pitot head การใช้

A long nose probe carrying a pitot head was added.
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.
Other improvements included automatic blower controls, cowl flaps, intercooler doors and oil cooler for the engine, spring tabs for the elevators and rudder, a completely modernized cockpit, a completely retractable tail wheel, and heated cannon bays and pitot head.
Tropicalising measures included the installation of an air filter and intake in the upper forward fuselage, just behind the engine cowling, and the L-shaped pitot head under the outer port wing being replaced by a straight rod projecting from the port outer wing leading edge.
