© King Schools, Inc. 2006 800-854-1001 www.kingschools.com RVSM OPERATIONS IN-FLIGHT CONTINGENCY PROCEDURES Problems Maintaining Altitude Due to Severe Turbulence or Mountain Wave Activity Severe turbulence — Tell ATC you are unable RVSM — ATC will apply vectors for separation Mountain wave activity with altitude deviations of: • 200 feet or more — Tell ATC you are unable RVSM — ATC will apply vectors for separation • Less than 200 feet — You can still maintain RVSM — You may request vectors for separation Failure of the Altitude Hold, the Altitude Alerting System, or All Primary Altimeters Notify ATC of the failure Repeat notifi cation to ATC on initial contact on each new frequency ATC will apply 2,000-foot vertical separation or appropriate horizontal separation Request clearance to leave RVSM airspace unless your operational situation requires otherwise Failure of One Primary Altimetry System Cross-check the remaining altimeter with the standby altimeter Couple the functioning system to your altitude hold Notify ATC you are operating with only one primary altimeter RVSM can still be applied If unable to confi rm the accuracy of the remaining altimeter, follow the procedure for Failure of All Primary Altimeters Indications on Primary Altimetry Systems Differ by More Than 200 Feet Follow the procedure for Failure of One Primary Altimetry System Follow the procedure for Failure of All Primary Altimeters PREFLIGHT CHECKLIST Defects in required equipment — corrected Static sources — not clogged Surrounding skin — checked for dents, ice, and chipping or bubbling paint Pitot tubes — checked for bends or clogs All altimeters — set to local setting Each altimeter — reading within 75 feet of fi eld elevation Two primary altimeters — reading within Airplane Flight Manual limits IN-FLIGHT CHECKLIST Altitude hold — working properly Altitude alerter — working properly Primary altimeters — reading within 200 feet of each other At transition altitude — all altimeters set to 29.92 Level off — overshoot no more than 150 feet Altimeters — cross-check at beginning of cruise fl ight and hourly — record at least initial cross-check RVSM NUMBERS 72 hours Time to submit Flight Level Deviation Report 75 feet Maximum difference between altimeters and fi eld elevation 150 feet Maximum assigned fl ight level overshoot 200 feet Maximum difference between primary altimeter readings 245 feet Maximum Altimetry System Error 300 feet Maximum Assigned Altitude Deviation or Total Vertical Error 1,000 fpm Recommended maximum rate of climb or descent, last 1,000 feet 1,000 feet RVSM vertical separation 2,000 feet Vertical separation of RVSM aircraft from non-RVSM aircraft MINIMUM EQUIPMENT REQUIREMENTS • 2 Independent Primary Altimetry Systems • Altitude Alerting System • Altitude Hold System Unable to determine defective system Able to determine defective system |
