airport landing indicator

One part of the answer is the so called “instrument landing system (ILS)”. the direction of turns when there is a variation from the 1,989,095 and the more recent device of P. C. Barrett, U.S. Pat. High intensity lamps 35 are further controlled, in the preferred embodiment, as may be seen in FIG. 5, by on-off switching elements, photoelectric cells 80 and 80', which are shielded from the lamps and directionally pointed backwardly and upwardly to be responsive to landing lights from an approaching aircraft. It may be located at the center of a segmented circle and A specific lamp 55 may be lit in accordance with a specific wind velocity as measured by wind velocity monitor 60.

The instrument landing system’s glideslope works in a very similar way.

5. 4 is a perspective view of a runway locator of the present invention; FIG. Shaft 22 may carry at its lower end a contact arm 23 having a pair of contact points 25 and 26 respectively, positioned to move over a pair of circular contact members 24 and 27 which may be concentrally located one within the other in conventional manner. Wind direction determines which of the arrows will be lit for maximum safety in landing.

The perils of landing an aircraft with improper wind direction have long been recognized. Standardization; Training Instrument landing at Nuremberg, Germany, using the ILS! The apparatus may include a wind direction monitor 20; a wind velocity monitor 60; a pair of runway locators 30 and 30'; a pair of specific wind direction indicators 40 and 40'; a pair of wind velocity indicators 50 and 50'; a pair of photoelectric switches 80 and 80' and switches for lighting lamps of the various indicators from an external power source 18, as shown by diagram in FIG. No. Airport Traffic Patterns. Flight Instruments, Chapter 8, Flight Manuals and Other Documents, Chapter 9,

Chapter 17, Aeronautical Decision Making. Flight Management System (FMS) – The Aircraft’s Brain! When conditions at an airport warrant its use, install a landing direction indicator, as located on the drawing, for the purpose of showing pilots in the air and on the ground the direction in which landings and takeoffs are to be made.

The aircraft is on the ideal glidepath, if it flies right in the middle of those two signals.

Extending axially with elongated portion 32 from the foreward most tip of triangular portion 33 of runway locators 30 and 30', wind velocity indicators 50 and 50', respectively, may be located. trailer The board computer now has the task to “find” this zero. xref Basic visual approach slope indicators consist of one set of lights set up some 7 metres (23 ft) from the start of the runway. LX 41 – From Los Angeles to Zurich in the Boeing 777 cockpit. Airports. There is a time in every final approach, when the pilot has to decide wether to continue or abort the landing. The glideslope employs a 90-hertz signal as a “too low” indicator and a 150-hertz signal as a “too high” indicator. It is also preferred that the system not be in constant use because of the obvious heavy electrical drain on the batteries. FIG. Chapter 16, Aeromedical Factors The aircraft is on the ideal course to the runway, if the difference of those two localizer frequencies is equal to zero. 3,537,310. More aviation knowledge will come.

Also, the ILS category indicates until what visibility conditions an approach is allowed. Wind tees and tetrahedrons can

A third frequency can then be tuned in the flight deck. 6 is a schematic of the wind direction monitor and wind velocity monitor of the present invention. when information is provided on the CTAF at a given airport Wind direction determines which of the arrows will be lit for maximum safety in landing. 0000001051 00000 n 5, to provide power from battery 18 to one only of the two runway locators 30 and 30', respectively. 0000002975 00000 n Chapter 4, Aerodynamics of Flight 2.

If the runway is not in sight when the pilots reach the decision height, or some other factor makes a safe landing impossible, the pilots aboirt the landing and initiate a go-around.
