Differences in the regulations between Parts
Part 121 of the FAA regulations involves the scheduling of air carrier operations to compel individuals to show up in time to catch up with the prearranged flight. However, it is crucial to note that part 121 is a supplemental carrier and does not necessarily maintain regular schedules but instead, its travel plan is for a specific period (Federal Aviation Administration, 2016). Still, the operator has to engage himself/herself in common carriage to allow anybody else to buy tickets. Additionally, part 121 regulates the scheduling of commercial air services with clients who pay for the same and planes are flown more frequently on specific routes as the operator’s wishes. Part 121 majorly deals with regional and major airlines like the SkyWest, Horizon airlines, United Expres, Delta and Alaska Airlines (Federal Aviation Administration, 2016).
Conversely, part 135 states the rules guiding commuter and on-demand flight operations like those of corporate, government, and helicopter ops. Part 135 operation specifications are applicable to helicopter pilots regardless of whether they fly cargo or haul passengers. A commuter is a scheduled operation that involves at least 5 round trips on a weekly basis between two or more terminuses in accordance with the recommendations of the published flight schedule. Therefore, their size allows them to fly the utmost 9 passengers or 7, 500 or fewer pounds of cargo. However, the on-demand flight operations under part 135 involve the act of flying the affluent wherever they desire to go at any time depending on their needs (Federal Aviation Administration, 2016). Customers can call up helicopters or airplanes when in need based on a per se schedule. A typical example is the air ambulance operation out of Alaska that target almost the same destination though it is not always a set schedule because it wholly depends on the patient needs.

Furthermore, part 91 of the FAA Regulations has distinct features that make it different from the two parts explained above. For example, it is usually owner-operated like those of the Coca-Cola Company consisting of roughly a fleet of 30 jets. Therefore each one of the company’s employees and invited guests can get a free ride on the aircraft. This means that the company maintains the private carriage status and limits the number of private contracts to less than 3. Note that the passengers must not pay for the flight unless they are government officials on a government mission in accordance with the guiding principles of “public use” (Electronic Code of Federal Regulations, 2018).
By definition, part 91 of the FAR details the comprehensive operating and flight rules specifically for civil aircraft. Regardless of the plane size, both Cessna 182 and Boeing 777 must comply with the principles of this part, and the policymakers must ensure that the legislation is non-commercial. Therefore, there is neither reimbursement nor compensation for the services involving the carriage of passengers. Part 91 further requires passenger identification checks for the case of charter flights though this is not necessary if the trips are within the US (Electronic Code of Federal Regulations, 2018).
Why the differences in the regulations are justified in regard to maintaining aviation safety
The differences in regulations depicted in the previous paragraphs are very important in providing the general aviation safety. For instance, flying passengers in compliance with part 135 regulations ensure that the crew rests well to avoid fatigue that can lead to a general lack of concentration. Similarly, the part 91 regulations prioritize rests and allow for take-off in environments of zero visibility (Electronic Code of Federal Regulations, 2018). Also, part 135 ensures that all aircraft under its operation schedule must use terminuses with on-site weather reporting to avoid probable risks. Therefore, part 135 further provides the safest and most reliable private jet services across the US and other western countries (Federal Aviation Administration, 2016).
