TAS cannot be determined for aircraft not transmitting heading information

[aqagha]

Hello,

I recently encountered and aircraft transmitting TAS information in mb[25:35] with an all-zero mb[14:24]. TAS determination was blocked by this statement.

Would it be logical to move this statement to the subtype check beneath it?

pyModeS/pyModeS/decoder/bds/bds09.py

Line 38 in 89e67fa

if common.bin2int(mb[14:24]) == 0 or common.bin2int(mb[25:35]) == 0:

Thank you @aqagha. This has been fixed in the latest commit. Let me know if it works for you.

Hello,

It has taken me a while to pick up a transmission similar to the one before. I've received a few messages which are breaking at line 69.

One troublesome message: '8D7785649940000018A00054AA87'.

What could be the reason behind aircraft sending such messages only encoding vs?

Thank you
