摘要： Systems and methods to provide alerts when a rotorcraft is in a low airspeed condition. During takeoff or go-around, an aural alert is provided to the pilot before the aircraft slows to less than the effective translational lift speed. The aural, visual, and/or tactile alert gets the pilot's attention to manage the aircraft's airspeed before it is too late in this critical flight phase.

摘要： Systems and methods for improving sink rate alerting for rotary wing aircraft. In one example, the system includes a radio altimeter that produces an altitude value, a processor that is in signal communication with the user interface device and the radio altimeter. The processor receives an altitude value, a position value for the aircraft and landing zone (LZ) information. The processor determines if the aircraft is on an approach to land at an LZ that is raised above surrounding terrain based on the received position value and LZ information. The processor receives sink rate information for the aircraft and generates a sink rate alert based on the received sink rate information and the aircraft altitude value if the sink rate information is greater than a sink rate value adjusted according to the LZ information. An output device outputs the generated sink rate alert. The LZ information includes an altitude value.

摘要： Methods and systems for determining reliability of Global Positioning System (GPS) ground speed. An example system receives GPS track information and GPS ground speed, determines a change in GPS track information and determines reliability of the GPS ground speed based on the determined change in GPS track information relative to the GPS ground speed. The system sets a GPS ground speed based on the determined reliability. A GPS ground speed output is set to zero, if the GPS ground speed is determined unreliable and the GPS ground speed output is set to the GPS ground speed, if the GPS ground speed is determined reliable. The system sends the GPS ground speed output to a Runway Awareness and Advisory System (RAAS). Also, the system sets the GPS ground speed output to zero, if a received GPS ground speed validity signal or a received GPS track validity signal indicate invalid.

摘要： 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.

摘要： Systems and methods for intelligently alerting the flight crew of a cabin depressurization. An example system includes a cabin altimeter that generates a cabin pressure value, an alerting device, such as a speaker system and a processing device in data communication with the cabin altimeter and the alerting device. The processing device determines if there is a problem with the cabin pressure received from the cabin altimeter, determines rate of change of the cabin pressure, and sets at least one of an alert volume or an alert frequency based on the cabin pressure and the rate of change of the cabin pressure if it was determined that a problem exists with the cabin pressure. The processing device also issues a cabin depressurization alert over the alerting device based on at least one of the set alert volume or alert frequency, if there is a problem with the cabin pressure value.

摘要： A system, method, and computer program product for alerting an aircraft flight crew of an inconsistency during an instrument landing system (ILS) approach to a selected runway. The system includes a component configured to receive glideslope and localizer signals, and a component configured to determine aircraft approach angle to runway end. Also, a component configured to alert the aircraft flight crew of an approach inconsistency, if the determined aircraft approach angle to runway end is less than a threshold angular value and one or more parameters based on aircraft position and the received glideslope and localizer signals are met. The component configured to determine aircraft approach angle to runway end determines the aircraft approach angle to runway end based on aircraft geometric altitude, a vertical figure of merit, a horizontal figure of merit, runway elevation, and aircraft distance to runway threshold.

摘要： Systems, methods and computer program products for alerting a flight crew during landing that the tailwind exceeds acceptable limits. The system determines a base tailwind threshold speed for a candidate runway based on a performance constant associated with an aircraft and candidate runway information and determines present tailwind speed. If the tailwind speed is greater than the base tailwind threshold speed, a tailwind alert is generated. Also, the system determines if the aircraft is in a tailwind alerting mode based on configuration of the aircraft and activates tailwind alerting, if it is determined that the aircraft is in the tailwind alerting mode.
