IN-FLIGHT ALERTS 500 AGL Alerts – Alerts when descending through 500 ft. AGL after having been above 1,000 ft. AGL (or when AGL is unknown), the descent rate exceeds 4,000 ft. AGL and the descent rate exceeds 3,000 ft. AGL, the descent rate is between 3000 ft. per minute AGL.

Perhaps just prior to the start of descent could be the optimum time–certainly completed no later than commencement of approach. If you depart MDA on the downwind or base leg, you’re on your own as far as obstacle clearance. Will the vertical speed necessary comply with required descent criteria? What is the runway lighting?

Theyre pretty much the same thing, but heres the difference: DH is measured above the ground (AGL). LPV is the most accurate RNAV approach and can get you as low as 200 feet above the ground (AGL), just like an ILS Category I approach. Instead of a Decision Height (DH), youll use something called a Minimum Descent Altitude (MDA).

Additionally, a pilot should report any of the following events:: When vacating any previously assigned altitude or flight level for a newly assigned altitude or flight level ( AIM 5-3-3 ) When an altitude change will be made if operating on a clearance specifying VFR-on-top. ( AIM 5-3-3 ) When an approach has been missed. (

Even though synthetic vision might help me perform an emergency descent to a valley that might not be cloud filled, that’s pretty sketchy as a risk-mitigation strategy. Also, from when I lived out West, there was the mountaintop clearance guideline—1,000 feet for every 10 knots of wind, with 30 knots meaning no-go.

However, during the descent on an ILS approach, you encounter VMC prior to reaching the initial approach fix. the ILS approach can be credited regardless of actual weather if you are issued an IFR clearance. For any flight above an altitude of 1,200 feet AGL, when the visibility is less than 3 miles. 30 minutes. 45 minutes.

VFR to MVFR…then 2 miles visibility and a ceiling of 1,200 feet agl. Put the aircraft in level flight to give them a moment to consider their next course of action so they are not anxiously doing climbs, descents, and unplanned turns. These flights work best if they are limited to an airport 10 to 15 miles away.
