| Key | Meaning | Rules | Examples |
|---|---|---|---|
| IAS | Indicated Air Speed | Units in knots. Integer value This is intended as a fixed IAS selected beteen this and next point If not set in a point is the derived from prior IAS KEY is not compatible with GS nor TAS keys but one of them must be defined or derived from earlier points | IAS: 100 IAS: 230 |
| TAS | True Air Speed | Units in knots. Integer value This is intended as a fixed TAS selected beteen this and next point If not set in a point is the derived from prior TAS KEY is not compatible with GS nor IAS keys but one of them must be defined or derived from earlier points | TAS: 100 TAS: 230 |
| GS | Ground Speed | Units in knots. Integer value This is intended as a fixed GS selected beteen this and next point If not set in a point is the derived from prior GS KEY is not compatible with IAS nor TAS keys but one of them must be defined or derived from earlier points | GS: 100 GS: 230 |
| FL | Flight level | Units in hfts. Integer value This is intended as FL selected beteen this and next point If not set in a point is the derived from prior FL KEY is not compatible with AGL key but one of them must be defined or derived from earlier points | FL: 340 FL: 400 |
| AGL | Altitude over ground level | Units in hfts. Integer value This is intended as AGL selected beteen this and next point If not set in a point is the derived from prior AGL KEY is not compatible with FL key but one of them must be defined or derived from earlier points | AGL: 010 AGL: 030 |
