(d)
Each cockpit voice recorder must be installed so that :

(1)
Itreceivesits electricpowerfromthebusthatprovidesthe maximum reliability for operation of the cockpit voice recorder without jeopardizing service to essential or emergency loads;

(2)
Thereis an automatic meansto simultaneously stop the recorder andprevent each erasurefeaturefromfunctioning, within10 minutes after crashimpact; and

(3) There is an aural or visual means for pre.ight checking of the recorder for proper operation.
(e)
The record container must be located and mounted to minimize the probability of rupture of the container as a result of crash impact and consequent heat damage to the record from .re.

(f)
If the cockpit voice recorder has a bulk erasure device, the installation must be designed to minimizetheprobability ofinadvertent operationand actuation of the device during crash impact.

Each recorder container must be either bright orange or bright yellow.] Amdt. 27-22, E.. 10/11/88

FAR27.1459 :[Flight recorders.]

(a)
[Each .ightrecorderrequiredbytheoperating rulesofSubchapterG of thischapter must be installed so that :

(1)
Itis suppliedwith airspeed, altitude, anddirectionaldata obtainedfrom sources that meetthe accuracy requirementsofSecs.27.1323,27.1325,and27.1327 of thispart, as applicable;

(2)
The vertical acceleration sensor is rigidly attached, and located longitudinally within the approved center of gravity limits of the rotorcraft;

(3)
It receives its electrical power from the bus that provides the maximum re-liability for operation of the .ight recorder without jeopardizing service to essential or emergency loads;

(4)
There is an aural or visual means for pre.ight checking of the recorder for proper recording ofdatainthe storage medium;

(5)
Except for recorders powered solely by the engine-driven electrical generator system, there is an automatic means to simultaneously stop a recorder that has adata erasurefeature andprevent each erasurefeaturefromfunctioning, within10 minutes after any crashimpact; and

(b)
Eachnonejectable recorder container mustbelocated and mounted so asto minimize the probability of container rupture resulting from crash impact and subsequent damage to the record from .re.

(c)
Acorrelationmustbeestablishedbetweenthe .ight recorderreadingsof airspeed,al-titude, andheading and the corresponding readings(takinginto account correction factors) of the .rst pilot’s instruments. This correlation must cover the airspeed range over which the aircraft is to be operated, the range of altitude to which the aircraft is limited, and 360 degrees of heading. Correlation may be established on the ground as appropriate.

(d)
Each recorder container must :

(1)
Be eitherbright orange orbrightyellow;

(2)
Have a re.ective tape a.xed to its external surface to facilitate its location under water; and

(3)
Have an underwater locating device, when required by the operating rules of this chapter, on or adjacent to the container whichis securedin such a manner that they are not likely to be separated during crash impact.]
