Sporty's Study Buddy prepares you for the FAA Private Pilot knowledge test (the "written") with three ways to study: Study Questions, Flashcards and Practice Tests. Questions are organized by knowledge area, with explanations of the right and wrong answers developed by Sporty's team of Master CFIs, based on their experience preparing students for the Private Pilot certificate. • STUDY QUESTIONS BY TOPIC • Choose whole knowledge areas or individual topics to build your own study session. As soon as you answer, you'll see the correct answer, why it's right, and where to read more. Change your answer anytime, bookmark questions as you go, and jump to any question from the question list. Every study session is shuffled. • REVIEW WITH FLASHCARDS • Flashcards show just the question, so you answer from memory before revealing the correct answer and its explanation. Mark each card Know It or Still Learning, then start a new session from the cards you're still learning. On iPhone Duo, study a card with the phone open and close it to check the answer. • TAKE PRACTICE TESTS • Each Practice Test draws 60 questions at random from the full question bank, gives you 2 hours, and is graded at the FAA's 70% passing score. Afterward, see your score by topic, review every question or only the ones you missed, and turn your misses into a new study session. • PICK UP WHERE YOU LEFT OFF • Sessions save as you go. The History tab lets you resume any session in progress and review past results, including your scores by topic. • EVERY FIGURE, OFFLINE • The Figures tab includes the complete FAA Airman Knowledge Testing Supplement, with every figure and legend listed by name and page. Swipe through the pages or open any one full screen. Questions show their figures right alongside, and you can study without a connection. Designed for iPhone, iPhone Duo and iPad, with Dark Mode and support for larger text sizes. The FAA does not publish its knowledge test questions, so the questions on your test won't necessarily appear in this app. Study Buddy is meant to complement your training, not to replace flight and ground instruction.

Gyronimo Performance Pad Piper PA 28-181 -Archer III- The ultimate computer for Mass & Balance and Performance. **** NEW: FLAPS UP takeoff distance computation **** Calculate and interpolate performance data using the actual values from the Archer III Pilot's Operating Handbook (POH). Finish your complete fight planning in just a few seconds. Performance planning has never been easier and quicker. Results are updated immediately and displayed in high resolution graphics, enhanced for the iPad Retina. Change all important values using sliders. Experiment with the results and create "what if" scenarios in no time. Find your optimal cruise altitude, takeoff ground roll, landing distance, climb data and stall speeds. The Performance Pad Archer III has seven main pages: 1. The Mass & Balance (or Weight & Balance) Page Calculates Center of Gravity, Moments, Takeoff and Zero Fuel Mass as well as Percent MAC (% MAC). 2. The Takeoff Page Using the actual data from the Operating Handbook the Performance Pad calculates and displays Ground Roll and Landing Distance based on: - Aircraft Mass - Takeoff Elevation in MSL (Pressure Altitude and Density Altitude will be computed) - Outside Air Temperature (OAT) - Altimeter Setting - Runway Conditions (i.e. paved dry to long grass or snow) - Runway Slope - Wind Conditions 3. The Climb page Calculates time, fuel and distance based on - Difference between Takeoff Elevation and intended Flight Level - Altimeter Setting - Outside Air Temperature (OAT) - Altimeter Setting - Headwind or Tailwind Component Also the Rate of Climb and Climb Speed will be displayed. 4. The Cruise Page Using the actual data from the Pilot's Operating Handbook you can determine the optimal cruise altitude based on - Trip Distance - Flight Level - Engine RPM - Temperature - Wind and Altimeter Setting 5. Landing Page Calculates Ground Roll and Landing Distance based on wind, elevation, altimeter setting etc. Like on the Takeoff Page you can use the Wind Components Computer to quickly determine head- or tailwind components 6. Stall Speed Page. Calculates The Stall Speed based on Bank Angle and Flap Settings. Stall Speed will be computed as KIAS and KCAS using the actual values from the POH. 7. Setup - Load and Save up to five Aircraft Settings and Scenarios. - Send a Mass & Balance Summary to your email address. - Visit our video channel and watch tutorials and video manuals. Mode Switch: The Performance Pad can be used in two Modes: "Individual Mode" All calculations can be done independently from each other. "Plan Mode" Calculated values will be forwarded to the next page and an additional "Flight Summary Page" is available. Choose this mode if you want to do a complete performance planning.

ReceptionRating · Positive reviews · Number of ratings

Piper Archer III Performance Pad holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Private Pilot Test Prep has 116 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 82% of Private Pilot Test Prep's written reviews are positive against 75% of Piper Archer III Performance Pad's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Private Pilot Test Prep ships an update every 5 months, Piper Archer III Performance Pad every 4 months. The most recent releases landed on October 30, 2026 and October 11, 2026 respectively.
