Ever heard of the “bird” or Velocity vector in the Heads-Up Display?

Did you know that in the HUD (Heads Up Display) of most aircraft in X-Plane there is a tool that helps you to visually align your aircraft to the the runway touchdown point when you have a crosswind messing you around.

The Velocity Vector (often referred to as the Flight Path Vector or FPV, and represented on the HUD as a small circle with tiny wings, sometimes called the “bird”) is one of the most powerful instruments on a HUD in X-Plane.

Instead of showing where the aircraft’s nose is pointing (pitch and yaw), the velocity vector shows where the aircraft is actually physically moving relative to the outside world.

If there is a crosswind from the left, the velocity vector will be displaced to the right of the aircraft’s centerline/boresight cross.

To fly a precise ground track, you keep the velocity vector locked onto the desired meridian or runway extended centerline, rather than the nose symbol.

Too many active AI aircraft plays havoc with ATC

In the constant search for realism it is tempting to activate more than three AI aircraft. This can lead to all sorts of troubles with ATC.

Apart from your own aircraft there are three other possible types of aircraft found at an airport:

Static aircraft – These are simply non moving models and use very few resources. The just make the airport seem fuller.

Traffic aircraft – there are a number of traffic addons available – both freeware and payware which are controlled by the traffic add-on they are paired with. They move, taxi, take off and land but they are actually not connected to the X-Plane ATC system at all. They have relatively little effect on X-plane’s performance.

AI Aircraft – These are aircraft that are controlled by X-Plane’s ATC – with ever increasing intelligence. They are essentially the default aircraft of X-Plane itself. They even talk to ATC. The problem is that each additional aircraft uses a lot of extra resources and this extra load first becomes noticeable when ATC has long pauses before giving you instructions. Too many active AI aircraft also make conversation with ATC difficult because there is much more chatter, and you have to find a gap to send your message.

One or two AI aircraft should suffice with an absolute maximum of 3.

No more “Open Checklist” in X-Plane file menu

Did you notice that there is no more “Open Checklist” in the File menu drop-down of X-Plane12? I didn’t even notice when it was actually removed. True, it was a little limited, but for those who want to keep their installations “plugin free” that option just isn’t there anymore.

However, having stated the bad news, all is not lost. I presume one of the reasons for the removal is that there is a very good – very stable – absolutely no trouble – freeware – plugin available called XChecklist created by @sparker . If you have never seen this plugin, download it and try it out. There are many, many checklists published on this forum which are compatible with X-Checklist, so you are are bound to find one for your favourite aircraft. In fact, it is very easy to create your own checklist with nothing more than a humble text editor.

The plugin will work on Windows, Mac and Linux. And the good news is that it is far more capable than the original Laminar checklist.

Ground speed fine control – Speedup the sumulation

Although no longer available from the pull-down menus, using the key combination [ALT]+[T] will double your ground speed, effectively relieving the tedium of a long flight.
[ALT]+[T] again will quadruple your ground speed,
[ALT]+[T] again will increase your ground speed 8x,
[ALT]+[T] again will increase your ground speed 16x,
[ALT]+[T] again will bring your speed back to normal (1x)

Did you know, however, that if you open the instructor station (press [I] or click “Show IOS” from the Flight pull-down menu), there is an analog(ue) ground speed slider. This slider allows you to reduce or increase ground speed without having to cycle through the higher speed levels to get back to 1x. It only goes as high as 6x but you can set any speed you like between 0x and 6x. It is particularly useful if you want to slow your ground speed below 1x or increase ground speed only slightly like 1.5x

Cockpit goes dark

This is something which catches most of us at some stage. You are flying merrily along, steadily gaining height and suddenly… “oops” … I must have flown into an eclipse… Everything has gone dark… what did I do wrong now? you ask yourself. Is my PC overheating? … something has gone badly wrong…

No nothing has gone wrong. You are flying a simulator which actually simulates … You need Oxygen… Hypoxia…

You can turn the effect off by un-ticking the checkbox in the Settings –> General page

Finding the Taxi Arrows

When you are parked at a gate, you often cannot see the Taxi Route Arrows once ATC gives you permission to Taxi.

Your first assumption is that there is no taxi-arrow indication available for this airport. However, that is very unlikely. Instead, you may well find that the arrows are behind you or obscured or too far away to see. The solution is to go into Free Camera mode by pressing the image.jpegkey and then use the arrow keys to rise right out of the cockpit and then look around:

Here we find the arrows pointing back behind the aircraft.

When ATC makes no sense…

Did you know that when ATC give you weird instructions, you can actually discover what it has in mind.

Click the menu: Developer –> Toggle Air Traffic Paths. Now, to see what ATC has in mind, bring up the map view window [M] and you’ll see a green line representing the track that ATC wants you to follow.

This “map confirmation” of ATC intentions goes a long way toward re-assuring us that ATC has not forgotten all about us.

Alpha and Beta on a Turboprop Aircraft

When flying a turboprop aircraft like the insanely high-powered Lancair Evolution, in order to taxi effectively you will need to use the power lever (throttle) in sometimes in Alpha and sometimes in Beta thrust ranges.

Alpha range controls a variable prop pitch and is used in normal flight and straight-line taxiing, while Beta range is a prop pitch that is so fine that the propeller has far less effect on forward thrust and is used when using toe brakes to turn. They are both ranges of pitch.

To understand more about what Alpha and Beta power ranges are, go to this thread where @philipp , @SteveDe and @skycycle explain this in much more detail on the X-Plane.org forum.
