Patent number: 6710723Abstract: A terrain-awareness system (TAS) provides LOOK-AHEAD/LOOK-DOWN as well as LOOK-UP terrain advisory and warning indications to the pilot of an aircraft of a hazardous flight condition. The TAS includes an airport data base as well as a terrain data base that is structured to provide various resolutions depending on the topography of the particular geographic area of interest. Navigational data from a satellite-based navigational system, such as a global positioning system (GPS), is used to provide a LOOK-AHEAD/LOOK-DOWN and LOOK-UP terrain advisory and terrain warning indications based upon the current position and projected flight path of the aircraft. Since the terrain advisory and the warning signals are a function of the flight path of the aircraft, nuisance warnings are minimized.Type: GrantFiled: September 17, 2001Date of Patent: March 23, 2004Assignee: Honeywell International Inc.Inventors: Hans R. Muller, Kevin J. Conner, Steven C. Johnson

Patent number: 5220322Abstract: Performance of an aircraft ground proximity warning system can be improved, especially where the performance of the aircraft itself has been degraded by a factor such as wind shear, by extending Mode 1 and Mode 3 warning envelopes down to within five feet of the ground. Additional improvements in warnings can be made by monitoring flight path angle, stall margin, angle of attack and deceleration profile, when the aircraft is close to the ground.Type: GrantFiled: August 29, 1985Date of Patent: June 15, 1993Assignee: Sundstrand CorporationInventors: Charles D. Bateman, J. H. Glover, Hans R. Muller

Patent number: 5153588Abstract: A ground proximity warning system for aircraft having flight path angle based warning criteria generates a warning in the event of an excessively steep flight path angle during an approach to a landing. The warning criteria are altered to provide an earlier warning upon the occurrence of a low intensity wind shear or a below glideslope condition. A below glideslope warning system that is biased as a function of decreasing performance shear is also provided. A descent rate based warning system usable above a predetermined altitude may also be provided to supplement the flight path angle warning system.Type: GrantFiled: October 16, 1990Date of Patent: October 6, 1992Assignee: Sundstrand CorporationInventor: Hans R.

Patent number: 4891642Abstract: A wind shear detection system compares air-speed with a composite signal derived from signals representative of longitudinal acceleration, normal acceleration, angle of attack and flight path angle to generate a shear signal. An enhanced version of the system is also compensated for roll angle, radio altitude and flap position. In a modified system, the accelerations are calculated along the velocity vector of the aircraft rather than along the horizontal axis to compensate for inaccuracies that could occur under extreme flight conditions such as high bank angle turns and dynamic maneuvers.Type: GrantFiled: January 11, 1988Date of Patent: January 2, 1990Assignee: Sundstrand Data Control, Inc.Inventor: Hans R.

Patent number: 4727147Abstract: Racemic 1-(4-methoxybenzyl)-1,2,3,4,5,6,7,8-octahydroisoquinoline can be resolved by seeding the supersaturated solution of racemic 1-(4-methoxybenzyl)-octahydroisoquinolinium acetate with its enantiomeric forms and crystallizing the optically active acetate corresponding to the configuration of the seed crystals. The continuous form of the process permits obtaining the two enantiomers together.Type: GrantFiled: October 3, 1985Date of Patent: February 23, 1988Assignee: Merck Patent Gesellschaft mit beschrankter HaftungInventors: Willi Wintermeyer, Fritz Reiff, Hans R.

Patent number: 4725811Abstract: A wind shear detection and alerting system (30) compares inertially derived accelerations with air speed rate to provide a wind shear warning signal. Inertially derived accelerations are used instead of purely inertial accelerations because purely inertial systems generally require a vertical gyro. By utilizing angle of attack (.alpha.) and flight path angle (.gamma.) instead of pitch angle (.theta.) in the calculation, no vertical gyro signal is required and the system will be responsive to vertical as well as horizontal shear conditions. An enhanced version of the system is also compensated for roll angle (.phi.), with the roll angle being derived from the rate of change of heading (.PSI.) to avoid the need for a vertical gyro. The alerting system is capable of providing visual and aural warnings for a variety of wind shear conditions, such as, head shear, tail shear, head shear followed by tail shear and wind shear trend.Type: GrantFiled: February 13, 1986Date of Patent: February 16, 1988Assignee: Sundstrand Data Control, Inc.Inventors: Hans R. Muller, John H. Glover
