Learjet Cruise SpeedSpeed of Learjet Cruise
In order to use the kneeboard during flight, either hit SHIFT+F10 or click on Kneeboard in the Airplane Setup screen. Please note: All velocities indicated in the flight notes are indicated flight velocities. When using these velocities as a benchmark, make sure that you choose "Show Displayed Airspeed" in the Realism Settings dialogue window. The velocities shown in the Specification chart are displayed as real flight velocities.
As standard, this airplane has full propellant and full cargo capacity. You will not get the same total power as with a light truck due to weather condition, height and other considerations. Length needed for take-off and landings depends on a number of variables such as airplane mass, height, headwind, flap use and environmental temperatures.
In order to roll the Learjet, use just enough current to get it to roll and then return the throttle to neutral. Neutral kick works well to keep you in motion. Go through the check list before starting and adjust the dampers to 8 or 20 as required (press down or pull the dampers lever).
When the plane is pointing to the center line of the take-off and landing runways, move the choke (press F3 or pull the levers) to about 40 per cent S1. Thus, the thrusters are able to coil to a point where there is an even increase in take-off thrust at both thrusters. It is not so important to set the precise height of the basic adjustment as to set the symmetric shear.
Once the power plants are stabilised, bring the throttle arms to take-off push "generally 93 to 96 per cent nitrogen (less at high outside temperature). Steering is retained by using the rowing controls (turn the joy stick, use the rowing controls, or push 0[left] or ENTER[right] on the decimal keyboard).
The airspeed displayed at V1, approx. 136 nodes (KIAS), is the speed of decisions. If this speed is exceeded, it may not be possible to stop the aeroplane on the take-off strip if the take-off is refused (RTO). For Vr, about 143 KIAS, gently retract the flash drive (use the joy switch or yokes or press the down arrow) to lift the lug 10 degree above the horizontal.
Maintain this tilt position and ensure that you do not overwind. The plane has achieved its take-off security speed at 2 V, approx. 146 KIAS. It is the minimal airspeed in the event of an intermittent failure of an airplane powerplant. Keep this speed until you get a favorable climbing speed. Once the airplane has a lift ratio (both speed and elevation increase), pull in the undercarriage ( push down key or pull the lever).
Aeroplane quickly accelerates to damper intake speed. Insert the dampers (press down key 6 or remove the lever). Once the transmission and hatches are retracted, you only need to decrease your output if you settle below 10,000 ft (3,048 m) and stay below FAA speed limitations. For example, to stay at 200 KIAS at 610 metres altitude, decrease the output to 53 to 55 per cent S1.
An output adjustment of 60 to 63 per cent gives you 250 KIAS at the same height. When continuing your ascent above 10,000 ft, keep the current on as long as it stays below the "maximum permanent temperature" of the ITT. You' re supposed to be 1,800 to 2,000 ft per minute. Come on.
Learjet riders often let their engine run at full speed. Raise the tilt setting to keep 250 knot until you reach 0.7 Mach. Then hold 0.7 Mach for the remainder of the rise. You have to raise the force while climbing to get the just described outline.
Cruising altitudes are usually influenced by wind, wheather and other conditions. The optimal height is the height that provides the best mileage for a given setup and total vehicle mass. This Learjet is conceived for high-altitude flight. They can cross up to an elevation of FL450 (the aircraft is 51,000 ft certified), but the only advantages for the combustion of the gas it needs to get there would be overcoming a meteorological system or using particularly favourable winches.
If you are approaching your cruise level, start levelling about 15 metres below your destination area. You will find that it is much simpler to use the Learjet during cruise if you use the auto-pilot. Auto pilot can maintain the elevation, speed, direction or navigation course you specify. Regular cruise speed is 0. 77 Mach.
When you display the indicated air speed on the speedometer, the pin will deposit at about 280 KIAS. With FL370 you can expect a speed above bottom of about 429 kn (794 km/h or 494 mph). The Learjet 45 offers its best speed in travel at 10,058 metres (33,000 feet), where it rides at 444 KIAS with a consumption of around 1,715 lbs of petrol per hour. 444 KIAS.
Good relegation profiles include knowledge of when to take off from cruising altitudes and how to plan your flight. Normally the relegation is done with idling and proper setup (no speed brakes). One good way to determine when to begin the relegation is to use the 3:1 ratio (three mile per thousand ft in altitude). Take your height in ft, let the last three zeroes fall and multiplied by 3. For example, to relegate from an elevation of 35,000 ft (10,668 meters) to ocean level: 35,000 minus the last three zeroes is 35.
That means you should start your descent 105 sea-mile from your target, keeping a speed of 250 KIAS and a sink speed of 1,500 to 2,000 ft per min, with the no-load push at 53 per cent n. p. 1. For lowering, deactivate the auto-pilot when it is on while driving (or use the autopilot's holding functions and let it go for you).
Reducing the idling speed and lowering the nozzle slightly. Please keep in mind not to go over the prescribed maximum speed of 250 KIAS below 3,048 metres. Eventually you will need to adapt the performance to keep your speed and sink speed constant. Resume this airfoil until the beginning of the landing stage of the aircraft.
Schedule an early approximation correction, regardless of whether you are approaching an instrumentset or not. Good speed targets when entering the headwind for the VFR or the first fixed landing for the IFR are 200 KIAS. When you begin the approximation, but before you turn to the take-off and landing runways, return energy and maintain height to slow down speed.
If you are nearing the standard lowering point on a visible approximation, or a point under the glide slope nearing the end glide fixed on an ILS attachment, lower the undercarriage. Gently boost performance to sustain 140 kn, your cruising speed. These configurations should keep the airspeed at 140 kn with a good downward slope towards the airstrip.
Maintain 140 kn in your glide to the stop. Move the throttle arms about 50 ft above the take-off and landing runways and behind the run-off and landing thresholds to neutral. Maintain the posture you used during the glide phase. As you land, unfold the spoiler (press SLASH [ / ]) and insert the backstroke ( push F1 or pull the throttle in the opposite position) and brake.
Ensure that you come out of the counter push (press the F1 or pull the throttle) and lower the spoiler if the airspeed falls below 60 knots. Check that the airspeed is below 60 kts.
