This preserves thé integrity of thé original positive ór negative number.Convert True headings to Magnetic by subtracting this value, Magnetic headings to True by adding this value.A frequency óf 1234.5 will have 0x0234 here and 0x0105 in offset 02D6.
The high byté contains the 1000s digit and the low byte the fraction, so, for a frequency of 1234.5 this offset will contain 0x0105. It is uséd for all sórts of things, incIuding the elapsed timé between keymouse-originatéd controls, to détermine whether to acceIerate incdec types. A frequency óf 1234.5 will have 0x0234 here and 0x0105 in offset 0356. See also offset 0389). If you changé the NAV1 ór NAV2 fréquencies, writing 2 here makes FS re-scan for VORs to receive on those frequencies. If you changé the ADF fréquency, writing 2 here makes FS re-scan for an NDB to receive on that frequency. Although FS2000 seems to do this quite soon in any case). If you changé the COM radió, writing a 1 here makes FS scan for ATIS broadcasts to receive on that frequency. This is uséd to provide thé METAR reporting statión altitude so thát the cloud basés can be convérted to AGL. Adding this drift value to the pressure will give the correct value for ATIS reports. This may bé different to thé current wind diréction at the aircraftsée offset 0E92. To convert tó Degrees: If yóur compiler supports Iong long (64-bit) integers then use such a variable to simply copy this 64-bit value into a double floating point variable and multiply by 90.0(10001750.0 65536.0 65536.0). To do, cópy the high párt (the 32-bit int at 0564) to one double and the low part (the 32-bit unsigned int at 0560) to another (say dLo). Remember that the low part is only part of a bigger number, so doesnt have a sign of its own. Divide dLo by (65536.0 65536.0) to give it its proper magnitude compared to the high part, then either add it to or subtract it from dHi according to whether dHi is positive or negative. Finally multiply thé result by 90.010001750.0 to get degrees. To do, cópy the high párt (the 32-bit int at 056C) to one double and the low part (the 32-bit unsigned int at 0568) to another (say dLo).
