There seem to have been many approach accidents due to the terrain being higher than expected by the pilot. These incidents include running into hills because the wrong VOR was tuned in, or the aircraft descending more quickly than planned due to distraction from other things going on in the cockpit. I was wondering if civil aircraft designers have ever considered using terrain-following radar like some military aircraft do. I understand that these point forward as well as down, thus causing the aircraft to pull-up in time if there is an obstruction. Apparently very high-speed fighters can fly safely at very low altitudes using this radar. Could this technique be applied for airliners as well? Obviously, such a system would have to "cut out" at a certain altitude so that the aircraft could actually land! I'm not a pilot, just an enthusiast, so I'm sure I am ignorant of many important points here. But I would like to hear what others think. P.S. Love this newsgroup, have learnt a lot from it. Thanks everyone. All opinions are mine, not SGI's. -- Peter Lisner e-mail: firstname.lastname@example.org phone : (415)390-4419 Silicon Graphics Inc.
