Route → ICAO syntax
Convert VFR reporting points and decimal coordinates to ICAO flight-plan tokens (DCT). IFR navaids are kept as published. Origin and destination ICAO codes are omitted.
Only validated ICAO tokens are included. Unresolved VAC points, unknown fixes, and invalid coordinates are omitted — see the panel on the right.

Climb distance & rate
3° climb rule of thumb: distance to level-off (NM) ≈ altitude to gain ÷ 300; climb rate (fpm) ≈ groundspeed × 5.
- Altitude to gain
- 5500 ft
- Level-off distance
- 18.3 NM
- Climb rate
- 350 fpm
- Climb time
- 15 min 43 s
Descent distance & rate
3° glide-path rule of thumb: start descent (NM) ≈ altitude to lose ÷ 300; descent rate (fpm) ≈ groundspeed × 5.
- Altitude to lose
- 5500 ft
- Start descent at
- 18.3 NM
- Descent rate
- 425 fpm
- Descent time
- 12 min 56 s
Wind correction
True course, TAS, and wind (from) → WCA, true heading, and groundspeed.

Fuel endurance
Endurance from fuel on board and burn rate. Reserve is subtracted for usable endurance.
- Total endurance
- 5 h 54 min
- Usable endurance
- 4 h 55 min

QNH ↔ altitude
Approximate correction using 30 ft per hPa (ISA). For planning only — verify with current altimeter setting.
Pressure altitude
2508 ft
Indicated 2500 ft with QNH 1013 hPa set
Rule of 60
1 NM off track at 60 NM flown ≈ 1° error. Correction (°) ≈ (off distance ÷ distance flown) × 60.
Track error / correction
+4.0°
2.0 NM off after 30.0 NM flown
