    That's extremely interesting.  Your first two bombs never catch the laser and fall ballistically, as expected in an auto drop, and land about 7.5 miles short.  The other two do hit, and I can duplicate it now that I see how you do it.  I tried it at 25000, dropping one at 13 mi and a second at 12 mi (replicating your drop distances, using the same speed of 566 KTAS/.93M), and the first one runs out of energy and fall short, but the second connects.  I guess the parameters above were just a bit optimistic (that extra 4000' does help).  As others have pointed out, the GBU-10 should have the "bang-bang" flight controls, which one would think would bleed off the bomb's energy.  In any case, it's an interesting technique.  I never would have thought to use MAN mode like that.  We'll have to see what we can do with the Viper's MAN mode when it comes out.

    In the DCS Hornet, it is easily attainable for the GBU-10 in the following conditions:

    - level flight at 25.000 ft or higher;

    - speed roughly Mach 0.9 or above when release time;

    - target (naval vessel) stationary - 0 kts speed.

     

    I'd like to see a track of you doing this with a GBU-10 in the Hornet.  I've tried this multiple times just now with your parameters and get nowhere near the range that you claim you get.  At the range you say you're getting out of a GBU-10, the only thing that I am in range for is a GBU-38 at about 16 miles.  GBU-24 is max range at 9 miles, and GBU-10 and 12 command release at 5 miles and change.

  3. I don't find it particularly sluggish at proper aar speed (315 kn), as the power setting is high enough.  Part of the issue is the single engine nature of the viper, which is why it isn't as sensitive to throttle inputs as the twin-engine hornet.  I too find that I need a bit more physical throttle to produce as rapid a speed change as the hornet, but you don't necessarily want that when you're refueling.  As others have said, practice, practice, practice.  With more experience, you'll learn to anticipate throttle changes.  Also, zooming out a bit helps so you can see position/closure changes with your peripheral vision.  As for other possible reasons, what speed/altitude are you trying to refuel at and what stores do you have?

    If you mean they can't do instrument approaches down to ILS CAT I mins, you're correct no US fighter can. The A-10 specifically flies approaches to category D minimums.

     

    A point of order.  The aircraft category A-E on the bottom of the approach plate has to do with the aircraft's speed, not it's approach equipment.  The A-10 (and other US Fighters) absolutely can shoot CAT I ILS approaches because CAT I is the basic ILS, and said fighters have ILS receivers (though you are correct in that they do more VFR approaches than IFR).  You would be further correct if you were to say that those fighters could not shoot CAT II or III ILS approaches, as they aren't certified (though I would have to check their  -1s and vol 3s, to be sure).

  5. Even then, the bearing would be inaccurate.  Using the example above, after switching to North Up the bearing would indicate that the NDB/VOR was off the aircraft's right wing, when it would actually be off the aircraft's nose still.  I understand a few degrees difference for true vs magnetic (and I probably should've phrased my first post that way), but not moving at all around the compass rose just gives bad info to the pilot.  To be fair, though, I haven't shot an NDB approach in over ten years, so you may be right.  We'll see what the team comes up with.

  6. The ADF bearing circle on the HSI works fine in Track Up, but it doesn't follow the magnetic bearing when you switch to North Up.  Instead it maintains the same position on the outside of the compass rose.  I.e., if it is at the 12 o'clock position in Track Up flying west, it remains at the 12 o'clock position in North Up instead of moving to the 9 o'clock position to maintain the correct magnetic bearing.  Track attached.

  7. That's interesting.  With the flap switch in EXT I can't get much more than 6 g and change.  But with the switch in NORM I can get the full 9 g.  This is strange considering that in the external view the flaps indicate 6 degrees in both settings at high speed.  You may have stumbled upon a bug, although I guess you could be tricking the FLCS into an AoA limit.

    Sorry I didn't make it clear. Put it in EXT and at low speed that amount is adjusted automatically to a percentage. In my case that is near 6%

    For everyone's SA, they're at 6 percent in NORM, and as you slow they gradually lower if in EXT.  You would therefore have more lift while at a lower speed, so it makes sense that it would help turning.  As you accelerate, they come back up.  If you want them to stay at 6%, just leave the switch in NORM.

    I flew KC-135s in the USAF. Our TACANs for refueling are A/A only. And we only get distance, not bearing to one another. We certainly don't have a TACAN beacon onboard (like a ground based station). We just use the A/A feature of TACANs that allow us to see distance from our receiver (when set to 63 channels apart) and then use that data to make the rendezvous work.

    Good to see another TOAD.  I confirm this as a current 135 pilot.  If you want bearing AND distance, you need a KC-10 or KC-46, and it should be A/A.  The current reference is the ATP 3.3.4.2 US National SRD (publicly available at the Joint Air Power Competence Centre) para 4.17.3.

  10. Definitely unexpected behavior.  Even when lofting the aircraft, the missile seems to fly itself downward in a direct path to the target steerpoint if there's no line of sight from the aircraft to the target steerpoint, regardless of if the emitter is on the rwr.  However, when line of sight is established, the missile lofts normally.    harmLOStest.trk

     

    Edit: Just tried it with the Hornet and the same thing happened.  I can make a separate topic in the Hornet forum if you want @BIGNEWY, but it looks like this is a general AGM-88 issue.

    Apologies for Necroing this, but I have a question you might be able to answer. AA Tacan on tankers, is it just yardstick (range only), or do tankers have actual beacons onboard to give bearing too?

    Range only for the 135.  KC-10s have bearing and distance according to the SRD, but I've never flown on one.  As a practical matter, if you're flying something with a radar, that's what you're going to use anyway.  The only fighters that I remember using TACAN with us were A-10s.

    Have fun then in IFR with just Tacan, but it is not enough for IFR. You need that touch down point and TACAN is not accurate enough in fog.

    If the airfield is completely socked in, you shouldn't go there.  1000' ceilings are considered IFR conditions and a TACAN (or any other non-precision) approach is just fine for them.  Do answer Norman99's question, though.  What aircraft have you flown and how much time do you have in it/them?

    Although it may or may not be modelled correctly the real one has ILS the same as an Airliner. Hornets are an ALL WEATHER MULTI ROLE AIRCRAFT and have to operate in IFR conditions. They have to have ILS to be all weather. The real Hornet has ILS.

    Though you said it again, you're still wrong.  I'm guessing you don't have any real-world flight experience due to your lack of knowledge of other types of instrument approaches.

    In reality pre-connect PDL indications are directive in nature and I think fully manual in control. The directions would be based on your airplane type and rate of motion, "talking you on" with the lights. 

    Correct.  For example, at 10' from the contact position the boom manually flashes the forward light.  Other lights may be used for direction if EMCON does not permit a verbal correction.

  15. You're also pretty far right.  Try to stay under the centerline.  At the least, try to stay between the director light strips, that's +/- 2 degrees of azimuth.
