B2B Verified

A major concern for companies conducting business through the Internet is to know that the company that you are in contact with and contemplating a deal with is authentic and credible. As a free service to our users, B2Brazil verifies certain members through its \"B2B Verified\" service. Members can become verified by either upgrading to B2B Verified status or becoming a Premium Member or Premium Plus Member. To become B2B Verified, B2Brazil authenticates and verifies that.

B2Brazil verifies that:

  • The business is legally registered
  • Contact information is confirmed

For a small fee, a user can request B2Brazil to gather additional authentication and verification information about a particular member(s). This information includes conducting a search with a relevant and independent credit agency (such as Dun & Bradstreet), conducting a search for any legal complaints, and retrieving company verification information based on the company’s tax ID number. For further information, contact us.

NOTE: B2Brazil verification does not guarantee business credibility, and B2Brazil assumes no liability for the information presented. Users are advised to review the Safe Practices / Tips and to conduct commercially reasonable due diligence in regards to each company that they may do business with.

The PAPI system consists of four-light units, which locate at the side of the runway adjacent to the origin of the glide path.

The nominal glide slop angle is midway between the angular settings of the central pair of the four units.

If the aircraft approach is too high, an increased number of white light indicators will be seen. If the aircraft approach is too low, the pilot will see an increased number of red light indicators.


The PAIPI-640-H unit is in compliance with standards:

Main Advantages

l Using precision angle sensor to detect the tiny change of the inclination angle of each unit (precision 0.6 minute), and the real-time data is showed on the LED digital tube display at the back of each indicator. When the angle deviate more than the setting value (normally not exceeding 15 minutes), the system will shut off itself, and alert the control center.

l The special optical strengthened filters have high transmission factor and good thermal resistance, and with no discoloration.

l Structure design ensures very good water-tightness and protection against corrosion, and ensures the electronic components not affected by the heat from the lamps. The structure has gotten application patent (Pat. No:ZL201320196674.4)
