What is the maximum allowable in-flight difference between Captain and First Officer altitude displays for RVSM operations
200 feet
Do Standby altimeters meet the accuracy requirements for RVSM airspace
No
What is the Altimeter tolerance for IFR flight
60 feet on QNH for both altimeters, however if one altimeter is between 60 and 75 feet a re-check can be made at the next destination
