Aspen

[mbmaksymdc10]

Aspen is a great piece of avionics but like most  avionics equipment today when it is touch by a  shop  for almost any reason 

for sure can count on trouble 

last time a IFR test was done aspen was off by 15 feet tech tried to adjust couldn't get it so repeatedly turned aspen on and off and finally 

poof no more display answer was will equipment can fail at any time
