AERIAL IMAGERYPart I Lt Col James Babbitt, CAP A5(XP)/Plans and Programs Maryland Wing With recognition and appreciation to Texas Wing from whose Mission Videographer Training Program this presentation was derived
AGENDA • What we will cover: • Flight maneuvers • Crew mechanics • Conducting an imagery mission
AGENDA • What we won’t cover: • Camera operation • Video imagery • Satellite Digital Imaging System (SDIS) transmission • ARCHER system -- Controlled by National HQs
FLIGHT PROFILES • Point Targets • 4-Square Pattern • The standard • Easiest • Most stable • Bird’s Eye Pattern • Provides overview of a target • When detail and geographical referencing is required • 45° Angle Pattern -- Employed upon customer request • Linear Targets • Area Targets • Assessment survey • Combination of multiple patterns
FLIGHT PROFILES • All crewmembers must be familiar with how any particular imaging pattern will be approached and flown • Planning is essential • Navigation data determined prior to pre-flight (e.g., lat/long of all entry and turning points) • Employ the GPS and/or VORs
FLIGHT PROFILES • MP’s responsibility -- Maneuver the aircraft into the agreed upon profile • Stable flight • Altitude -- 1000’ AGL • Provide the imager sufficient time to set up the photo • Each pattern starts with an “ID Pass” • Verifies the target • Establishes its coordinates. • Permits the imager to examine the target and determine best framing
4 SQUARE PATTERN ID PASS .5 – 1.0 NM 1,000’ AGL EXIT

45° TO TARGET PATTERN VARIBLE AGL NM AGL 45O AGL ID PASS
AREA TARGETS • Commonly requires a combination of flight patterns and/or need to make several passes to capture all targets • Parallel line search permits the crew to conduct an assessment over a broad area – GPS coordinates captured for individual follow up

CONDUCTING A SORTIE • The key to a successful imaging mission is preparation, planning, patience and practice! • Majority of missions are “fly back” missions, where we take photos, return to base, and then transmit the images to our customer • Missions where we take photos and transmit them from the aircraft (Satellite Digital Imaging System) require specialized equipment and training • The way we plan and take photos is the same whether it is a fly back or SDIS mission
CREW COMPOSITION AND RESPONSIBILITIES • The Photographer is normally the Mission Commander, while the MP retains responsibility for the safety of the flight as Aircraft Commander • Determine Photo Log requirements and brief the Log Keeper on data needed and how the MP and Photographer will communicate this information
BRIEFING • Ensure your understanding of the target(s) and the customer’s requirements • What and where is the target? • Name and description of the target • Define the target location by at least two forms of navigational information such as Lat/Long and VOR radial/DME
BRIEFING • What are the customer’s requirements? • Is the target a single feature or facility, such as a building? If so, do they want as close a picture as possible (e.g., completely filling the frame)? • Does the customer want to see the target and its environs to allow a larger perspective? • Does the customer want to see roads and/or power lines leading to or from the target? If so, how far out from the target?
BRIEFING • How should the target and surrounding features be imaged? • Does the customer want to see the extent of flooding below a dam or levee, or the entire trail of debris from a tornado? • Does the customer want wide shots followed by close-ups? • Does the customer want the shots taken from a certain altitude (AGL) or from a specific angle to the target? Or is it OK to change altitudes and/or zoom as necessary to get the best shot?
BRIEFING • What information do they want to accompany the images? Accompanying information may include: • Altitude (MSL or AGL, or both) • Latitude and Longitude • Time (local or Zulu) • Distance from target (nautical or statue miles) • Direction to target (e.g., looking South) • Angle to target (e.g., 45°)
BRIEFING • What quality do they want (e.g., highest, medium or low)? • This also helps you determine how large (or how many) media cards you will need for the sortie
INVENTORY EQUIPMENT • Camera batteries charged (including spares) • Memory cards with sufficient capacit • Photo Log, Recon Sketch Sheet, and Image Pattern Planning sheets (along with a good clipboard) • Seat cushion
PREPARE EQUIPMENT • Turn on the camera and check status • Full battery charge • Sufficient space on the media card • Set camera time to your time hack • Set the exposure mode • Check or set image type, resolution and quality -- The best choice for the majority of CAP imaging missions is JPG with the highest resolution with the best quality. • Turn on the laptop and check for full battery charge and proper settings
PREPARE the AIRCRAFT • Clean the aircraft windows • Enter waypoints into the GPS before takeoff • Set up and test the audio Panel and Intercom • Check the imaging equipment -- Note: A shot of the aircraft ‘N’ number provides a good “starting image” for the sortie, particularly if there are images on your media card or tape from a previous sortie • Arrange equipment for easy access, ensure lightweight objects are not lying loose where they can be blown about the cabin when you open a window
TRANSITING TO THE TARGET AREA • Once you’re out of congested airspace, relax the sterile cockpit rules while maintaining situational awareness • Double-check navigational settings to be used in the search area • Review search area terrain and obstacles • Update in-flight weather • Execute methods to reduce fatigue or combat high altitude effects during the sortie
APPROACH • Turn on exterior lights to maximize visibility to others can -- Note: You may need to turn off the strobe lights so they will not affect the photos, particularly in low-overcast conditions • Review sortie objectives and crew communications, and set the audio panel and intercom for imaging pattern communications. • Double-check radio and navigational settings and check navigational equipment against each other (detect abnormalities or failures).
APPROACH • Stabilize at ‘Target ID Pass’ heading, altitude and airspeed (not < Vx) at least two miles out. • This allows time for everyone to get set for the photo or video run, and gives everyone the opportunity to see what visibility and turbulence conditions will be encountered over the target area
