall be witnessed by representatives
of the Test Authority. The Test Authority may designate other
