Question

Any one knows how to find the distance between the airplane and the runway or how to determine that ?

Answer 1

before the plane land or if the plane is about to land how do they determine or calculate that distance ??

Answer 2

They use the glideslope and outer marker, inner marker and localizer of the Instrument landing system (ILS), the distance is a variable and is a value that changes. The markers let them know when they fly above them.

Answer 3

In addition they have visual nav aids that provide the proper guide angle.

Answer 4

However, if you have a specific situation, like a problem please provide the information. At small airports and small planes, the pilot determines visually and uses his training or experience.

Answer 5

Ever notice those black skid marks on the runway, that is where the pilot wants to set his wheels lol.

Answer 6

A circuit board has 100 uniformly arranged power lines. If one of these lines is shorted, how many of the lines need to be disconnected in order to localize the fault? Assume that a single bus links the lines together, and this bus can be interrupted in places that disconnect all of the lines to the right of the point of interruption. (This will be explained in class.) What might this have to do with the distance an aircraft must be from a runway before it begins an instrument approach?

Answer 7

I m trying to answer this question based on the answer of how they determine that and relate them together

Answer 8

Gee allamiro, this sounds more like an electronic question than a airplane question. Lem the think about this for a minute.

Answer 9

Not really its just a comparison its not really elctrical or electronic its more mathematical and reasoning I guess again I m still wondering

Answer 10

Thanks for help thoguh

Answer 11

Ok sure two better than 1

Answer 12

O.K..The troubleshooting starts at the 50 th line by disconnecting it. The problem states all the remainging lines to the right will be also lifted. If the short goes away, the short has now been isolated to the right group of 50 lines, if the short doesn't go away it means it is now located in the group of 50 on the left. Next you go to line in the middle of the 50 which contains the short and disconnect, again all the lines to the right will be lifted also this isolates to a group of 25, you continue by lifting the middle line of the group that you have isolated the short. It shouldn't take you more than 8 disconnects to isolate it to a single line. You get the idea?

Answer 13

These are two questions sorry I didnt get the idea I thought for the first part you have to run 98 trials to find it since its between two
the scond part is adding a buse that connects all but interrupted at places

Answer 14

Note the problem states the lines are equipped with a disconnect that disconnects it and all lines to the right of it.

Now how this relates to how far an aircraft is out from the runway, well hopefully that will be explained in class lol. I am a retired FAA electronic tech, and have maintained radars and communication equipment used to control aircraft, I must admit I have never had to work on something like that. Now days GPS is the pilots friend, as well as VHF Omni Range (VOR) and Distance Measuring Equipment (DME).
