It's easy for one person to use without training or expertise in Flight Operations. I like it because of its simplicity/ease-of-use and how well laid out everything was when first launched! No real downsides though; however if there were any features missing from this product please let me know so we can add them as soon as possible! Also just recently upgraded our server capacity which has resulted in increased load times but not detrimental ones at all - no loss of service thankfully!! We've used other products throughout various companies (from aviation software providers) who required extensive training and personnel with multiple years experience using their systems. MyFlightData by far surpasses these efforts and provides us enough power to handle anything thrown our way now!
