  1. The Autopilot/Power Assist/SAS compensates ( driven by the gyros) for pitch, roll and yaw changes within certain air speed limits and/or pilot control inputs.

     

    However the SAS, as modelled, may have too much authority ATM and there may be changes in a future patch, following RL gazelle pilot feedback to improve the sim and/or explain some counter intuitive behaviour to players.

     

    Hope so... Can't imagine this is realistic given the sudden change in force balance and the compensating - rather than anticipating - nature of a gyro. Let me see what happens without the gyro/AP system turned on

     

    So I tried that...

     

    Looks like it has nothing to do with the SAS/AP system... Reaction to torque changes during forward flight is almost absent... should it be like this?

  2. Two Questions:

     

    1) Why is it that I don't need any left rudder input when I suddenly decrease the collective (or lose power)? The sudden main rotor torque change must affect the helicopter somehow... She now feels like an RC helicopter with a heading hold gyro.

     

    2) How/where do I select a radio to transmit over?

  3.  

    since the Mig-21 is equipped with a radar, does it also have auto release mechanism like the one found on the F-86?

     

    No.

     

    It allows for calculated impact point delivery of forward firing A/G ordnance (also works without radar turned on, which shouldn't be the case afaik). However, there is no calculated impact point for free fall bombs in any mode. (yet there is CCIP for bombs in the current version, that is I believe the point of the OP).

  4. No you can't use it for bombing realistically.

     

    In the real life you would take the bombing parameters from the table (which we don't have), adjust the gunsight elevation (which doesn't work) and try to fly the bombing profile manually as precisely as possible. Pretty much like it's done in the L-39, just faster.

     

    You can use manual mode to achieve that. Unfortunately in automatic mode there is still a CCIP solution that shouldn't be there. It should be exclusive to game mode.

     

    I bomb in manual mode and depress the pipper to the bottom of the ASP. I do not have any bomb charts though. I try to do steep dives and use the radar in fixed beam mode to get an idea of range to the target.

  5. Small inaccuracy

     

    (I glanced at the previous posts, I hope it wasn't mentioned yet)

     

    At the very beginning of the video in the original post, radar altitude shows 0. In DCS it shows 5, which I assume is the actual distance between the sensor and the ground. From the footage it appears that the offset due to landing gear height is taken into account...

     

    Easy fix I suppose. Just add an offset to the displayed Ralt. However, from an engineering standpoint, this offset should disappear when the landing gear is raised. Can't argue that from the HUD footage though...

     

    DCS 1.5.3 btw

  6. In the store page says minimun Ram for Nevada is 8GB.

     

    True

     

    Check out Matt's computer specs in his signature. Unless he upgraded and forgot to change his signature, Nevada will run just fine on 8Gb. Although he doesn't fly in multiplayer servers with 20+ players...

  7. The black sea map in dcs is completely flat, not round like the actual world. So everything is stretched.

     

    Yes that could explain the difference! I didn't know that the Caucasus map in DCS does not follow an Earth ellipsoid model. I always assumed it did, maybe because you can select an ellipsoid model in the Ka-50's ABRIS. That must have been purely cosmetic. It is a real shame that real world navigation aids don't work. I hope this will be different for future maps!

  8. Try to subtract 6°

    There is a difference between heading in map and magnetic heading

     

    No this has nothing to do with Magnetical variance. I'm taking map coordinates and compare them. Everything is in reference to true North.

     

    Besides differences are irregular and more significant than that, especially at shorter distances.

     

    And please read the part about the 20nm offset between DCS and real world coordinates. That alone rules out anything that has to do with the Magnetical North.

  9. Hey,

     

    I've made a simple tool in Excel to aid in navigating DCS modules that have no advanced navigation systems such as the Huey and the Mig-21. You enter the coordinates of your waypoints in decimal degrees and the tool automatically calculates (1) distance between waypoints; (2) initial bearing; (3) final bearing; and (4) straight-to heading.

     

     

    Distance is calculated using the haversine formula:

     

    a = sin²(Δφ/2) + cos φ1*⋅ cos φ2*⋅ sin²(Δλ/2)

    c = 2 ⋅ atan2( √a, √(1−a)*)

    d = R ⋅ c

     

    Initial bearing was calculated using the following formula:

     

    θ = atan2( sin Δλ ⋅ cos φ2*, cos φ1*⋅ sin φ2*− sin φ1*⋅ cos φ2*⋅ cos Δλ )

     

    wherein,

     

    φ = Latitude

    λ = Longitude

    R = Earth's Radius

     

     

    I noticed that there is a large discrepancy between calculated bearing and bearing as indicated in the DCS mission planner or on the F10 map. Distances also show a significant difference with DCS calculated distance, whereas the haversine formula should perform well even at meter-scale distances.

     

    After ruling out the possibility that my calculations were wrong, I simply took the coordinates of a random point on the DCSW map (Novorossiysk airport) and entered the coordinates into google maps. Guess what? In reality, this point is located 20nm to the southwest.

     

    So for your information: refrain from using real world navigational tools in DCS (or tools that are based on real world navigation, such as my tool). And for ED: please correct this.

  10. If you like the BAE Systems Hawk and you haven't been to RAF Valley (EGOV) in North-Wales yet, you must sure plan a visit! I have taken these pictures on the 22nd of July. It was very busy. At one point there was a formation of 4 doing an overhead break, while a helicopter was on final and two Hawks were awaiting departure.

  11. After about 20 takeoffs and landings, I find it pretty easy.

     

    I closley monitor the turn indicator on both takeoffs and landings. It warns me in which direction the plane is going to turn. I correct with rudder (or diff brakes on landing) accordingly to prevent escalation.

     

    Video of a short circuit, including takeoff and landing (I actually had a small emergency, but later it appeared that the button to start recording actually turned off the fuel pump :lol: :music_whistling:)
