What do the new circling minimums take into consideration? Circle to land bank angle limits higher true airspeed at high altitude airports impact of wind on a circle all of the above

What do the new circling minimums take into consideration? Circle to land Protected areas now account for the impact of wind on a circle, bank angle limits, and higher true airspeeds at high altitude airports. Overall they provide a higher margin of safety.

How is it possible to determine whether an approach with circling minimums uses the “new” versus “old” circling minimums? Circle to land It is listed in the airport NOTAMS – best to check them! All circling approaches now automatically apply the new minimums The circling minimums show a black box with a "C" in the middle The approach chart states in the notes whether circling applies the new minimums

Circle to land

When can you descend below minimums on a circling approach? Circle to land As soon as the runway is in view After reaching the missed approach point and confirming that the runway is in sight When the three requirements to descend below minimums have been met

What are the three requirements to descend below minimums? Circle to land Being cleared to land Having at least one of the required visual references in sight (e.g. runway environment) Having required flight visibility Being aligned with the final approach course Being continuously in a position that allows for a normal rate of descent using normal maneuvers to a landing on the intended runway

Do the three requirements only apply to circling approaches? Circle to land Yes No – they apply to all approaches It depends on the approach being flown

Do the three requirements only apply to circling approaches? Circle to land Yes No – they apply to all approaches It depends on the approach being flown

Do the three requirements only apply to circling approaches? Circle to land When you are on an instrument approach, the FAR (14 CFR 91.175(c)(3)) state that you may descend below MDA or DH only if: The aircraft is continuously in a position allowing for normal rate of descent to a landing on the intended runway; The flight visibility is at or above the visibility required to complete the approach; and At least one of the runway environment visual references for the intended runway is distinctly visible and identifiable to the pilot, or The approach light system, except that you may not descend below 100 feet above the touchdown zone elevation using the approach lights as a reference unless the red terminating bars or the red side row bars are also distinctly visible and identifiable.

What Maximum angle of bank is recommended by AIM to use during a circling approach? Circle to land There is no guidance 40 degrees of bank 30 degrees of bank standard rate turns

You are circling to land and lose sight of the runway – what do you do? Circle to land Fly the missed procedure by immediately leveling the wings and flying straight until reaching an altitude at which to turn towards the holding point Descend immediately to regain visual contact with the runway Make a climbing turn toward the landing runway until you are safely established on the missed approach course

Circle to land Descend and maintain the MDA +/- 100 feet until reaching the MAP Descend and maintain the MDA +100/- 0 feet until a descent to a normal landing can be made Select a runway requiring at least a 60° change of direction from the final approach course Select a runway requiring at least a 90° change of direction from the final approach course
