Bullseye

by [OFS] kaltokri / Rolf - Sunday, 27 December 2020, 9:54 PM
 

Das Bullseye ist ein vordefinierter Punkt, der als Referenz für Funkrufe zur Angabe einer Position verwendet wird. Wenn beispielsweise jemand sagt, dass er einen Radarkontakt bei "Bullseye 050 at 30 miles" hat, ist der Radarkontakt 30 Meilen vom Bullseye-Punkt bei einem Kurs von 050 (etwa Nordosten) entfernt.

Bully wird verwendet, wenn der Funkverkehr vom Feind abgehört werden kann. Da der Bullseye-Punkt vor dem Flug vereinbart und nicht über Funk angegeben wird, kann der Feind bei Verwendung der Bullseye-Terminologie nicht feststellen, auf welchen Punkt sie sich beziehen. Darüber hinaus trägt die Verwendung von Bullseye-Koordinaten zur Verbesserung des Situationsbewusstseins bei, da es sich um einen absoluten Bezugsrahmen handelt. Wenn AWACS einem anderen Flugzeug mitteilt, dass es bei "3 Uhr, 25 Meilen" feindliche Jäger hat, hat er keine Ahnung, wo sie sich befinden. Wenn man jedoch sagt, dass sich die Jäger bei "Bullseye 120 bei 100 Meilen" befinden, weiß man genau, wo sie sich befinden.

Artificial Horizon

by [OFS] Gosling (en) / Jerry - Saturday, 19 March 2022, 2:47 PM
 

 

The main instrument of understanding the aircraft‘s attitude with respect to earth’s surface.  

It is a gyro (or graphical representation) driven by either:

  • A mechanism to maintain its orientation relative to the earth’s surface through rigidity and precession.  
  • A ring laser and accelerometer driven Attitude and Heading Reference System (AHRS)

It is normally mounted centrally on an aircraft main instrument panel.  It can be implemented as graphics within a “glass Cockpit”.

1 in 60 Rule

by [OFS] Gosling (en) / Jerry - Sunday, 27 March 2022, 11:32 AM
 

This is a method of assessing distance between diverging (or converging) tracks.  

For every degree difference between two tracks there is a 1 nautical mile separation after 60 nautical miles of travel.  

E.g. If a track is flown 5˚ Off heading, after 12 nautical miles there will be 1 nm separation.  

This only works up to about 15˚ of track separation.  

 

VOR

ASE

by [OFS] Rufuz - Saturday, 30 April 2022, 6:50 PM
 

(AH-64D Apache) Aircraft Survivability Equipment (Page)

BUCS

by [OFS] Rufuz - Saturday, 30 April 2022, 6:50 PM
 

(AH-64D Apache) Back-Up Control System

Normally, the pilot and CPG flight controls are mechanically linked. The mechanical linkages are protected by shear pins and mis-track sensors to prevent a control jam or severance from affecting both sets of flight controls. If the flight controls are decoupled by the shear pin, or a mis-track is otherwise sensed, the Back-Up Control System is automatically activated. The BUCS is a single-channel, four-axis, non-redundant electric fly-by-wire (FBW) system. The FBW system is designed to replicate the feel of the hydromechanical controls but does not replicate SCAS functionality. BUCS can only be active for the pilot or the CPG station. Either the pilot or the CPG can transfer BUCS control to their station if necessary, depending on the nature and location of the jam or severance within the flight controls.

The IPAS provides pressurized air to aircraft pneumatic systems. Bleed air is drawn from two ports: a high-pressure port is exclusively used to pressurize the hydraulic systems, and a low-pressure port is used by all other consumers. Low-pressure air is used by the engine air turbine starters, fuel boost and transfer pumps, anti-ice system, ice detection probe, nitrogen inerting unit, vapor cycle cooling system, and environmental control system. IPAS bleed air can be provided by one or both engines, the APU, or an external source such as an AGPU.
