The new engines lack thrust reversers; they are not needed because their idle thrust is only 40 lbf, as opposed to 400 lbf on the old engines. | The new engines lack thrust reversers; they are not needed because their idle thrust is only 40 lbf, as opposed to 400 lbf on the old engines. | ||

At low altitude, this aeroplane is light and slow enough for sightseeing in the canyons. At high altitude, it is fast enough for medium-haul, multiple-hour flights and GPS navigation. You can fly VFR or IFR, with or without GPS. | At low altitude, this aeroplane is light and slow enough for sightseeing in the canyons.

== Manual landing procedure == | |||
As with most aeroplanes, you maintain a constant pitch and speed using the yoke and control descent rate (vertical speed) using throttle. The Citation II has an Angle of Attack indicator, left of the airspeed indicator, to help with this. This instrument uses an arbitrary unit going from 0.0 to 1.0 (these are not degrees; 1.0 corresponds to 14 degrees). The needle should be in the green zone for climb and cruise and in the white zone for landing. The red zone indicates a stall. | |||
* Reduce speed to 170 knots indicated. | |||
* Deploy flaps 3 steps (i.e. approach configuration). | |||
* When the runway is in sight, increase throttle to n2=58% then deploy flaps 5 more steps (full flaps). | |||
* Watch the angle of attack indicator. | |||
* Push or pull the yoke to keep the angle of attack in the white zone. Do not let the needle into the red zone, or you will stall. | |||
* At this point your throttle should be approximately n2=58%, AoA=0.6, airspeed=120 knots, descent rate=-500 feet/min. | |||
* Extend gear. | |||
* Look at the [[Precision_Approach_Path_Indicator|Precision Approach Path Indicator]] lights next to the runway. | |||
* Reduce throttle a litte bit to descend faster; increase throttle to descend slower. Avoid rapid or large changes to throttle. | |||
* The ideal vertical speed on touchdown is -500 feet per minute. | |||
* When the rear wheels touch the ground, cut throttle and deploy speedbrakes (press {{key press|k}}). | |||
* Wait for the nose wheel to touch the ground by itself. | |||
* On the Citation II, deploy thrust reversers (press {{key press|Del}}) then open full throttle. The Sierra Super II lacks thrust reversers. | |||
* Apply brakes as necessary. | |||

==== will be released with 2017.2 ==== | |||
* Tutorials have been added. | |||
* A new menu item is in place. The '''Citation II config''' dialog is available under menu -> Citation II -> Citation II config. It contains options for saving through sessions, some display options and several shortcuts for easy access to tutorials, help and more. | |||
* New support for [[State_Overlay_System|state overlays]]. Activate state overlay by adding <code>--state=$state</code> to your command-line. | |||
$state can be: | |||
* '''parking''' ( cold and dark, all systems off) (same as without <code>--state=$state</code> ) | |||
* '''taxi''' ( engines and all systems running - ready to taxi ) | |||
* '''take-off''' ( flaps and AP set - just throttle up and go ) | |||
* '''cruise''' ( flying at FL360 on AP ) | |||
* '''approach''' ( !experimental! use with: | |||
''--glideslope=degrees'' ( usually 3 ) '''or''' | |||
''--altitude=ft-above-msl'' ( alt above sea level ) '''or''' | |||
''--offset-distance=nm'' ( 10 seems like a good start ) | |||
Never use all 3 options at once! Only 2 of them. Triangle calculation - remember? | |||
''--in-air'' ( well, just do it... ) | |||
if you want, you can add options like this: | |||
''--nav1=rad:freq'' ( Going into [https://skyvector.com/airport/LPAZ/Santa-Maria-Airport LPAZ] 18 enter --nav1=179:110.300 meaning NAV1 is set to 110.300 MHz with a radial of 179°, which is the G/S of LPAZ-18 ) | |||
