To try to make things totally clear: Suppose that the aircraft is making an approach in knife-edge flight, banked 90 degrees to the right. Suppose that the runway heading is north (it's runway 36). If the aircraft is too low, the glideslope needle in the course deviation indicator will deflect "up" (towards the ceiling), indicating that the aircraft is too ...

LOC and GS work the same way They work on the same principle, but they each have their own radio signal. The localizer is on the frequency tuned in the radio (in range 108.10 MHz to 111.95 MHz), the glide-slope is on an associated frequency from the 329.15 MHz to 335.00 MHz (the mapping is not sequential for some reason). So the localizer needle will still ...

No, the directional part of ILS is located at the ground. (Ground) transmitter creates lobes with specified frequency and modulation to mark the high, low, right and left areas. LOC and GS signals are distinguished by the carrier frequency, deviation from the optimal approach by relative intensity of 90 Hz and 150 Hz modulation in the signal. These signals ...

As long as the aircraft accurately flies down the ILS, it doesn’t matter if it is knife edge, inverted, etc. The indications on the GS and LOC will stay centered. If you deviate from the GS or LOC the deviations will be shown on the respective instruments. The instruments don’t know or don’t care what the aircraft attitude is. The instruments only care about ...

I openend a flight sim (X Plane 10) to check for similarities and differences between the turn and slip indicator and the attitude indicator. If the airplane is horizontal then the airplane symbol on both instruments: turn and slip indicator and attitude indicator display similar data. In a soft turn to the left, the airplane symbol on turn and slip ...

To supplement Transistor's answer: The reason for the light is that tailstrikes are very easy to do on the 400 due to the stretch of the rear fuse with not enough landing gear lengthening to compensate, so they are more limited to the deck angle when landing and taking off than most a/c. This isn't a problem on the other shorter -8s and is mostly unique to ...

The light is a tail-strike indicator. Touched Runway system The Touched Runway system provides a warning light in the flight compartment. It illuminates when the aft fuselage makes hard contact with the runway on take off or landing. The system consists of a frangible1 switch located at the bottom of the aft fuselage, activating the ...

It's called "partial panel" flying and if you ever advance to a commercial license, you will have to demonstrate proficiency at partial panel during training and on the commercial check ride. On my commercial check flight in the late 70s I even had to demonstrate recovery from an unusual attitude (diving spiral) on partial panel under the hood because my ...

The most common killer of inadequately trained pilots who fly into clouds is a spiral dive, caused by the aircraft entering a steep bank without the pilot realizing it or understanding the direction of turn. Eventually the aircraft is destroyed due overspeed or excess G-load. A magnetic compass is generally useless whenever an aircraft is banked and ...

Is it true that a Turn and slip indicator is a valid back-up for the attitude indicator? Partially, but it would need to be used in conjunction with one or more other instruments if the Artificial Horizon is inoperable. Change in the DI and/or compass will indicate a turn. Change in altitude on an altimeter will indicate a climb or descent. Usefulness of ...

In a small aircraft, the turn indicator (and the slightly better turn coordinator) is usually electrically powered, while the attitude indicator is vacuum powered. If the attitude indicator fails, either mechanically or do to vacuum fail, the turn indicator can assist with keeping the wings level in instrument conditions. The slip indicator is merely a ball ...

The "slip" part of the Turn and Slip Indicator (T/S) measures the lateral (transverse) acceleration of the airplane. When the slip indicator is centered, the pilot and passengers will feel gravity directly in-line with the seats; otherwise, they will feel a lateral sway, which doesn't provide the best ride experience, especially if martini spill is involved. ...

The turn and slip instruments are combined for convenience and by convention more than anything else, slip is important whether you are in a turn or not. When you slip it means one wing is more directly pointed into the airflow, which increases lift for that wing in comparison to the other. At a high angle of attack, for instance a climb and close to stall ...

I am stuck calculating the deviation from a coordinated curve indicator, usually the small ball in the turn indicator. The "small ball in the turn indicator" (which pilots use to determine what they need to do with the rudder pedals in order to stay in coordinated flight) is just an inclinometer. It's literally just a heavy ball in a curved tube filled with ...
