Question: What is the potential impact of an uncoordinated turn on altimetry and indicated airspeed?
Answer options:
- It will cause the altimeter to under-read and the airspeed to over-read. ✅ It can lead to a slip or skid, producing erroneous indications on the altimeter and airspeed indicator due to disturbed airflow over the static ports.
- It will result in a constant over-reading of both altimeter and airspeed.
- It has no significant impact on altimetry or airspeed, primarily affecting turn coordination.
Correct answer: It can lead to a slip or skid, producing erroneous indications on the altimeter and airspeed indicator due to disturbed airflow over the static ports.
Explanation: An uncoordinated turn (slip or skid) distorts the airflow over the static ports, which can cause erroneous indications on static-pressure instruments like the altimeter and airspeed indicator.
