4. Security Measures.
a. AR 190-11 will be applied when an aircraft has weapons and/or ammunition aboard. Aircrafts
with weapons and/or ammunition aboard must be provided constant surveillance.
b. A manufacturer approved security device will be used to secure an idle Army aircraft. A
modified work order approved ignition security and door security device will be used. Emergency
aircraft and aircraft undergoing maintenance with duty personnel present are exceptions. Aircraft used
in a tactical exercise are also exceptions.
c. Lock and key control procedures must be included in the physical security plan, and they must
be strictly followed. A master key or common key is prohibited on aircraft and hangars. Such a key is
also prohibited on structures sheltering aircraft or their components.
d. The aviation physical security plan should include ID and movement control. Access to an
aircraft can thereby be determined.
e. Privately owned vehicles are prohibited from flight line area and aircraft parking area. The only
exception occurs when authorized by the airfield CO.
f. Unauthorized usage of some items would circumvent security measures. Such items will be
secured during nonduty hours. These items include the following:
(1) Auxiliary power units (APUs).
(2) Vehicle tugs.
(4) Aircraft boarding ladders.
5. Security Education. A formal security education program for employees is greatly beneficial. It will
aid in minimizing threats to aircraft and aircraft components. A security briefing should be given all new
employees, and a reinforcement of security awareness for all employees should be done periodically
each year. Several methods could be used to emphasize support of security plans. Handouts, policy
letters, and formal briefings are examples.
6. Physical Security Measures. Level II.
a. Construct a perimeter barrier and a patrol road or path. Build these around the flight line,
parking ramps, pads and areas; build them around hangars, and other critical facilities. Erect protective
lighting at outside aircraft parking sites.
