kontiuka Posted March 8, 2015 Posted March 8, 2015 I set my min altitude to 2000 ft. At a zero degree pitch angle, the min alt carat is centered at exactly 2000 ft. At a 5 degree pitch angle, it is centred at 2020 ft. At a 10 degree angle, 2050 ft. Just wondering why it changes with pitch angle.
TIMBER SOUR Posted March 8, 2015 Posted March 8, 2015 The Gun MRS is based upon relative TIME, unlike the CCIP MRS which is based on an absolute ALTITUDE. The top of the Gun MRS represents -5 seconds from the set MIN ALT based on current aircraft motion, while the bottom of the scale represents +5 seconds from the set MIN ALT. Therefore, at any given altitude, you will see different MRS indications depending on aircraft vertical velocity.

But I would have thought that when the carat is dead centre, then you are at the minimum altitude. This only appears to be the case at a zero dive angle.
TIMBER SOUR Posted March 8, 2015 Posted March 8, 2015 The DCS manual contains contradictory statements regarding the Gun MRC. On one hand, it says that the MRC indicates when "recovery must begin", while the illustration depicts a centered MRC as meaning the aircraft is "at minimum recovery altitude". Those two things are different when the aircraft vertical velocity is non-zero. In order not to penetrate the MIN ALT set in the 30mm menu, you will need to begin recovery prior to MIN ALT if you are descending. The amount of altitude lost during recovery varies according to dive angle, thus at greater dive angles recovery must begin sooner. The Gun MRC symbology reflects this by displaying a time-to-go until recovery must begin. Just imagine if you were shooting a 60 degree High Angle Strafe with a MIN ALT of 500ft. The MRC would allow you to kill yourself if it didn't take into account the vertical velocity.
