AIP ENR 1.5 Flashcards
If your aircraft falls within 2 performance categories, what speed determines landing minima?
1.2.1
Vat (speed at threshold)
How is Vat (speed at threshold) calculated?
1.2.1
Vs0 x 1.3, or Vs1 x 1.23 (both V speeds are based on the aircraft in landing config at MLW), whichever is higher.
If an aircraft’s speeds fall into two categories, which category must the aircraft be operated under?
1.2.2
The higher category
Can you operate an aircraft with reduced operating weight in a lower category?
1.2.2.a
No, your performance category is based on MLW
When can you descend below LSALT?
1.4
- Visual approach
- DME/GNSS arrival
- Radar vectors
- IAP
- MSA
When can you enter a no circling area?
1.6.2.b
In VMC by day
When must you conduct a missed approach?
1.9.1
- Outside tolerance during the final segment of an IAP
- Suspect or failed navaid below the MSA on an IAP
- Loss of RAIM, or RAIM warning after passing the IAF
- Not visual by the MAPt or DA/DH
- A landing cannot be effected and you cannot circle
- Visual reference is lost while circling to land
What are the limitations to using IAP chart spot heights to survey obstacles for visual circling?
1.6.5
- They do not necessarily show the highest terrain
- They do not necessarily show all obstacles in the circling area
- The chart may not cover the entire circling area
While circling to land, when may you descend below the circling MDA?
1.6.6
- Remain within the circling area
- Maintain visbility along the flight path not less than the circling minima
- Maintain visual contact with the landing runway environment
- By night, when you can descend to the runway with a continuous and normal rate, and conduct normal manoeuvres, to maintain the relevant obstacle clearance for the aircraft’s category
- By day, maintain visual contact with obstacles along the flightpath and maintain the relevant obstacle clearance for the aircraft’s category until aligned with the runway
What is the minimum obstacle clearance for a CAT A and B aircraft during visual circling?
1.6.6 Note 2
300ft for both
What is the size of the circling area for CAT A and B aircraft?
1.6.6 Note 3
CAT A - 1.68NM
CAT B - 2.66NM
What is the maximum angle an NPA can be offset from the runway for CAT A and B aircraft?
1.7.3
30°
On a non-runway-aligned IAP, when can you manoeuvre to align with the runway?
1.7.4
- Within the circling area
- Maintain visual reference with the runway environment
- In sight of ground or water
What is the obstacle clearance and climb gradient for a missed approach procedure?
1.9.1 Note 2
100ft at 2.5% from the MAPt or DA/DH
What is the formula for raising the IAP minima due to reduced climb gradient?
IFR Flight Test Notes
(MSA-MDA)-((MSA-MDA)x(OEI/2.5))
What should your first action be when commencing a missed approach before the MAPt?
1.9.2
Fly to the MAPt
How should you conduct a missed approach from visual circling?
1.9.3
Initiate a climbing turn to overhead the runway and then manoeuvre the aircraft to join the published missed approach procedure
Can you use GNSS to fly a missed approach after it gives a RAIM warning?
1.11.2
Yes, provided the RAIM warning ceases when the missed approach is activated
What restrictions are there with regards to altitude when on a visual approach?
1.14.5
You may not climb above a level you have reported to ATC as having left or that you are maintaining
How close must you be to the aerodrome, and at what height must you be, to commence a visual approach by day?
1.14.6.a
30NM, and above LSALT or MSA
What are the minimum atmospheric conditions required for a visual approach?
1.14.6.a
- Clear of cloud
- In sight of ground or water
- 5,000m visbility
