Q:
Are you aware of the fact that the Speed Gauges in almost every planes indicate 5% - 15% too slow speed?
I´ve been doing some tests for navigation. Basically I wanted to figure out the time I have to fly for a certain distance.
So I did this test in FMB (no wind, 100 meters hight):
Time: 3 minutes (0.05h)
Speed: 250 Km/h IAS
(on this low alt and speed TAS/IAS shouldn´t make a big difference on a regular day I suppose)
So after the math is done (250km/h x 0.05h) the flown distance should be exactely
12.5 Km
I did the test several times with several axis planes and everytime the actual flown distance is
14,5 Km (that indicates a speed of somewhere around 285 Km/h).
Tests from other players had been done and the result is that speed gauge from Spit indicates even 15% too slow speed and Me109 about 5% too slow speed.
->
If a Spit and a Me109 fly at the exact same (indicated!) speed, say 250Km/h, they don't fly the same distance in the same time!!
