One of these approaches will be conducted on aircraft.
6.3.3 OPERATIONAL DEMONSTRATION
The operational demonstration is made to comply with JAR OPS 1.440(f) for aircraft types already approved by JAA for CAT II and CAT III operations. During the operational evaluation period a reporting system is established to monitor CAT II / CAT III success rate and to review unsuccessful approaches. The demonstration is devided into two steps:
1.  
The operational demonstration consists of at least 30 automatic approaches and automatic landings using CAT II/III procedures in CAT I or better weather conditions.

If a success rate of 95 % or better is established at the end of this operational demonstration, the CAT II approach with 100ft DH will be requested. After 6 months of CAT II operations, CAT III A approval with 50ft DH will be requested.

2.  
The additional operational demonstration will consist of performing at least 70 automatic approaches and automatic landings using CAT III procedures in CAT Ill A or better weather conditions. If a success rate of 95% or better is established, and after not less than 6 months of CAT II or CAT III A operations, the CAT III B approval will be requested.

6.3.4 CONTINUOUS MONITORING
Data and statistics to monitor the automatic approach and landing success rate will be established. PIREPS of any unsatisfactory approach and automatic landing or aircraft system malfunction will be retained for a period of twelve months. All the data will be available to the authorities.
6.4 AERODROME REQUIREMENTS
6.4.1 GENERAL
CAT II / CATIII operations are envisaged for a number of airports which fully comply with CAT II / CAT III standards and are approved for such operations by the airport national authorities.
During the operational demonstration period or before conducting approaches andautomatic landings in CAT II / CAT III weather conditions at any airport and, the suitability of the ILS installation and terrain before the runway should be verified by a minimum number of automatic approaches and automatic landings.
Before conducting an automatic approach and automatic landing in CAT II / CAT IIIweather conditions, the crew must verify that Low Visibility Procedures are enforced.
Requirements of AMC to JAR OPS 1.430(b)(4) for airport equipment failure will be used as reference.
6.4.2 RUNWAY CHARACTERISTICS
Required runway length will be verified to comply with automatic landing distance given in the AFM, if this distance is greater than the normal required runway length. Runway width is not to be less than 45m for CAT II / CAT III operations.
6.4.3 OBSTACLE CLEARANCE
For CAT II approach the selected DH must not be lower than the published OCH.
6.4.4  RVR MEASUREMENTS
Touchdown or mid-runway RVR measurement must be available for CAT II and
CAT III A operations.
Touchdown and mid-runway RVR measurements must be available for CAT III B
