This is just a little piece of information I had in mind, and wanted to share, As we know, there are different types of Air Speed we use when flying an Aircraft; There is Indicated Airspeed, Calibrated Airspeed, Groundspeed, and True Airspeed.
-Indicated Airspeed: Is the speed Pilots use as a reference to operate the Aircraft, this is the piece of
information we observe when we rotate during takeoff, rise and lower Landing
gear, raise and lower flaps, expect a stall to occur at, etc.
-Calibrated Airspeed: Is the Airspeed corrected for installation and position error.
-Ground-Speed: Is simply put, the speed at which an aircraft flies in relation to the ground.
-True Airspeed: Is an aircraft's speed relative to the air mass it is flying in.
True Airspeed and Indicated airspeed will only be equal when flying at sea level in standard temperature and pressure.(We do not see this very often.)
True Airspeed of an Aircraft increases at a rate of 2% per 1,000 feet.
Which means, that at an altitude of 5,000', flying at 100 Knots Indicated Airspeed, our True Airspeed will be 110 Knots. So we might be crossing a runway threshold during landing at 100KIAS, thinking we have are speed nailed, when in reality our airplane is flying at a higher speed, which will result in longer landing roll distances. And who knows, maybe we are carrying a little extra speed for gusty winds, and maybe our runway isn't that long after all. we might find ourselves in a situation where safety might be compromised by a high speed approach during landing.
Once again, Thank you all for stopping by, and as you know I appreciate any kind of feedback.
