January 22, 201313 yr Just one example for KSEA ILS 16L. On Flightaware is says KARFO @ 3200ft but on Avivla EFB it says 1900ft. Thats a big hard alt difference!
January 22, 201313 yr The official chart should be the trustworthy one. The EFB data comes from Navigraph and while I really appreciate their sim solution being affordable for us armchair pilots, they sometimes feature such errors like on the altitude constraints. :( Well, if you report those errors to them, they can correct them in the next revision.
January 22, 201313 yr http://aeronav.faa.g.../00582IL16L.PDF It only takes a few seconds to find a chart at FAA website. http://aeronav.faa.gov/digital_tpp.asp?ver=1301&eff=01-10-2013&end=02-07-2013 David Chen
January 22, 201313 yr The FAA chart shows KARFO at not below 3200. The next is DGLAS at not below than 1900. Avivla EFB would appear to have misread the chart based on the OP. Gerry Howard
January 22, 201313 yr Just a note: the charts indicate at or above, not "at not below", there is a difference. David A Gubert
January 22, 201313 yr Just a note: the charts indicate at or above, not "at not below", there is a difference. In the UK they are "below". See GEN 2.3 http://www.nats-uk.e...&Itemid=10.html Gerry Howard
January 23, 201313 yr In the UK they are "below". See GEN 2.3 http://www.nats-uk.e...&Itemid=10.html Last time I checked Seattle wasn't in the UK and even if it was according to the document you linked to KARFO would be read as "Above 3200".
January 23, 201313 yr Commercial Member Just one example for KSEA ILS 16L. On Flightaware is says KARFO @ 3200ft but on Avivla EFB it says 1900ft. Thats a big hard alt difference! What's your navdata source and airac cycle? The last several cycles from Aerosoft for ILS16L have KARFO as "AT OR ABOVE 3200". (Each product functions in a fully-functional trial mode for interested users.)
January 23, 201313 yr I am using EFB, and I use fresh charts from Navigraph via their nDac3 application. I love EFB for several reasons, but the charts are sadly sometimes not up to date for some reason. Why I don't know, as you guys mention, they use Navigraph as a source, and I have the latest cycle installed in EFB. I have great hopes for EFB version 2, it has been planned for a long time.

January 23, 201313 yr .. according to the document you linked to KARFO would be read as "Above 3200". How do you read "below" as "above"? Gerry Howard
January 23, 201313 yr Commercial Member For me "not below"="at or above". Not sure what's the difference. In aviation, it's always about correct terminology. Effective and accurate communications (something often missing from pilots skills on VATSIM, but rarely ATC) help to ensure that ATC directives are heard and understood correctly, and to faciliate this the same terminology is used. Use the incorrect terminology (even if it means the same thing) would immediately be corrected by ATC to ensure safe and compliant operations. The same holds true when two aircraft with similar callsigns are in an airspace. To ensure safety, ATC would advise the aircraft that another aircraft has a similar call sign, so that neither pilot mistakenly performs the directive meant for the other aircraft. Charts too utilize set terminology. This helps to reduce mistakes. Hope this helps.

January 23, 201313 yr How do you read "below" as "above"? It looks to me that you are reading the "Minimum Obstacle Clearance" on Page 2. Try looking at Page 5. And don't tell me that's different because that is the SID and STAR symbols.
January 23, 201313 yr To make things easy, go to www.airnav.com look up the chart and it will be current. One good thing to remember is, it is a sim. Meaning the ground doesn't bite. If you fly the approach and make a good landing it will not matter what altitude your are at. The easiest thing to remember is fly the airplane to the ground. I fly a C750 which can be a handful if you forget the simple steps. Basics, we all learned to fly in a baby 150 or 175 and that was aviation at its best. When you add all the computers and bells and whistles it can overwhelm you. Make sure you altimeter is set prior to approach and fly the wires. Be easy on the throttles and controls and make very small adjustments to correct the wires. I use my everyday Jepps so I know they are current. I spend countless hours updating the charts in my bag. Happy flying. Any landing you walk away from is a good one. An instructor in the NAVY told me a landing is a controled crash. Nuff said, Cpt. McGill, R. J.
