    Dear friends and followers, welcome back to my channel and to a great video about visual aids for pilots. We´ll be looking at the PAPI lights, how they work, and especially how to use them whilst you´re on approach.

    The PAPI is a light array positioned beside the runway. It normally consists of four equi-spaced light units color-coded to provide a visual indication of an aircraft's position relative to the designated glideslope for the runway. An abbreviated system consisting of two light units can be used for some categories of aircraft operations. The international standard for PAPI is published by the International Civil Aviation Organisation (ICAO) in Aerodromes, Annex 14 to the Convention on International Civil Aviation, Volume 1, Chapter 5. National regulations generally adopt the standards and recommended practices published by ICAO. An earlier glideslope indicator system, the visual approach slope indicator (VASI) is now obsolete and was deleted from Annex 14 in 1995. The VASI only provided guidance down to heights of 60 metres (200 ft) whereas PAPI provides guidance down to flare initiation (typically 15 metres, or 50 ft).

    The PAPI is usually located on the left-hand side of the runway at right angles to the runway center line. The units are spaced 9 meters apart with the nearest unit 15 meters from the runway edge. A PAPI can, if required, be located on the right-hand side of the runway. At some locations PAPIs are installed on both sides of the runway but this level of provision is beyond the requirements of ICAO. The light characteristics of all light units are identical. In good visibility conditions the guidance information can be used at ranges up to 5 miles (8.0 km) by day and night. At night the light bars can be seen at ranges of at least 20 miles (32 km).

    Each light unit consists of one or more light sources, red filters and lenses. Each light unit emits a high-intensity beam. The lower segment of the beam is red, and the upper part is white. The transition between the two colours must take place over an angle not greater than three minutes of arc. This characteristic makes the color change very conspicuous, a key feature of the PAPI signal. To form the PAPI guidance signal, the color transition boundaries of the four units are fixed at different angles. The lowest angle is used for the unit furthest from the runway, the highest for the unit nearest to the runway. The designated glideslope is midway between the second and third light unit settings. Depending on the position of the aircraft relative to the specified angle of approach, the lights will appear either red or white to the pilot. The pilot will have reached the normal glidepath (usually 3 degrees) when there is an equal number of red and white lights. If an aircraft is beneath the glidepath, red lights will outnumber white; if an aircraft is above the glidepath, more white lights are visible.

    PAPI systems are readily available from airfield lighting manufacturers worldwide. PAPI is normally operated by air traffic control (ATC). If ATC services are not normally provided at an aerodrome, PAPI along with other airport lights may be activated by the pilot by keying the aircraft microphone with the aircraft's communication radio tuned to the CTAF or dedicated pilot controlled lighting (PCL) frequency.

    Thank you very much for your time! I hope you enjoy this basic introduction video about the PAPI!
    Wishing you all the best!

    Your "Captain" Joe

Hey Captain Joe, I'm not.a fan of the somber music tone in some videos. It sounds like foreshadowing for disaster while you are brightly explaining things in an upbeat tone. I get it if the music is relating to somber situations such as a possible crash, but it's a little spooky for some videos about regular equipment, procedures, and practice. Not a big complaint it's just that you personally are much more upbeat than the music & it kind of makes me think of planes crashing. Still watching, just a theatrical observation. Best wishes.

Since an aeroplane which needs to land is constantly in motion about a specific high speed and needs to gain specific profile (height, distance, speed, angle at a specific point before landing), My brain fails to understand how can a piolet manage to get the aeroplane which is already moving say 900 km/ hour achieve to reach a specific profile at a specific point at a predetermined distance from the runway? By the time the piolet pushes certain buttons and changes the lever positions how do they achieve that kind of an accuracy while an aeroplane which drifts away from a specific point at 250 meters per second ???
