A remote pilot receives a LAANC authorization showing '100 feet' for a Class D grid near a regional airport. Their planned altitude for a real estate shoot is 150 feet AGL. What does this mean operationally?
Why →LAANC grid values represent the maximum altitude automatically authorized in that grid cell. A 100-foot authorization means FAA pre-approval up to 100 feet AGL only. Flying above 100 feet without additional authorization violates the authorization and 14 CFR § 107.41. Higher altitude requests must go through FAA DroneZone for manual ATC review.
The trap →LAANC grid values are ceilings, not floors. They are not advisory. Operating above the authorized altitude without additional approval is an airspace violation. Grid values reflect FAA analysis of local air traffic patterns.
Field note →If LAANC shows 0 feet in a grid, auto-authorization is not available at any altitude, but you can still request manual authorization through FAA DroneZone. DroneZone approvals may take several days, so plan commercial shoots near airports well in advance.
