The difference between total pressure and static pressure is measured using portable airspeed indicators.
A pitot tube placed near the airstream’s stagnation point measures the total (or measured) pressure, which is then carried by a hose to the airspeed indicator.
It is also possible to connect a static pressure sensor. Hysteresis (differences between advance and return movement) and secondary elastic effects are hardly noticeable because the measurement element is an open diaphragm unit with outstanding elastic qualities.
A linkage and gear system transfers the diaphragm’s deformation, which is brought on by the effects of total pressure and static pressure, to the pointer.
Colour-coded markings on the airspeed indicator dial help to distinguish the aircraft’s various operating ranges. The instruments are not susceptible to vibration or stress.
The operating ranges and limiting performance of the aircraft can be indicated by colour marks on the instrument scale.
Only the airspeed indicators with colour marking on the indicator scale are compatible with the type series numbers listed in the aforementioned table.
The aircraft’s technical documentation should be used to find the part number in all other circumstances.
Global portable airspeed indicator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Belite Aircraft, a leader in ultralight aviation and avionics, has created an air computer that enables experimental and homebuilt aircraft to easily adopt new digital instrumentation.
In a very compact design, the air computer gives the pilot essential flight information. Additionally, Belite’s instrumentation now offers multiple functionality on a single device.
Examples include putting a vertical speed indicator (VSI), an air speed indicator (ASI), or an above-ground altimeter (AGL) together on one instrument.
A dual VSI/ASI, VSI/AGL, or an AGL/VSI are the outcomes of this. Additionally, Belite now has twin CHT/EGT gauge combinations, a Positive/Negative G Meter, dual Fuel Gauge, and much more.
The new instruments come in two standard sizes: the current 1.75″ square and the 2.25″ circular configuration.
Indicator for dual air speed. This novel instrument outputs a digital altitude and concurrently displays an ASI using the Belite Air Computer.
The 1.75″ square and 2.25″ round models come in performance ranges of 28-82MPH. The 2.25″ round type is also offered in the 35-135 KIAS range.
This can display rates up to 1500 FPM, depending on the model. A digital LCD display may be connected to the unit’s Altitude output connection, which offers another feature.
Additionally, single display units with the same size gauges are offered for ASI.
