Smithsonian Air and Space magazine had a recent short piece on "Wrong
Way"
Corrigan and his earth inductor compass use.
http://airspacemag.com/issues/2007/february-march/flights_and_fancy.php
In 2001, the PBS program Nova covered the story of a 1947 airliner that
crashed into the Andes. Airspeed had been commonly used for navigation
up
to that point. However, this plane was flying over the mountains and
ran
into the jet stream. The jet stream was not well known or understood at
the time. The additional head wind significantly reduced the ground
speed
without reducing the air speed. As a result, the pilots started their
descent much too soon and crashed.

RE: IATA Regulations
14 CFR 91.205(b) lists the required equipment on a certificated aircraft
when flying under VFR (Visual Flight Rules). One could argue that an
altimeter is a piece of navigation equipment, but the only other
required navigation device is a "Magnetic direction indicator". Sounds
like a compass to me. Before anyone jumps on the "airspeed indicator"
bandwagon, remember, it reads indicated, not true, and it is speed
through the air, not over the ground. Zero wind, OK. Anything else,
who knows? Keeping your flight log up to date?
For those of you who aren't pilots, I'm sorry. For those who are, isn't
this fun?
Oh, and Julie Boatman had the compass fail in AOPA's Cutlass while
bringing it from the purchase location to start the restoration for next
year's give-away. So they aren't completely fail proof. But they are
more reliable than any gyro.
Fly safe.

In fact, it's not just a fall back instrument in the world of general
aviation. There are many aircraft flying today where the lowly compass
is the primary (or even the only) navigational instrument. It has its
idiosyncrasies but once understood, its reliability and predicatability
remain unmatched by more advanced instrumentation.
I recall hearing an instructor once dismissing a gyroscopic heading
indicator as a mere 'luxury'. Still...a sneaky glance at the handheld
GPS never hurts.

No, but that old magnetic compass is still the fall back instrument for
navigation. In fact, I set the gyro compass (heading indicator) to the
magnetic compass every 15 minutes or so on the planes I fly. Some more
modern HIs automatically correct using a magnetic sensor, but the idea
is the same. Don't mess with the magnetic compass, you really want to
be able to depend on it.

Re: IATA Regulations
Don, The "air eligible" label went away. In fact, the announcement for this label requirement came in one IATA edition, but the very next edition had te requirement removed prior to the original implementation date. Therefore, the requirement has never been in effect. I'm glad you raised this Dangerous Goods issue. Very few companies (especially in the information technology line of business) actually seem to know about the IATA 902 requirement to test products and then appropriately mark those products that meet the definition. A product does not have to be an intentional magnet to be deemed magnetized material for air transportation. Instead, a product just needs to be made of steel or some other ferrous material (containing iron). A product may possibly not be an active magnet but still disturb the earth's magnetic fields (causing the fields to go through the large hunk of steel found in the product). Examples I have heard of include steel wire fencing, automobile bodies, etc. In fact for the information technology arena, I find that every 19-inch rack has enough steel to exceed the limits of IATA 902 to be called magnetized material. Hence, 19-inch racks must be air transported as Dangerous Goods and have the UN label 2807 applied to the outside of the packaging. By the way, only IATA 902 and air transportation has this Class 9 Magnetized Material requirement. This does not apply to US-DOT ground transportation or surface ship transportation. In fact, 49CFR only has the forbidden magnetic levels in the regulations (deviate the compass by 2.0 degrees at a distance of 15 feet). If the product exceeds this level, then both IATA and 49CFR forbid the product from being transported by air. But IATA 902 adds a requirement to air transport products as Class 9 Magnetized Material if it deviates the compass by more than 0.5 degrees at a distance of 7 feet but not exceeding 2.0 degrees at a distance of 15 feet. By law, the shipper that introduces the product for air transportation must have a trained person sign the Dangerous Goods documentation. All flights outside of USA use the IATA Dangerous Goods Regulations, and many carriers use IATA for flights even within USA. Although this issue does not normally fall within the domain of ElectroMagnetic Compatibility (EMC) society, the EMC community is best suited for performing the testing of products and for assisting in mitigating the magnetic properties of the products (especially for those that have active magnetic components like motors or have steel structures that has been magnetized through the bending & welding process). I pass on the requirements to fill out Dangerous Goods shipping documentation to the shipping department. NOTE: For those who don't already know it, IATA is the acronym for International Air Transport Association. The IATA Dangerous Goods Regulations is an "easy to use" manual based on the International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods by Air.

RE: IATA 902 Magnetic Testing
Bud I routinely test all our products to the IATA requirements. There are no exemptions the regulations apply to all goods put onto an aircraft. In general I find products which have welded steel are going to produce a magnetic field. With the field most concentrated at the weld points. If it is a rack, it almost always needs to be labelled. Aluminium bodies and riveted construction tends not to be too magnetic and can often go unlabelled. Although on occasion have found fields coming from large sheets of rolled steel. Basically if the product has a lot of ferromagnetic material, it can become magnetised during construction. Also watch out for large coils and transformers, magnetising the surrounding materials. If you are having trouble locating information on IATA testing, I suggest you try the FAA. They enforce the IATA regs within US airspace. -Original Message- From: Pittman, Bud [mailto:bpitt...@lsil.com] Sent: Thu 18/04/2002 20:41 To: emc-p...@majordomo.ieee.org Cc: Subject: IATA 902 Magnetic Testing Although this is not an EMC standard it is related. My lab has been asked to test our products to the magnetic standards of IATA Packing Instruction 902. This test determines the ability of a device to change a compass reading. I have the regulations and know how to do the test, but do not do it routinely. Products that fail this test must be labeled and additional shipping charges are imposed. I know that one of our products fails and we are labeling it. Fines for non-compliance are substantial, yet I am having a hard time finding anyone who knows about or complies with this standard. My questions are: Does anyone else perform this test, or have it performed on their products? What kind of results are you getting depending upon product size, shape, metal content? Are there exceptions or conditions that would exclude product families from this regulation. Any help or discussion would be appreciated.

Re: IATA
John You are absolutely right, the magnetic field limits are all about cargo interfering with a planes navigation systems, and nothing to do with the effect on human's. To carry Hazardous material, a cargo plane must be licensed and has an upper limit on how much mass it can carry. Very few combined passenger and cargo planes are licensed to carry Hazardous material. This can make finding an available plane to ship your goods quite tricky sometimes !

Re: IATA/airfreight and magnetic fields
When you do the measurements it is often very surprising, as too what turns out ot be magnetic, and what is ok. Remember for far field measurements a magnetic field drops of at an inverse cube rate (approx.). So being very crude with the equations (as the physics often hurts my head), if you have a large powerful magnet of say, a 20 cm diameter. At 2.1m the field strength is already reduced to 1/9000th and at 4.6m to nearly 1/10th of the max field strength measured at the magnets face.
