11.2.2 Basics Steps of an Imaging Pattern
Aerial Imaging flight patterns are always flown at 1000' AGL or higher, and
never at speeds below Vx.
How the Mission Pilot maneuvers the aircraft into the proper position for each
shot is very important. The approach to the pattern should be slow and stable,
and the AP must be given enough time to analyze current conditions and set up
for the photo or video imaging run.
Every imaging pattern starts with an “ID Pass” that allows you to verify the
target and note its coordinates. Examine the target, its surroundings, and lighting
conditions. Verify that what you see is what you planned for and that you can
properly frame the target; if not, have the Mission Pilot pick a safe location to loiter
and re-plan how to perform the imaging run (e.g., determine the altitude, angle
and directions you need to get the best photos) and how you wish to frame your
photos.
If you are performing damage assessment and didn’t know the extent or type
of damage to expect when you left on the sortie, the ID Pass will be followed by a
recon survey. The circling flight pattern (below) is a good pattern to use to survey
of damage. Also, you may want to sketch the damage to help you decide what
photos you need and what imaging flight patterns to use. Note: You may need a
combination of flight patterns and/or need to make several runs to capture all the
damage. Be sure to check your fuel status as you may need to refuel and return
to complete your sortie, and update Mission Base on your new sortie time
assumptions.
After the ID Pass (and damage survey, if needed), fly the patterns as shown
below. Remember to fly slowly enough so the photographer can get several
photos from each angle or side.
Photo examples of each type of the following imaging patterns can be found
in the Airborne Photographer Course Slides.
Note
The patterns shown below imply use of the cardinal compass points, which is
the norm. However, crews may adjust the patterns to face whatever
directions work best for the specific circumstances.
