The Real Slim Shady - what your saying is that when temperature rises, density decreases, as does your thrust and lift. As far as TAS/IAS goes, as your density decreases your TAS is higher for a given IAS. Correct so far?
According to the sample RTOW chart (A319 w/ IAE2522s) given in the Airbus "Getting to Grips with Aircraft Performance" brochure, for a given wind component:
- V1 decreases with increasing temperature upto the thrust break temperature, where it increases slightly and then decreases again.
- VR behaves in the same way as V1.
- V2 continually decreases as temperature increases.
Can anyone explain this?
