Wilfredo Muldoon: That whatever is going on is OK. For example. the Engines are operating normally, Brake check is good and all systems are go.
Rickey Vrieze: Hi. I operate a small cargo airline and we still have some 737-200Cs in our fleet.We are looking for a replacement but we re not sure what aircraft we have to go with. Boeing isnt producing a cargo version of the 737 MAX yet and the 767 is too expensive for us.The LM-100J (civilian version of the C-130J) looks good since we only carry pallets and no containers.I have some doubts about four engine planes. Since it has four engines it usually burns more fuel than twin engine planes. But because turboprop engines usually have higher by pass ratio and it has new blades, i guess they could burn less fuel than the old 737-200 with old engines?Like the 727 is smaller than the 757 but the 727 burns more fuel than the 757 and UPS replaced their 727s with the newer 757.Do you think it is a good idea to replace 737-200s ! with civilian C-130Js?
Hyo Hardell: It simply means affirmative. That is how it is denoted in the ICAO handbook for marshalling signals. Nothing more, nothing less.
Jed Porada: I think it's that they are doing ok with what there doing =D
Marti Declue: "i guess they could burn less fuel". Why are you guessing? You MUST NOT guess on something like this. Get the facts and do the calculations. Anything less is irresponsible and unprofessional.
Arlen Hamper: Icao Marshalling Signals
Rayford Speziale: Air has a certain moisture content and it is generally very hard to remove this moisture. If an airplane tires were filled with air, at the flight altitude ice would form inside the tires since the temp up there is about -55 degrees C. Landing with a chunk of ice in the tire would make it out of balance and change the tire pressure. Tires would probably burst. On the other hand, nitrogen doesn't form a liquid till -173C and pure nitrogen has almost no m! oisture. In addition, consider if the brakes overheat and caus! e a fire.. The nitrogen will not burn, but air has oxygen which will feed the fire. Jet airline tires are fused. When the fuse is heated it deflates the tire so they don't explode.. .The huge tires on aircraft are expensive, and difficult to mount and dismount. They are also subjected to tremendous forces on landing when they must accelerate very quickly. The friction on touch-down creates great heat within the tires and produces very high stresses in the walls of the carcass. Therefore, every effort is made to reduce or eliminate the deterioration caused over time by oxidation. Since normal atmospheric air is approximately 20% oxygen, the tires are inflated with 100% nitrogen - a relatively inert gas. (Not my work, but copied from link, below)
Russell Mckinzie: Nitrogen is less likely to migrate through a tire than air is ~ preventing pressure loss. It also is less reactive to temperature changes, which helps maintain a steady ! tire pressure.
Roxane Leathers: Thumbs down is for while i think of somebody is being completely ridiculous or downright impolite and insulting. If human beings are not getting a `thumbs down` for promulgating racial hatred, we would desire to assert, different individuals will look on the respond and think of that I and all of us accept as true with or have discovered no insult or undesirable feeling contained interior the respond. that would not look sturdy to something of he international and makes us all look heartless or detached. many of the rubbish spouted out in this section is disgusting to assert the least and to enable it circulate `unthumbed` could be morally incorrect. Now, reporting is a distinctive count number. I one hundred% have faith in freedom of speech, yet I even have had the main possibility free solutions bumped off by capacity of the religista. How approximately, "confident somewhat" as `no longer an answer` ??? EDIT: a minimum of in case you'! re turning out to be thumbs in any direction, you be responsive to indiv! iduals are interpreting what you're saying, whether they don`t like it....Show more
Marcellus Yoshimori: It means "everything is okay".(Airlines) If you watch closely you might also see the Captain signaling for engine start. This signal is the crew holding one or two fingers in the air (or three and four for larger aircraft). The fingers denote which engine they are going to start (#1 is the left side, #2 the right).Once the pushback is complete, the standard hand signal is to make two fists, which signifies setting the parking brake so that the ground crew can disconnect the tug. Once the tug is released, you'll see the ground marshaller point in a particular direction (go that way), and give a salute. This signals to the crew that the aircraft is visually inspected and okay, and they are released to taxi. At this point you'll often see a return salute, a wave, or a thumbs up.(Military) If you see a thumbs up in the military (carrier operations), it's a signal that ! the aircraft is okay and the catapult numbers are okay. Before each carrier launch, the ground crew and launch officer needs to "dial in" the aircraft weight so that the proper launch speed/pressure can be set into the catapult system. To do this, the ground crew will verify the aircraft weight with the aircraft commander (pilot) via a chalkboard. When he/she is ready for launch, the pilot will give a thumbs up and salute, signifying that they have reviewed the number being presented and it checks, the aircraft is ready to go, and all systems are normal....Show more
Mitchell Pickens: I went to several web sites and deduced the following:1. Aircraft tires get much hotter during taxi, takeoff and landing. They run at much higher speeds during takeoff and landings (140 mph and higher) and support much, much heavier weight.2. This heat causes moisture in the air (inside the tire) to expand causing tire pressures to increase.3. Nitrogen doesn't have the high moisture c! ontent.4. Nitrogen doesn't oxidize or react to aluminum wheel parts5. ! Nitrogen doesn't degrade rubber6. Aircraft operate at much higher altitudes were air pressure differentials are greater. Moisture in air can condense out with these pressure changes.With that being said, why do I not use nitrogen in my car tires?1. Too expensive. Some places charge$30 for a nitrogen purge and fill up2. My tire treads wear out after about 50,000 miles long before the rubber degrades due to the use of plain air.3. The $30 price negates any savings on fuel mileage, tire life or other "costly" issues.4. My tires always have about 78% nitrogen inside them anyway. Air is 78% nitrogen.5. Using nitrogen adds to the cost of fixing a flat tire because of the lost nitrogen. Nitrogen will not prevent a flat tire due to a puncture from a nail.One experiment I read about (for the family car) was this. The front tires were filled with air and the rear tires were filled with nitrogen. After 6 months, tire pressures were relatively the same.
