Hi Hardy,

Here is a link for the Cloudahoy format:

Thanks for looking into doing this.

Hi Mark,

what parameters do you need?

The following is a list of recommended, but not mandatory, columns. If the data is available, it is used by the Analyzer. Otherwise the Analyzer computes the values.

    degrees/HDG
    degrees/MagVar
    degrees/Pitch [nose up => positive value]
    degrees/Roll [roll right => positive value]
    degrees/Yaw [yaw right => positive value]
    degrees/TRK
    degrees/WndDr [true direction] and knots/WndSpd
    fpm/VS
    feet/ALT (baro)
    fsd/HCDI and fsd/VCDI [values -1..1]
    g/normAcc [in m/sec^2]
    knots/GS
    knots/IAS
    knots/TAS
    Engine data such as n/E1 RPM, degreesF/E1 EGT4, percent/power, degreesF/TIT1 and others
    Control surfaces and gear position, such as degrees/flaps and down/gear.

E.g. if I include degrees/Lat and degrees/Lon, the Analyzer can compute ...
    degrees/TRK
    knots/GS
... on its own and so I need not include them.

E.g. if I include feet/ALT (GPS), the Analyzer can compute ...
    fpm/VS
... on its own and so I need not include them.

What's "fsd/HCDI and fsd/VCDI"? Is it horizontal CDI and vertical CDI? ILS needles?

Hardy,

I'll leave it up to you on what to include since those are optional fields.  My best guess is to include as much as possible from PSX to accurately map the flight path.

I am not sure what the HCDI/VCDI refer to so they can be left out.

Thanks.

4 seconds is the typical frame rate of flight data recorders (crash recorders). Within a frame, a variable may/will repeat a lot faster, so 4 seconds should not be the minimum resolution for true analysis. It may be that you hit upon a limit for the free demo? Just guessing.

Does anybody know CloudAhoy's Lat/Lon negative/positive setting?

North and east in positive numbers?

Hardy,

Here is an example file from a Garmin G1000, Cloudahoy accepts this format.

Thanks, Mark.

I just need to know this:

E.g. is 45 North to be entered as -45 or 45?

E.g. is 120 East to be entered as -120 or 120?

It's not documented on their web site, as far as I can see.

Is your sample file a flight in the USA?

Edit: OK, it's KBED ... so north positive and west negative.
