Passenger officers should call on the captain of the ship. If there are many, they should choose a calling committee and consult the executive officer as to a convenient time to call. The latter will make arrangements with the captain.

Gun salutes in the Navy are the same as in the Army, except that flag officers below the rank of fleet admiral or general of the Army are, by Navy regulations, given a gun salute upon departure only. By Army regulations gun salutes for the same officers are fired only on arrival.

The rules governing saluting, whether saluting other individuals or paying honor to the color or National Anthem, are the same for the Air Force as in the Army, with the minor exceptions already noted. Because a most frequent contact between the Air Force and the other services comes of the operations of air transport, an officer should know what is expected of him when he travels as a passenger in military aircraft.

It is assumed that the majority of officers visiting an Air Force base will arrive by air at the local military airfield. In addition to the Base Operations Officer, who is the commander's staff officer with jurisdiction over air traffic arriving and departing, the Airdrome Officer is charged with meeting all transient aircraft, determining their transportation requirements, and directing them to the various base facilities. General officers and admirals will usually be met by the Base Commander if practicable. RON (Remaining Over Night) messages may be transmitted through Base Operations at the same time the arrival notice is filed.

Pilots of transient aircraft carrying classified equipment are responsible for the safeguarding of that equipment unless it can be removed from the aircraft and stored in an adequately guarded area. Under unusual circumstances, it may be possible to arrange for a special airplane guard with the base commander.

Passengers from other services, who desire to remain overnight at an air force station should make the necessary arrangements with the Airdrome Officer, and not attach themselves to the pilot who will be busy with his own responsibilities. By the same token, passengers of other services who have had a special flight arranged for them should make every effort to see that the pilot and crew are offered the same accommodations that they themselves are using, unless the particular base has adequate transient accommodations.

Passenger vehicles are never allowed on the ramp or flight line unless special arrangements have been made with the Base Operations Officer; this permission will be granted only under the most unusual circumstances.

The assigned first pilot, or the airplane commander, is the final authority on the operation of any military aircraft. Passengers, regardless of rank, seniority, or service, are subject to the orders of the airplane commander, who is held responsible for their adherence to regulations governing conduct in and around the aircraft. In the event it is impractical for the airplane commander to leave his position, orders may be transmitted through the copilot, engineer, or flight clerk, and have the same authority as if given by the pilot himself.

The order of boarding and alighting from military aircraft—excluding the crew—will vary somewhat with the nature of the mission. If a special flight is arranged for the transportation of Very Important Persons, official inspecting parties, or other high ranking officers of any service, the senior member will enter first and take the seat of his choice, unless the aircraft is compartmented otherwise. Other members of the party will enter in order of rank, and precedence among officers of the same rank will be determined among the officers themselves. In alighting from the aircraft, the senior member will exit first, and the other members of the party will follow either in order of rank, or in order of seating, those nearest the hatch alighting first. The duties of the crew preclude their acting as arbiters in matters of precedence, and order of boarding and alighting will be decided among the members of the party.

In routine flights, officers will normally be loaded in order of rank without regard for precedence, except that any VIP will be on- and off-loaded first; in alighting, officers will leave as they are seated from the exit forward—officers seated near the hatch will debark first, and so on to those who are seated farthest forward. In the event civilian dependents are being carried, or an enlisted man accompanied by dependents, they will be loaded after any VIP and before the officers, and leave in the same sequence.
