Landing Rate addon

Postby RenanMsV » Sat Oct 14, 2017 3:43 pm

FlightGear Landing Rate addon
Show your landing stats. Depending on your rate of descent on touching the ground it rates your landing as Excellent, Good, Acceptable, or Bad.

Image

Requirements

FlightGear 2017.3.1 version.

Install Procedures

Unzip landing_rate folder to any place you want. e.g C:\Users\USERNAME\Documents\FlightGear\Addons\landing_rate
Then add this command line to your FlightGear Shortcut :
--addon="C:\Users\USERNAME\Documents\FlightGear\Addons\landing_rate"
Note that this command line must have the correct path to the landing_rate folder. Do not know how to set command lines? Check here: http://wiki.flightgear.org/Command_line

Dealing with errors

Since each plane are different, for now 90% of aircrafts are compatible. If you're using an incompatible aircraft a message will be show. And the addon will be shutdown.

Share stats at mp chat

If you want, you can activate it. And a message will be sent by multiplayer chat showing your landing stats.
To enable it go to landing_rate folder and open config.xml. Find sharemp line.
Code: Select all
<sharemp>0</sharemp>

Change sharemp value ( 1 for yes and 0 for no ). Restart your simulator. Done.

sorry if I have missed it, but you may want to post a download link !?

Hi there,

not sure if you are already aware of this, or possibly even using it already, but regarding the issue of supporting aircraft-specific settings, I'd suggest to check out Stuart's checklist system, which can provide many aircraft specific configuration details (think V speeds) using the underlying XML file setting up the checklist system:

http://wiki.flightgear.org/Aircraft_Checklists
Image

A typical file would look like this: https://sourceforge.net/p/flightgear/fg ... klists.xml

Speeds can be seen here: https://sourceforge.net/p/flightgear/fg ... .xml#l2108

To process such files, you only need to use io.read_properties(): http://wiki.flightgear.org/Nasal_librar ... ties.28.29

props.nas contains a getValues() helper method which can return a whole XML file as a single hash-map: http://wiki.flightgear.org/Nasal_librar ... lues.28.29

PS: rleibner has been working on a GCA addon, which simulates ATC-controlled approaches providing vertical and lateral guidance - and it features a built-in approach profile display using the Canvas system, which may be something you may find useful to visualize the flown approach when rating landings:

Really good to know. I'll take a look.
But for now, my addon only uses current indicated-speed-fpm to rate landing. Really simplistic.

Okay, regarding a V-speed based implementation, you could check out the following wiki articles and code snippets implementing a similar system for copilot announcements:

http://wiki.flightgear.org/Aircraft_speed#V_speeds
http://wiki.flightgear.org/Howto:Calculate_V-speeds
http://wiki.flightgear.org/Howto:Implem ... ouncements

IF you know a little about Nasal coding, this should be straightforward to come up with a V-speed based version for evaluting/rating landings.

For additional inspiration, you could take a look at the so called "redout" system, which also accessing g-force/acceleration properties: https://sourceforge.net/p/flightgear/fg ... redout.nas

This looks cool, but how can a landing G-Force to be 0.9?

Since part of the aircraft weight is carried by lift, the force the landing gear has to supply can be close to zero - or if you smash the aircraft into the ground, the acceleration can be several gravities.

Hi,

I made a little change[1][2][3] to the add-on API. The add-on framework now works with addon-config.xml instead of config.xml and addon-main.nas instead of main.nas. This is required in the current development version of FG, and will be required in the upcoming FG 2018.1. So, if you work with FG from 'next', you have to do these two renamings.

Sorry for the inconvenience. Regards

[2] FlightGear commit da961b97f
[3] FGData commit c17d9377f

Hi All,
For those interested in practising landing, I have updated the landing_rate addon on GitHub to make it compliant with file naming convention of more recent versions of FG (2017.3, 2018.1)
the updated GitHub repo is there : https://github.com/pascal-olin/landing_rate
All credits remain to RenanMsV
Have fun, and please let me know if it works off the shelf for these recent version for you too

Thanks
