Patts history
PATTS College of Aeronautics was founded in 1969 as the Philippine Air Transport and Training Services,
a joint venture of Filipino and American pioneers in aviation The primar! aim was to esta"lish a
manufacturing and assem"l! plant for training aircrafts The secondar! aim was to start an aeronautical
school to meet the needs of the domestic and international air transportation industr!
The unfavora"le investment climate at the time constrained the founders to drop the first o"jective and
onl! organi#e and operate an aeronautical school, intended to provide professional and technical training
to its clients The school started with $ne%&ear Airframe 'echanic, Two(&ear Airframe 'echanic, $ne
&ear Power Plant 'echanic and Two(&ear Power Plant 'echanic courses )n its second !ear of operation
the Communication Technician course *Avionics+ and the Four(&ear Aeronautical ngineering course
were added
-nder the stewardship of its .oard of /irectors, the school rose to higher levels of credit and educational
standards )ts .S Aeronautical ngineering graduates regularl! topped the P0Cs 2icensure .oard
3amination for Aeronautical ngineers from its inception in 1945 )n 1949, the school "ecame an
accredited college PATS School grew into a larger educational institution nown as PATTS College of
Aeronautics, adapting the slogan 7Fl! high, !our future is in the sies8
)n ::;, the school<s greatest transformation coincided with PATTS< 56th anniversar! PATTS was
relocated from its old site at /omestic Airport 0oad, Pasa! Cit! to its new home at 2om"os Avenue, San
)sidro, Para=a>ue Cit! The new four(stor! "uilding, e>uipped with modern facilities, sits on a spacious
campus ducational successes encouraged the .oard of /irectors to "e more forward(thining in their
management of the school Following the 56th Anniversar! theme, 7To )nfinit! and .e!ond8, management
announced a new diversification polic! PATTS would offer non(aviation related programs responsive to
industr! needs, starting with .S ?otel and 0estaurant 'anagement as of the ::;%::6 school !earFeasi"ilit! studies are "eing conducted to determine what other curricular offerings are via"le @raduate

et Fuel ?istor!
Jet fuel is a specific type of kerosene fuel for aircraft with gas-turbine engines. There aredifferent grades of fuel; Jet A and Jet A-1 are the most popular. Jet fuel is a mix of manydifferent hydrocarbons in varying proportions. t is also designed with a low flash point !11" degrees in military #ets$ to improve ignition.
The First Jet Engines
• The first jet engines were used in World War II by the Germans. Hans von Ohain
built a jet engine that flew a plane on Aug. 2! "#$#. The engine was powered by gasoline.%nglishman &ran' Whittle developed his own jet engine! but it wasn(t used to fly a plane
until )ay "*! "#*". +e,ause of a gasoline shortage ,aused by the war! Whittle(s engine used
'erosene! whi,h remains the base of modern jet fuels.

Improvements
• Though the earliest jet engines ,ould use most types of fuel! as the engines improved
so did their need for -uality fuel. )ore effi,ient engines re-uired fuels that ,ould provide
the power the engines needed. Two of the basi, improvements were higher flash points
temperature at whi,h the fuel ignites/ and lower free0e points. Higher flash points redu,ed
the ris' of fire. As jets began to ,limb to higher altitudes! the outside temperature of the
plane dropped so lower free0e points minimi0ed the ris' of the fuel free0ing.
JP!
• The first jet fuel was developed at the end of World War II. The spe,ifi,ations were
published in "#** and it was ,alled 13" or 1et ropellant ". While the fuel wor'ed! the
military began loo'ing for ways to improve it and thereby! improve the performan,e of its
jets. Other variations in,luded 132 it proved too flammable/ and 13$! whi,h had vapor
lo,' and fuel3loss problems.
JP"
•
13* or 1et ropellant * was a 'erosene3gasoline mi4ture that wor'ed well and wasused by the 5.6. Air &or,e from "#7" until the mid3"##8s. It was similar to the 1et + fuel
used by privately owned planes.
JP#
• 137 ,ame about in "#72. It had a higher flash point! whi,h made a good fuel for use
aboard air,raft ,arriers where fires were always a danger. It ,ontinues to be used by most
navies today. This fuel is also ,alled &3** or av,at.
JP$
• The Air &or,e swit,hed from 13* to 139 in the "##8s! though it was developed in
"#9. It has a higher flashpoint than 13* and is less ,ar,inogeni,. Its formulation is similar
to 1et A3" fuel! whi,h is used by ,ommer,ial air,raft.
