As mentioned previously, the spawned aircraft are given a direct line of flight to the U-boat by the code before they are visible from the U-boat. This makes them deadly. The scripted aircraft can fly in a straight line past your U-boat without seeing it, even if it is close, unless the U-boat is by chance almost directly ahead of the flight of the aircraft."
from here.
Combine this limitation with the one causing an aircraft many times to not release its bombs/depth charges on the first pass (and being wildly inaccurate when it does) and one gets an aircraft "threat" that, isn't.

Hi John,


several years ago I made some tests concerning the 'blind' aircrafts. IIRC, there is no fundamental/hardcoded problem but only a sensor problem. It's much too insensitive for aircrafts.


According to my understanding of how sensors work in SH3, the game calculates every time interval of 0.?s for each sensor a probability that you are detected. This probability is determined according to a formula with parameters specified in sim.cfg. It then generates a random number and decides whether you have been detected, i.e., it's a nice 'Monte-Carlo' experiment.


Since an airplane has roughly 10-20x the speed of a ship, it spends less time in the region around a u-boat with a significant probability for detection. As a consequence, the total probability of being detected (not the probability in every single 'experiment') is much lower because the 'dice' is thrown less often for the plane.



My guess is that the devs didn't do a proper normalization of the probability to take the different speeds into account and thus fast objects have a disadvantage.


Best, LGN1
