Method and apparatus for microburst and wake turbulence detection for airports
First Claim
1. In combination with an airport, said airport having an airplane runway usable for take-off and landing of aircraft, a control tower within which is housed at least one air traffic controller, said controller being able to observe a monitoring display screen, said screen being used by said controller to determine the altitude and position of aircraft during take-off and landing on said runway, said airport having doppler weather radar for obtaining weather information signals, said airport having surveillance radar for ascertaining position of an aircraft in the vicinity of said airport, and an apparatus for detecting of a meteorological condition known as a microburst and for detecting aircraft wake turbulence within the immediate vicinity of said runway, said apparatus comprising:
- a plurality of wind direction and wind velocity devices mounted directly adjacent to said runway and outward some distance in alignment with said runway along the take-off path and approach path for said aircraft, each said device to output data on either wind velocity and/or wind direction, each said device is in the form of a globular open metallic frame which permits wind to readily pass therethrough, a plurality of wind detection sensors being mounted on said metallic frame in a spaced apart manner, said metallic frames being electrically heated to an elevated temperature, whereby as air passes through said metallic frame the velocity and wind direction of the air can be measured by the rate at which heat is conducted away from said metallic frame; and
a computer for receiving said data from said devices along with said weather information signals from said doppler weather radar, said computer also receiving input signals from said surveillance radar, said computer being connected to said display screen, said computer being programmed to display a colorful pictorial representation of said microburst on said display screen in addition to data from said doppler weather radar and said surveillance radar, said colorful pictorial representation resembling the actual appearance of said microburst in conjunction with the terrain if said microburst could be observed, said computer causing displaying on said display screen the location of said microburst relative to said runway and any said aircraft that may be approaching said microburst, said microburst being displayed on said display screen reasonably accurately in size in relation to said aircraft and said runway, said microburst being displayed on said display screen in a horizontal position relative to said airport and said aircraft, whereby this approaching of said microburst is to be communicated to the pilot of the aircraft by the air traffic controller so the aircraft can take appropriate evasive action.

Abstract
A method and apparatus for detecting specialized meteorological conditions such as a microburst and also the wind condition generated behind an aircraft known as wake turbulence. The method and apparatus of the present invention is designed to display the location of the microburst directly on the flight controller'"'"'s monitoring screen with the flight controller then being able to so inform any pilot of an aircraft of the microburst so that the pilot can take evasive action. The display on the flight controller'"'"'s screen is to be in color. The displaying of the microburst on the screen is to be by means of a computer which utilizes as inputs the conventional aircraft surveillance radar, weather radar and ground radar as well as additional inputs of wind direction and velocity information obtained from detection devices mounted directly adjacent to the aircraft runway and along the approach and take-off areas for the runway.
