Hvis QFE ved et skydeområde er på 1030 og skydeområdet går til 16500’, hvad er så den første available FL for VFR eastbound?
1013-1030 = -17 hPa
-17*30 = -510’
16500’-510’ = 15990’
15990+1000’ = 16990’
FL175 er svaret
Hvis QNH er 1010 og TA er 3000’, hvad er så første available FL for IFR og VFR, med min 1000’ sep?
1013-1010 = 3
3*30 = 90’
3000 + 90 = 3090’
IFR FL 50
VFR FL 45
How can you separate horizontally?
Lateral - geographical or by track (example a route or point)
Longitudal - in time or distance
Surveillance
How do you separate vertically?
In feet between aircraft (most often by 1000’)
What is the different procedures of separation?
Procedural (no radar) or Surveillance (radar)
Do you provide separation between all flights in class A and B?
Yes
Do you provide separation between IFR flights in C, D and E?
Yes
Do you provide separation between IFR and VFR in class C?
Yes
Do you separate between IFR to SVFR and SVFR to SVFR, when described?
Yes
Are you allowed as ATC to clear less than the applicable separation minima?
No
Can you as ATS establish other separation minima to areas or locations?
Yes if there are types of aids used or circumstances are different then those covered in ICAO documents
What is vertical separation in RVSM airspace?
1000’ between FL290 and FL410
2000’ above
What is vertical separation in non RVSM airspace?
1000’ below FL290
2000’ above FL290
Is Denmark RVSM airspace? And if so, can we then always separate with 1000’ between FL290 and FL410?
Yes Denmark is, but we can still get aircraft that are non RVSM capable. So in that case we have to separate with 2000’ above FL290
Should you avoid to clear aircraft outside controlled airspace?
Yes
What does Y mean in the flight plan?
Starting IFR and switching to VFR
What does Z mean on the Flight Plan?
Starting VFR and switching to IFR
What is the exceptions to giving a clearance to approve an aircraft into another aircraft level, when aircraft reports leaving?
- severe turbulence
- climb
- difference in performance
- Holdings
You have 25 miles to a crossing of two aircraft and you need to climb one of them 6000 feet to pass the other. Aircraft flying 240 kts.
What rate of climb do you need?
Minimum 5 nm distance = 20 nm to climb
240kts/60= 4 nm/min
20/4 = 5 min
6000 feet / 5 min = 1200 feet/min
What is the definition of time separation?
Aircraft to depart at a specified time, to arrive over a geographical location at a specified time, or to hold over a geographical location at a specified time
What is the cons of using speed control as separation?
It’ll take a long time to separate
What is the same track definition of separation?
45 degrees on same side of the aircraft on both sides
What is the time distance required between two aircraft on same level and same track
15 min
except if you have frequent nav aids to determine pos and speed - then it’s 10 min.
Or 5 min if 20 kts or faster
Or 3 min if 40 kts or faster
What is the time difference between aircraft flying crossing tracks?
15 min if few nav aids
10 min if frequent nav aids
