A holding pattern is nothing more than a big oval formed in a race-track shape that is designed to keep an aircraft in a specified space for a specified amount of time.

Here is an audio/video file with transcript about how the numbers must be pronounced according to the ICAO (International Civilian Aviation Organization) standard. This is how aircrew members, and air traffic controllers should transmit the numbers.
CAUTION – There is not any exception for FL 100, and FL 200 according to the ICAO DOC 9432 Radiotelephony Manual, page 19, chapter 2.4.2, as it is pronounced « FLIGHT LEVEL ONE-ZERO-ZERO », and « FLIGHT LEVEL TWO-ZERO-ZERO ».
However, « Flight level one hundred » follows the French DGAC and the British CAA patterns.

Watch and listen carefully to Mr. Learmount’s point of view which has been deemed to be of considerable interest as far as the 2009 AF 447 crash is concerned. Please notice that there are interesting acronyms such as GIGO (Garbage in – Garbage out), and LOC – if it is well known as « Loss of Consciousness » – means « Loss of Control » here. Special thanks to Xavier Cotton (Passion pour l’aviation webmaster) who has found out this video:
Special thanks to Thierry Hermas who teaches English radiotelephony at the French Air Force Academy (EOAA Salon de Provence). Indeed, he has analyzed, and compiled some extracts of the Air France Flight 447 reports issued by the BEA (Bureau d’Enquêtes et d’analyses pour la sécurité de l’aviation civile – Flight safety investigations and analyses bureau www.bea.aero) for training purposes.
