How do jet engines provide thrust?
SUCK-SQUEEZE-BANG-BLOW More complex answer: Let’s initially ignore the most common type of jet turbine engine in use today, the turbofan, and focus on the turbojet engine, which were used in the US Navy’s A-6 Intruder and F-4 Phantom II. (Typical single spool turbojet engine) The turbofan and turbojet engines share a similar hot section and […]
Why many Aircraft don’t have a row 13
Thirteen is regarded as an unlucky number in many cultures. One (probably unverifiable) hypothesis holds that 13 is a reflection of the human fear of the unknown, since it is the first number that cannot be enumerated using our 10 fingers and 2 feet. Unreasoned fear of the number 13 is termed triskaidekaphobia. Due to […]
Why is the Airbus A380 being discontinued? Is it because of the lack of airline demand?
The rapid demise of the Airbus A380 is a complex tale of missed connections, a changing market and, ultimately, a staggering lack of demand for the largest commercial airplane ever built. And, as a result, this giant of the skies could well be the last of its kind. The decision to stop production on the […]
Do Most Landing Gear Failures Occur at the Nose Landing Gear?
There are those social media arguments that get you hooked at 3 a.m. and keep you scrolling to hear both sides of the story. I was recently hooked by such a thread discussing landing gear failures that gave me more questions than answers. I could not sleep as I kept asking myself “Do most land […]
Why are most runways made of concrete and not asphalt?
The construction material choice for runways is mostly decided either by weather conditions and/or the weight of the aircraft that will use the surface. Asphalt runways are used almost exclusively for general aviation (under 12,500 pounds gross takeoff weight). While almost all runways that are concrete are designed for use by aircraft that weight significantly […]
Can rain cause a jet engine to flame out?
In Jet engines air is compressed by fan blades and directed to the combustion chamber, where it is mixed with fuel and ignited. The hot exhaust gases then exit the engine and provide thrust. A jet engine can handle a large amount of water ingestion, as most of the water is spun out by the […]
How to disable MCAS during flight and manually control the aircraft?
MCAS or Maneuvering Characteristics Augmentation System is a software method of helping prevent unwanted attitudes in the Boeing 737 Max series aircraft. It works by applying nose down Horizontal Stabilizer trim imput when the aircraft’s Angle of Attack exceeds a certain point nearing a stall. Angle of Attack (AoA) is determined through two vanes that […]

ADSB data suggest flight #JU324 to Dusseldorf took off from an intermediate taxiway leaving only reduced length for take-off. The pilots […]
Why does the Boeing 777 fuselage section start from 41 and not 1?
It’s been a unique Boeing tradition since the late 1950s. Boeing’s first passenger jet, the 707, had its nose section designated as section 41 in engineering drawings. There is no planned section in front of the nose section. It is one end of the airplane. It is the portion of an aircraft, extending from the […]
Pilatus PC-12 has lost its left wing during crash-landing at Courchevel, France
This Saturday, February 17 at 10:15 a.m., a Pilatus PC-12 missed its landing at the Courchevel altiport. Its wings left was torn off but fortunately the plane did not catch fire. The pilot and co-pilot, slightly injured, were treated by firefighters and transported to the station’s medical office. French Courchevel altiport (LFLJ) is currently unusable […]
How does an airplane lose cabin pressure? How is it fixed? Does it happen often?
I was in a 757 a couple of years ago conducting a maintenance test flight on an airplane that not flown in about a year. There was a sticky valve that failed to close on takeoff that is used for electronic equipment cooling that is open on the ground. The airplane never pressurized. Climbing into […]
Why is fuel stored in the wings of the aircraft?
The main reason is to balance weight because fuel is one of the heaviest components of an aircraft. On some long-haul flights, the fuel can account for as much as a third of the aircraft’s gross weight. Storing this extra weight in the fuselage would reduce available cargo space and increase the strain and stress […]
What is the difference between a Boeing 737 with winglets and one without winglets?
The primary difference between a Boeing 737 equipped with winglets and one without them lies in their aerodynamic efficiency and performance characteristics. A Boeing 737 equipped with winglets features these distinctive wingtip extensions that serve multiple purposes. Winglets are designed to reduce lift-induced drag significantly, enhancing fuel efficiency by improving aerodynamics. They provide additional lift, […]
Why is the A330 nose landing gear shorter than the main landing gear?
Not only Airbus A330, almost all aircraft have their nose gear shorter than the main landing gear. The main reason is that, when the nose gear will have lesser height than the main landing gear, the pilots will able to get a better view of the runway during ground operations. There could be another reason. […]

Why does the Boeing 747 have the cockpit on the second floor while the Airbus A380 puts it on the first floor?
The placement of the cockpit on the second floor of the Boeing 747 and on the first floor of the Airbus A380 is primarily due to the design choices made by each manufacturer. The Boeing 747, which first flew in 1969, was designed with a distinctive hump to accommodate both the cockpit and a passenger […]

The […]
Why do jet engine fan blades have a curved and twisted shape?
All in an effort to seek more fan efficiency. Fan blades have gone through a number of evolutionary steps. Early jet engines use what are called narrow chord fan blades that are typically made of solid titanium. Because they are thin but long (a high aspect ratio), they required “snubbers” (the ring-like circle going through […]
Which section of an airplane is the most structurally sound?
Interesting question and it might vary by aircraft, but I’m going to make a very educated guess regarding the most structurally sound part of an airplane. It’s the wing and its attachment to the fuselage — although many wings continue through the fuselage to make the wing essentially a single structure. I’ve seen pictures of […]
Where would a flight between New York and London do an emergency landing if it’s engines fail in the middle of the Atlantic?
If all of its engines fail, it will land somewhere in the middle of the Atlantic. There are many possibilities. Now, if it’s a twin-engined aircraft, and ONE of its engines fail, it will proceed to the nearest ETOPS (ICAO: Extended Twin Operations) Alternate Airport associated with the closest ETP (Equal Time Point). If it’s lucky enough […]
“Full white” Avion Express Airbus A320 skids off runway at Vilnius Airport
Vilnius International Airport (VNO),Lithuanian was forced to stop all incoming and outgoing flights on Saturday afternoon after an Avion Express Airbus A320-232 plane (LY-NVL) skidded off the runway 19 during landing. The incident with the Avion Express plane took place at 2:20 p.m. All passengers are safe, airport officials said, but the runway is closed to all flights […]
Does an airplane take off automatically upon gaining sufficient speed or is there anything the pilot must do in order to lift the plane?
We all know that at the right speed, there would be lift on the wings and that the plane would rise up. Only thing is if the plane just continues flat like this, it will eventually lift up in the air, but would rise up parallel to the ground. It will not have the typical attitude of […]
What is a stick shaker on an aircraft?
A stick shaker is a mechanical device that produces a pronounced vibration on the control yoke/stick of an aircraft to warn the pilot of an imminent stall. Most modern transport aeroplanes are equipped with an angle of attack sensor. As an aeroplane will always stall at a given angle of attack (not airspeed) for a […]
