must be assumed to be a TAS reading. The two owners mentioned above
found out the hard way that this is a fact.
How much difference is there between IAS and TAS in practical terms?
Data is for standard atmosphere. To obtain correct speeds for particular atmospheric conditions please
take advantage of the conversion tables which follow:
The table below indicates how fast you may fly at a certain altitude to maintain constant True Air Speed
(TAS).
The table below indicates how TAS increases with altitude while keeping IAS constant.
As you can see from the table above the differences between IAS and TAS are substantial at altitude, and
MUST be respected at all times!
REMEMBER!
Do not trust your ears.
Do not trust your eyes.
Trust the instruments and be aware of the IAS to TAS relationship!
Keep that in mind every time you go flying. Pipistrel wishes you happy landings!
Myth: One can fully deflect the controls as long as he or she is flying below maneuvering speed.
