Citat:F-22 Raptors, a KC-135 Stratotanker and a C-17 Globemaster III taxi on the runway during a routine training schedule April 21, 2020, at Honolulu International Airport, Hawaii. The active-duty 15th Wing and Air National Guard’s 154th Wing, both assigned to Joint Base Pearl Harbor-Hickam, work together to deliver combat airpower, tanker fuel, humanitarian support and disaster relief across the Indo-Pacific area of responsibility.

The aircraft were part of a demonstration of airpower and consisted of active duty, Guard and Reserve components. (U.S. Air Force photo by Tech. Sgt. Jerilyn Quintanilla)
Citat:An F-22 Raptor from the 325th Fighter Wing flies alongside an F-35 Lightning II from the 33rd Fighter Wing over the Emerald Coast in northwest Florida May 18, 2020. The fifth-generation fighters were part of a nationwide flyover by the Air Force May 15, 2020, saluting healthcare workers, first responders and other essential employees.

-Raptor pilots make sure their hands are off the flight controls and visible when ground crews are working around a running jet because one touch of the stick could cause the 4,000psi hydraulic system to send a control surface into deflection which can decapitate a ground crewman.
-Although the F-22's high altitude capabilities, partially a product of its thrust vectoring capabilities, are known, Gordon notes the aircraft flies at altitudes from 60,000-65,000 feet.
-He describes the pressure-sensitive sidestick control concept, which moves less than a half-inch, very well. The concept was pioneered by the F-16, with the YF-16's sidestick not moving at all before changes were made.
-The flight controls page on the F-22's multi-function-display is really well described here. The level of automation and simple symbology to describe complex issues is remarkable.
-The F-22 knows it is about to take off and automatically reconfigures the plane for departure. It does the same upon touchdown.
-Multiple other automation flight logic modes, in which the flight control system sets to totally different parameters, exist. This is not uncommon on other fly-by-wire aircraft, like airliners, but the F-22's huge flight envelope makes them far more pronounced.
-There is a mode for aerial refueling to give the jet the best fine handling behind the tanker.
-In aerial combat mode, you put pressure on the stick and it locks in a G-rate for a turn and stays there even if you take your hand off the stick.
-When landing, it goes into a pitch command mode, where the pilot simply directs the pitch of the aircraft and it stays there.
-A large number of limiters are used to make sure the jet is not capable of being structurally overloaded and it even automatically unloads individual parts of the aircraft during certain maneuvers by using flight control surfaces non-traditionally.
-When an F-22 drops a weapon, namely a 1,000lb JDAM, fuel automatically sloshes forward to maintain center of gravity. There is no fuel panel on the jet to command this, it is all part of the control logic.

Cudni su oni, neke stvari uvedu ekspresno ali kada neko ima interes da nesto koci...tako i modernizacije na F-22 od kojih neki prave mitove kako je to tesko, gotovo nemoguce izvesti, te daju neke astronomske cifre... I tako tavori i dalje bez nisanske kacige naprimer.
