Quick Start: Plan Your First Flight in 5 Minutes
This guide assumes you're a pilot who knows what a navlog is and has filed flight plans before. If you just want to see how IN-FLIGHT works, follow along with the example route below.
Example Flight: Islip to Hartford (IFR)
We'll plan KISP → KBDL via J-route with STELA ONE arrival.
Step 0: Install as Web App (Optional but Recommended)
For the best experience, install IN-FLIGHT as a Progressive Web App (PWA):
iOS (Safari):
- Tap the Share button (square with arrow)
- Scroll down and tap "Add to Home Screen"
- Detailed tutorial
Android (Chrome):
- Tap the three-dot menu
- Select "Install app" or "Add to Home Screen"
- Detailed tutorial
Desktop (Chrome/Edge):
- Look for the install icon (⊕ or computer icon) in the address bar
- Click it and confirm installation
- Detailed tutorial
Benefits: Faster launch, full-screen mode, works like a native app, better offline experience.
Step 1: Load the Database (One-Time Setup)
Before planning any route, you need the airport/navaid database:
- Click DATA tab
- Click LOAD DATA button
- Wait ~10-30 seconds for download
- Confirm you see database stats (70,000+ airports, 10,000+ navaids)
This is a one-time step. Data is cached in your browser—even works offline afterward.
Step 2: Enter the Route
Click ROUTE tab and enter:
Filed Route:
KISP APE EWC ETG J217 HNK STELA1 KBDLWhat this means:
- Depart KISP (Islip/Long Island MacArthur)
- Via APE, EWC, ETG waypoints
- Fly J217 (jet route) to HNK (Montauk VOR)
- Arrive KBDL (Hartford) via STELA ONE arrival
Enter it like this:
- Departure:
KISP - Route:
APE EWC ETG J217 HNK STELA1 - Destination:
KBDL
Hit COMPUTE.
What happens:
- App expands all intermediate fixes on J217
- Auto-expands STELA1 STAR with appropriate transition
- Calculates distance/bearing for each leg
- Applies magnetic variation (WMM2025)
You should see a green success message and waypoint count.
Step 3: Add Aircraft Performance (Optional but Recommended)
Scroll down in the ROUTE tab and expand "Wind Correction & Time":
For a typical light single (C172, PA28, etc.):
- Cruise Altitude:
9500(IFR eastbound) - True Airspeed:
120knots - Forecast Period: Select based on your departure time
Click COMPUTE again.
What happens:
- App fetches winds aloft from NOAA for your altitude
- Calculates wind-corrected headings and ground speeds
- Estimates time en route for each leg
No internet? You can manually enter winds in the NAVLOG tab later.
Step 4: Add Fuel Planning (Optional)
If you want fuel calculations, expand "Fuel Planning" in ROUTE tab:
Example for C172:
- Fuel Capacity:
40gallons - Fuel Burn Rate:
8.5GPH - Reserve Fuel:
5gallons (45 min VFR, adjust for IFR) - Starting Fuel:
38gallons (if not full)
Click COMPUTE again.
What happens:
- Calculates fuel burn for each leg
- Shows fuel remaining at each waypoint
- Warns if you don't have enough fuel + reserves
Step 5: Review the Navigation Log
Click NAVLOG tab.
You'll see a table like this:
| Waypoint | Type | Freq | MC | Dist | GS | ETE | Fuel |
|---|---|---|---|---|---|---|---|
| KSFO | APT | — | — | — | — | — | 38.0 |
| GROVE | FIX | — | 232° | 12nm | 118kt | 0:06 | 37.2 |
| BSR | VOR | 114.8 | 141° | 97nm | 125kt | 0:46 | 30.7 |
| ... | ... | ... | ... | ... | ... | ... | ... |
What to look for:
- MC (Magnetic Course): Heading to fly (wind-corrected if enabled)
- Dist: Distance from previous waypoint
- GS (Ground Speed): Accounts for wind
- ETE (Estimated Time En Route): For each leg
- Fuel: Remaining at each waypoint
Click airport codes to open AirNav for runway/frequency info.
Step 6: View the Route on the Map
Click MAP tab.
