What is the white arc?

The white arc indicates the flap operating range, VSO to VFE, used for approaches and landings. The yellow arc cautions that flight should be conducted in this range only in smooth air, while the red line (VNE) at the top of the yellow arc indicates damage or structural failure may result at higher speeds.

What does the white arc on an airspeed indicator represent?

WHITE ARC—This is known as the flap operating range, or the speed at which the aircraft can be flown with full flaps. The lower limit represents VSO, the stalling speed or minimum steady flight speed in the landing configuration. The upper limit represents VFE, the maximum speed with the flaps extended.

Who is LK Chen?

LK Chen produces faithful recreations of historical Chinese swords and weapons with highly precise blade geometry and balance. They take great efforts to adhere to the authenticity of a weapon and its particular historical era in order to produce the most accurate recreations available.

How does ASI work in aviation?

An air speed indicator (ASI) is a device for measuring the forward speed of the aircraft. The ASI uses the aircraft pitot-static system to compare pitot and static pressure and thus determine forward speed. In two pilot aircraft, each pilot has a similar ASI and each ASI is fed from an independent pitot-static system.

What is VS0 speed?

VS0 means the stalling speed or the minimum steady flight speed in the landing configuration. VS1 means the stalling speed or the minimum steady flight speed obtained in a specific configuration. VSR means reference stall speed. VSRO means reference stall speed in the landing configuration.

What is aircraft airspeed?

In aviation, airspeed is the speed of an aircraft relative to the air. True airspeed (“TAS”), equivalent airspeed adjusted for air density, and is also the speed of the aircraft through the air in which it is flying.

What is green arc?

Green arc – The Green Arc is the normal operating range. The very top of the green arc, is the maximum structural cruising speed, commonly known as VNO. Yellow arc – The yellow Arc is the caution range. The aircraft should not be flown in this speed range in rough air. The answer is 1.7 times the normal stalling speed.

Why do pilots say airspeed alive?

The pilot verbalizes “Airspeed Alive” as a reminder to verify that the airspeed indicator is working. If the airspeed indicator doesn’t show an indication that it is working, the pilot would typically abandon the take-off while still on the runway and get it fixed before flying.

Where is LK Chen swords located?

The sword you order is ship directly from our workshop in Longguan, China. LK CHEN SWORD DOES NOT CHARGE FOR SHIPPING, THE CARRIER DOES.

When was the Tachi invented?

First and foremost, it’s important to note that the tachi was invented before the katana. Historians believe that Japanese swordsmiths developed the tachi in the Koto period (900 to 1596), whereas the first use of the word “katana” didn’t occur until the Kamakura period (1185 to 1333).

Is IAS or TAS higher?

The IAS meter reads very nearly the TAS at lower altitude and at lower speed. On jet airliners the TAS meter is usually hidden at speeds below 200 knots (370 km/h).

What is a white arc in aviation?

White arc—commonly referred to as the flap operating range since its lower limit represents the full flap stall speed and its upper limit provides the maximum flap speed. Approaches and landings are usually flown at speeds within the white arc.

What is arc Blue Light whitening?

Using a specific blue wavelength, ARC Blue Light targets tough, set-in stains below your enamel’s surface, making ARC whitening more effective than strips alone.

Is white arc a real Han Jian?

White Arc is the quintessential single hand military Han Jian and based on a real Han Jian in LK Chen’s personal collection. White Arc exemplified the signature characteristics of Han Jian: an austere, long, slim, light and sharp single hand sword.

What technology does arcarc use to whiten?

ARC uses both whitening strips and LED Blue Light technology to get that little extra lasting boost of whitening.
