Jan, Being somewhat familiar with UH-1's, I don't feel that he is in great danger. Most of the systems are hydraulically actuated and not "fly by wire". I could be wrong, but I think he's safe. Have him broach the question with some of his techies. They should know the system inside out. However, apparently GPS(Global Positioning Systems) are suceptible to Y2K on August 22,1999 for some bizarre reason I don't fully understand. But then again, they didn't have GPS in Vietnam did they??... :0) However, I'm am a little worried that UH-60's and AH-64's may have some vulnerability in their avionics equipment. The Apache's I spent some time around were heavily dependent on computerized flight systems. There could be embedded control chips that need to be individually tested. In either case, the major control systems on all models still tolerate complete electronic failure thus enabling Auto-Rotation capability and all military pilots practice this on a regular basis. Hope this helps. Regards, Ron

Jan, Your son should be fine. Military has been actively working on fixing & replacing receivers. They have the labor and a system in place to correct the problem. NAVSTAR GPS site: laafb.af.mil Commercial users of GPS is where most of my concern is. GPS heavily used for tracking, monitoring and scheduling equipment allocation and movement in agriculture, mass transit, urban delivery, public safety. EXAMPLES - Emergency vehicles: 911, police, ambulance and fire departments - Railroads: Each rail/freight car is basically owned by private investment groups and each car has their own GPS receiver. - Trucking Companies, etc. And GPS isn't just used for navigation. It's also used for precise timing. Some financial/investment firms use GPS to guarantee transactions are recorded simultaneously at all offices around the world. Utilities & GPS As an integral part of any electrical operations system, timing is the technology on which many of its functions are based. Generation and power transfers are planned in advance. Utilities coordinate with each other by making adjustments on a GPS timed schedule. Outages for maintenance are scheduled to ensure that they do not interrupt reliable power delivery. Disturbance records are aligned with recorded GPS time tags for analysis and comparison with related information. Price varies with demand, so even billing is based on time. Advanced applications like locating power line faults (short circuits) and real-time phase measurement require continuous timing with high precision. trimble.com List goes on and on. Cheryl
