such applications. Within the same period all resident pilots and owners
and/or operators of all aircraft shall register the federal licenses of said
airmen and of said aircraft in such manner as the Commission may by
regulation prescribe. All proposed airports, lauding fields, air schools,
flying clubs, air beacons, or other air navigation facilities shall first be ap-
proved by the commission before they or any of them shall be so used or
operated. It shall be unlawful for any airport, landing field, air school,
flying club, air beacon, or other air navigation facility to be used or oper-
ated without the approval of the commission, provided, however, that no
license, rule, order, or regulation promulgated under the authority of this
section or of this entire act shall apply to airports, landing fields, air
beacons, air markings, or other air navigation facilities owned or operated
by the Government of the United States or by this state. The commission
is hereby authorized to issue a certificate of its approval in each case and
to make the following charges therefor:

For the issuance of each certificate of registration of each federal license
for pilots and aircraft, no fee shall be charged.

For issuance of each four year airport license, no charge.
For issuance of each four year landing field license, no charge.
For issuance of each four year air school license, no charge.
For issuance of each annual flying club license, no charge.
For issuance of each four year air beacon license, no fee shall be charged.
For issuance of each four year other air navigation facility license, no
fee shall be charged.

Upon application by any applicants for a license for an airport, landing
field, air school, flying club, air beacon or other air navigation facilities
the Commission may refuse to grant such license to said applicants when
said Commission has reasonable grounds to believe, based on public health,
public morals, public safety and public welfare, that the granting of any
of said licenses to any of said applicants would endanger or be detrimental
to the health, morals, safety or welfare of inhabitants of this State. Upon
application by any applicant for a license for an airport, landing field,
air school or air beacon not heretofore used or operated, applicant shall
post a conspicuous notice on the property affected, thirty days before ap-
plying for said license, and said notice shall set out the use for which the
said license is asked and the date of the said application.

In any case where the commission rejects an application for permission
to operate or establish an airport, landing field, air school, flying club, air
beacon, or other air navigation facility, or in any case where the commis-
sion shall issue any order requiring certain things to be done, it shall set
forth its reasons therefor and shall take the requirements to be met before
such approval will be given or such order modified or changed. In any
case where the commission may deem it necessary it may apply to a court
of equity to order the closing of any airport, or landing field, or to order
any air school, flying club, or air beacon, or other air navigation facility
to cease operations until it shall have complied with the requirements laid
