Joe Larussa Posted February 23, 2018 Report Share Posted February 23, 2018 Any of you G5 guys notice a difference in the ships airspeed indicator and your G5? Mine used to be dead on and now I'm seeing a variable difference of plus or minus 3-4 Mph. Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 23, 2018 Report Share Posted February 23, 2018 Sounds like a leak may have shown up recently? Would one instrument be more sensitive to the leak than the other? Which one is showing the slower IAS? Old mechanical or new electronic? Has the G5 started showing GPS ground speed for some reason instead of IAS? Pp thoughts only, not a mechanic.

Joe Larussa Posted February 23, 2018 Author Report Share Posted February 23, 2018 Seems like I just noticed it in the last few weeks. Going in for IFR cert tomorrow. 1 Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted February 23, 2018 Report Share Posted February 23, 2018 Mine is dead on. I installed it as a HSI, but sometimes I put it in PFD mode and it is always dead on with both airspeed and altitude. Quote Link to comment Share on other sites More sharing options...

Mooney in Oz Posted February 24, 2018 Report Share Posted February 24, 2018 I have an Aspen and it has always indicated about 2 KIAS slower and 50-60 feet lower in cruise than the steam indicators. Quote Link to comment Share on other sites More sharing options...
jetdriven Posted February 24, 2018 Report Share Posted February 24, 2018 the POH shows that the IAS is about 2 mph faster than CAS at normal cruise speeds Quote Link to comment Share on other sites More sharing options...
Joe Larussa Posted February 24, 2018 Author Report Share Posted February 24, 2018 Passed IFR cert. No leaks. Tech says plus or minus three is within tolerance. Quote Link to comment Share on other sites More sharing options...
