Company Minima Flashcards
What is a precision approach?
Approach using precision lateral and vertical guidance.
What is a CAT 1 approach?
DH at or above 200 ft
RVR/CMV at or above 550 mts
What is a Minimum Descent Altitude (MDA)?
A specified altitude in a Non-Precision Approach below which descent must not be made without visual reference.
Requires the addition of 50 ft to ensure it is not transgressed.
What is RVR (Runway Visual Range)?
The range over which a pilot of an aircraft on the center line of the runway can see the runway surface markings or lights.
What is Ceiling (CEIL or CLG)?
The height above ground of the base of the lowest layer of cloud below 20 000 ft reported as BKN or covering more than 5/8 of the sky.
What are the 10 elements of Visual Reference?
- Approach lights (including RAI)
- Threshold
- Threshold Markings
- Threshold Lights (RTHL)
- Threshold Identification Lights (RWYTIL)
- Visual Glide Slope Indicator (PAPI)
- Touchdown zone or TDZ markings
- Touch down zone lights (TDZL)
- Runway Edge Lights (REDL)
- RWY Designator marking
What is the Obstacle Clearance Altitude (OCA)?
The height above the elevation of the relevant runway for establishing compliance with appropriate obstacle clearance criteria.
Indicated by shaded area under steps on NPA.
AIM-J 631 (Approach Segments of an Instrument Approach
Initial approach = 984 ft MOC (approx 1000’)
Intermediate approach = 492 ft MOC (approx 500 ft)
CAT 1 = 200 ft
Circling Approach 295ft OCA (approx 300 ft)
What Approach category is the A320 / A321
Category C
What criteria are used for determining Take Off minima
RVR, RVR/VIS or VIS
CEIL if prescribed by state authority
What criteria are used for determining Approach minima?
Precision
APV
NPA
Circling
What criteria are used for determining Alternate Minima
CEIL and VIS
(Note: CMV can not be used for ALTN minima)
VIS - CMV Conversion
ALS and REDL
REDL only
No Lighting
What are the lowest values of Company Minima for Take off?
What is the take-off minima in case there is no take off alternate?
The approach minima shall be applied
What are the requirements for Full, Intermediate, Basic and NIL Approach minima
What are the ceiling and VIS values for Alternate Minima?
What are the minima for Captains other than Cat 1 Captains?
Normally which RVR is used for take off minima?
Touchdown zone
What about if Take off run starts closer to midpoint (Intersection departure) or no Takeoff RVR is reported?
Midpoint RVR
How about when multiple RVRs are specified for a particular take-off minima?
All RVRs mus be above the relevant takeoff minima
When may an approach be continued regardless of the actual weather?
Beyond Final Approach Fix (FAF) or 1000 ft (AAL)
What is the requirement for landing in case only 1 RVR is reported?
Touchdown zone RVR must be above approach minima
