Hello, dear ProfHoekstra, sorry to bother you. Instead of the Settings screen popping up when I opened BlueSky.py in Python, the following code appears Using Python-based geo functions Reading config from Reading magnetic variation data Loading global navigation database... Reading cache: C:\Users\23515\bluesky\cache\navdata.p Bluesky needs zmq Run setup-python.bat (Windows) or check requirements.txt (other systems) Install using e.g. pip install zmq BlueSky normal end. Process finished with exit code 0 Please give me some advice. Thank you again

Hi @gwt679,

Looking at the output you've included in your post you are missing one (or more) required packages (it mentions zmq).

An easy way to install all the necessary requirements for bluesky, run the following command from the root bluesky folder:

pip install -r requirements.txt

If you are on mac or linux you can replace requirements.txt with requirements-gui.txt. On windows there are issues with PyQt6 (which is installed with the requirements-gui list), which means you need to select the pyqt5 packages yourself:

pip install PyQt5 PyQt5-WebEngine pygame pyopengl

Hello, dear Professor jooste. With your help, I successfully installed the software. Sorry for replying you so late. During this period, I have studied the tutorial again, and I plan to reply to you uniformly if I have any questions.

The first problem was: I copied the code on the Wiki and pasted it into command. Nothing valid can be done after that (the enter key is invalid). Can I only enter commands manually by myself?

The second question is: when I use the command dtmult 10, speed: 6.4x is displayed. When I use the command dtmult 20, speed: 6.5x is displayed. May I ask what the reason is?

Thank you again for your help to me. I wish you a good health and a happy life.

What do you mean by this exactly? Which part of the wiki are you referring to, and what do you mean by 'the enter key is invalid'? You can manually enter commands, but you can also create and load timestamped scenario files.

The second question is: when I use the command dtmult 10, speed: 6.4x is displayed. When I use the command dtmult 20, speed: 6.5x is displayed. May I ask what the reason is?

Fast-time running will only go as fast as your computer can cope with. If you are for instance running a simulation with many aircraft it can be that only a small multiple of real time is possible, or even only running slower than real time.

Hi @gwt679,

The check.py error you can ignore, it uses a check that was removed in Qt6.

The RTree message at the start of bluesky indicates that you don't have RTree installed. By default it is not used in the simulation, so this also shouldn't be a problem for you. It is there for simulation setups with large numbers of polygons (urban environment simulations), and the plugins to use these data. In normal simulations, poly data is accessed through dicts, which works fine without rtree.

I'd like to ask you a few more questions; ① Can the conflict criteria be changed in settings.cfg? (such as horizontal distance, vertical distance, etc.) Because different regional conflict definition is different ② detailed plane plan of the airport. I found that some airports have very detailed plans, some airports only have one runway. Can I get the detailed airport plan I need?③ How do I get the climb profile of the aircraft flight path. Sorry to bother you again, please give me some advice in your spare time. Again, my respect to you.

[jooste]

Hi @gwt679,

1) I don't see a KL205 in the scenario file you mention? Aside from that, BlueSky currently doesn't have a dedicated ground model, which might explain the things you are seeing 2) Some scenario files come from bluesky's predecessor, TMX. Not all TMX commands are available in BlueSky.

1) you can set the protected zone margins per aircraft with the ZONER and ZONEDH commands within the simulation. 2) You mean the visualisation of airports in bluesky? These data are taken from X-plane. There is an editor for the file format X-plane uses, so you could create your own layouts for airports you want to have added. 3)what do you mean? If you want to visualise the (historical) altitude of an aircraft you can use the PLOT command (PLOT alt).

[ProfHoekstra]

By the way, taxiing should work nevertheless. But the performance is not very realistic, as the performance models do not have a ground model, friction etc is also not modelled.

Also note that some of the scenarios have been made with different performance models for the airborne part, which means the "open-loop" descents now have a different angle, resulting in a steep descent or landing short.

hi @jooste Thank you again for your great help. I'm a beginner. My goal is to use blue sky to simulate standard departure procedures at a specific airport. I need flight data throughout the flight. I encountered the following problems. ① I want to show the flight profile. 'synatax error: variable plot not found' occurs when I use the 'plot plot alt' command. I have 'plot' in python. Why does this problem occur and how do I solve it? ② Can I import the online map in blue sky as the background map ③ Where can I retrieve the flight data (altitude, speed, heading, etc.) during the whole flight

Thank you for your help. Have a nice life.

[jooste]

For sake of completeness:

• The plot command is called as: PLOT [state to plot], so e.g., PLOT alt
• You can use tiled maps from ao. OpenStreetMap using the TiledMap renderer in bluesky. Enable it with VIS MAP TILEDMAP
• You can create loggers that generate CSV log files using the CRELOG command:
• CRELOG TESTLOGGER 1
• TESTLOGGER ADD lat, lon, alt, trk
• In plugins you can access all state variables by importing the appropriate object (e.g., bluesky.traf)
