If we could use all the small airfields we have in this country, we could disperse our strategic aircraft by a factor of 10 or more.

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 a jet aircraft is at full throttle but is tied to a very strong tree with a very strong chain, then the jet engine produces no propulsive power.

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 an airliner is defined as a plane intended for carrying multiple passengers in commercial service, the Russian Sikorsky Ilya Muromets was the first official passenger aircraft.

If seen, parachutist and light aircraft avoid dust devils.

If a loss of radio communications were to be encountered during VFR conditions, or if VFR conditions are encountered after loss of communication with the ground and other aircraft, the pilot of the aircraft shall continue the flight under VFR and land as soon as practicable.

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 operating system detects that a program has tried to alter memory that does not belong to it, the program is terminated.

If the spacecraft detects an anomaly, it changes the carrier between four tones, based on urgency.

: If the watch-dog detects an intruder, the dog will bark.

If an internal monitor detects radioactivity, the flask is shattered, releasing the poison that kills the cat.

If a receiver is connected to the system in the middle of a frame transmission, it ignores the data until it detects a new frame synchronization sequence.

If a more general measurement is made that detects the system in a state then the system makes a " jump " or quantum leap from the original state to the final state with probability of.

If the variables are independent, Pearson's correlation coefficient is 0, but the converse is not true because the correlation coefficient detects only linear dependencies between two variables.

If the sentinel detects a predator, it gives a loud alarm to warn the troop and indicate whether the threat comes from the air or the ground: if from the air, the meerkats rush to the nearest hole ; if from the ground, the troop flees.

* If Gyakuten Kenji 2 detects a pirated or downloaded copy of the game, it will convert the entire game's text into the game's symbol based foreign language, Borginian, which cannot be translated in any way.

If it detects any traffic prior to its own greeting ( in violation of RFC 2821 ) it closes the connection.

If the router detects a network unreachable, the timer is started.

If the Built-In Test equipment detects a fault the missile will be returned to MBDA for repair.

If the saw detects a change in this current ( as would occur if a hand or other body part came into contact with the blade ) an automatic braking system is activated, forcing an aluminum brake block into the blade.

If it detects that the program has tried to hook into DOS, it will jump back into the 16-bit code to let the hook run.

If the processor detects a protection violation, it stops executing the code and sends a GPF interrupt.

If a home fecal occult blood test detects blood in the stool it is recommended to see a health professional to arrange further testing.

If the disk drive detects multiple read errors on a sector it may make a copy of the failing sector on another part of the disk-remapping the failed sector of the disk to a spare sector without the involvement of the operating system ( though this may be delayed until the next write to the sector ).

If the left wheels are on asphalt and the right wheels are on ice, during an emergency stop, ABS detects the right wheels about to lock and reduces braking force on the right wheels, helping to avoid lock-up and loss of vehicle control.

If the yaw sensor detects more / less yaw than the steering wheel angle should create, the car is understeering or oversteering and ESC activates one of the front or rear brakes to rotate the car back onto its intended course.

If it detects something, it will alert the operator.

If this step detects a negative cycle, the algorithm is terminated.

If a system failure causes data corruption then when the MKDE is restarted it detects all the files that had a failed system transaction and tried to recover them.

If the link layer receiver detects a CRC error, the receiver notifies the transmitter via a flit on the return link of the pair and the transmitter resends the flit.

If it detects an answering machine, the dialer hangs up.
