Are you a pilot learning a new aircraft type? Tired of just reading flipping through pages and pages of SOPs? And wondering if any of it is sticking... Always cramming right before recurrent? Learn and actually check your knowledge year round with SOPr. Practice on the crew bus, or waiting in the terminal. Create and share your SOPs, checklists, and flows. With Learn mode you go through the SOPs in sequence, and then guess the actions. Turn up the pressure in Quiz mode and be challenged with a random SOP, but don’t make a mistake or that list will reset and you’ll have to start from the beginning as your race against the clock. *For training purposes only.

This P-Star Study Guide app is designed to ensure that student pilots have the necessary knowledge in areas such as air regulations, navigation, meteorology, and general aviation. The app consists of 185 multiple-choice questions distributed across the following 14 topics: Collision Avoidance, Visual Signals, Communications, Aerodromes, Equipment, Pilot Responsibilities, Wake Turbulence, Aeromedical, Flight Plans & Itineraries, Clearances & Instructions, Aircraft Operations, General Airspace Regulations, Controlled Airspace, and Aviation Occurrences. Users can select a topic from the Practice Categories page, then go through each question in the category, selecting a response and being automatically presented with the next question. Upon completing a category, the user is presented with a summary page indicating how many of their responses were correct, how many were incorrect, and their percentage of correct responses. At the bottom of the summary page are three links: Review, which allows the user to go through each question to see the correct response; Retake, which resets the score and takes the user back to the first question in the category; and Topics, which returns the user to the Practice Categories page and displays a green check mark beside the category, indicating that it has been attempted. Note: Each of the question and review screens displays an Acronyms link that allows the user to reference descriptions for acronyms or abbreviations.
