Mbot Cockpit Altimeter 7000ft. Status Bar in external view 6585ft. So a diff of 415ft. Looking at Noodles error chart that would imply a Bomb around 100ft long. So in a 45 Deg dive it would seem the Alt lag is around 400ft. Weap manual gives 110ft Altimeter lag. That confirms your finding and also in my eye explains the impact points. Off to try releasing at 7400ft Alt :)

Yes MBOT on the cockpit Altimeter. Will record a Track to see what that is on the status bar. Noodle Ref Pilot errors. Thanks for the table ... Yep I am sure there are some in there (Been 30 years since I last dropped a manual bomb .... but it floods back :). Anyway I think I am getting pretty close to the planned release parameters I planned on. Bombs are all going pretty much in the same hole around 100ft over the top. if they were all over the place I would think it was me.

The carriers and certain other Navy ships should also have TACAN.

Did the numbers on 10 Deg High Drag pass Again pretty much all bombs hit around 100ft long. No allowance for Altimeter lag Same with 20Deg LD 2500ft release. Using calculated depression values all bombs hit around 100ft long. No allowance for altimeter lag. Taking around 20mills off the calculated figure results in consistently good bombs. Interestingly that is close to the AOA correction in the calculations.

Is this correct ? The MK82SE in game are depicted with both Nose and Tail fuses. If I only arm the Nose fuse the High Drag fins still open. I would have thought that if ONLY the nose fuse is armed the bomb would drop slick as the Arming wire to the Snakeye HD fin retainer would not have been energized so the wire and retainer would remain closed and go with the bomb so the bomb goes slick. JETTISON OF MK82SE INCORRECT Also If you are carrying MK82SE on the underwing pylons and press EMERG JETTISON button they also go HD on jettison. Again I don't believe this is correct as the Tail (and nose) fuse arming solenoids are not energized on jettison. So the Tail wires should go with the bomb the fins remain closed and no arming occurs.

Ok went back using 450KCAS as the release Air speed (to achieve 500KTAS) also decided to drop right on 7000ft ignoring the calculated Altimeter Lag (figuring maybe the Sim doesn't really have any) Still using 141mills. Much better bombs. Used the old airstrip on the coast just north of Batumi using the runway intersection as the aimpoint to get some yardstick. Got consistent bombs 1 runway width over the top. So roughly 50feet 12 O'clock bombs..... pretty good for 45deg 7000ft release. also pre trimmed nose heavy before the roll in. If I didnt do this the trim couldn't keep up with the change required going down the dive requiring forward stick to control the reticle drift up to the target. therefore in a slight bunt .... which would also tend to throw the bombs over the top. So WEAP manual ballistic tables seem ok to use in the SIM. Though I don't think Altimeter lag needs to be allowed for.

Err yes dumb error on my part will aim for slower release IAS (450) to achieve 500TAS at 7000ft

Been out there Practicing 45Deg High Angle Low drag all morning. Getting consistent hits with 100mils dep. This for 45 Deg 500TAS/7000ft Release. Roll in 14000ft 300Kias. Calcs from the weap manual shown below give dep of 141mils Off to try again.

Ok will try and replicate it in a track

Yep ok no need to upload :) I did some quick and dirty Calcs from the WEAP manual for a 45 Degree MK82LD release 500KTAS/7000ft release which is a pretty standard attack to keep out of the Small arms envelope (Vietnam era). Allowing for AOA (Flaps Auto) etc came up with 126Mills. Though Bomb impacts were reasonable all were over the top. For this type of delivery a Bomb inside 100ft of the aim point is quite a reasonable bomb. For Low Angle HD deliveries depression is going to be a lot more. I guess it just depends on how accurate the Ballistics of the bombs in DCS are to Real world ... and of course FM AOA etc.

I have an F5E/F Weapons manual happy to upload to the "User files" section of the DCS site if I could figure out how to do it ! Edit Figured out trying now to upload it. .... just says sending request but not sure if its actually going up ... not much seems to happen !

