Instrument Approach/Take-off Procedures Flashcards
When may an aircraft fly in a no-circling area?
Only by day VMC. (Jepp Term: AU-15)
Do instrument approach and take-off charts depict tracks or headings?
Tracks. Correction for wind must be made. (Jepp Term: AU-15)
Are times specified on approach charts fixed times?
Yes. The only adjustment that can be made is for wind corrections. (Jepp Term: AU-15)
How much obstacle clearance do the 25nm and 10nm MSA’s provide for?
1000ft (Jepp Term: AU-15)
Can an aircraft manoeuvre within the 10nm and 25nm sector MSA’s?
Yes as long as it is maintained above the MSA. (Jepp Term: AU-15)
When may an aircraft descend below the route LSALT or MSA?
- When on a visual approach
- When established on a DGA
- When being radar vectored
- When established at the IAF or overhead the aid. (Jepp Term: AU-15)
What are the aircraft performance speeds?
Cat A: up to 90kts Cat B: 91 - 120kts Cat C: 121 - 140kts Cat D: 141 - 165kts Cat E: 166 - 210kts (Jepp Term: AU-15)
Can an aircraft reduce its category due to reduced operating weight?
No. It must however increase its category to the next higher one due to actual handling speeds. (Jepp Term: AU-16)
What are the handling speeds for a CAT B aircraft?
Initial and intermediate: 120 - 180kts
Max speed for reversal: 140kts
Final approach: 85 - 130kts
Max speed for circling: 135kts
Max for missed approach: 150kts (Jepp Term: AU-16)
What are the handling speeds for a CAT C aircraft?
Initial and intermediate: 160 - 240kts
Final approach: 115 - 160kts
Max speed for Circling: 180kts
Max for Missed approach: 240kts (Jepp Term: AU-16)
If there is no FAF on a reversal procedure, when must the final approach speed be achieved by?
Before descending on the inbound track. (Jepp Term: AU-16)
What does OCA stand for and mean?
OCA is the obstacle clearance altitude and is equal to MDA or DA on a precision, non-precision or circling approach. (Jepp Term: AU-16)
If the glide path on an ILS approach fails, may the approach be continued?
The approach may be continued using the LLZ procedure for that rwy. (Jepp Term: AU-17)
If the markers or NDB on an ILS approach fail may the approach be continued?
Yes, as long as other check heights as specified on the chart or NOTAMS are withheld. (Jepp Term: AU-17)
If the GBAS on a GLS approach fails may the approach be continued?
No. (Jepp Term: AU-17)
If during the ILS or GLS approach an unexplained discrepancy is noticed at the altimeter check height, may the approach be corrected and continued?
No, a missed approach must be conducted. (Jepp Term: AU-17)
What is an ILS critical area?
An ILS critical area is an area around the ILS installation on the ground which during certain weather conditions is protected by ATC from aircraft and other ground vehicles. (Jepp Term: AU-17)
What weather conditions need to be met for ATC to actively protect the ILS critical area?
A cloud base of less than 600ft and a visibility of less than 2000m. (Jepp Term: AU-17)
Why are ILS critical area established and protected?
Interference from aircraft and other ground vehicles may disturb or reflect the ILS signals causing track variations for an aircraft in flight during the approach. (Jepp Term: AU-17)
May an aid on the same airport but not specifically identified for use on the approach chart be used for an instrument approach?
No. (Jepp Term: AU-18)
At what angle are non-precision approaches usually designed?
The minimum angle of descent is 3 degrees (5.2%). Higher angles may be used where required. (3.77 degrees (6.5%) for CAT A and B; 3.5 degrees (6.1%) for CAT C and D) (Jepp Term: AU-19)
During an GPS/RNAV approach, may an aircraft track directly to the intermediate fix?
Yes, as long as the resulting change in track is not greater than 45 degrees. (Jepp Term: AU-19)
When can you descend to the next limiting altitude on an approach that has altitude limitations?
Once you have passed the point where the next altitude restrictions starts and the aircraft is established on track. (Jepp Term: AU-21)
When does the final segment commence on approaches that have no specific FAF?
The final approach segments commences at the completion of the reversal procedure. (Jepp Term: AU-21)
