E6B calculator
Aviation E6B calculator - speed, distance, time, wind, temperature, pressure.
Temperature
Enter a value in any unit - others will update automatically.
Altitude correction (QNH)
Enter one value (inHg, hPa, correction in ft or m) and press Calculate.
Pressure altitude
Enter any two fields, then press Calculate for the third.
QNH (altimeter setting)
QFE
Density altitude
Cloud base
TAS (true airspeed)
PA, OAT, CAS/IAS → TAS. Enter three of four, then press Calculate for the missing one.
Magnetic course
TC ± Var = MC (Var E ujemna).
Magnetic heading
MC ± WCA = MH (WCA L ujemna, R dodatnia).
Compass heading
MH ± Dev = CH.
True heading
MH ± Var = TH.
Wind - drift and GS
WD, WS, HDG, TAS, CRS, GS - enter four of six, then solve the rest (e.g. CRS and TAS → GS and HDG).
Wind components
Speed / Distance / Time
D = S × T. Enter two of three (in any units), then calculate the third.
Fuel - time - flow
Fuel = flow × time. Units: L, US gal, flow in L/h or gal/h.
E6B calculator online
An electronic equivalent of the classic E6B slide rule calculations helps with flight planning, navigation training and checking wind effect on route. This module lets you quickly compute time, speed, distance, drift and basic atmospheric conversions used in general aviation.
