Specific Air Range (TAS / fuel flow)
To achieve the best possible SAR we need to get the best TAS / fuel flow ratio and as fuel flow relates to power we can also say TAS / power ratio.
TAS
True AirSpeed. The airspeed of an aircraft relative to undisturbed air

The movement of an airplane under its own power on the surface of an airport ...
TAS - True Air Speed. Because an air speed indicator indicates true air speed only under standard sea-level conditions, true air speed is usually calculated by adjusting an Indicated Air speed according to temperature, density, and pressure.
TAS.
True airspeed
Taut line.
Basic guidance mode; provides vertical guidance to maintain a taut line for a dipping sonar, or other such device.
TAS The speed of an aeroplane through the air in which it is flying
Thr Threshold

Standard rate turns are used as commonality in almost all instrument procedures and when pilots go to be instrument certified they must be able to perform a standard rate turn for the check pilot.
True airspeed (TAS) is the physical speed of the aircraft relative to the air surrounding the aircraft. The true airspeed is a vector quantity. The relationship between the true airspeed and the speed with respect to the ground (Vg)is:
Where: ...
True airspeed (TAS): Airspeed corrected for instrumentation errors and air density.
U/V ADF: UHF/VHF Automatic Direction Finding.
So, after allowing for vagaries in your heading keeping ability, the variations from your plot figures of TAS and wind speed and your invariable failure to apply the compass deviation shown on the card near your aircraft's compass (does anyone?), ...
Avidyne is upgrading their TAS-600/610/620 TCAS products to add ADS-B support, associating N-numbers and airline flight numbers with active targets.
IAS - indicated airspeed. An aircraft's speed through the air as indicated by the ASI, without correction for position error, altitude or outside air temperature. Also see CAS, RAS and TAS.
IATA - International Air Transport Association.
True Air Speed (TAS) - The speed at which an aircraft is traveling through the air.
