Hello there Reader,
I'm a bit fuzzy on something from the dark ages, back when one studied Flight Planning and Meteorological subjects.
Hopefully someone closer to the subject might be able to help.
You land at a sea level aerodrome where the barometric pressure is 975Hpa, and the ambient temperature a bracing 4 degrees C.
Not a biggie, but what's the density altitude correction for the temperature variation?
Thirty feet per Hectopascal for pressure variations to 1013, but what of temperature variation from ISA?
Sorry to bore you all, and yes I have sought assistance from the considerable efforts of Mr John Tullamarine's most useful references, all to no avail.
The Standard Atmosphere link was interesting, John.
Not sure about what all those results mean though.... :hmm:
Thanks in advance.
PS Was it something like 320'/degree?
