Flashcards in NZ IFR Deck (41)
With regard to RNP, what is the definition of cross-track error and how does it relate to the navigation accuracy for the procedure?
Cross track error = the RNAV computed flight path and the aircraft position relative to the flight path.
Cross-track error should be limited to half the navigation accuracy of the procedure e.g. RNP1 max deviation 0.5NM
Can a departure with a visual segment be conducted at night?
No, unless the visual segment is to be flown at night and is annotated on the respective chart
What are the requirements for a pilot using a secondary or grass runway for take off for an IFR flight?
The runway has a promulgated IFR take off minimum.
Pilot maintains own terrain clearance until established on the departure procedure
can maintain an adequate climb gradient to ensure obstacle clearance
When departing in an evaluated climb sector, unless otherwise specified, an aircraft on a departure must reach a height of _________ or higher above aerodrome level before commencing a turn.
When departing in an evaluated climb sector, if an aircraft is required to cross through two or more sectors to intercept the departure, what climb gradients applies and when do they apply?
The higher climb gradient applies from take off
You are departing in an evaluated climb sector and the aircraft is required to depart on a radial dividing two sectors one of which is standard 3.3%. The aircraft is required to climb at the higher climb gradient or the lower climb gradient?
The lower sector graident
Calculate the ft per minute requirer to maintain a 4% gradient at 180kts
(GSx1.013 )x gradient= vs
(180x1.013) x 4= 728

How can an aircraft with an approach speed of 90-110kts adjust procedural timing?
2 min may be increased to 2.5
3 min may he increased to 4 min
Can outbound time or DME distances be shortened on an instrument approach?
Yes provided that the wind velocity at different altitudes has been confirmed by an immediately proceeding instrument approach and applicable descent rates can be maintained during final approach
Tracking outbound on an approach which is both time and DME limited, when is the inbound turn started?
At the limit that is reached first e.g. DME or time
What is the terrain clearance on a DME arc?
1000ft over terrain 2.5nm each side of the arc ENR 4.14.3e
When can a pilot descend below DA, DH, MDA?
When using normal descent rates and manoeuvring, within the circling area, with appropriate visibility for the approach, visual reference with
Runway end identifier lights
touchdown zone markings
Runway markings or lights
What is the terrain clearance and required climb gradient on a missed approach?
What are the circling areas radius for
CAT A 1.68
CAT B 2.66
CAT C 4.2
When an aircraft is cleared for an instrument approach under radar, except where otherwise instructed the aircraft may descend to a minimum initial approach altitude of?
Altitude on the:
When an aircraft is not under radar control the minimum initial approach altitude will must be the higher of?
The minimum procedural commencement altitude shown on the instrument approach chart
MSA for the route sector (lower of MSA for the route
VORSEC chart steps
25nm MSA diagram
GNSS approved TAA altitude
When can a pilot make a visual approach?
The pilot specifically states request visual approach
Can maintain visual reference with terrain
The reported ceiling is above the approved initial approach level for the aircraft so cleared or;
The pilot reports at the initial approach level or any time during the instrument approach procedure that condition permit a visual approach and a landing is likely
Conditions required for ATC to broadcast conditions suitable for a visual approach?
Ceiling is 1000ft above the minimum radar vectoring alt or the instrument MPCA
What is a visual arrival?
Pilots continue tracking, minimum alt and dist requirements of the procedure except ATC may amend altitude requirements.
