Editing Align MFD

'''AlignMFD''' is an MFD mode designed to allow the pilot to align the ship's orbital plane with that of a target orbital plane. It indicates orbital elements of the ships current and target orbits, relative inclination of the two orbits, the angles of the current radius vector from the ascending and descending nodes and estimated burn time to zero out the relative inclination. The target plane can be the orbital plane of a target body or vessel, or another orbital plane.

AlignMFD is called by selecting it from the SEL button below the desired MFD display or by the hot key  {{Key|LeftShift}}+{{Key|A}} for the left display or {{Key|RightShift}}+{{Key|A}} for the right display.

Control buttons are:
*'''REF''':Brings up a menu list of reference bodies.
*'''AR''':Automatically selects the body with the highest gravity potential on the ship as reference, i.e. the body the ship is orbiting.
*'''TGT''' {{Key|Shift}}+{{Key|T}}:Allows the user to select a target's orbit to align with.
*'''ELS''' {{Key|Shift}}+{{Key|E}}:Allow the user to input a custom orbit to align with.

-==On screen data==
-*'''Inc''': Orbit inclination of ''Current'' (your ship) and ''target''
-*'''LAN''': Longitude of the Ascending Node of ''Current'' (your ship) and ''target''
-*'''RInc''': Relative inclination between current and target orbits, in degrees
-*'''Rate''': How fast the current orbital plane is changing, in degrees per second
-*'''AN''': Ascending node
-*'''Tn''': Number of seconds until the next node
-*'''TthA''': estimated number of seconds until alignment during the next burn at the next Ascending node
-*'''TthD''': estimated number of seconds until alignment during the next burn at the next Descending node
-Alignment burns should be done near the nodes. Near the Ascending node (AN), rotate the ship to Normal- (antinormal), and near the Descending node (DN), rotate the ship to Normal+ (normal).
-== Operation ==
-*Using the SEL button on any MFD display, select '''Align Planes'' ({{Key|Shift}}+{{Key|A}}.
-*Using the TGT button or {{Key|Shift}}+{{Key|T}}, select a target from the menu or type in a target name.
-*Note '''RInc''', just under "Relative". Looking at the graphics, if your ship is approaching the DN node, rotate the ship to Orbit Normal (NML+), if your are approaching the AN node, rotate to Orbit antinormal (NML-). The way to remember this is '''''A'''scending node and '''A'''ntinormal both begin with the letter A''.
-*Note the Est Thrust T - TthA is for near the ascending node, TthD is for near the descending node. When your Tn reaches half of the TthA or TthD value, engage full thrust, the message box at the lower left of the display will also tell you to engage thrusters. After you pass the node, continue thrust until either RInc reaches zero or node line begins to move rapidly, or the message in the lower left says '''KILL THRUST''', stop firing. At the next node, rotate to NML + or -, then burn again about half the remaining thrust time required. You can also use retros to correct an overshoot and RCS to fine tune the RInc.
-*Once you zero the RInc or near to it, you are done with this MFD mode.
-*If you are chasing a target, the next MFD mode is '''Sync''' MFD, '''Transfer''' MFD, or your favorite autopilot, such as '''TransX''' or '''IMFD'''.
