摘要： An electronic lateral acceleration indicator is provided that gives improved visual performance over previous electronic indicators. In a first embodiment, the lateral acceleration indicator includes a fine tuning element and a high level lateral acceleration element. The fine tuning element provides a precise reading of low level lateral acceleration. This allows a pilot to make small corrections to eliminate small amounts of lateral acceleration. The high level lateral acceleration element provides a strong visual indication when relatively high lateral acceleration is present. The strong visual indication provided by the high level lateral acceleration element increases the probability that the pilot will be made aware of the lateral acceleration. Thus, the lateral acceleration indicator of the present invention provides both fine tuning capability and a strong visual warning of large lateral acceleration to the pilot. In a second embodiment, the lateral acceleration indicator includes a lateral acceleration element that expands as lateral acceleration increases. This allows the pilot to quickly determine if lateral acceleration is occurring. Additionally, the rate of expansion in the lateral acceleration element relative to the increase in lateral mistrim can be tailored to provide improved visual scaling to the pilot.

摘要： Methods and apparatus are provided for displaying terrain data symbology for an aircraft. The apparatus is a heads-down display for an aircraft having a monitor configured to generate a display and a processor coupled to the display. The display has a centerline. The processor is configured to align the centerline of the display with a track of the aircraft, and generate on the display a first symbol corresponding to a terrain and a second symbol corresponding to an attitude of the aircraft. The processor is further configured to position the first symbol and the second symbol with reference to the track of the aircraft.