You'll see your route plotted on an interactive map with:
- Departure and arrival airports (blue/green markers)
- Route line connecting all waypoints
- Zoom controls (ROUTE, DEST, 50NM, 25NM)
To enable GPS tracking:
- Click "Enable GPS" button
- Grant location permission in browser
- Your position appears as a cyan aircraft symbol
- Distance/bearing to next waypoint updates live
Step 7: Fly the Route (GPS Tracking)
GPS is automatically enabled when you grant location permissions. The map shows:
Moving Map Features:
- Auto-waypoint advancement: App automatically switches to next waypoint when you pass within ~2nm
- TTS announcements: Optional voice callouts ("Approaching APE, next waypoint EWC, heading 075")
- Haptic feedback: Device vibrates on waypoint passage (mobile devices)
Navigation Panel (left side):
- Shows next waypoint
- Required magnetic heading
- Distance and time remaining
- Current ground speed
- GPS accuracy
Quick Diversion:
- Click any airport on the map
- App instantly computes direct route with fuel/time
Step 8: Export Your Flight (Optional)
After landing, go to DATA tab:
- Click "Flight Tracks" section
- Your flight is automatically saved
- Click "Export" to download GeoJSON
- Import into Google Earth, ForeFlight, or other tools for post-flight analysis
VFR Example: San Francisco to Half Moon Bay
For a simple VFR flight, the process is even easier:
ROUTE tab (traditional mode):
- Departure:
KSFO - Route: (leave blank for direct)
- Destination:
KHAF - Click COMPUTE
Or use waypoint-only mode (faster):
- Departure: (blank)
- Route:
KSFO KHAF - Destination: (blank)
- Click COMPUTE
Both methods produce the same result!
Add winds manually in NAVLOG tab (if no internet):
- Click "Add Wind" button
- Enter altitude, direction, speed (e.g., "3000ft, 280°, 15kt")
That's it. Print the navlog or keep it on your iPad.
Common Workflows
Practice Building IFR Routes
IN-FLIGHT's autocomplete helps you learn route construction:
- Type departure airport:
KBOS - Type SID name: Start typing
SSOXS→ autocomplete shows PAYGE - Type last SID fix:
SSOXS - Type airway: Start typing
V3→ autocomplete shows airways from SSOXS - Type next fix: Start typing on V3 → autocomplete shows only fixes on V3
- Continue building route...
- Type STAR:
LENDY6 - Type destination:
KLGA
Result: KBOS PAYGE SSOXS V3 SAX J57 LRP LENDY6 KLGA
Analyzing Routes from Other Sources
Got a route from ForeFlight/FltPlan? Analyze it in IN-FLIGHT:
- Copy route string from your EFB
- Paste into IN-FLIGHT ROUTE tab
- Hit COMPUTE
- Compare navlog distance/times to understand the route structure
Useful for learning how routes are constructed.
Comparing Altitudes
Want to see how winds affect different altitudes?
- Enter route with altitude
7500, click COMPUTE - Go to NAVLOG, note total time and fuel
- Go back to ROUTE, change altitude to
9500, click COMPUTE - Compare NAVLOG results
Learn how altitude selection affects flight time and fuel burn.
Pre-Loading for Offline Use
Going somewhere with no cell service? Pre-load your route:
- Plan route while connected to internet
- Load winds aloft (automatic if connected)
- Install app as PWA (browser prompts, or use browser menu)
- Route data is now cached offline
- Turn on airplane mode → app still works
Great for remote airports or in-flight use.
Tips for New Users
Route Entry:
- Quick entry: Just type waypoints in the Route field (first = departure, last = destination)
- You can use
DCTfor direct routing:KSFO DCT KOAKmeans direct from SFO to Oakland - Separate waypoints with spaces, not commas
- Airport codes can be ICAO (KSFO) or IATA (SFO)—both work
- If route won't compute, check for typos in waypoint names
Winds Aloft:
- If automatic wind fetch fails, enter winds manually in NAVLOG tab
- You can enter multiple wind layers (3000ft, 6000ft, 9000ft) for better accuracy
- App interpolates between altitudes for climbing/descending legs
GPS Tracking:
- Works best on mobile devices (phone/tablet)
- Desktop GPS accuracy depends on WiFi positioning (less accurate)
- You must grant location permission in browser settings
- For best results, use tablet with cellular GPS (even without SIM)
Fuel Planning:
- "Reserve" means fuel you won't use (VFR: 30-45min, IFR: 45min-1hr+)
- App warns if fuel remaining drops below reserve
- Fuel calculations assume constant power/mixture—adjust in cruise
Database Updates:
- Data from OurAirports and FAA NASR (periodically updated)
- Not AIRAC-cycle certified
- Always verify critical data (frequencies, runway lengths) against current charts
