If flying and you get airsick, you can open vents, use supplemental oxygen, focus on the horizon, take off excess clothing, concentrate on flying and what else?
If flying and you get airsick, you can open vents, use supplemental oxygen, focus on the horizon, take off excess clothing, concentrate on flying and even vomit to help relieve motion sickness. An upset stomach sensation can occur during times of motion sickness because the brain is preparing the body to get rid of your food so vomiting can satisfy the request from the brain and relieve some of these feelings.Scanning eye movements could make motion sickness worse. Eating protein or anything with an upset is not advised.

What is the general shape of a Class C airspace?
The shape and ceilings of each Class C airspace are different for each airport as they are specifically tailored to the airport they surround. However, a Class C airspace usually consists of a 5 nm radius core that extends from the surface up to 4000 ft AGL as well as a 10 nm radius shelf area that extends from no lower than 1200 ft up to 4000 ft AGL.

When telephoning Flight Service for a preflight weather information, pilots should state
When requesting a preflight weather briefing, identify yourself as a pilot or the tail number of the aircraft to be flown and provide the type of flight planned (e.g., VFR or IFR).

A stable air mass is most likely to have which characteristic?
Stable air means smooth air. Unstable air means turbulent air. If stable air has precipitation it will likely be steady and widespread and not showery.
5 / 10
What cloud types would indicate convective turbulence?
Towering cumulus clouds are cumulus clouds that have grown vertically until they are approaching thunderstorm status. Their presence indicated strong updrafts (Convection) and turbulence. Answer A is incorrect because cirrus clouds are high clouds composed of ice crystals and contain no significant turbulence. Answer B is incorrect because nimbostratus clouds only form in stable air and also have no significant turbulence.

What is NOT a mnemonic device used to remember the required equipment for VFR day flight?
Common mnemonic devices to remember day VFR required equipment are A.C.A.F.O.O.T.S.E.A. or T.O.M.A.T.O.F.L.A.M.E.S.A.V.1.A.T.E.S. is used to remember required inspections.

(Refer to Figure 12) What are the wind conditions at Wink, Texas (KINK)?
[Figure 12] Wind direction in a METAR is always the first 3 characters relative to true north, and the speed is the last 2 characters. If the wind is gusting, then the letter G (gusting) is used followed by wind gust speed. Answer A is incorrect because the wind speed at KINK is 12 knots gusting to 18. If the wind is less than one knot, then it is encoded as 00000KT. Answer C is incorrect because the wind direction was decoded using part of the speed, and the wind speed was decoded using part of the direction.

(Refer to Figure 47) What do the VASI lights shown in situation A indicate about your aircraft?
[Figure 47] Situation A shows a row of red lights above a row of white lights on a two-bar VASI which means you are on glide slope.

What often leads to spatial disorientation or collision with ground/obstacles when flying under Visual Flight Rules (VFR)?
Continuing VFR into instrument conditions often leads to spatial disorientation or collision with obstacles.

(Refer to Figure 61) If 50 lbs of weight is located at point X and 100 lbs at point Z, how much weight must be located at point Y to balance the plank?
[Figure 61] These exercises require us to perform some simple math and remember a simple equation. The equation is the equation to calculate a moment. A moment is calculated by the weight of an object multiplied by its moment arm (distance from fulcrum/balance point). This one is a little different because there are two separate blocks on the right hand side. To account for this we simply just have to add up the moment of each block on the right hand side for a total right side moment. That total right side moment must equal the total left side moment. Furthermore, since no weight was given for the plank we should assume it weighs nothing. First lets calculate the moment on the right hand side. The Z block is 100 lbs and is 100 away so the moment is 100*100 = 10,000 lbs-in. We know that to balance the beam on the fulcrum the left side moment from blocks X and Y must equal the right side or 10,000 lbs-in. We are given the weight of the X block as 50 lbs but aren’t told what the Y block weight is. The Y block weight is what we need to find. To do this we can write the moment equation which will be the sum of both left side moments equal to the moment on the right side or 10,000 lbs-in. X*50 + Y*25 = 10,000. We know X is 50 so this turns to 50*50 + Y*25 = 10,000 or 2,500 + Y*25 = 10,000. Now we just solve for Y by first subtracting 2,500 to both sides to get Y*25 = 10,000 – 2,500 or Y*25 = 7,500. Then by dividing both sides by 25 to get Y = 7,500/25 or 300 lbs. This also makes sense based off the size of the Y block in the image. It is always a good idea after a long calculation to step back and use simple logic to make sure your answer makes sense.
