Enter as many aircraft as you like and set your own parameters! Incredibly detailed and sophisticated App with built-in error management. EASY TO USE - Ensure correct aircraft selected - Enter required ramp fuel - Enter remaining fuel - Press calculate! - Techlog and fuel chit entries will be displayed DATA RETENTION - Remembers information used - Allows subsequent data input verification, unlike a calculator UNLIMITED AIRCRAFT - Designed to allow entry of aircraft type-specific parameters for as many aircraft and variants as desired - Set default specific gravity for each aircraft for ease - Set a preference for Separate Tanks if your aircraft does not have a fuel totaliser to avoid mental addition - Elect to display 'FULL' on the fuel chit when the wing tanks are full or the actual value - Supports rounding for aircraft that refuel in 100 Kg/Lb increments when using a 3-tank arrangement - Add company-specific volumetric tolerances for each aircraft to verify fuel weight and/or volume is within prescribed limits - Only needs to be done once PICTORIAL - Once fuel requirements have been calculated, tap anywhere on the Fuel Chit section to see a pictogram of the aircraft showing fuel distribution in each tank along with total fuel required and total uplift required! VOLUMETRIC CHECK - If required, it is possible to check both fuel weight and volume are within set tolerance. ERROR MANAGEMENT - Guards against entry errors using aircraft data - Automatic Universal App. See Developer website. Designed for iPhone but works just as well on iPad.

Briefing What Matters. NOTIME is a pilot briefing app that helps professional flight crew quickly review operational information before the flight and in the air. It organises supported Operational Flight Plans (OFPs), including Lido, NavBlue, Jeppesen and Virgin formats, into a focused, easy-to-read briefing. Available detail depends on the source document. BRIEFING • OFP analysis and operational summaries • NOTAM filtering by route, airport and operational timing • Departure, en-route and arrival weather summaries • Contaminated runway detection (GRF / RCAM) • ETOPS and escape-airport awareness • Volcanic ash, space weather and operational cautions • Interactive route map and vertical profile • Customisable operational thresholds and crew notes • Professional PDF briefing export ROUTE BUILDER Start with a supported flight number, paste a route or import an OFP. Confirm your intended departure date and time in UTC. Flight lookup may use a previous flown track; a complete route is not available for every flight. Coverage limits and missing data are identified in the briefing. LIVE ROUTE ASSIST Follow the loaded flight on the Visual Brief map using Flight API positioning, or choose device GPS. Tap a mapped airport for current weather, suggested runway, runway length, approach aids and aircraft-to-airport distance. Advisory terrain bands highlight terrain above 10,000, 15,000 and 20,000 ft. DIVERT Tap a supported airport to review applicable NOTAM restrictions by severity, with source text available for reference. FTL CHECK Enter duty details to review maximum FDP, latest on-blocks and available commander's discretion, including augmented crew, split duty, standby call-outs and delayed reporting. PRIVACY Core OFP analysis happens on your device and the complete OFP is not uploaded. Online route and weather services receive the details needed for your request. Flight API mode sends the loaded flight identifier to NOTIME's position service. Device GPS is used only when selected. Optional anonymous app-use analytics are off by default and controlled in More. IMPORTANT NOTIME is a supplementary briefing and situational-awareness aid for qualified flight crew. It does not replace the official OFP, approved charts, company procedures, dispatch information, ATC or pilot judgement. Live data may be delayed, incomplete or unavailable and must never be used as the sole basis for navigation, diversion, approach or landing decisions.
