Study Notes

Air Navigation Regulations Summary

For RNP APCH-LNAV/VNAV, RNP APCH-LPV, or precision approach procedures, the minimum visibility must not be below the highest of specified RVR/visibility, AFM minima, or operator's manual minima.
For RNP APCH-LNAV/VNAV, RNP APCH-LPV, or precision approach procedures, additional visibility requirements apply under specific conditions, including inoperative approach lighting systems and aircraft equipment limitations.
Minimum altitude for RNP APCH-LNAV, RNP APCH-LP, or other NPA must not be below the highest of MDA/MDH on the instrument approach chart, relevant AFM minima, or operator's manual minima.
For RNP APCH-LNAV, RNP APCH-LP, or other NPA, the minimum visibility must not be below the highest of specified visibility, AFM minima, or operator's manual minima, with additional provisions for inoperative approach lighting systems.
Specific altitude requirements apply when conducting circling maneuvers, depending on the highest of circling minimum altitude specified, relevant AFM minima, or operator's manual minima.
When conducting circling maneuvers, specific visibility requirements apply, depending on the highest of circling minimum visibility specified, relevant AFM minima, or operator's manual minima.
Missed approach procedures are detailed, including standard procedures and requirements related to GNSS, RAIM warnings, and loss of visual reference during circling.
Straight-in landing is not permitted unless circling approach can be conducted in specified weather conditions or better.
Specific procedures are outlined for go-arounds and missed approaches in visual meteorological conditions (VMC), including initial climb and awaiting ATC instructions.
Aircraft must carry out published instrument missed approach procedure if unable or not willing to land from an instrument approach in VMC, unless directed otherwise by ATC.
The text includes references to AIP ENR 1.5, Jepp TERMINAL, and other relevant documents for further details on missed approach procedures and requirements.
Key acronyms include RNP APCH, LPV, AFM, MDA, MDH, RVR, VMC, and ATC.
