Practice Relating to Rule 29. Medical Transports
Section B. Respect for and protection of medical aircraft
Peru’s IHL Manual (2004) states: “The following classes of enemy aircraft are exempt from attack: … medical aircraft”. 
Peru, Manual de Derecho Internacional Humanitario para las Fuerzas Armadas, Resolución Ministerial Nº 1394-2004-DE/CCFFAA/CDIH-FFAA, Lima, 1 December 2004, § 129.d.(1).(a); see also § 87.a and b.
The manual further states:
Medical aircraft are exempt from attack only if they:
(1) have been recognized as such;
(2) are acting in compliance with an agreement; parties to the conflict are encouraged to notify medical flights and conclude agreements at all times, especially in areas where control by any party to the conflict is not clearly established; when such an agreement is concluded, it shall specify the altitudes, times and routes for safe operation and should include means of identification and communication;
(3) fly in areas under the control of own or friendly forces;
(4) fly outside the area of armed conflict.
In other instances, medical aircraft operate at their own risk. 
Peru, Manual de Derecho Internacional Humanitario para las Fuerzas Armadas, Resolución Ministerial Nº 1394-2004-DE/CCFFAA/CDIH-FFAA, Lima, 1 December 2004, § 129.e.
The manual also states:
Agreements or notifications are required for medical aircraft flying over areas controlled by enemy forces or contact zones.
Medical aircraft may not be used under any circumstances to obtain military information or to search for wounded and shipwrecked persons unless a prior agreement has been made.
Medical aircraft can be inspected. They can be confiscated if the inspection discloses that the aircraft:
(1) is not a medical aircraft;
(2) is being used to gain a military advantage;
(3) has flown without or in breach of a prior agreement.
Aircraft seized in this manner become war booty.
