International Civil Aviation Organization

Therefore, aircraft at higher altitudes are able to transmit and receive at greater distances.

In March of nineteen ninety-seven, the International Civil Aviation Organization, ICAO, amended its international standards and recommended practices to incorporate a channel plan specifying eight point three three kilohertz channel spacings in the aeronautical mobile service.

The eight point three three kilohertz channel plan was adopted to alleviate the shortage of VHF ATC channels experienced in Western Europe and in the United Kingdom.

Seven Western European countries and the United Kingdom implemented the eight point three three kilohertz channel plan on January first, nineteen ninety-nine.

A review of the pilot slant controller glossary contained in the Airmen's Information Manual assists a pilot in the use and understanding of standard terminology.

The Airmen's Information Manual also contains many examples of radio communications.

ICAO has adopted a phonetic alphabet, which should be used in radio communications.

When communicating with ATC, pilots should use this alphabet to identify their aircraft.

Brazil are looking to implement a somewhat of a mandate, which is more of a life cycle and missions approach.

You have schemes as well on a more global scale, such as Corsair, which is an ICAO platform or scheme.

So it's a carbon offsetting reduction scheme for international aviation.

And that sets a baseline emissions factor for all airlines that have opted in.

And this incident brought attention to the issue of volcanic ash and aeronautic safety.

Afterward, the International Civil Aviation Organization established a global network of volcanic ash advisory centers, and to this day, they monitor volcanic activity and share data about ash clouds, their size, location, and movement, so that air traffic patterns can be adjusted to avoid them.

But I just want to conclude here by sharing Captain Moody's final takeaway on all this.

In an interview later, when asked what it was really like to be in that cockpit as the plane lost power, he said, quote, It was a little bit frightening.

Extremely cold temperatures will also affect altimeter indications.

Figure seven dash four, which was derived from ICAO formulas, indicates how much error can exist when the temperature is extremely cold.

Setting the altimeter.

Most altimeters are equipped with a barometric pressure setting window, or Kollsman window, providing a means to adjust the altimeter.

A standard pressure lapse rate is one in which pressure decreases at a rate of approximately one inch mercury per one thousand feet of altitude gain to ten thousand feet.

Refer to Figure ten dash two.

The International Civil Aviation Organization, ICAO, has established this as a worldwide standard, and it is often referred to as International Standard Atmosphere, ISA, or ICAO Standard Atmosphere.

Any temperature or pressure that differs from the standard lapse rates is considered non-standard temperature and pressure.

There is an interesting element, if I just jump ahead.

In the consultation on page 12, there's a very clear statement that says ICAO material identifies that in the high seas airspace, the only form of airspace infrastructure that can notify hazard activity is a danger area.

Now, that's quite a powerful statement.

the consultation, which from my view, I haven't seen answered by the proposal.

You mentioned about that.

I mean, just to mention, I was reading from my notes, I think on page 9 to 11.

Yeah, it talks about, did not support, the ICAO panel did not support guidance for airspace reservations.

And is it just, you know, what would a reservation entail? And is this the CA's own approach, trying to say we will impose a danger area for this? And if not, what else could be done instead?
