Supplement A-3 Page3of6 8AC

METRO III – ICAO ANNEX 8 INTRODUCTION This supplement provides information relative to the digital flight data recorder (FDR). Although the FDR requires no pilot operations in order for it to automatically record flight parameters, some operators may require that trip and / or date data be set and inserted by the pilot. Faulty operation of the FDR cannot be corrected by the pilot.

SECTION 1 . . . . . . .LIMITATIONS

No Change.

SECTION 2 . . . . . . .NORMAL PROCEDURES

BEFORE STARTING ENGINES . . . Add following procedure.

FLIGHT DATA RECORDER *1. Battery Switches ................................................................................... ON/CHECK FDR POWER FAIL LIGHT ON *2. Inverter Switch ................................................................................ NO. 1 OR NO. 2/CHECK FDR POWER FAIL LIGHT OFF *3. Trip and Date Code Wheels .......................................................................... SET AS REQUIRED *4. Repeat Button ................................................ PUSH AND HOLD THREE SECONDS MINIMUM/ CHECK CYCLE LIGHT ON

NOTE • Normal time required to enter trip and date codes on the FDR magnetic tape is 15 minutes. The amber repeat cycle light should remain on during that time.

• The recording time remaining indicator is redundant and is not operative when the digital FDR is installed.

METRO III – ICAO ANNEX 8 SECTION 3 . . . . . . .EMERGENCY PROCEDURES

No Change.

SECTION 3A . . . . . . .ABNORMAL PROCEDURES The FDR cockpit unit includes an event button which inserts a distinctive code on the magnetic tape in order to highlight unusual occurrences. Push the event button momentarily in order to mark the tape with an event code.

SECTION 4 . . . . . . .PERFORMANCE

No Change.

SECTION 5 . . . . . . .WEIGHT AND BALANCE

No Change.

SECTION 6 . . . . . . .MANUFACTURER’S DATA The FDR records and saves 25 hours of information, in digital format, on an endless magnetic tape. At the end of 25 hours, the recorder begins erasing previous data and inserting new information. The life of the magnetic tape exceeds 8000 hours of use. As installed in AC-670B, the FDR operates and records data at all times AC power is available to the unit. The following parameters are recorded: a. b. c. d. e. f. g. h.

Copilot’s altitude Copilot’s airspeed Pilot's compass heading Vertical acceleration VHF No. 1 or No. 2 transmission events (when pilot’s or copilot’s microphone is keyed) Outer marker beacon reception events Trip and date codes (if entered in accordance with steps *3. and *4. in Section 2, this supplement) Event codes (each time the event button is pressed momentarily)

Elapsed time, since the recorder most recently began to run, is included on the tape automatically.

METRO III – ICAO ANNEX 8 SECTION 6 . . . . . . .MANUFACTURER’S DATA (continued) The FDR contains self test features which will cause the FDR POWER FAIL light on the copilot’s instrument panel to illuminate if any input signal or electrical power faults exist. Therefore, no preflight checks are required, except to monitor the power failure light. Faults causing illumination of the light cannot be corrected by the pilot.

The recording unit is mounted aft of the cargo compartment aft bulkhead. It is contained in a crash and fire resistant case which includes an underwater locator beacon. The pilot has no control over entry of flightand communications data (first six parameters listed above). When the pilot presses the repeat button on the cockpit unit long enough to start the trip and date encoding, the repeat cycle will continue and the repeat cycle light will remain on until the 15-minute cycle is complete. If the cycle is interrupted; for instance, by turning aircraft power off and then back on, the encoding cycle will resume at the point where last interrupted. The flight and communication events data will be recorded, even while the trip and date data are being recorded. Use of the event button during the encoding cycle may garble the trip and date data. If the repeat cycle light remains on for longer than approximately 15 minutes, the trip and date encoder is malfunctioning.
