VOLUME I Multinational Maritime Tactical Instructions and Procedures

estimated time of departure (ETD). The time of passing the entrance to the harbor (passing
breakwaters), or, when point A is established, the time of passing point A. For aircraft, it is the
time of departure from an airfield, target, CPA station, and so forth.
evaluation. The appraisal of threat information to determine the type and degree of threat.
evasion. A change in the planned route or speed (but not the destination) of a force, convoy, or independent,
usually ordered by the OTC for tactical reasons.
evasion course. When a ship is too close to the actual area of deposition and escape course is not
always the safest solution.
1. Ship’s speed is greater than effective downwind speed, ship steers away from fallout axis,
and maintains actual distance to area of fallout deposition; therefore, the relative course of the
ship should be 90º away from fallout axis.
2. Ship’s speed is less than effective downwind speed, ship steers to be as far away as possible
from fallout axis, whenever the outer (forward) limit of fallout deposition arrives at the ship’s
position.
extended maneuvering interval. The standard maneuvering interval, plus 500 yards, unless otherwise
ordered, to allow for station-keeping errors.

fighter engagement zone (FEZ). The airspace beyond the cross-over zone out to limits as defined
by the OTC, taking into account the fighter’s combat radius and effective weapon range.
final diameter. The diameter of the circle that would ultimately be described by a ship turning
through 360º with a constant rudder angle.
fleet. An organization of ships, aircraft, Marine forces, and shore-based activities all under the command
of a commander or a commander-in-chief who may exercise operational as well as administrative
control.
fleet air wing. An administrative or tactical organization consisting of two or more squadrons of aircraft.
flex deck. CV operation where unscheduled, continuous launch and recovery of aircraft is made possible.
flight. Any number of aircraft, regardless of type (fixed-wing or helicopter), proceeding in company
on a common mission or to the same destination.
flight levels. Surfaces of constant atmospheric pressure which are related to a specific pressure datum,
1013.2 mb (29.92 in), and are separated by specific pressure intervals. (Flight levels are
expressed in three digits that represent hundreds of feet; e.g., flight level 250 represents a barometric
altimeter indication of 25,000 feet and flight level 255 is an indication of 25,500 feet.)
flight operations course and speed. The course and speed used by a ship when launching or recovering
aircraft.
flotilla. An administrative or tactical organization consisting of two or more squadrons together with
such additional ships as may be assigned as flagships or tenders.
force. A general term for the ships and aircraft under the orders of an OTC, including friendly direct
support submarines.
