A Little about IVAO
IVAO is about the same as Vat Sim except that there are less pilots flying and less controllers at any given time. Vat sim is much more controlled and strict than IVAO is. In the US there are very few controllers on IVAO. Most of the controllers are in Europe as IVAO is a Europe based Sim control group.
I have been a controller on both and from a controller’s standpoint IVAO is far better to control on than Vat Sim. Not near the rules. Not to say you can’t get into trouble on IVAO because you can. There are no costs for IVAO and very little training or testing to fly on IVAO. Same with controlling, you can be a controller on IVAO with a very small amount of training, but you are limited to where and when you can control until you have completed higher training.
If you wish to fly on a system where you can see other aircraft and fly with friends or as a group, then IVAO is the one to fly on. Also, if you like flying with very little in the way of controllers then IVAO is for you. On the other hand, if you want to be controlled during your flight then I would say to go with Vat Sim.
If anyone has any questions about IVAO and IVAO flying or controlling just contact me by email or on Team Speak.
