The nose-down tendency will increase the airplane’s stall speed and make cruise flight much slower. If the CG is located too far aft, the airplane will have a nose-up tendency. This typically is the most dangerous situation. The aircraft will have a noticeably higher cruise speed, but the...
The Tercom system is responsible for a cruise missile's ability to "hug the ground" during flight. The GPS system uses the military's network of GPS satellites and an onboard GPS receiver to detect its position with very high accuracy. Once it is close to the target, the missile switches...
We conclude that for a market to exist for a reduced speed concept, a combination of relatively high fuel burn reductions and/or low speed reductions would be required relative to a similar technology that does not reduce cruise speed.Antony D. Evans...
When you shout into a well, the sound of your shout travels down the well and is reflected off the surface of the water at the bottom of the well. If you measure the time it takes for the echo to return and if you know the speed of sound, you can calculate the depth of the well...
In an airplane knowing your actual speed is very handy, as the aircraft's speed indicator runs off air passing over the plane as you go through the air. This means the GPS can accurately tell you the wind speed and direction when compared to the planes on-board air sensors....
Many anxious flyers are bothered by their perceived lack of control since they have no influence over the safety or performance of the aircraft. Try to regain a little control by reminding yourself that you made the decision to fly and that you can decide how you respond to the experience. ...
This allows you tolog GPS coordinates in your radio, it allows you to keep track of the last known position of your aircraft. This can be helpful for searching for the lost quadcopter if you can’t see the coordinates in your DVR. ...
It was originally designed as an anti-aircraft system, but the newest iterations of the Patriot can detect, target and track ballistic and cruise missiles, munitions as well as aircraft. It was first developed in the early '60s to replace both the Nike Hercules and Hawk air defense missile ...
How to Get Upgraded to First Class for Free on a Domestic Flight Getty Images Most airlines market their premium cabin on domestic flights as "first class," and these are typically spacious armchair-like seats on narrow-body aircraft (those with one aisle). ...
It relies on the high-speed forward motion of the aircraft to compress air, making it suitable for supersonic and hypersonic flight. Ramjets are efficient at high speeds but require other propulsion systems for takeoff and acceleration, due to their inability to produce thrust at low speeds. As...
