June 9, 200718 yr Hello all,Have a niggler that I've been trying to find out about, basically where does the ils freq of a rwy at an airport come from? My understanding is that the freq used is taken by the navdata from the a/c, in my case I'm using flight1's ATR, so we'll say if I'm inbound ils rwy 28 at EIDW then the freq I put into the afds will be the freq listed in the navdata of the atr in this case 111.350. Obviously the default freq (in this case rwy 28 EIDW is 108.9 i think) is overrided by the fms data of the a/c? However what if the airport is an addon airport? Do addon airports dictate the freq or is it always the a/c?. Anyone make it clearer?George
June 10, 200718 yr It's coded into the scenery .bgl file. If you have an airport add-on, it's possible for that add-on to exclude the original navaid data and substitute its own. AFCAD files often do this, for example.The data coded into the aircraft's navdata is generally used for auto-tuning frequencies. It would be possible for the panel to synthesize a nav display using an internal database, but I don't know of any that actually do this, as it would not necessarily line up with the scenery in use.RegardsBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile Bob Scott | President and CEO, AVSIM Inc ATP Gulfstream II-III-IV-V Sys1 (MSFS20+24/XPlane12+11): AMD 9800X3D, water 2x240mm, MSI MPG X670E Carbon, 64GB GSkill 6000/30, nVidia RTX4090FE Alienware AW3821DW 38" 21:9 GSync, 2x4TB Crucial T705 PCIe5 + 2x2TB Samsung 990 SSD, EVGA 1000P2 PSU, 12.9" iPad Pro Thrustmaster TCA Boeing Yoke, TCA Airbus Sidestick, Twin TCA Airbus Throttle quads, PFC Cirrus Pedals, Coolermaster HAF932 case Sys2 (P3Dv5/v4): i9-13900KS, water 2x360mm, ASUS Z790 Hero, 32GB GSkill 7800MHz CAS36, ASUS RTX4090 Samsung 55" JS8500 4K TV@60Hz, 3x 2TB WD SN850X 1x 4TB Crucial P3 M.2 NVME SSD, EVGA 1600T2 PSU Fiber link to Yamaha RX-V467 Home Theater Receiver, Polk/Klipsch 6" bookshelf speakers, Polk 12" subwoofer, 12.9" iPad Pro PFC yoke/throttle quad/pedals with custom Hall sensor retrofit, Thermaltake View 71 case, Stream Deck XL button box Sys3 (DCS/P3Dv4/ATS/ETS): AMD 7800X3D, MSI MPG X870E Carbon, Noctua NH-D15S, 64GB GSkill 6000/30, EVGA RTX3090 Alienware AW3420DW 34" 21:9 GSync, Corsair HX1000i PSU, 4TB Crucial T705 PCIe5 + 2TB Samsung 970Evo Plus, TM TCA Officer Pack, Saitek combat pedals, TM Warthog, TM RS300 FF wheel/pedals, Coolermaster HAF XB case
