Separation Flashcards
What is separation?
Spacing of aircraft
What 2 things does separation achieve?
Safe and orderly movement of aircraft
What 2 things is separation applied to?
Aircraft
Protected airspaces
What is block altitude?
A range of altitudes an aircraft is cleared to operate in.
RVSM?
Reduced vertical separation minima.
What does reduced vertical separation minima allow?
Allows 1000’ instead of 2000’ vertical separation above FL290 when applicable.
What is vertical separation?
Vertical distance between aircraft
What is lateral separation?
Lateral distance between aircraft at the same altitude.
What does lateral separation often require aircraft to do?
Operate on:
different routes or in
different geographical regions
What is Longitudinal Separation?
The longitudinal spacing of aircraft at the same altitude by a minimum distance in units of time or miles.
What is the difference between longitudinal and lateral separation?
Lateral: Requires operation on different routes or geographical areas.
Longitudinal: Distance expressed in units of time or miles
What is visual separation?
Aircraft visually avoiding each other.
What is runway separation?
Separation requirements for aircraft operating on the runway.
What is Same Course?
courses whose angular difference is less than 45 degrees.
What is a Crossing course?
courses whose angular difference is between 45 and 135 degrees.
What is an opposite/reciprocal course?
Courses whose angular difference is between 135 and 180 degrees.
Up to what flight level is the vertical separation requirement 1000’?
FL410
Below FL410, what is the vertical separation requirement?
1000’
Between what flight levels is the vertical separation requirement 2000’?
FL410 to FL600
Between flight levels FL410 to FL600, what is the vertical separation requirement?
2000’
Above what flight level is the vertical separation requirement 5000’?
FL600
Above FL600 what is the vertical separation requirement?
5000’
If an aircraft does not have the equipment to allow 1000’ vertical separation, what flight level is it assigned to?
Below FL280 or
Above FL430
Between what flight levels can an aircraft that does not have the equipment to maintain 1000’ vertical separation not level off?
Between FL280 and
FL430
Between the flight levels where it cannot level off, what vertical separation is an aircraft that does not have the equipment to maintain 1000’ of vertical separation required to maintain from other aircraft?
2000’
Within a block altitude, what vertical separation must aircraft maintain?
Standard separation
How many feet of vertical separation is required below an aircraft dumping fuel?
2000’
In Special Use Airspace, what is the vertical separation from the airspace limits required for FL290 and below?
500’