Bethanie Men! den: Everything is good
Ayesha Genova: Nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term.
Ronnie Panas: Since you say at arrival I am guessing after the ground crew plugs in external power they normally wait for a signal that it is connected and working properly. The cockpit crew will normally give them a thumbs up when this happens.
Patricia Bolduc: thanks for the answers. I'd like to add that i'm asking about the arrival of an aircraft, not departure.
Hal Palowoda: Jared, I went to ERAU. It is a very good school (among the best), but my own personal experience of having graduated there 25 years ago is that it wasn't the best choice I could have made. As far as I have been able to determine, getting my AS and BS degrees from there has not given me any special advantage in getting flying jobs over someone who got a degree elsewhere. In fact, I current! ly fly with a guy who has no post-high school education at all, but a l! ot of flying experience, including flying B-747's for a frieght company that went under.You also want to consider the fact that the "Aeronautical Science", Professional Aeronautics", or "Aviation Management with Flight Concentration" degrees are very poor for finding decent professional employment outside of flying for a living, and you may find yourself in that position someday. If a flying career stalls (economy), takes a bad turn (perhaps a violation), you lose your medical certificate health problems), or you simply get tired of the aviation rat race, you'll wish you had a degree in almost anything but one of the three mentioned. Due to major ups and downs in the economy over the last quarter century I've found myself furloughed or permenantly laid off about 1/5 of the time. Having a non-aviation degree, say in business management, or computer technology, or engineering would have been quite helpful. I don't dislike ERAU, but if you have your sights set on an airline c! areer, be aware that none of the U.S. airlines (and many foreign carriers) really give a hoot where you earned your college degree, what kind of degree you have, or where you learned to fly, so long as you attended an accredited college or university and have the requisite qualifications and flying experience. You don't really even need a college degree, although it is very much harder to get hired without one since 95% of airline applicants hold at least a 4 year degree. Getting flying jobs is 50% who you know, 40% your work history, and 1% where you went to school or learned to fly. FACT.Also, ERAU is very expensive. I paid for it myself and it took me 13 years to pay off that huge, unnecessary debt. Currently, 4 years of tuition, room and board, and flight training through multi-engine flight instructor will set you back at least $150,000. That's a gigantic financial hole to dig yourself out of if you have to borrow the money to pay for it. Most entry-level flying jobs ! in the U.S. only pay about $20k or so per year. Chances are, unless you! have good connections, it's going to take at least 5 years before you'll start earning anything decent income-wise. Unfortunately, while there are lots of scholarships, very few are available that pay a significant portion of the expenses.I'm not trying to talk you out of going to ERAU, but these are some things well worth considering from someone who has truly "been there, done that". Good luck.Ben
Patricia Dornbos: Embry-Riddle is a very well respected aviation school in the US, if you decided to go there its a good choice. I have known quite a few people that have attended the school Good luck with your career!
Neville Dautremont: It means affirmative...all clear or ok
Lorelei Lilburn: For the best answers, search on this site https://shorturl.im/ax8FpNitrogen why because, Being an inert gas, it cannot catch fire or explode or aid combustion. Tyres inflated with nitrogen run between 10 and 15% cooler. Tyres inflated with air run hotter than those infla! ted with nitrogen. Nitrogen disperses heat quicker than air. Tyres run cooler and tyre life is extended by up to 20%. Tyres inflated with nitrogen do not lose pressure as quickly as those filled with air. Even Formula 1 Cars do use Tyres filled with Nitrogen
Ellis Cellar: I want to attend Embry Riddle for college. I know it is very expensive, but what I want to know is: is it worth it? What is so special about that school as compared to other schools? Are there any scholarship programs, or financial aid? What advantages will it give me in the future?I want to hopefully become an airline pilot
Tricia Dossous: On Arrival the pilot usually gives thumbs up after the ground crew has given the pilot the signal for the chocks being in place and/or the ground electrical power being conected. He then gives the thumbs up to let the ground crew know he has the ground electical power available to him.
Fermin Tara: Percussim has it exactly tight - best answer to him! N! itrogen has the same properties as air in terms of expansion with tempe! rature and molecule size, but bottled nitrogen is dry and does not oxidize the tires or (even more important) the rims.Cars get most of the tire deterioration from outside - sun and debris - and we can keep an eye on them. If we are on the road when a tire loses air we notice it, pull over, and deal with it. An airplane tire gets tested when the plane lands. A corroded rim or ice in the tire is not a good thing then.
Mickey Isle: I work at an airport, and not even a pilot could answer my question.
Pattie Vold: Low moisture content.
Darrin Hixenbaugh: Oh, that is Steve Bowlin? Occasionally aka Blue Face Anonymous.Yesterday he was pretending to be a 787 captain, today, "operates" a small cargo airline.With such a background you can only expect him to be irresponsible and unprofessional.Just a bored kid playing with his PC, and dreaming of airplanes.He could not even figure how much gas it takes to drive 100 miles, with a 25 mpg car...
Elden Dedon: a de! gree from ERAU gets at least as much respect as a degree from most state universities.
Ivan Velazquez: The simple answer is that nitrogen isn't effected by the severe temperature change that airplane tires encounter. The pressure stays consistent.
Armanda Hertel: It means I am ready to F,n go
