Pitot head

A long nose probe carrying a pitot head was added.

Never blow down the vents or the total energy and pitot heads because this can destroy the instruments.

These instruments operate by pressure lines from the Pitot head and static pressure sources.

The pointer responds to the dynamic pressure from the pitot heads on the nose compartment.

Investigators found that the pitot heads had ice damage which caused the crew to receive incorrect airspeed readings.

Pitot head cover removed.

This has to be corrected for Position Error (Static Pressure effected by movement of the aircraft in relation to the position of the Pitot head and static vents).

It took until November 1960 to recover most of the aircraft; the accident investigation concluded that the starboard pitot head had failed inflight, causing the flight control system to force the aircraft into an unrecoverable dive.

Things like coloured navigation lights on wing tips or on the pitot head, which is used for the measurement of airspeed and altitude and is usually mounted near the nose of the aircraft, can be good tell-tales.

Lift struts have a clear primary structural role but are sometimes also used to position devices like pitot heads and wind driven generators in a region of clear airflow, following the similar use of interplane struts in biplanes.
