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. A holding pattern can be published on either airway charts or terminal charts or can be unpublished, and specified by the air traffic controller. Watch the video (from 1’49 »):
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.
A pilot risking his life onboard a 53d Weather Reconnaissance Squadron WC-130J Weatherbird weather reconnaissance aircraft, observed the hurricane in the eye of the storm and reported winds at around 100mph today:
New-York braces for what could be the most destructive hurricane since 1938 maybe 1821. South and North Carolina are beginning to feel the effects of Irene. As showed in the videos hereafter, Irene might cause widespread damage particularly by flooding well beyond the coastal cities such as Virginia Beach; Norfolk; Atlantic City, as well as Kill Devil Hills, the site of the Wright Brothers National Memorial close to Kitty Hawk:
First of all, here is a video on the first T-50’s public display (Moscow – MAKS 2011, August 17, 2011):
The Lockheed Martin/BIDS F-22 Raptor, and the brand new Sukhoi T-50 PAK FA are the current leading-edge 5th generation fighter aircraft. Lots of people would like to assess the capabilities of the two fighterjets. However, no aircraft can be compared regarding its specifications only as fighter aircraft are designed within a wider system – radars; weapon systems; training; and sharing information through data links.
All we know is that the F-22, and the PAK FA are equipped with excellent AESA radars. Though still secret, the Raptor’s stealth is deemed to feature a record-breaking RCS (Radar Cross Section). The T-50, which is to be fielded within the Indian and Rusian air forces, might be equipped with anti-AWACS missiles. The Chinese Chengdu J-20 has not disclosed much information so far, but it will be interesting to this new 5th-gen fighter with the two other aircraft.

The DARPA and USAF FALCON project might give anybody the thrill of speed as this « aerospacecraft » has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!
Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X) had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):
DARPA stands for Defense Advanced Research Projects Agency
FALCON stands for Force Application and Launch from CONtinental United States
FL stands for Flight Level (FL x 100ft = altitude)
HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
RCS means here in the videos: Reaction Control System (and not Radar Cross Section)
