How do pilots know the flight path?

The DME's signal is used to determine distance. Pilots can then use this information, usually shown by the transponder in the form of tenths of a nautical mile, to plot the path of the airplane. Sometimes DME equipment is paired with VOR stations. Most pilots are now familiar with GPS or a global positioning system.

They are monitored by air traffic control stations they pass along the way. Pilots rely heavily on computerised controls and with the assistance of the autopilot and the flight management computer, steer the plane along their planned route.

Most airlines use a Preferential Bidding System to determine routes. Basically, pilots submit which routes they want to fly (based on location, schedule, etc.) and then a system assigns them routes, with more senior pilots having preference on getting their choices.

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.

Aircraft Instruments that Help the Pilots See in Cloud The pilots also have a weather radar which can be viewed on their screens and this can help them determine what type of cloud it is they are flying through (or approaching), how much water there is in the cloud, and if there are more clouds behind it.

Surprisingly, pilots rarely use autoland, only when the weather dictates that they must. Most pilots prefer to fly the landing manually and only use an autoland when the prevailing weather means they cannot see the runway.

The airlines use the last hours of the day and the first hours of the night to catch up on delays and ensure their aircraft are in the right place for the next day. Night Flights allow the budget airlines and the non-scheduled airlines (usually operating holiday charter flights) to make full use of their aircraft.

The most used is the Instrument Landing System or ILS. The ILS consists of two radio beams which project up from the area around the runway up into the approach path. These signals are then picked up in the aircraft by the ILS receiver which displays them on the screens in the flight deck.

The anemometer, the instrument for measuring speed in aeroplanes. Pilots have to promptly know the speed at which they are moving in the mass of air that surrounds the aeroplane and the anemometer is responsible for measuring it. The anemometer, as it is known today, was designed in 1926 by John Patterson.

Pilots don't earn a flat annual salary like some professions. Instead, they're paid an hourly wage for each flight hour flown, along with per diem. Most airlines guarantee a minimum number of hours per month, so that pilots can count on at least a minimum amount of monthly income.

Managing fatigue is a challenge, particularly when flying overnight (red-eye) flights. Some countries allow pilots to take controlled naps to improve alertness during the landing. So far, the U.S. has not allowed this fatigue mitigation. Pilots keep flight deck lights up, and engage in conversation to help keep alert.

MORE DETAILS

The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.

MORE DETAILS

Instrument approach procedures specify minimum flight visibility to land and minimum decent altitudes. If the clouds are too low or the visibility is very poor, a pilot still can't land. Flight visibility is just one factor, however. Rain can make it difficult to see out the windscreen.

It is not normally the case that pilots wear night-vision goggles. Civilian transport is well equipped enough to not warrant the use of NVGs. Most pilots will use onboard instruments and navigation aids to make their way around the sky at night.

“The first step in avoiding an encounter with clouds at night is a good weather briefing. This weather briefing will give you an idea of where the cloud layers are expected. However, don't expect these forecasts to be precise because they are simply that: forecasts.

Use of visual entertainment such as movies, television programs, video games, etc., is not allowed for a flight crew as they are required to maintain visual scanning outside the aircraft, if able, for situational awareness and collision avoidance.

MORE DETAILS

The simple answer is yes, pilots do, and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.

MORE DETAILS

An airline transport pilot can fly for up to 8 hours within a 24-hour period, and up to 10 hours if there is a second pilot aboard. After flying, pilots are required to rest for at least 16 hours. Some companies have variances to these regulations depending on their operations specifications.

MORE DETAILS

The Federal Aviation Administration (FAA) requires two pilots at all times for most aircraft that exceed 12,500 pounds. Other factors, such as flight length may also demand more than one pilot. One of the biggest reasons two pilots are required for commercial flights and private jets is safety.

These days, many pilots just plug the destination into a GPS, which draws a line on a map, and they follow that line to their destination. If your plane doesn't have GPS, then a tablet or even your phone can run an app that does about the same thing, at least for visual flight rules.
