PATHFINDER

“I didn't start out to chart the skies; it's just no one had done it before.”

Elrey B. Jeppesen

Born in Lake Arthur, LA on January 28, 1907, Elrey Jeppesen landed once at Tucson on August 15, 1929 flying Alexander Eaglerock NC6314.  He had only been a pilot for two years or so.  His airplane was an A-3 model with OX-5 engine.  He was based at Dallas, TX and his itinerary that brought him to Tucson was from Portland, OR to Santa Monica, CA.  He left nothing in the Register that suggested the purpose for his solo trip.

Not long after his visit to Tucson, “Jepp”, as he was called, began a business that has had lasting and fundamental impact on the aviation community to this day.  His legacy is in aerial navigation and the charting that pilots use to fly from place to place.

Jeppesen learned to fly in 1927 after taking a ride with a barnstormer in 1921 at Portland, OR.  Just before learning to fly, at age 18, he joined Tex Rankin’s flying circus, first as a ticket seller, than as a prop twister and wing walker.  After he learned to fly, with his $500 savings, he bought his first airplane, as surplus OX-5 Jenny.  He organized and operated his own flying circus in the Oregon-Washington area.

During his learning period he also took courses in photography, engineering and mathematics.  He became adept at taking pictures from his airplane.  In 1928, when he was 21, he worked for the Fairchild Aerial Surveys Company as manager of their foreign photographic mapping division, based in Mexico City. 

Jeppesen's "Little Black Book"

For two years he flew thousands of miles making the first photo mappings of the Mexican coast from Brownsville, TX to beyond the Yucatan Peninsula.  Interestingly, at least three of Fairchild Aerial Surveys’ airplanes landed at Tucson.  For example, see NR8016, NC9174, and NC8006.

In 1930 he joined the Boeing Air Transport Company, forerunner of United Airlines, as an airmail pilot with the rank of captain.  He flew routes like Salt Lake City to Reno, Cheyenne to Salt Lake and Cheyenne to Omaha.  He experienced the poor navigational system that caused many pilots to become lost (four of the 20 Boeing pilots were killed in airplane accidents during the winter of 1930).

He purchased a notebook (left) in Cheyenne, carried it with him on every flight, and jotted down particulars of airports and terrain profiles.  Armed with his notebook, Jepp had an enviable record of completed flights.  He recorded field lengths, slope, drainage patterns, obstacles, airfield layouts, telephone numbers of farmers who could provide weather reports, and beacon and light information.

He had no idea of commercializing his concept; he was merely collecting information for his own personal use as a pilot.  He went so far as to climb hills with an altimeter to obtain accurate data about safe minimum altitudes for an airplane crossing the area. 

He measured the heights of smokestacks and water towers in the vicinity of airports to establish safe circling altitudes for himself.  When radio ranges were installed by the government in 1931-32, he flew all legs of each installation and transcribed into his notebook the safe letdown procedures for airports from Omaha and Cheyenne to Salt Lake City and Oakland.

Jeppesen's "Little Black Book"

His “little black book” became popular among early pilots.  So much so that in 1934 he borrowed $450 and set up business in his basement in Cheyenne and published the first of his Airway Manuals: fifty mimeographed copies which sold out immediately for $10 each (don't forget, this was in the middle of the Great Depression).

Over the next 20 years he built his charting business, and worked as a transport pilot for United Airlines.  He had a busy career balancing his business and United responsibilities.  His business blossomed with WWII, as he was the only person in the country with such a huge compilation of nationwide flying information which was vital to national defense.  The Army used his manuals, and the Navy signed a contract with his firm.

In 1954 he took early retirement from United to devote more time to his expanding firm.  By the end of the decade he employed 200 people in a new building he had constructed in Denver, CO.  In 1961 he sold the firm to the Time Mirror Publishing Company, but still remained as President and then Chairman of the Board. 

Jeppesen's "Little Black Book"

On November 16, 1971 Jeppesen received the FAA’s distinguished Service Award for outstanding contributions to the progress and safety of aviation.  His files then contained data on millions of miles of charted airways, diagrams of 8,000 airfields, national weather interpretation and the latest information on approach patterns and takeoff and landing procedures, including communication and navigation frequencies and obstacle avoidance information.  The award citation hailed him as, “…America’s pioneer charter of airports and foremost mapper of skyways.”

Jeppesen’s flying career spanned 50 years, three million miles and 20,000 hours of flight time.  Jeppesen Sanderson, Inc. (a subsidiary of Boeing) survives today as the company he founded, still compiling and publishing aerial navigational aids for aviators.  Nearly all U.S. commercial airlines and many foreign airlines, as well as a large percentage of instrument-qualified private, business and executive pilots, use Jeppesen charts for enroute planning and guidance, as well as for terminal approach procedures.

He leveraged his 10-cent notebook into a $121-million company (as of 2005), and became a self-made millionaire in the process. Pilot Jeppesen flew West on November 26, 1996. We can be assured he did not get lost.
