The famous radio channel Voice Of America has just released an interesting interview. This is about voice communications and aviation English. This conversation is rather easy to listen to. The experienced pilot – Clyde Romero – gives his advice. He helps us understand the challenge between pilots and air traffic controllers when it comes to voice communications. However, would it be possible to implement a large-scale standard aviation english teaching program? La célèbre chaîne radio Voice Of America vient de publier un entretien intéressant sur les communications vocales et l’anglais de l’aviation. Cette conversation est plutôt facile à écouter. Le pilote expérimenté, Clyde Romero, donne son avis. Il nous aide à comprendre le challenge entre pilotes et contrôleurs de la circulation aérienne lorsqu’il s’agit des communications vocales. Cependant, serait-il possible de mettre en place un program d’enseignement d’anglais aéronautique standard à grande échelle?
Special thanks to VOA as the whole transcript of this soundtrack is available on their website: Merci à VOA étant donné que tout le script de cette bande son est disponible sur leur site internet: The Language of Air Travel on VOA.
As you may have heard, the mythical Lockheed SR-71 Blackbird was a strategic reconnaissance aircraft able to fly at more than Mach 3 – Mach 3.3 ie around 3,500 km/h; or 1,900 kts; and at a maximum flight level of… FL 850 or 26 kilometers high!
The Blackbird indeed had a unique flight envelope with a particular doghouse plot (since she could not exceed 3.5 G), and an exceptionnal coffin corner limited by her CIT – Compressor Inlet Temperature of 427°C maximum.
This aircraft was also unique for her engines were two J58 ramjets fuelled by JP-7 especially refined for extreme flying purpose. This special fuel could drip and leak abundantly as the airframe made up of titanium was retracted while taxiing, and became airtight only when it got its operating shape while flying very fast and very high because of the air density, and surrounding pressure plus the heating caused by the air friction at such speeds. In short, the whole structure considerably expanded when airborne.
The irony – I heard it on the grapevine, or read it somewhere on the web – that titanium which turned into dark blue while flying (SR-71s probably deserved those unofficial other nicknames « Bluebird », or « Habu » viper) was « imported » from… USSR!
Pilots must have taken significant risks inherent in flying such an aircraft as mentioned in this previous post. These pilots used to fly over the USSR to take strategic reconnaissance photographs during the Cold war. They wore pressurized spacesuits so that their blood could not boil in case of decompression or ejection at such altitudes.
The Blackbird travelled faster than a rifle bullet, and the air friction could have melt aluminum-skinned aircraft. At Mach 3.2, fuel cycled behind the chine surface in order to cool the aircraft! The inner windshield temperature could reach 120°C even though a heavy-duty cooling system was on a full function. On landing, the outside temperature of the canopy could reach 300°C, and it must have been far beyond on the fuselage, and wing surfaces while flying at high speeds. The pilot could feel the heat behind his protective gloves!
According to the CBS news video report below, F-22 pilots would have stopped flying 5th-generation F-22 Raptor for they would have reported HH (Health Hazards) incidents onboard the most advanced fighter aircraft in the U.S. Air Force, and the most expensive ever.
« The F-22 has been plagued by a mysterious flaw that causes its pilots to become disoriented while at the controls, from a lack of oxygen. »
Thanks to this interview, we now know that a pilot would have touched a tree while flying an F-22 as he may have been suffering from hypoxia (oxygen deficiency in body tissue). Some other pilots reported dizziness, vertigo, and coughing spell.
« The Air Force launched an investigation that focused on the plane’s On-Board Oxygen Generating System, or OBOGS which takes air from outside the jet, passes through the engine, and through a chemical process to produce a concentrated oxygen that the pilot breathes – Watch the video:
Panic onboard – That is what happened on a JetBlue aircraft last week. The captain dashed to the bathroom’s door which was locked, got jittery, then running along the aisle, he hollered out insane things such as « They’re going to take us down! ». The passengers wrestled the pilot down, tied him up with seat belts, and he was handed over to the police after landing.
An incident of this kind had already been reported two weeks before. An American Airlines flight attendant had been giving the safety instructions just before takeoff. She suddenly ranted about mechanical issues which were immediately refuted by the other cabin crew members. She kept speaking incoherently about Al-Qaeda, and the 9/11 attacks, about her fears of crashing, etc. A few people managed to wrestle her down, and the passengers were startled and scared as they could hear her blood-curdling screams when she was being handcuffed by the police.
According to these reports, these insane behaviors are believed to be air-rage cases but the flight attendant who got temporarily mad would be deemed bipolar by doctors, and her condition could explain her behavior. As far as the JetBlue pilot is concerned, his neighbors cannot understand as they would see him as a kind person.
Another scary situations occurred in flight this week on Monday April 2, 2012. 80-year-old Helen Collins landed the Cessna 414 twin-engine aircraft in which the pilot – her husband – died a few minutes before at the controls!
Thanks to the video/audio tape hereafter, we can imagine now what was going through her mind as it was the first time she had flown an aeroplane: (video with transcripts – click on the link below)
Outstanding Helen Collins hurt her back, and cracked a rib but she managed to bring the plane to a safe stop at Door County Cherryland Airport, near Sturgeon Bay, Wisconsin.
Last but not least, HATS OFF to Braden Blennerhassett, an Australian pilot who never panicked last Tuesday as a SNAKE popped out from the dashboard; slithered down his leg while he was landing! Read the SCRIPT and listen to the video link about this story below:
Here is how this brave pilot kept his cool on his aircraft (interview):
Another interesting video with the air traffic controller about the emergency message she received:
These recent stories – not to mention the latest crash of an F/A-18D Hornet from Naval Air Station Oceana, Virginia, on Friday in which the pilots managed to bail out safely before the fighter aircraft crashed into an apartment building fortunately left with no death toll – remind us of this well-worn saying: Flying is simply hours of boredom punctuated by moments of stark terror.
