Altitude explained

As you may or may not know, flight model of Kings Angels is based on X-wing system, with its planning the move, revealing and executing combat order. However, for in depth feel of dogfight change of altitude is an essential thing. So after some consideration I've created a module witch expands original x-wing rules. 

To represent altitude echelons in game terms I took following model: 

Deck – close to ground to 1000 meters
Hill – up to 3000 meters
Mountain – up to 9000 meters
Top – up to 16000 meters
Ceiling – up to 24000 meters
Edge – up to 30000 meters, or edge of atmosphere.

All measurements are approximate, as table top game will not be able to represent all details of air movement and combat. (Then again, does it have to?) Aircraft flight card has its top altitude present on the card. If it's presented with red or grey box, then flying on this altitude requires additional test from pilot and/or aircraft. Demand explanation from GM :)  

Altitude and combat.
Aircraft on same altitude may attack each other if target is in range. If target is on different altitude then it can be spotted but no shots can be made. (Unless GM have a different idea or situation allow that to happen.).

Changing altitude.
In order to change its altitude pilot must make a note on his flight card, usually with arrow pointing from his current altitude to what echelon his going, and make a move of 6. This move could be any allowed to aircraft, even stressful. Move may be split between rounds of combat, for example in one round aircraft goes ahead 4, and in following hard turn 2. For as long as pilot keep noting that he is going up or down, plane will change its altitude. Obviously aircraft cannot climb higher than its flight card allows. 

Note that Tempest can climb to Top, but will require additional test to perform without problems.
