Question about Super Tutor Trigonometry (ESDTRIG) for PC

1 Answer

Distance problem? The pilot of a small plane finds that the airport where he intended to land is fogged in. He flies 55 miles west to another airport to find that conditions there are too icy for him to land. He flies 20 miles at 15° east of south and is finally able to land at the third airport. How far and in what direction must he fly the next day to go directly to his original destination?

What happens if a private Cessna 172 pilot tries to land at big airports like JFK or O'Hair when there is no emergency?


It's quite permissible to do so, however a general aviation pilot in a low performance plane should be ready for fast instructions and quite a bit of maneuvering to stay out of the way. The best time to do it would be at night. Here's a youtube video of one doing it. https://www.youtube.com/watch?v=KKvWn317tpU

Will pilots be needed in the future? or planes will fly by themselves?


For the foreseeable future there will be a good demand for pilots. Some planes can already auto land with no pilot input but it will be many years before pilots disappear and there is almost always a pilot shortage.

Is it common that small local airports don't have radars?


It is very common for small airports not to have a control tower, radar, or communications equipment. There are very well developed procedures for "uncontrolled airports". There is a standard traffic pattern that aircraft fly at almost all airports (consisting of a downwind, base, final, and upwind leg) and there are specific radio calls that are supposed to be made at certain points in the pattern. Most airports have a fixed base operator to supply fuel and services. They often monitor the common traffic frequency and supply some info to pilots about wind direction and runway in use. There's also a specific way to enter the pattern - usually at a 45 degree of the downwind leg, Yes it's possible for aircraft to collide and it happens several times a year - usually when a low wing airplane is above a high wing airplane in the pattern. Neither can see the other so occasionally that can happen.

Where do you land if there is an emergency during a trans-atlantic flight?


You're stuck with a water landing (ditching). Hopefully at altitude the pilot can see a ship and make the landing in the vicinity of the ship for quick rescue. It so rare for a plane to lose power to all engines though that you should never hear of such an incident. Depending on the route, however, Bermuda may be within gliding distance.

How is a pilot supposed to find out their distance in miles from an airport they're landing at?


Using the old (pre GPS) method you would use the sectional and plotter (aviation ruler) and measure the distance. Using a GPS you can usually turn on distance rings on the screen or if you have the airport selected as destination you can read it right off the screen. If it's your home base you should learn the landmarks and their distances from the airport. In the Miami area, there are so many airports and landmarks, if you're flying there, during your preflight preps you should measure out distances to some landmarks that you plan to pass over and mark them on the chart or flight log.

Why do some small planes and helicopters just fly around aimlessly?


Students and certificated pilots both are required to remain current and to have a check ride (flight review with an instructor) every 24 calendar months. The ones you're seeing are probably going out to the practice area to practice their flight maneuvers. If a pilot doesn't practice regularly his or her skills can deteriorate rapidly.

A plane is 48 miles west and 49 miles north of an airport. The pilot wants to fly directly to the airport. What bearing should the pilot take? Answer should be given in degrees and minutes.


Draw the airport. (X marks the spot) Draw the distances from the airport (to scale) to indicate the position of the Plane. Use a protractor to work out the correct angle.

To Calculate:

a=48 b=49 Angle= Tan-1(a/b)

On a round trip of 400km,a pilot wants to determine the airspeed of hiis light plane. He flies the entire distance at the same airspeed for the first 200km a steady headwind slows him down by 30km/hour....


v will represent plane's airspeed.


We can divide pilot's trip in 2 parts:
  1. first 200km, when he is flying with speed v. The time it takes him to fly this part of trip is t=200/v
  2. last 200km, when he is flying with speed v-30. The time it takes him to fly this part is 200/(v-30)
The time it takes him for second part of trip is also equal to 1.5-t (because entire trip takes 1.5h), so now we can write equation:

1.5-t=200/(v-30)

We also know that t=200/v so we substitute that into equation:

1.5-200/v=200/(v-30)

To solve this equation we multiply it with v*(v-30)=v^2-30v first. We get:

1.5(v^2-30v)-200(v-30)=200v

Now we get rid of brackets:

1.5v^2-45v-200v+600-200v=0

or

1.5v^2-445v+600=0

This is quadratic equation, so we get 2 solutions (sqrt= square root):

  1. v=(445+sqrt(445^2-4*1.5*600))/(2*1.5)=295.3 km/h
  2. v=(445-sqrt(445^2-4*1.5*600))/(2*1.5)=1.4 km/h
We know that only v=295 km/h is solution because if 1.4 km/h was solution that would mean that second part of trip plane was flying with speed 1.4-30= -28.6 km/h, so that would mean he was flying backwards (which we know he didn't because it's round trip). Speed 1.4 km/h is also not physical solution, because plane wouldn't be able to take off with such small speed :)

An airplane is flying at a height of 2 miles above the ground. The distance along the ground from the airplane to the airport is 5 miles. What is the angle of depression from the airplane to the airport?


a2+b2=c2
a being your height, b is your distance from the airport and c is the distance from the airport to the plane........ so the answer is 5.385164807134504 miles

Trig and distance


Debs,

this is solved by starting with the SECOND leg of the flight considered as a triangle.

Find how far DUE east the plane travels (100 km x Cos10 = 83.9 km) using 10 degrees because that is how much is left of the 90 degree quadrent after subtracting the 80 degrres course direction.
Similarly find out how far DUE north the plane travels (100 km x Cos80 = 11 km).

Now get the total flight NORTH = 300 + 11 = 311
- and total EAST = 83.9

Finally, use Pythagoras theorem.to get the total DISTANCE:
square root of ( 311 squared + 83 squared ) = 321 km

Also the DIRECTION from its Tangent of 83 /311 = 14.9 degrees
