Main functions: • Distance, flight time and estimated fuel used computation It will be based on the following parameters: - Mach number or TAS - ISA deviation - Distance factor to compensate great circle distance - Manual Wind component (Flight Ops Standard) - Automatic Historical average wind component (Flight Ops Pro) • Aircraft Profiles You can easily create and manage your aircraft profiles, setting the following: - Fuel used depending on distance flown. It can be set for as many distance values as you wish. The more you indicate, the more accurate will be your result! Of course, it can be done for any Mach or TAS - Structural weight limitations - ACN/PCN values In a single tap, you can even share these profiles via Airdrop, email, WhatsApp, Wechat, Dropbox... An example of aircraft profile with full instructions is provided in the app • Alternate airports finder It’s based on the following parameters: - Distance from destination - Minimum runway length - Paved runways or not - Airports of entry or not - Including military airports or not They will be automatically sorted by ascending distance from destination airport • Plotting map On this map you can plot: - Great circle routes between airports - ETP circles based on a specific radius - By a long push on the map you can display all airports around, making easy and fast the selection of ETP airports. As for alternates search, this selection is based on same parameters (see above) • Airports database - You can search in the database and retrieve any airport(s) based on the following parameters: ICAO code, IATA code, airport name or city name - Database can be updated (Flight Ops Pro) • Fuel uplift module You can use your aircraft limitations or use the "Free mode". If you fly different birds, your aircrafts limitations can be stored in the database. Therefore, no need to remember the max fuel weight or volume nor your maximum ramp weight! Based on your aircraft limitations, you can easily compute the fuel quantity required. Just enter desired uplift fuel volume, fuel weight or your desired aircraft ramp weight and Flight Ops will compute other numbers at once! It considers all common units: - Weight: Lbs and Kg - Volume: Liters, US Gal, Imp Gal - Density: Kg/L, Kg/US Gal, Kg/Imp Gal, Lbs/L, Lbs/US Gal, Lbs/Imp Gal You cannot get the fuel density from the fueler? Now you can retrieve it from the fuel temperature and can even select the type of fuel (Jet or Gasoline). • ACN / PCN Based on a PCN number, Flight Ops will decode and display a full description. If you have at least 1 aircraft in your database, it will provide your limitation(s) if any: - Aircraft weight - Main Landing Gear tire pressure - Nose Landing gear tire pressure If you indicate your aircraft weight, Flight Ops will compute your ACN. Of course, all these ACN values can be set through your aircraft profiles. • SNOWTAM decoding (METAR format) Just make a copy paste of any SNOWTAM or simply use the wheel. You will then get: - Full decoding - Wind components based on the related runway • Weather and airports information - You can build your own favorite airports list to check weather status at a glance - For any airport, you can get the latest METAR and/or TAF (if available) - Based on current wind speed and direction, Flight Ops will display all runways with corresponding wind components • Distance calculator To calculate the distance and True bearing between 2 latitudes/longitudes waypoints. • Last Minute Change Based on the Weight & Balance Load Sheet computed for your flight, grab your iPhone/iPad and compute your Last Minute Change data if necessary. Indicate your new payload, adding or removing pax & cargo and update your fuel values if required. Flight Ops will then calculate revised weights and centers of gravity for ZFW, TOW and LDW.

=== NaviGuard === An Innovative Flight Safety Feature for Pilots and Operators In today's world of advanced technology and GPS-dependent navigation, pilots and flight operators need a reliable solution to ensure the accuracy and safety of their flight paths. Aircraft Performance Group is proud to offer NaviGuard, a unique feature designed to enhance the navigation capabilities of our flight planning applications. NaviGuard is specifically developed to help users avoid reported areas of GPS interference, detect anomalous GPS readings on their iPads, and validate GPS data using radio navigation. This feature offers pilots improved safety and precision during planning and in flight. == KEY BENEFITS OF NAVIGUARD == -- ANTICIPATE PROBLEMS -- Real-time monitoring of problem areas, enabling pilots to foresee and circumvent issues stemming from GPS spoofing and jamming before they occur -- SET ACTIVE ALERTS -- Proactive in-app notifications that alert pilots of known danger zones during flights, presenting the option to reroute or proceed with complete awareness of potential hazards. -- PLOT & CONFIRM -- In-flight GPS coordinate verification by mapping relative to Navigational Aids (NAVAIDs), removing any uncertainty about location accuracy.

Verdict
The clearest difference is rating: NaviGuard at 5.0 against Flight Ops's 4.3. NaviGuard also leads on in-app purchases (none vs 2) and review sentiment (100% vs 77%). Flight Ops's advantage is update cadence (weekly vs every 2 months) and ratings volume (27 vs 2). On price and ads 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
Both are free to download. Flight Ops sells 2 in-app purchases, starting at $8.99 per year. NaviGuard asks for nothing beyond the download.
NaviGuard holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Flight Ops has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 77% of Flight Ops's written reviews are positive against 100% of NaviGuard's.
Flight Ops ships an update weekly, NaviGuard every 2 months. The most recent releases landed on October 5, 2026 and October 14, 2026 respectively.
