Distances

1 NM = 1,852 km
1 NM = 6080 ft
1 m = 3,28 ft
1 statute mile = 1,609 km

Weight

1 kg = 2.205 pounds

Volume

1 US-Gal = 3.785 L
1 Imp-Gal = 4.546 L

Pressure

Standard Pressure = 1013.25 hPa
1hPa = 27ft

Sphere

Big circle: 1° = 60NM

Speed

ICE-T
- Indicated Airspeed
  - ↓ correct for instrument error
- Calibrated Airspeed
  - ↓ correct for compressibility (negligible below 200kts and 10.000ft )
- Equivalent Airspeed
  - ↓ correct for altitude and non-ISA temperature (~ +2% for each 1000ft
- True Airspeed

Altitude

Indicated Altitude (set to QNH)
Pressure Altitude (set to 1013.25)
Density Altitude (corrected for temperature)
True Altitude

Q-Codes

Altimeter settings
Code	Meaning
QNH	Atmospheric pressure at mean sea level (may be either a local, measured pressure or a regional forecast pressure (RPS)). When set on the altimeter it reads altitude.
QFE	Atmospheric pressure measured at the airport station. When set, the altimeter reads the height above the station. Not in common use.
QNE	Indicated altitude at the landing runway threshold when 1013.25 hPa or 29.92 inHg (atmospheric pressure at sea level in the International Standard Atmosphere) is set as altimeter setting.
(QFF)	Atmospheric pressure at a place, reduced to MSL using the actual temperature at the time of observation as the mean temperature.

Radio Navigation
Code	Meaning
QDM	Magnetic bearing to a station
QDR	Magnetic bearing from a station
QUJ	True bearing/track to a station
QTE	True bearing/track from a station
QFU	Magnetic bearing of the runway in use
QDL	Series of bearings taken at regular intervals
QGE	Distance
QTF	Position in relation to a point of reference or in latitude and longitude
