Tiger4-2 Posted April 20, 2020 Posted April 20, 2020 Is compass deviation modelled in this aircraft? I've been flying Navy aircraft from the time period and there's usually a deviation card mounted somewhere, and I haven't seen one in the P51 cockpit. Thanks! Sent from my SM-G973U using Tapatalk
grafspee Posted April 21, 2020 Posted April 21, 2020 I think P-51 uses radio compass. System specs: I7 14700KF, Gigabyte Z790 Aorus Elite, 64GB DDR4 3600MHz, Gigabyte RTX 4090,Win 11, 48" OLED LG TV + 42" LG LED monitor
saburo_cz Posted April 21, 2020 Posted April 21, 2020 The P-51 does not use radio compass... (here in DCS or in ETO during WWII) The DCS P-51D does not have such equipment... In DCS W, gyro compass shows azimuth related to True North and magnetic compass shows azimuth related to Magnetic North. Magnetic Deviation on Normandy map is nearly 8°, and you will see that variation between them is nearly 8°...

Magnetic Deviation on Normandy map is nearly 8°, and you will see that variation between them is nearly 8°...I should have clarified. What you're thinking of is magnetic Variation, often called declination. I'm referring to the difference between a magnetic heading and what is indicated by the compass in the aircraft. The short and simple version is that the metal in the aircraft causes the compass to pull a couple of degrees at certain headings. It's different for every aircraft, and usually magnets were placed in different places around the cockpit to help. Usually you would have a card in the cockpit that listed the deviation for headings. It would look something like: For 000 steer N For 040 steer 042 For 060 steer 061 And so on. The mustang uses a remote indicating compass in the left wing, so I guess my question was whether this solved the problem of compass deviation and if not, if deviation was modeled at all.

grafspee Posted April 21, 2020 Posted April 21, 2020 So gauge number 2 what is it then ? System specs: I7 14700KF, Gigabyte Z790 Aorus Elite, 64GB DDR4 3600MHz, Gigabyte RTX 4090,Win 11, 48" OLED LG TV + 42" LG LED monitor

saburo_cz Posted April 21, 2020 Posted April 21, 2020 @Tiger4-2, you mean "compass error". I think, cosidering that this number is mainly unique for every plane, you dig too deep. :) F6F P-51D | P-47D | F4U-1D | Mosquito FB Mk VI | Spitfire | Fw 190D | Fw 190A | Bf 109K | WWII Assets Pack Normandy 2 | The Channel | Sinai | Syria | PG | NTTR | South Atlantic F-4E | F-14A/B | F/A-18 | F-86 | F-16C | A-10C | FC-3 | CA | SC |

grafspee Posted April 22, 2020 Posted April 22, 2020 (edited) I started to read about compass in p-51, As i see it P-51 don't have magnetic compass. Looks like P-51 uses Directional gyro.I am assuming that as name indicates it uses gyro to maintain fixed orientation in space. That means no errors, at least not magnetic related.

saburo_cz Posted April 22, 2020 Posted April 22, 2020 No.1 is magnetic compass sensor.

grafspee Posted April 22, 2020 Posted April 22, 2020 No.1 is magnetic compass sensor. But it has directional gyro too, System specs: I7 14700KF, Gigabyte Z790 Aorus Elite, 64GB DDR4 3600MHz, Gigabyte RTX 4090,Win 11, 48" OLED LG TV + 42" LG LED monitor
