  • What's the minimum flying speed of a boeing 737-800?

    Best answer: Stall speed?

    It depends on weight, and landing gear and flaps/slats positioning.

    Shall I give an estimate?

    Stalling "clean" (landing gear up, no flaps/slats) is 128 knots (147 mph).

    Stalling "dirty" (gear down, flaps/slats extended) is 108 knots (124 mph).

    Final approach touchdown speed is 140 knots (161 mph).

    Your question doesn't have an exact answer.
    I wouldn't fly anywhere near 108 kts dirty.

    You are questioning the aircraft's lift or airfoil.  Things like temperature, atmospheric pressure, humidity, density altitude all affect the lift and therefore the stall speed.

  • Would you be O.K. being drenched by aviation fuel that was "jettisoned" by a low flying aircraft that was making an emergency landing?

    Best answer: No, but I'd understand that it was an emergency and nothing else could have been done because the plane needed to land if it had too much fuel onboard it would crash.

  • Is the SR - 72 ( Blackbird 2 jet ) when finished and in service would the aircraft be considered a Generation 5 fighter jet ?

    Best answer: The planned SR-72 is a UAV, not a manned fighter. It will have zero air-to-air capability.


    Neither the U-2 nor the SR-71 are generation anything fighters, because *neither one is a fighter aircraft*.

  • Can pilots use a noise enhancing technique for arrivals?

    We live 25 miles from our local airport. The noise is unbearable, children in our neighborhood wake up crying it is so loud. I read that pilots can use a method that would reduce noise, however, it sounds like the pilots sometimes put the jets in another "gear" making it even louder than it has to be because a jet at 3,000 feet can sound much louder than another jet at the same exact altitude.

  • Could Boeing provide airlines with the 737 NG since the MAX is grounded?

    Best answer: Being can't really do this.
    The whole supply chain is geared with a lot of just-in-time components some of which have a lead time several months.
    The 737 NG uses CFM56 engines, while the MAX use LEAP engines. Asking CFM to to ease up on the production of LEAP and to make CFM56 instead would not see engines delivered for months.
    But assume that airlines would accept the substitution; then what would happen once the higher performance MAX is again allowed to fly. Are they going to be traded for MAX, and if so, what will be the fate of the NG that would have been offered as an interim?

    Given that the MAX production rate was supposed to be 500 per year, that 387 had been delivered when the type was grounded, and that 400 have been made since (and presently stored) and that there was 5000 orders (i.e. 10 years production) most clients would not have received their last year (or this year) anyway.

    Boeing got 93 cancellations for MAX in 2019; while the NG got 63 new orders (with 44 left to deliver as of last November); you can venture that some airlines may have decided to do a switch, but perhaps this option is not as popular as it could be.
    Airlines ordered the MAX because it was supposed to save them on operating costs.Meanwhile, Airbus had 674 orders for A320's, 112 MORE than the orders they got in 2018. You can draw your conclusions...

  • How come zeppelins/blimps didn't make a comeback?

    Zeppelins would be the best way to travel fast for people with money. They can be very luxurious inside. They are like the cruise ships of the sky, but travel across the pond much faster than a ship does, and without the cramped space and lousy facilities a traditional airplane has, even in most first class cabins. Why don't airlines have such aircraft available for wealthy passengers to buy tickets for? Sure, the Hindenburg disaster was a tragic one that shocked the world, but only 25 years prior, the Titanic disaster was even greater in terms of lives lost, and no one was speaking of ending cruise ship travel. And today, we have better safety features and technology for both.

  • Did the supersonic Concorde retire in respect of 9/11 victims ? will there again be supersonic planes for the super rich ?

    Best answer: All the answers are wrong!  Neither the crash nor the high fuel cost had anything to do with its retirement.  After the crash Airbus designed, certified, and retrofitted a number of safety improvements to the Concorde, including Kevlar lining of the fuel tanks to prevent tire debris from puncturing the tanks and burst resistant tires.  Why go through the effort and expense of that if you intend to retire the plane?  There was still plenty of fatigue life left on the airframes, and British Airways, for one, would have been quiet happy to continue to using them until the end.   

    It was also not more expensive to operate than other planes.  The Concorde operating cost per flight hour (including fuel, crew costs, maintenance, wear and tear, etc.) was comparable to that of a Boeing 747.  While for London to New York trip its cost per seat per mile was higher than that of a 747, the higher all first class fares more than made up the difference.   Immediately after 9/11 the airline industry experienced its worst decline ever.  Passenger numbers, including the premium passengers who comprised the Concorde's target market, dropped precipitously.  In response airlines grounded their older planes, stopped ordering new ones, and cancelled or postponed already existing orders.  This, of course, had an effect on the bottom line of the aircraft manufacturers, Airbus and Boeing. Airbus inherited the Concorde program from the  Aerospatiale, the company that built the Concorde.  Airbus never really made any money supplying the parts for a fleet of only 14 Concordes but the revenue from supporting the A300/310, A319/320/321 and A330/340 programs subsidized the Concorde support.  In 2003 faced with order cancellations and decline in its spare parts business Airbus announced a number of cost cutting measures, one of which was to end supplying spare parts for Concorde.  So, with no parts both British Airways and Air France were forced to retire them.  

    Will there be other civilian supersonic planes?  Could be.  One of the drawbacks of the Concorde was that it was banned from overflying land at supersonic speed because the loud boom it produced was objectionable to the people of the ground.  Lockheed Martin's Skunk Works, under the contract with NASA, is currently building an X-59 Quiet Supersonic Technology aircraft to demonstrate the "quiet" supersonic boom. The engineers hope that by carefully designing the shape of the aircraft they can reduce the loud boom to a quieter thump, no louder than the background noise.  

    Earlier test flights using NASA's modified F/A-18 yielded promising results.  If the X-59 is successful it may open the door for future supersonic passenger planes and private jets.

  • Why does the Boeing supersonic plane concept look more like the Russian Concorde than the original european concorde ?

    Best answer: I know that Boeing had a proposal called (I think) the 2702,but aside from the usual high speed design necessities like a pointed nose and delta wing, the big difference was their proposal had a swing wing to allow for better handling at low speeds.

  • How are small aircraft delivered around the world?

    Best answer: There are companies that specialize in ferrying aircraft around the world.  Usually this involves installation of auxiliary fuel tanks to extend the range.  Just because the ocean looks vast, doesn't mean that there are no airfields on the islands along the way. 

    There was even a reality TV show a few years back about people delivering small planes all over the world.  Several episodes were about a delivery of Cirrus single engine plane from Singapore to the US going the long way around, via Thailand, India, Dubai, Egypt, Europe and then across the Atlantic via Scotland, Iceland, and Labrador. When they flew across the Atlantic the pilots had to wear survival suits in case they had to ditch.

    Another several episodes were about delivering an old Piper Cheyenne from Florida to the Philippines.  Before they set off the crew discovered a fuel leak that, if went un-repaired, would have caused an engine fire in flight.  Then, half way through the leg from Adak, Alaska to Japan their cabin heat stopped working.
