ATT1810 Non-radar Flashcards
What is non-radar separation based on?
Assigning a block of airspace to each aircraft, and never let blocks overlap.
How wide is an airway?
4 miles each side, total of 8 miles.
Beyond 51 miles, it gets bigger.
Name the 4 types of separation
Vertical, Lateral, Longitudinal, Visual
The presumption in non-radar is that you do NOT have separation unless…
You can prove you do
Altitude wise, what is a pilot required to report?
Leaving an old assigned altitude for a new assigned altitude.
What is the strip marking for telling an aircraft to report reaching or report leaving an altitude?
Report reaching - RR
Report leaving - RL
A single line through an altitude means…
The aircraft reported leaving that altitude
What would you compare a flight progress strip to?
A legal document
You can step an aircraft up to a vacated altitude if the lower aircraft ……
Has the same or slower climb rate as the higher aircraft.
What are the 4 exceptions to stepping up or down?
Severe Turbulence
PD (pilot’s discretion) clearance
Air refueling
Any other time the controller thinks it might not be safe
Lateral separation is
Aircraft are on airways or holding patterns that do not overlap
What do you call the problem between using DME and RNAV or GPS together?
Slant range
To use DME and RNAV/GPS at the same time you must be…
Beyond 10 miles of the VOR or under 10,000 feet
A degree divergence chart is used to figure when 2 crossing airways begin or end their overlap. What is the minimum degree divergence to use the chart?
15 degrees
Longitudinal separtation is…
Separtation on the same route at the same altitude
Standard longitudinal separation is how many minutes or miles?
10 minutes or
20 miles
Reduced longitudinal separation can be used if the lead aircraft is how much faster (2 different speeds), and what are the new separation requirements?
22 Knots - 5 minutes or 10 miles
44 Knots - 3 minutes or 5 miles
What type of speeds are the 22 knot and 44 knot rule based on?
True air speed
If the lead aircraft is descending, or the following aircraft is climbing (with no overtake in speed), what can separation be reduced to?
5 minutes or 10 miles
Opposite direction aircraft must be at different altitudes from when to when?
10 minutes before to 10 minutes after they are estimated to pass.
If two aircraft WITHOUT DME report the same fix, when can you let one go through the other’s altitude?
3 minutes after second one reports
If two DME or RNAV aircraft report the same fix, when can you let one go through the other’s altitude?
Immediately
