Jeppesen/ERSA Theory Flashcards
(69 cards)
What are the RVSM flight levels, and how much separation is provided?
FL290-FL410
1000ft Separation between RVSM approved aircraft
What does a declaration of MINIMUM FUEL mean?
It is not an emergency declaration, but is an indication that if any further delay occurs an emergency situation may result.
What does an RNP Value represent?
A containment value in nautical miles from the intended position in which the aircraft must be within 95% of the time
What is the difference between RV & RVR values?
RV = Runway Visibility = Human derived RVR = Runway Visual Range = Instrument derived
What does calling ‘Visual’ imply for ATC?
Indicate acceptance for responsibility to see and avoid obstacles when operating below MVA/MSA
For En-route displayed LSALTs what RNP is this based on?
RNP 2
In regards to LSALT calculations, what height of obstacles are considered?
Unreported obstacles may exist up to 360ft, so the min LSALT is 1360ft above the highest elevation, but if the highest elevation is below 500ft, a min LSALT of 1500ft applies
If ATC advise ‘Resume Normal Speed’ which speed does this cancel?
Only the previously issued ATC speed restriction, Airspace & STAR restrictions will still apply following this.
Wont be used if already complying with a published speed limitation Resume Published Speeds would be said
If ATC advise ‘No Speed Restrictions’ which speeds does this cancel?
All airspace and ATC speed restrictions
Note* this will not be used whilst conducting a STAR or SID where published speeds exist
Aerodrome forecasts are issued for weather within what distance?
5nm from the ARP (Aerodrome Ref Point)
In a METAR or SPECI and 360V090 (for example) is shown, what does this mean?
The wind has varied between 360-090 in the 10min sample period, this will only show when winds vary by over 60degrees.
When visibility is shown in a METAR/SPECI as (for example) 6000m 700S, what does this mean?
The prevailing visibility is 6000m, and 700m Vis to the south (only shown when min vis less than 5000m)
When a SPECI indicates R16/0900U, what does this indicate?
The RVR indicates 900m Vis in an upward trend (improving), averaged over the 10min reporting period
U - Upward Trend, D - Downward Trend, N - Nil Change
When a SPECI indicates R16/0900V1200, what does this indicate?
That RVR is varying greatly over the reporting period, the first figure (900m) indicates 1 minute mean min vis, (1200m) indicates 1 minute mean max vis
When a SPECI indicates R16/P2000, what does this indicate?
The RVR is 2000m (or more), which is greater than the instrument can measure, and gives the maximum value that can be assessed
When a SPECI indicates R16/M0100 what does this indicate?
The RVR is 100m or less, this is the lowest value that can be assessed by the instrument.
At what percentage probability will thunderstorms or reduced visibility periods be included in the main body of the TAF?
Over 50% probability, if not PROB30 or PROB40, if below 30% this will not be included.
If a SPECI indicates VV010, what does this indicate?
A vertical visibility of 1000ft. This is commonly used when thick smoke is present. The VV is the ‘equivalent’ to an overcast cloud layer when practically planning for approaches.
A GPWT chart shows 25120-50 what does this show?
Wind 250degrees at 120kts, Temp -50
On RSWT (Route Sector Winds & Temps) chart, what does 340-42 2505545 Indicate?
At FL340, ISA is -42degrees
Wind is 250/55, Temp is -45 (ISA-3)
What time can ELTs be tested, or if an ELT is heard during this time testing might be assumed?
Within the first 5mins of the hour, and only 5 seconds in duration.
Unless tracking via SID or instructed by ATC, when is the departure track required to be intercepted?
Within 5nm of departure aerodrome
What requirements do ATC require to issue an aircraft with a Visual Approach Clearance? (BY DAY)
- Within 30nm of aerodrome
- Pilot has established and can maintain visual reference with ground/water to the aerodrome.
- Visibility not less than 5000m
What requirements do ATC require to issue an aircraft with a Visual Approach Clearance? (BY NIGHT)
- Pilot has established and can maintain visual reference with ground/water to the aerodrome.
- Visibility not less than 5000m
- Aircraft within 30nm or if A/C is being vectored at the MVA given a heading to intercept final
