DmitriKozlowsky Posted June 7, 2021 Posted June 7, 2021 Thats when it me, that in low viz weather with new clouds, new low clouds, that I have no clue on how to recover F-5E in IFR weather. TACAN can guide you to the field, but not down to it in IFR. F-5E was used over Vietnam and Thailand, so recovery in bad weather had to be the norm. We dont have military precision approach radar to guide us down. So is VFR landing the best we can do in DCS: F-5E?
some1 Posted June 7, 2021 Posted June 7, 2021 (edited) Although F-5 does not qualify as IFR platform in a modern civilian meaning of this world, you still can perform a non precision approach. System limit for VOR/DME approach is 250 ft, though typical MDA (minimum descent altitude) or OCA (obstacle clearance altitude) for such approaches in real world is usually calculated to be around 500ft above ground or more. Which means you should be able to see the airport no later than when you are at 500ft AGL and you cannot descent further without runway in sight. You fly the published approach profile, which gives you certain altitudes at certain distance from the airport, and also includes a chart which gives expected rate of descend and time it takes to fly between fixes at various speeds. Problem is, approach charts are not included in DCS and the airports and navaids in DCS may not match the real world. But you can find the real world approach charts for the airports that exist. For example here is an approach chart for Kutaisi VOR/DME RWY 07 https://airnav.ge/eaip/2020-09-24-AIRAC/graphics/UGKO-IAC-07-VORy.pdf And other charts for this airport. https://airnav.ge/eaip/2020-09-24-AIRAC/html/eAIP/UG-AD-2.UGKO-en-GB.html Edited June 7, 2021 by some1 2 2 Hardware: VPForce Rhino, FSSB R3 Ultra, Virpil WarBRD, Hotas Warthog, Winwing F15EX, Slaw Rudder, GVL224 Trio Throttle, Thrustmaster MFDs, Saitek Trim wheel, Trackir 5, Quest Pro

I did have this problem as well and I love flying the F-5 in bad weather since it is very immersive and realistic! If there are no procedures, I've designed a let down which works with basically all TACAN equipped aircraft/airfields. Edited June 10, 2021 by bbrz 8 i7-7700K 4.2GHz, 16GB, GTX 1070

charliefox2 Posted June 11, 2021 Posted June 11, 2021 TO 1F-5E-1 details instrument approaches with diagrams on pages 2-19 thru 2-22 (TACAN, radar, VOR, and ILS approaches). I know linking manuals is dicey on this forum; not quite sure what the rules are about screenshots from them (probably the same), but a quick google search shows somebody has uploaded it to the DCS user files so it should be pretty easy to find.
wraith70 Posted June 11, 2021 Posted June 11, 2021 Here's a mission I fly to practice IFR with TACAN approaching Havadarya. You could make a mission at any airfield because we have a portable TACAN unit now. Reaper guy did a video on it which gave me the idea: https://www.youtube.com/watch?v=O8ZPRcPD8_E NAV - IFR TACAN Bad Weather Landing 0600hrs Havadarya.miz 1
AH6OY Posted August 10, 2021 Posted August 10, 2021 If there's an in game NDB next to the intended airport you can make your own non precision approach. Fly over the beacon at a back azimuth of the airfield go out a minute on that bearing then 45 degrees for a minute keeping heading by adjusting for wind for a minute then make a 15 degree banked turn for a 180 turn. Once completing the 180 start letting down.This heading you stick to for a minute watching for the beacon to be at the runway heading which will be at 45 degrees when you get there. Plan your let down so it works out good for getting down. FAA is picky about the decision height but I don't think they'll mind you busting an altitude. I figure it will work unless the F5 doesn't have ADF nav gear. If waypoint's are available set waypoint's to use and assign yourself altitudes. If lucky you can be your own FAA
DoorMouse Posted August 10, 2021 Posted August 10, 2021 Thats the neat thing... You dont. Its not an IFR rated aircraft. It is an actually challenging thing to do. Best thing to do is use Tacan and fly by instrument. Hope there are no mountains
Baltic Pirate Posted August 19, 2021 Posted August 19, 2021 F5 did come with an ILS receiver. Most of the newer ones have it, especially the model we have. It would be a nice addition to DCS. ADI had FD needles making flying an actual approach a lot easier. 1

If lucky you can be your own FAA The F-5E-3 doesn't have an NDB compatible ADF, only TACAN and the ADF set of it's UHF radio. So to answer the OP, you can make a TACAN approach, but for our aircraft the best thing would be a PAR approach. The only problem is PAR isn't implemented beyond eye-candy of PAR vehicles like the RSP-7 [NATO: "Two Spot"].

If there are no procedures, I've designed a let down which works with basically all TACAN equipped aircraft/airfields. Not too shabby. Now we tend to use the 3 rule a lot. 9nm 3000ft, 6nm 2000, 3nm 1000 and so on. Same thing really. You also need to maintain constant speed and constant ROD to stay on the imaginary glide path. Say 165 KIAS, assuming it is the same as your GS. Easy calculation: 5x 165 = 825 fpm ROD should keep you on path. This is close enough unless you have really strong winds. Works in real life and DCS is well enough simulated for real life formulas to be applied here.
