Abstract

Systems and methods for monitoring Required Navigational Performance (RNP) Procedures and reducing nuisance Enhanced Ground Proximity Warning System warnings including a processor, a memory with RNP instructions and data, and a communication device. The processor accesses the RNP data and instructions from the memory, and uses the communication device to obtain flight information from a Flight Management System of an aircraft. When the processor determines that the aircraft is in RNP space, the processor projects an RNP envelope and modifies a warning envelope of an EGPWS to coincide with the RNP envelope if the EGPWS warning envelope extends farther than the RNP envelope.
