Folks,
Where is a good place for the static port?
I ask because a Charger I’ve been looking at has two static ports, left and right side of the fuselage, vertically about 3 inches above the side panels hinge line, fore/aft pretty much even with the aft windscreen’s front edge. The owner says he thinks the airspeed reads 7-10 mph high, and the prop wash effect on the static ports is the culprit. That sounded plausible until I remembered that a Cessna 172 has static ports on the sides of the fuselage. Granted, they are up forward, ahead of the wing leading edge and about even with the lower front of the windshield, vertically about in the middle of that part of the forward fuselage.
I’m wondering if the airflow between the wings is the bigger influencer here, or maybe the erroneous airspeed isn’t static port location related at all.
And, while he didn’t mention it, if the static port location is the problem, the altimeter and VSI would also be erroneous.
Thoughts?
