How To: Fly Vectors Part 1 Lateral Navigation, Page 1 of 2 - TGISкод для вставки
This one deals with flying vectors under ATC control . It only deals with lateral vectors, vertical changes will be covered in a later How To. The route is fictitious and I have ignored any altitude constraints on any airways, SIDS etc so donвЂ™t get picky ;) How To: Fly Vectors Part 1 Lateral Navigation, Page 1 of 2 1. Basic Setup. WeвЂ™re on our route with LNAV and VNAV engaged Example is Level D 767, it works the same with all Boeing. The same principles apply to Airbusses but you press different buttons! v.5 dated 28/11/10 TIP: Note that I keep my Heading Bug aligned with the direction of route, if you do that then you will always be ready for a quick вЂњright 5 degreesвЂќ that the controller might give you because it means less knob twiddling! So, each time your route changes direction, just re-align the heading bug Your EADI confirms that you are settled on LNAV and VNAV with CMD engaged 2. ATC give you an instruction вЂњTurn right heading 340 degreesвЂќ. This takes you off route . First adjust your heading bug to 340 degrees with LNAV still engaged. The EHSI now shows the intended heading. You can always go straight to the next step and miss this one but there is the risk that you dial in the wrong heading when already on HDG SEL! By setting it before disengaging LNAV you get a brief chance to check it. Now PRESS the HDG Select button (where it says SEL). The LNAV light extinguishes. The EADI changes from LNAV to HDG SEL. You are now flying a вЂњRadar HeadingвЂќ and if you get handed off to another controller you should tell him straight away вЂњRadar heading 340вЂќ so he knows youвЂ™re not flying the planned route. You are now set up for any further heading changes they give you, simply bung them into the HDG dial and the aircraft will turn accordingly. (c) Bill Casey, 2009, 2010. For Vatsim-UK. Not for real world navigation (or to be nicked by other networks) The aircraft has now turned to the selected heading. Note that with the crosswind the Heading is NOT the same as the Track but you have been told to fly a Heading, not a Track. Follows on from Page 1 where we had set up the aircraft on a Radar Heading, so weвЂ™re on Heading Select, 340 Degrees, with VNAV engaged. How To: Fly Vectors Part 1 Lateral Navigation, Page 2 of 2 3. ATC tell you вЂњResume own navigation direct to SAPCOвЂњ. This bypasses your next waypoint of WELIN. Example is Level D 767, it works the same with all Boeinga. The same principles apply to Airbusses but you press different buttons! Press the key next to SAPCO, this puts it in your scratchpad v.5 dated 28/11/10 Now press the key next to the waypoint at the top of the route (was WELIN) and it replaces it with SAPCO. EXEC illuminates. Once we have EXECuted that, the EHSI shows the new route direct to SAPCO but weвЂ™re still heading 340. The EADI still shows HDG SEL, LNAV is still off. The whole route has now shifted up one place so we have just missed out WELIN. Press EXEC. 4. So, to вЂ�Resume Own NavigationвЂ™ having taken the above steps we MUST go back to LNAV. IвЂ™m stressing that because it is DEAD easy to forget to re-engage LNAV and keep bimbling away on a Heading! Press LNAV, the light comes back on, the aircraft starts to turn Direct To SAPCO and the EADI confirms youвЂ™re back on LNAV. Now is a good time to re-align your heading bug (pointing to SAPCO) ready for the next interfering controller to take you off route again! Simples! If you now get handed off to another controller, in your first call tell them that you are вЂњDirect SAPCOвЂќ or they may be expecting you to go via WELIN first since that was your planned route. (c) Bill Casey, 2009, 2010. For Vatsim-UK. Not for real world navigation (or to be nicked by other networks) This process is the same anytime you get a вЂњDirect ToвЂќ whether you were on a heading or flying the programmed route. Move the desired waypoint to the top of the route, EXEC and make sure youвЂ™re on LNAV. Direct To off-route waypoints. If youвЂ™re sent to a Direct To waypoint that is NOT on your route (assuming ATC havnвЂ™t made a mistake!) then type it into the scratchpad, place it to the top of the route and press EXEC.
