.  The total number of approaches, by aircraft type, where the airborne CAT II or III equipment was utilized to make satisfactory, actual or practice, approaches to the applicable CAT II or III minima.
.  The total number of unsatisfactory approaches by airfield and aircraft registration in the following categories.
(a)
Airborne equipment faults

(b)
Ground facility difficulties

(c)
Missed approaches because of ATC instructions

(d)
Other reasons

The continuous monitoring should permit the detection of any decrease in the levelof safety before it becomes hazardous. The operator must continue to check his results and to take adequate actions by modifying the operating or maintenance procedures if necessary. The monitoring may also permit problems to be detected on a specified airfield (ILS , ATC procedures, etc.).
The data must be retained for a period of 12 months.
3.8 AUTOLAND IN CAT I OR BETTER WEATHER CONDITIONS
3.8.1 GENERAL
Some operators may wish to perform automatic landings in CAT I or better weather conditions for training purpose or to record data for an operational demonstration or even at crew discretion.
Some guidelines are given below on the conditions, which must be considered by the airline before authorizing its crews to perform automatic landings.
3.8.2 AIRPORT REQUIREMENTS
The Automatic Landing System performance has been demonstrated during type certification with CAT II or CAT III ILS qualify beam, nevertheless automatic landing on CAT I ILS quality beam is possible provided the Airline has checked that the guidance below 200ft is satisfactory.
Operators should interrogate the airport authorities on ILS ground equipment quality and on experience with other operators. They should check with the authorities that specific restrictions do not apply at airports with CAT I only capability.
Terrain profile before the runway threshold has also to be considered since it may significantly affect the automatic landing system performance.
It is generally accepted that automatic landings in CAT I or better weather conditions are performed without activation of the low visibility procedures.
In particular, ILS-sensitive areas will not be protected which means that ILS fluctuations may be encountered due to the presence of an aircraft or a vehicle taxiing in the sensitive areas. On that same aspect, airport authorities should be interrogated and in some cases it may be necessary to protect the ILS sensitive areas before an automatic landing is performed.
3.8.3 CREW AUTHORIZATION
The airline must establish its own standards to authorize pilots for automatic landings. Only pilots authorized by the airline can perform automatic landings.
3.8.4 CREW PROCEDURES
An automatic landing may only be performed on runways listed in the airline's operations manual.
The operator must establish procedures and techniques similar to CAT II / CAT III operations (refer to FCOM).
