IAS, TAS and Ground Speed & Descent Charts.

[Bluecat]

Hello every good man here,

I have take a look at some aviation books and i find that for the performance calculation, most of these books have attached with the takeoff, climb, en-route cruising and landing charts for calculation reference. However, in most case, i do not find any descend chart for the calculation, i wonder should i use the climb chart for descend calculation or is it because most books just has missed to mention it. Please give me some advice on this for every professional here, i will be very appreciate for any advice.

Happy New Year

Cheers,

Dear all,

In the flight log, it was found that there are IAS, TAS and Ground Speed. Would anyone told me their difference.

For the time calculation, time = distance/ speed, would anyone told me i should use the IAS, TAS or ground speed to calculate the time?

Thank you.

Cheers,

Bluecat

Use groundspeed.

TAS is IAS corrected for instrument error, compressibility and density altitude. Groundspeed is TAS corrected for wind.
