Inspecting an air data probe for physical degradation includes generating a silhouette of the air data probe based on an identification of the air data probe to be inspected. The silhouette is simultaneously displayed with an image of the air data probe produced by a camera, and the displayed image of the air data probe is caused to conform to the silhouette on the display. An image of the air data probe is captured while the displayed image of the air data probe conforms to the silhouette on the display. The captured image is analyzed to identify physical degradation of the air data probe. A maintenance recommendation for the air data probe is generated based on the identified physical degradation.

Image-based inspection for physical degradation of an air data probe

A method of isolating a source of an altitude split in a plurality of altitude sensors includes receiving a static pressure reading from a first altitude sensor and receiving a static pressure reading from a second altitude sensor. The method also includes comparing each of the static pressure readings with an expected static pressure value to determine which of the altitude sensors is the source of a split in altitude readings of the altitude sensors.

Fault isolating altitude splits

An air data probe includes a probe head. The probe head defines a longitudinal axis with a forward tip and aft base and includes a wall tap port inlet defined in the probe head aft between the forward tip and the aft base. The wall tap port inlet opens on an angle relative to the longitudinal axis, wherein the wall tap port inlet has an elongated inlet perimeter configured to resist the formation of a meniscus, or otherwise reduce moisture induced pressure errors.

Moisture resistant air data probes

The invention provides a probe for an aircraft including a strut having an interior passage accommodating a plurality of pneumatic lines, a probe head extending from the strut and having at least one inlet opening communicating with the pneumatic lines, a baseplate situated below the strut for attaching the probe to the aircraft, and a manifold situated below the baseplate for communicating with the pneumatic lines, wherein the baseplate is adapted and configured so that the pneumatic lines communicating with the manifold are thermally isolated from the baseplate. The invention also provides a method of thermally isolating at least one pneumatic line in an aircraft probe.
