For flight in defined portions of airspace where a reduced vertical separation minimum (RVSM) of 1,000ft (300m) is applied between FL 290 and FL 410, the airplane:1. Shall be provided with equipment which is capable of:a) Indicating to the flight crew the flight level being flown;b) Automatically maintaining a selected flight level;c) Providing an alert to the flight crew when a deviation occurs from the selected flight level. The threshold for the alert shall not exceed ±300ft; andd) Automatically reporting pressure altitude.2. The operator has instituted appropriate procedures in respect of continued airworthiness (maintenance and repair) practices and programmes.3. The operator has instituted appropriate flight crew procedures for operations in RVSM airspace.4. Shall be authorized by CAA for operation in the airspace concerned and in compliance with Attachment 17.The airplane or fleet being authorized on the conditions as set out in the preceding paragraph shall comply with the following:1. Receiving the reports of height-keeping performance issued by the monitoring agencies; and2. Taking immediate corrective action for individual aircraft, or aircraft type groups, identified in such reports as not complying with the height-keeping requirements for operation in airspace where RVSM is applied.Operator authorized by CAA for RVSM operation shall ensure that a minimum of two airplanes of each aircraft type grouping of the operator have their height-keeping performance monitored, at least once every two years or within intervals of 1 000 flight hours per airplane, whichever period is longer. If an operator aircraft type grouping consists of a single airplane, monitoring of that airplane shall be accomplished within the specified period.ATTACHMENT 17 Operating under Reduced Vertical Separation Minimum (RVSM).pdf