They wont be exact as ejection rack velocities from the PM3 and RPK10 on the Mirage will differ from those on the F5E. F5E Ballistic tables are floating around the net as an F5E/F weapon delivery manual

1. ADF is only usable for UHF DFing. So you would meed a UHF NDB in the tuneable range of the radio. Alternatively it can be used to "DF" a radio transmission on the tuned frequency. It cant be used like a conventional NDB/ADF combination.

Just had to give it a try :)

During ejection Northrop seat turns into ACESII seat :) (Just Ejection Graphic animation I think)

nope happening at meduim altitude with direct Line of Sight to the TACAN station

Thanks Eddie but I have been inside 25nm of the TACAN station. Will try turning dwn the TACAN Volume to see if it changes.

I don't see anything with the Landing lights they don't extend with Switch selected on and gear down.

Ah the joys of Manual depressed sight bombing ... sight handling is an art. In training you will notice where the Target sits reference things like the canopy rail. This then allows you to achieve a consistent dive angle regardless of your Base distance out. Of course you can only get so close as you need to allow for turn radius as well (Minimum Attack Perimeter MAP). So whilst on base establishing the correct relative position of the target sets you up to establish a reasonably accurate dive angle. A smooth roll in using Lift vector pointed to just above the target (dont dish the roll in) also helps in establishing the planned dive angle. On roll out you need to establish the correct Initial Pipper Placement (IPP calculated before flight) below the target. (The Flight Path is actually held at a point just past the target known as the Aim Of Point ... without a VV that is kind of nebulous ... that's why the IPP is so important). On Roll out note your dive angle (ADI/AH) ... if its not the planned dive angle then decide on a release altitude adjustment. If Steep then release slightly earlier than planned, if shallow then release slightly lower than planned (fingers in ears). Yugging to achieve the planned dive angle wont work ! ... accept the dive angle you achieve and adjust release height. Then as you travel down the dive try to hold the Flight Path on the Aim of Point just past the target. As you proceed down the pipper will drift up on to the target .... make smooth tiny bank corrections to dribble the reticle on to the target. Also monitoring altitude and IAS build up. You need to achieve pipper on AT the planned release altitude AT the planned release speed with the flight path on the Aim of point. Get them all right and a decent bomb will be the result. get any one of the wrong and bombs can go anywhere. As per dive angle corrections Airspeed errors can be compensated for by minor changes to release altitude. Though be super careful releasing low as you might bust the Frag envelope, run out of turning room and hit the ground, or release below the minimum height for fuse arming.

Something is wrong IMO on the logic behind the display of Ground clutter on the radar. Given the Antenna should be Earth/horizon stabilized, Pitch attitude changes (within limits) should not change the radar scan coverage. However if you vary pitch attitude with radar say 30deg up you can easily get ground clutter appearing at relatively low pitch attitudes.

Google found this :) http://forums.eagle.ru/showthread.php?p=2534793 As to only putting in TACAN's at real world locations, I don't think the ones we see in Georgia are real world ones.

I get a hissing sound in the cockpit that seems to come and go at random. It sounds almost as if the Squelch on the radio has been lifted. Cant see any pattern in it. Also if you go to external Fly by mode (F3) then jump back in the cockpit cockpit sounds are muted for quite a while. they eventually come back to normal.

not seeing this External transfer seems to be working normally for me. I started with 3 External tanks. Selected Inboard pylons initially. Roared around in AB. Left needle sat on 2000lbs, right needle on 2400lbs. after a while ext tanks empty light illuminated with light on caution panel. Left needle started dropping. Cancelled the light. Selected inboard pylons OFF and Cl on. Left Needle rose back up to 2000lbs. After a while EXT tanks empty light came on and left needle started dropping again. Turned off Cl then auto balance. So to me everything is working as it should.

Agree. I am using Crosswind pedals. For Rudder axis I use a Dead zone of 8 and a curve 30. NWS feels pretty right to me with what I recall IRL last century.

KUBAN/CRIMEA MAPS With more modules being released that incorporate realistic TACAN use could we get more TACAN stations on the map ? Ideally for all airfields. Ideally being hard coded for the map provides standardization for all users. PORTABLE TACAN These exisit and can be transported in by transport aircraft and set up fairly quickly (like in 24hrs). With this in mind it would be nice to have as a Mission object to allow Mission builders to drop in TACAN units on a need basis.
