## FLIGHT RECORDERCARRIAGE REQUIREMENTS

**FLIGHT RECORDER****CARRIAGE REQUIREMENTS**

- Caj Frostell
- Chief, Accident Investigation
- and Prevention Section
- International Civil Aviation Organization

*International Symposium on Transportation Recorders*

## What is ICAO?

- UN specialized agency for civil aviation
- Chicago Convention (1944)
- 185 Contracting States
- Civil Aviation Authority = State

## Convention on International Civil Aviation

- Chicago Convention and the 18 Annexes are comparable to international law
- Multilateral agreements essential for the regulation of aviation (air traffic services, airport design, navigation aids, communication, aircraft design, personnel licensing)

## ICAO Annexes (18)

- SARPs
- States implement the Standards into their national legislation
- The ICAO Annexes are minimum requirements

## Annex 6 – OPERATION OF AIRCRAFT

**Annex 6 – OPERATION OF AIRCRAFT**

- PART I
- INTERNATIONAL COMMERCIAL
- AIR TRANSPORT – AEROPLANES

## 6.3.3 FDRs – aeroplanes for which the individual C of A is first issued after1 January 1989

- 6.3.3.1  All aeroplanes over 27 000 kg shall be equipped with a Type I FDR.

## 6.3.3 FDRs – aeroplanes for which the individual C of A is first issued after 1 January 1989

- 6.3.3.2  All aeroplanes over 5 700 kg and up to 27 000 kg, shall be equipped with a Type II FDR.

## FDR duration 25 hours

**Type I****	****–****	****32 parameters**
**Type II****	****–****	****15 parameters**

## 6.3.6 CVRs – aeroplanes for which the individual C of A is first issued after 1 January 1987

- 6.3.6.1  All aeroplanes over 5 700 kg shall be equipped with a CVR, the objective of which is the recording of the aural environment on the flight deck during flight time.

## 6.3.8 CVRs – duration

- 6.3.8.1  A CVR shall be capable of retaining the information recorded during at least the last 30 minutes of its operation.

- 6.3.8.2  **Recommendation.– ***A CVR, installed in aeroplanes over 5 700 kg for which the individual C of A is first issued after 1 January 1990, should be capable of retaining the information recorded during at least the last ****two hours**** of its operation.*

## 6.3.9 Flight recorders – construction and installation

- Flight recorders shall be constructed, located and installed so as to provide maximum practical protection for the recording in order that the recorded information may be preserved, recovered and transcribed.  Flight recorders shall meet the prescribed crashworthiness and fire protection specifications.

*Note*.–** ***Industry crashworthiness and fire protection specifications can be fund in documents such as the European Organization for Civil Aviation Electronics (EUROCAE) documents ED55 and ED56A.*

## 6.3.10 Flight recorders – Operation

- 6.3.10.1  Flight recorders shall not be switched off during flight time.

- 6.3.10.2  To preserve flight recorder records, flight recorders shall be de-activated upon completion of flight time following an accident or incident.  The flight recorders shall not be re-activated before their disposition as determined in accordance with Annex 13.

*Note 1*.–** ***The need for removal of the flight recorder records from the aircraft will be determined by the investigation authority in the State conducting the investigation with due regard to the seriousness of an occurrence and the circumstances, including the impact on the operation*

## 6.3.11 Flight recorders – continued serviceability

- Operational checks and evaluations of recordings from the flight data and cockpit voice recorder systems shall be conducted to ensure the continued serviceability of the recorders.

## FLIGHT RECORDER PANEL(FLIRECP)

**FLIGHT RECORDER PANEL****(FLIRECP)**

- SECOND MEETING
- Montreal, 12-20 November 1998
**PROPOSALS**

## FDRs for new aircraft

- No significant difference in the parameter list between:
- -	EUROCAE
- -	FAR
- -	contains the existing 32 parameters in
- 	Annex 6

- FDRs - aeroplanes for which the individual C of A is first  issues  after 1 January 2003.
-  All aeroplanes over 5 700 kg shall be equipped with a Type IA FDR.

- A Type IA FDR shall record the parameters required to determine accurately the aeroplane flight path, speed, attitude, engine power, configuration and operation.  The parameters that satisfy the requirements for a Type IA FDR are listed in xx.

## Parameter list

- The parameters would be recorded only if the data was readily available on the aircraft.  Most new aircraft are capable of complying already.

## CVRs for new aircraft

- CVR, installed in aeroplanes over 5 700 kg for which the individual C of A is first issued after 1 January 2003, shall be capable of retaining the information recorded during at least the last **two hours** of its operation.

## Future Work

- FDR and CVR carriage requirements for existing aircraft (retrofit)
- Impending obsolescence of tape based recorders
- Independant power supplies

- Further review of the EUROCAE parameter list
- Cockpit video recording
- Combined FDR/CVR/video recorder
- Recorders for small aircraft
