How to know the cruise speed?

<< < (3/3)

EHM-1077 Emanuele:
shift-z gives you the -true- airspeed (TAS),
while your panel is likely set to show
you the -indicated- airspeed (IAS).

Ciao ciao!

EHM-0962 Zhen Yi:
you can get your ground speed from the GPS system onboard! ;D

EHM-0001 Gergely:
Indeed, the ground speed is on the GPS.

Shift+Z and panel will display the IAS or the GS, depending on the setting in Realism settings (Show True Airspeed, Show Indicated Airspeed).

For more info about IAS/TAS check the VFA FAQ.

Also don't forget to start the Pitot Heat; if you don't, you'll get erroneus speed readouts.

EHM-1077 Emanuele:
Oooops. My mistake then.
I was totally convinced the setting would
affact only the speed on the panel, but
not the one with shift-z.

Sorry about that.  :[

Tried that too.. but for some reason I get a read 50 kts lower then what my panel says

That is because you have a head wind of 50kts. The speed show by the ADF is actual ground speed, the speed show by the aircraft is Indicated Air Speed (IAS). For instance, if you have an IAS of 100kts with a head wind of 20kts, your actual ground speed is 80kts. Hope that sorts things out for you.

Cheers
