2) “Minimums” is an aural warning advising you that you have reached the lowest altitude to which you can descend on the approach without seeing the approach lights or the runway, again depending on the type of approach.

Are approach minimums AGL or MSL?

Approach charts (US TPPs) do show AGL below the MSL values. You can always calculate the AGL value from the MSL and field elevation, but having it on the chart gives you a heads-up as to how high above the field you will be if you fly an approach to minimums.

What are ILS minimums?

Visibility minimums are usually one half mile or 2,400 feet runway visual range and may be reduced to 1,800 feet RVR if operative touchdown zone and centerline lights are available. The Cat II ILS has a DH of less than 200 feet, but not less than 100 feet, with visibility minimums of between 1,800 RVR and 1,200 RVR.

What is Ian approach?

Integrated Approach Navigation (IAN) is an approach option designed for airlines that want to use ILS-like pilot procedures, display features, and autopilot control laws for nonprecision (Category I) approaches. The IAN function supports the ILS for glideslope inoperative, localizer only, and backcourse approach types.

What does approaching minimum mean?

Approaching minimums is the decision making altitude or minimum altitude ( Generally 100 feet above the minimum altitude ). Captain callout ‘approaching minimums’ in order to decide that they will land on the runway or they will go around, that depends on the Captain.

What are approach minimums?

Approach minimums are published for different aircraft categories and consist of a minimum altitude (DA, DH, MDA) and required visibility. These minimums are determined by applying the appropriate TERPS criteria.

Can you shoot an approach below minimums?

Pilots flying under the rules of FAR Part 91 are allowed to attempt an instrument approach even when the weather is below minimums. But when skills are rusty, it may be time to be more conservative, as we see in this week’s Probable Cause report.

What are Category 1 minimums?

Lists the minimum requirements for CAT I approaches using a RVR minimum of 1800 feet and a decision altitude (DA) of 200 feet, and CAT I approaches using a RVR minimum as low as 1400 feet and a radar altimeter decision height (DH) as low as 150 feet height above touchdown (HAT) at runways which do not have touchdown …

Is an RNAV approach a precision approach?

While these next two levels of RNAV minimums are not technically precision approaches (they do not meet international standards to be called such), they can be considered “precision-like.” The familiar localizer performance with vertical guidance (LPV) approaches are in almost no material way different from an ILS.

How do you Autoland a 737?

How to Use Autoland on the Default X-Plane 11 737

1. Step 1: Program the FMC With Your Flight Plan.
2. Step 2: Press the INDEX Button.
3. Step 3: Press the Button Next to ARR DATA.
4. Step 4: The Runway’s ILS Frequency Is Under FREQUENCY and Your Course Is Under LOC BRG.
5. Step 5: Enter the ILS Frequency in Both Your NAV Radios.

What does Approaching minimums mean in aviation?

“Approaching Minimums” you are about at your minimum descent altitude (MDA) or decision altitude (DA). “Minimums” means you’ve arrived at that altitude. Pilots use those phrases to alert the pilot flying when they’re getting close to the ground.
