Crystal oscillator synchronized digital very high frequency omni-range (VOR) instrumentation uni |
April 19, 1994 |
| A very high frequency omni-range (VOR) receiver for use in aircraft radio-navigation, which provides an indication of course deviation that is substantially immune to effects such as reflections in transmitted VOR signals, transients occurring in an aircraft's electrical system and p |

Rapidly responding vertical speed indicator for use in aircraft |
June 26, 1990 |
| A vertical speed indicator uses a substantially rigid hollow closed air chamber; a capillary tube having a reduced inside diameter connected to the chamber for routing atmospheric air from an aircraft static system at a reduced flow rate into the chamber; a differential pressure transduc |

Digital averaging filter particularly suited for use with air navigation receivers |
December 22, 1987 |
| Apparatus for a digital averaging filter, particularly suited for use with an aeronautical navigation receiver, for reducing oscillatory deviation errors that appear in a course deviation voltage produced by the receiver and occur as the result of reflected incoming radio-navigation sign |

Apparatus and method for use in instrument landing system localizer and glide-slope receivers fo |
April 29, 1986 |
| Apparatus and method for use in instrument landing system (ILS) localizer and/or glide-slope receivers for deriving course deviation information are described. Specifically, a detected incoming ILS (localizer or glide-slope) signal is first filtered in order to extract appropriate 90 |
