Sustainable Usage of Freight Drones in City Centers, Proposition of Regulations for Safe Usage of Drones
Round 1
Reviewer 1 Report
Thank you for the opportunity to review your paper. I agree that the most important usage of drones is the safety conditions in the COVID-19 era.
But words, expressions, and composition in this paper are not the way to write a paper, but a way to write an essay or newspaper article. So, a general revision of the content is required.
In the Abstract, the background and objective of the study, the results of the study, and technological, academic, and social contribution should be described. Especially, it has not been precisely explained why the development of drones is important.
"1. Introduction” should be added to write the research background and purpose using more than 10-20 references, and the specific research method and procedure should be explained step by step.
In “1. The Freight Drone”, “2. Usage of The Drones in The City Center”, and “4. The Safety Problems of Freight Transport in Urban Area by Drones”, several references should be cited.
Figure 1 is not professional and does not contain sufficient content, and it is better to use more specific images or real photos.
It is necessary to explain abbreviation such as RPAS and DGTA.
In “3. In the Review of the Law Regulation about the Usage of the Drones “, a comparative review of the current situation in Austria, Belgium, Canada, Ireland, Netherlands, and Poland should be made, and the analysis obtained through the comparative review should be prepared. It is better to express these using tables and figures.
The law regulation of “5. The law regulations of “Propositions for Law Regulations for Safety Usage of the Freight Drones” should be tabulated and the rationale for proposing them should be logically described.
Figure 2 should be sharper and better aligned.
“Conclusion” should be added as one chapter, and the research results obtained through this study, future research, and technical, academic, and social contribution should be described.

Reviewer 2 Report
The content of the article corresponds to the topic raised in the title. The literature used for the topic of the survey is topic specific, but rather narrow, it lacks several literature relevant to its topic. International positive examples are rather negligible. In particular, his writings lack UTM (Unmanned Aircraft / Aerial System Traffic Management) systems, which are currently active in the world, and which can guarantee the safe, efficient and predictable integration of drones into the airspace of each country. For example, the NASA-UTM system in the United States, the U-space system in the European Union, the UOMS (Civil UAS Operation Management System) in China, or JUTM (Japan UAS Traffic Management Consortium) introduced in Japan.
Another important issue for the topic of the article that is not currently addressed in the article is the issue of BVLOS (Beyond Visual Line of Sight). Currently, the biggest obstacle to the faster and greater proliferation of drones is the time-consuming, cumbersome nature of defining rules, restrictions, and standards related to BVLOS (Beyond Visual Line of Sight) flights. Therefore, the use of out-of-sight flights (BVLOS) plays an unavoidable role in drone propagation, however, these types of operations require a high degree of traffic management in a fundamentally automated environment.
Legislation on drones should, in principle, facilitate the safe implementation of existing drone traffic management systems. The rapid proliferation of Unmanned Aircraft (UAVs) poses a number of opportunities and challenges for various stakeholders, be they Air Navigation Service Providers (ANSPs) working on the safe insertion of equipment into airspace or small and medium-sized aircraft. medium-sized businesses, who want to use drones for business purposes to put their operations on a new footing.
In areas with significant potential, such as infrastructure, transportation, object protection, the activities and opportunities are greatly influenced by the environment and framework that currently supports gaps, is not understood and transparent, and in some cases even does not exist. Creating a complete ecosystem that meets all needs requires meeting a number of expectations that require a one-way attitude and commitment from all actors involved.
The bibliography used is in sync with the references in the text, the same number of literatures are included in the bibliography as indicated in the text. The figures in the article are expressive, supporting the point well.
It would be necessary to provide a brief but comprehensive picture of the global drone segment, with particular reference to the systems related to their traffic management. Furthermore, it would be expedient today for the rules and restrictions related to BVLOS (Beyond Visual Line of Sight) flights, which hinder the spread of drones the most.

Round 2
Reviewer 1 Report
Authors have made some modifications, but in Abstract, the background and purpose of the study, the results of the study, and the technical, academic, and social contribution have not been described yet. It has not been precisely explained why the development of drones is important.
And still “1. Introduction” was inserted and more than 10 references were used to write the research background and purpose, and the specific research method and procedure were not explained.
In order for Figure 1 to be professional and to include sufficient content, the figure needs to be marked for explanation. And it is necessary to review whether the photo can be cited.
It is necessary to review sentences such as overall uppercase/lowercase letters, punctuation marks, and spacing. For example, in Line 48, one period must be deleted from the sentence of “In Austria since 01.01.2014 the drones are under strict laws regarding flying. .”.
In “3. Review of the Law Regulation about the Usage of the Drones”, the purpose of reviewing the laws and regulations of various countries and the analysis results obtained after the review should be added. The paper should not be concluded by simply listing examples.
The rationale for proposing the laws and regulations of “5. Propositions for Law Regulations for Safety Usage of the Freight Drones” has not yet been logically described.
It is better to modify ‘7. Summary’ to ‘7. Conclusion’.

Dear Reviewer.
Thank You for all Your comments.
I would like to answer them.
In the introduction, I wrote that this paper doesn’t concentrate on the construction of drones but law regulations of usage of them. I add some words more.
For Figure 1, I changed the place in the text where this picture is cited. I hope that now is good.
You was right, overall uppercase/lowercase letters, punctuation marks, and spacing needed correction.
In “3. Review of the Law Regulation about the Usage of the Drones”, I did suggestions from former opinion. I made a table and I add a comment below it.
In 5. Propositions for Law Regulations for Safety Usage of the Freight Drones, below I commented it. The law regulations are based on conclusions of accidents or other causes. Here are propositions that may be changed. I wrote in the introduction that I expect discussion about this subject as uniform law base.
In 7, I changed from Summary’ to ‘7. Conclusion’.
I hope that modification is satisfactory for You.
Thank You again for your review.
As said Napoléon Bonaparte: only he does not make mistakes, who does nothing ?
I hope that now the paper will be accepted for publishing.
