AircraftPower is an Aircraft Engine Performance App. It uses a standard reciprocating engine performance model to calculate and display the sea level and altitude performance of 74 normally-aspirated Continental® engines and 108 normally-aspirated Lycoming® engines. A graphic display shows the engine performance chart and illustrates the manual construction method for determining altitude performance that we learned in ground school (and promptly forgot). As the user changes the input values, using the sliders or the custom keypad, for manifold pressure (or % power), rpm, pressure altitude and outside air temperature, the power output and percent power (or manifold pressure required) are displayed, and dotted lines and colored dots in the graphic display follow the manual construction method. While the graphics aren't really necessary, they are instructive (and interesting) to watch. The user may choose english or metric units for altitude, altimeter setting, temperature, manifold pressure and power output (however, the graphic always uses english units), and may select default values for the inputs and the engine. The user can also choose to input the indicated altitude instead of the pressure altitude (the default), and choose to input the % rated power instead of the manifold pressure. If using the indicated altitude, an input window for the altimeter setting appears.

FlightStreamX wirelessly sends flight plans from your iPad's Electronic Flight Bag (EFB) to X-Plane on your desktop — instantly, over your local Wi-Fi network. SIMPLE WORKFLOW 1. Create a flight plan in ForeFlight or Garmin Pilot on your iPad 2. Tap Share and select FlightStreamX 3. Your flight plan appears in X-Plane automatically No cables. No USB drives. No manual file copying. Just share and fly. HOW IT WORKS FlightStreamX automatically discovers X-Plane running on your local network using the X-Plane beacon protocol. Once connected, it converts your EFB flight plan into X-Plane's native FMS 1100 format and transmits it directly — all in under a second. SUPPORTED EFB APPS • ForeFlight (.fpl flight plan files) • Garmin Pilot (.gfp flight plan files) FEATURES • Automatic X-Plane discovery — no IP addresses to configure • Real-time connection status with host details • Instant flight plan conversion and transmission • Resend capability — retransmit your last flight plan with one tap • Dark, aviation-inspired interface designed for cockpit use • Shows route summary with departure, destination, and waypoint count REQUIREMENTS • X-Plane 12 or greater (desktop) running on the same Wi-Fi network as your iPhone or iPad • ForeFlight or Garmin Pilot with a flight plan ready to share • iOS 18.0 or later PERFECT FOR • Flight sim enthusiasts who plan routes on their iPad • Virtual pilots practicing real-world procedures • Anyone who wants a seamless EFB-to-simulator workflow FlightStreamX bridges the gap between professional EFB apps and desktop flight simulation, giving you the same workflow real pilots use — plan on the iPad, fly on the desktop.

Verdict
The clearest difference is review sentiment: AircraftPower at 100% against FlightStreamX's 0%. AircraftPower also leads on price (Free vs $8.99) and rating (4.9 vs 1.0). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
AircraftPower is free to download; FlightStreamX costs $8.99 up front. Neither carries in-app purchases, so what you see is what you pay.
AircraftPower holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: AircraftPower has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of AircraftPower's written reviews are positive against 0% of FlightStreamX's.
