AGL Ceiling Clearance 
Pilot Institute
JUNE 27, 2025
Know what special scenarios still require a waiver, such as flying BVLOS operations, flights above people, or flights that exceed the standard 400 feet AGL. Aircraft must operate under ATC clearance. Shelf area: 10 NM radius, from 1,200 ft AGL to 4,000 ft AGL. Ceiling is labeled in brackets within the airspace.

Our NIFA team of pilots would travel to other colleges and compete in sanctioned competition involving precise navigation, pre-flight inspections, accuracy landings, and simulated bomb drops into a barrel from 100 AGL feet using bean bags as bombs. I filed my IFR flight plan, received a clearance and took off into the gray winter sky.

AGL Above Ground Level AGL is simply a way to tell the basis from which any given height or altitude is measured. Simply put, 400 feet AGL means that the 400 feet is measured from the underlying ground surface above the specific airspace. This is as opposed to other altitude measurements, such as AMSL or above mean sea level.

What is the minimum ceiling and visibility for takeoff, landing, or entering the traffic pattern of an airport in Class E airspace under visual flight rules? A ceiling of 1,000 feet and have visibility of at least 3 statute miles. To operate in Class D airspace, you must: Be in contact with ATC and have a clearance to enter.

The route is simple, GPS direct, but…there’s my personal 1,000-foot en route ceiling requirement, and those silly Smoky Mountains. 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. It was now time to plan the trip.

While Class E airspace is considered controlled airspace, you do not need an ATC clearance to fly in it. Since Class “E” airspace is basically “everywhere”, most of the focus is placed on identifying the ceiling and floor of the airspace. But how can you know the difference?

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. ( Each is defined by varying ceilings and visibility.
