Why can t commercial airplanes use electronic view screens, like on Star Trek?

That would eliminate the Laser problems

Landing using just instruments predates 'glass cockpits' by several decades. I remember as a teenager being on a 707 flight deck during training

There are many proposed airliner designs that intend doing away with windows for the passengers entirely and replacing them with screens. One even suggest just making the whole top half of the cabin into one huge LCD screen so it feels like you are flying in an open-top bus :-) The reason is that windows are a weakness in the fuselage; all the stresses of pressurising the fuselage act at the windows. This is why you still have your ears pop; they cannot maintain full ground level pressure at altitude.

Landing using just instruments predates 'glass cockpits' by several decades. I remember as a teenager being on a 707 flight deck during training when the whole screen was blocked during approach to test the pilot could still maintain the correct angle and speed on instruments alone (though they did not expect him to actually land blind without ILS) And of course even light aircraft pilots can train in Instrument Flying for flying inclouds, night etc. The term 'Glass Cockpit' refers more to the use of LCD displays instead of mechanical gauges. It is worth noting that even in a 'glass cockpit' they still use dials as well as numbers. When a pilot needs to scan dozens of readings in half a second then reading numbers does not work very well. The pilots prefer to see that things like temperatures and pressures and voltage levels etc are in a dial format so they can see that the needles are in the correct place with the briefest of glances. If one needle is out of place amongst 6 small dials it is glaringly obvious but one number being different from the 5 around it is hard to see.

Modern Jet airliners already have electronic screens that depict the ground, the sky, maps, terrain and many more things, They are known as "Glass Cockpit" aircraft. These aircraft can land in Zero visibility fully automatically without the pilots having to see out of the window at all, just viewing the screens. The problems are in training of the flight crews. Full automated approaches and landings are far more exacting on the flight crew than a normal visual landing and crews have to be specially trained and certified to do them. The thought that on an automatic landing the pilots just sit there and do nothing is far from reality. The procedure is one of intense concentration and if the aircraft so much a twitches the pilots will abandon the approach, they have to watch everything. Training flight crews is a very expensive business and an international operator would have to have about nine crews for just one aircraft. Training those crews to operate with just view screens would blow the training budget out the bank. No matter how cleaver these modern jets are the fastest computer on board is still the one between the pilots ears and using all his senses and especially sight through a window will be with us for some time.

Do you need a type rating to fly your own Bitchcraft 1900 or Cessna CJ2?


The type rating is required in aircraft that need additional training. It is a safety of flight issue not a for hire issue.

What are some advantages and disadvantages of airplanes in world war 2?


Great book to read is "Wings On My Sleeve" by Eric Brown. Only pilot in the world to have flown most of the airplanes of WWII.

Pilot Career Help?


Usually, once you have a private pilot certificate you would go for an instructor rating and work as a flight instructor to build flight time (while making money). Along the way you could also be working on your commercial, multi engine, and air transport pilot ratings and certificates. It takes time to get into the airlines, mostly because you need to build flight time and experience. Even when you first break into the airlines the pay is kind of pathetic, but it builds quickly over time.

What are some limitations on airplane flaps?


Usually it is airspeed of the aircraft. Each aircraft has different airspeed requirements for operation the flaps or landing gear. Usually that speed is determined by the airframe manufacturers and the design of the flap system component. You could built it strong enough to handle any airspeed, but a plane can only carry so much weight. If you built everything to work without any limitations you might have an airplane too heavy to fly. Designing a plane is a balance between lifting capability and weight. Both of these are important design parameters.

How high does a plane on short trips vs. on long trips or is the altitude the same?


Your question is a good one - but the answer is much more complicated that you would expect. Think about driving your car from point A to point B across a city. Lots of paths - some shorter than others, but the shortest path may not be the quickest. Or the quickest may involve a toll road - and you may or may not be in a hurry.

The usual most important factor (for commercial operations, at least) is to save money, while still arriving on time. Airplanes in the air are subject to the winds aloft, which will generally be at different strengths AND DIRECTIONS at different altitudes. Most airplanes operate more efficiently at higher altitudes (up to limits), but at those higher altitudes the plane may face stiffer headwind. Further, it costs time and fuel to climb to those altitudes, and you will not regain coming down as much as it took going up. [Think of a bicycle on hilly terrain vs. level ground.]

So what's the answer? Well, for most trips the pilot will consider all these factors. They are taught during training how to plan the flight in terms of time and fuel required, and to include in that especially the winds at different altitudes. Then they will pick the altitude, whatever that is, that maximizes the results that they consider most important.

Airplane question?


That would be the ground prox system on the aircraft it lets the flight crew know how far they are above the ground during an approach to the landing runway.

Why no whole-plane parachute system on commercial flights?


Aircraft too heavy. Weight is extremely valuable/expensive and the weight of a parachute system would be too heavy and costly, sacrificing room for paying passengers.
