Lesson 4 Flashcards
Preventing a collision between aircraft is accomplished by separation between _________ and aircraft and _________________.
Aircraft, protected airspace
___________ is the spacing of aircraft to achieve their safe and orderly movement in flight and while landing and taking off.
Separation
In a radar or non radar environment, aircraft can be separated three ways: _______________
Vertically, longitudinally, laterally
______________ is the minimum longitudinal, lateral, or vertical distances by which aircraft are spaced through the application of atc procedures.
Separation minima
A ________________ is a level of constant atmospheric pressure related to a reference datum of 29.92 inches of mercury.
Flight level
Longitudinal separation is expressed in ____________.
Miles or minutes
Vertical separation is expressed in _________.
Feet
Type of separation expressed in miles, airways or routes
Lateral
All aircraft operating at or above ____________ shall have the altimeter set at 29.92
18,000 MSL
Aircraft traveling long distances and at higher speeds use 29.92 because ______________.
Impractical to assign new altimeter setting every 100 miles, if aircraft do not use the same setting safety issues arise
If the pressure is low, _____________.
Look out below
If the pressure is high, _______________.
Look to the sky
true or false: vertical separation is the same in radar and non radar environments
True
Basic minimum altitude separation between IFR aircraft:
Up to and including FL410: 1000 ft
Above FL410: 2000 ft
Above FL600: 5000 ft
*non-RVSM aircraft at or above FL290: 2000 ft
*oceanic airspace above FL450 between a supersonic and any other aircraft: 4000 ft
Separation minima increases with altitude because ________ errors are more likely at higher altitudes.
Altimeter
RVSM stands for
Reduced vertical separation minima
Non-RVSM equipped aircraft may only ______ or _______ through RVSM altitudes
Climb, descend
RVSM altitudes are
FL290 to FL410
