4. DME SLANT RANGE VS. GROUND DISTANCE
5. TRUE AIRSPEED (TAS) VS. INDICATED AIRSPEED (IAS) AND ALTITUDE
Table II-4-1-App A-1 gives the true airspeed in km/h and Table II-4-1-App A-2 gives the true airspeed in kt at
temperature ISA + 15°C including correction for the compressibility effect. For calculation formula, see 6.1 of this
attachment.
Note.— These tables are only to be used in the construction of holding areas.
