What is ICAO?

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

3
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)

4
ICAO Annexes (18)

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

5
Annex 6 OPERATION OF AIRCRAFT

• PART I
• INTERNATIONAL COMMERCIAL
• AIR TRANSPORT AEROPLANES

6
6.3.3 FDRs aeroplanes for which the individual
C of A is first issued after1 January 1989

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

7
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.

8
FDR duration 25 hours

• Type I 32 parameters
• Type II 15 parameters

9
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.

10
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.

11

• 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.

12
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.

13

• 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.

14
6.3.10 Flight recorders Operation

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

15

• 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.

16

• 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

17
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)

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

19
FDRs for new aircraft

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

20

• 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.

21

• 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.

22
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.

23
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.

24
Future Work

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

25

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