Virtual Flight Training, I don't want to be annoying but thanks for the like on my comment. I was wondering if my questions were inappropriate since you didn't reply, again thanks for your videos and have a great day!
yeah, sorry for that, I was dining out. Anyway, thank you very much for your comment, very interesting questions. In fact, the purpose of these videos is to differ from others in the right way! To your first question I basically answer yes, because when the "IR selector" (called in this way) are in nav position, they supplies full inertial data to aircraft systems. for the toliss on the other hand I didn't fully understand what you mean, don't they aligning on GPS? either way the airport reference coordinates are sufficient unless you want hight navigation performance ((i.e. if you have to fly without GPS with expected long segments in poor NAVAIDS coverage or if you perform low RNP operation). In this case you should adjust the airport reference coordinates to the gate coordinates with the slew keys.
@@VirtualFlightTraining Oh I'm sorry, I just thought you forgot or weren't able and wanted to make sure my questions weren't off, I'm sorry that you were dining. Thanks for the answers and yes, about the toliss I meant that, that they don't align in gnss automatically like here. I don't know if you know about the differences between the phone and plane accuracy because they make no sense to me. So when flying with IRS only I'll guess you'll have at least 0.3nn. anyways thanks for the answer and your patience. :)
@@anslucasi0980 no worries! for any doubt ask any question, this will also help others in this channel. honestly, i don't know too much the difference between the mobile gps or gnss, But I can tell you that on the a320 family, the two GPS receiver is integrated in a modular avionics unit called MMR (or Multi Mode Receiver). When the MMR can track 4 or more satellites, it enters NAV mode and continuously supplies data to the ADIRUs. additionally, the aircraft’s position is calculated by FMS computed position using Hybrid GPS/IRS position, GPIRS position combined to provide a MIX IRS position and from the radio position combined, if the two DME or VOR/DME are available. Probably, for short periods of time, the IRS is extemely precise, instead for long time, the GPS is more precise. that's why gps and irs are hybrids. so I'm not sure if the phone position is more accurate than an airplane, but maybe I'm wrong because this is off topic for me 😅 Hope it can help you
@@VirtualFlightTraining cool thanks! Well I mean right now inside my house I have an accuracy of 20 meters which would be around 0.01NM, and planes can and have more than that usually, I mean for an RNP approach you can have up to 0.3NM. I understand it's not a topic you know 100% about but I appreciate your answer as always, I didn't know all that theory btw! Thanks and have a great night.
@@anslucasi0980 got your point, the accuracy of an airplane degrades as it moves away from its initialization point, this is understandable in long leg that it is less accurate than a phone with gps. good night you too! 😄
Grazie del video !!!
Mi fa piacere, grazie a te ❤️
