1. Explain relative humidity and latent heat. For instance, the article titled “Principles of heat and humidity in the airway” by Fisher & Paykel Healthcare Limited infers that the quantity of water vapor per liter of gas, as compared to the maximum amount the gas may store, is known as relative humidity (RH). This indicates that a percentage figure is always used to express it. Temperature affects a gas's capacity and, by extension, its RH. More water vapor can be in warmer gasses (n.d, 2024, para. 3). This indicates that the amount of water vapor present at the current temperature may be determined using this specific term. For example, the article titled “latent heat” by The Editors of Encyclopædia Britannica states latent heat is the energy that a substance absorbs or releases when going through a phase shift without experiencing a temperature change. The latent heat that results from vaporizing a liquid or solid or condensing a vapor is referred to as the heat of vaporization; the latent heat involved with dissolving a solid or freezing a liquid is known as the heat of fusion (n.d, 2023, para. 1). In reading the FAA Aviation Weather Handbook gives an understanding that latent heat mainly happens due to the Earth’s surface absorbing radiation. When radiation is being produced the effect the production of heat that water in lakes, rivers, seas, soil, and vegetation is evaporated. Water even condenses into tiny water droplets as a result of this, or it accumulates as ice crystals which are visible as clouds. This type of example helps to visualize how latent heat works and to better understand what it implies in the field of aviation. 2. What did you learn from the topic on heat imbalance variations with latitude? On the topic of heat imbalance variations with latitude, I have learned that the Earth can absorb solar radiation differently due to the changes in latitudes. For instance, the article titled

“Solar Radiation & The Earth’s Energy Balance” by Dawn Wells informs that the average amount of solar power that enters a square meter worldwide is 340, however, solar illumination varies over time and space. The annual amount of solar radiation varies dramatically from tropical to arctic latitudes. At moderate and high latitudes, it varies greatly from season to season as well (Wells, 2016, para. 13). Due to the Earth's axis the radiation will be different as well as the seasons. The heating imbalance for the same year will display different season reports due to the sun's orbit on the Earth. 3. Read the two articles below. Discuss how density played a role in the accident and overrunning the runway. For example, the article titled “Flying too low likely caused newlyweds’ fatal plane crash in Telluride” by Jim Mimiaga states that the fight accident report from the NTSB inquiry concluded that the aircraft crashed due to the pilot's loss of control during climb to cruise flight, exacerbated by crossing mountainous terrain without ascending to a higher altitude. The report highlighted a density height of 13,604 feet near the crash site, impacting the airplane's ascent performance, with no noticeable turbulence (Mimiaga, 2023, para. 8). From this finding we can tell that the aircraft didn’t have the right condition the climb to a higher altitude due to the thin atmosphere reducing the airplane engine power. On the other hand, the article titled “The Many Factors That Lead to Runway Overruns” by Meg Godlewski infers that there are many ways in which could cause a runway overrun. Additionally, elevated airports with large densities might result in elevated ground speeds, which in turn can cause runway overruns (Godlewski, 2023, para. 12).
