Re: Europa-List: Pitot Static

Jim,
Were you having trouble with the single pitot head on your wings 
readings?  Seemed OK when we flew, why not just follow suit.  We use the 
Gretz mount here and that puts the heated Angus type tube about 5.5 
inches below which is out of the turbulent layer and if placed near the 
trailing edge spar is nearly perfectly equal to the flow to the flight 
path.  If you place the tube at two inches I'm afraid that turbulence 
may give you some poor readings.

George Reed has the only Dynon Tube I've installed placed per their 
instructions within 10 inches of the leading edge if memory serves.  As 
you know the Dynon also has a "AOA" input and if I recall it was 
required to be at least 6 inches below the wing which gave good A/S at 
cruise, adequate low speed down to 70 but kind of fell off too slow 
starting at 60 Knots.  However the current XS and MG wing positions 
using any tube seem to work well averaging within about 3 knots at low 
speed and dead on at cruise.

Regards,
Bud

  We are planning to install a heated pitot static.  The mast is 2 
inches tall compared to the Europa supplied pitot which is 4.5 inches.  
Will mounting the pitot closer to the wing present any problems?  

  Thanks
