If, for some reason such as economy, we are not going to develop aircraft nuclear propulsion with a sense of national urgency, then we should turn our effort to developing jet engines with a thrust-to-weight ratio of 12 or 15 to one.

" If the aircraft is not being hijacked, the pilot should not squawk 7500 and should inform the controller accordingly.

If the air on one side of the diaphragm is at the static pressure, and the other at the stagnation pressure, then the deflection of the diaphragm is proportional to the dynamic pressure, which can then be used to determine the indicated airspeed of the aircraft.

If the weather is below VMC, pilots are required to use instrument flight rules, and operation of the aircraft will primarily be through referencing the instruments rather than visual reference.

If an aircraft is flying over a congested area ( town, settlement, etc.

If the rocket or aircraft is moving at about a constant speed, then distance divided by time is just speed, so power is thrust times speed:

If the aircraft carrying the Hiroshima and Nagasaki bombs had been within the intense nuclear radiation zone when the bombs exploded over those cities, then they would have suffered effects from the charge separation ( radial ) EMP.

If its leading edge is raked back enough, it will escape the shock wave formed at the nose of the aircraft as transonic speeds are reached, reducing drag considerably, and the center of lift moves less than on conventionally configured aircraft, reducing trim drag.

The next citations are not found until 1955, when the May – June issue of Aviation Mechanics Bulletin included the line " Murphy's Law: If an aircraft part can be installed incorrectly, someone will install it that way ," and Lloyd Mallan's book, Men, Rockets and Space Rats, referred to: " Colonel Stapp's favorite takeoff on sober scientific laws — Murphy's Law, Stapp calls it —' Everything that can possibly go wrong will go wrong '.

If they are selected to serve as a pilot ( aircraft ), they will serve 8 – 11 years minimum from their date of winging, and if they are selected to serve as a naval flight officer they will serve 6 – 8 years.

If the APU or its electrical generator is not available, the aircraft cannot be released for ETOPS flight and is forced to take a longer non-ETOPS route.

If they are not successful, the decision to shoot down the aircraft before it reaches United States airspace is made, trading the lives of the approximately 400 innocent passengers to save the lives of hundreds of thousands of people on the ground.

If the leading edge of the aileron is sharp or bluntly rounded, that adds significant drag to that wing and help the aircraft to yaw ( turn ) in the desired direction, but adds some unpleasant or potentially dangerous aerodynamic vibration ( flutter ).

If attached close to the wing root, it makes the stall gentle and progressive ; if attached near the wing tip, it encourages the aircraft to drop a wing when stalling.

If you change this example to then the analogy would be flying in space to reach any position in 3D space ( ignoring the orientation of the aircraft ).

If that pulse is on the same frequency as the sent signal, it will cause a second blip to appear on the radar display, forming the basis of early IFF systems-those blips that are doubled up have the proper transponder, and are thus friendly aircraft.

If the signal from two stations arrived at the same time, the aircraft must be an equal distance from both transmitters, allowing the navigator to determine a line of position on his chart of all the positions at that distance from both stations.

* If the aircraft is a glider a maximum never exceed speed ( Vne ) of CAS

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.
