| Type | Name | Description |
|---|---|---|
| Criteria | criteria | Choice of ICAO PANS-OPS or FAA TERPS |
Remarks

Methods
ProjectedAltitude(Altitude, LinearDistance, LinearDistance, Nullable<Altitude>)
FAA : To determine the highest altitude within the turn, determine the projected altitude for a known distance.
Declaration
public Altitude ProjectedAltitude(Altitude segmentStartingMSLElevation, LinearDistance d500, LinearDistance d350, Altitude? publishedMaximumMSLAltitude)Parameters
| Type | Name | Description |
|---|---|---|
| Altitude | segmentStartingMSLElevation | Segment starting MSL elevation |
| LinearDistance | d500 | Distance at climb gradient 500 in NM |
| LinearDistance | d350 | Distance at climb gradient 350 in NM |
| System.Nullable<Altitude> | publishedMaximumMSLAltitude | published maximum MSL altitude (cap) if applicable, pass null if not |
Returns
| Type | Description |
|---|---|
| Altitude | Projected altitude in feet |
Remarks
The calculation assumes a climb of 500 ft/NM below 10000 MSL and 350 ft/NM at or above 10000 MSL.
