Lots of plane crashes?

[Noldorin]

I've been running the game for nearly 15 years (started 1950), and suddenly my planes has started crashing a LOT. I replace them but the new ones often crash within a year. The crash frequency has increased dramatically, and I don't see what is causing this. Sure, one of the crash sites (airport) lies next to a hill, but planes also crash where the airports lie at a high point in the terrain.

Any ideas? What determines if planes crash? My profit is now dropping fast as a result of this.

Are you using small airports? Some of the later planes cannot land safely at a small airport.

I'm using the early "DART" plane which takes 65 passengers or something like that. Since it's such an early model I suppose it should be able to use the small airports, but I'm not sure. The reliability of this model isn't very high, but they did not crash for several years, until now, when they have started to drop from the sky constantly.

Anyway, I'll try switching to more reliable planes and larger airports and see if the situation gets better.

Small Jet airplanes crashing nearly 90% when they are trying to land on small airports. The big jets 100%

reliability of a vehicle is related to when it was designed aswell as when it was built, so it might be that you need to use a newer type of plane, which would also mean upgradin to a larger airport.

I'm pretty sure the Dart plane is a jet-plane (or just a faster plane), and therefore unsuitble for small airports (512mph).

The reliability of this model isn't very high, but they did not crash for several years, until now, when they have started to drop from the sky constantly.

If what bobingabout post is true, the low reliability could be the reason. I'll take a look at the airplane source and see how landing is handled.

EDIT: Taken from airplane_cmd.c:

Code: Select all

prob = 0x10000 / 1500;
if (st->airport_type == AT_SMALL && (AircraftVehInfo(v->engine_type)->subtype & 2) && !_cheats.no_jetcrash.value) {
		prob = 0x10000 / 20;
	}

	if ((uint16)Random() > prob)
		return;

So, small airports do have a large effect on plane crashing, although I'm uncertain if reliability is in there somewhere - I'm would assume it's the engine_type or the subtype pointer.
