The utilities are:
  
1.  Crosswind. Enter: wind direction, wind speed, runway QDM, crosswind and tailwind limits. Results: crosswind and head/tailwind components, maximum wind strength before crosswind or head/tailwind limits are exceeded (for the given direction).

2. Density Altitude. Enter: airfield elevation, airfield QNH (hPa), outside air temperature (Centigrade). Results: ISA deviation, pressure altitude, density altitude.

3. Equi-Time Point. Enter: leg distance, groundspeed out, groundspeed home, outbound ground speed (groundspeeds out and home are groundspeeds *after* the engine failure or depressurisation, outbound groundspeed is the groundspeed *before* the failure). Results: distance to ETP, time to ETP.

4. Fuel. Enter: fuel units (US gallons, Imperial gallons, pounds, litres, kilograms), fuel quantity, specific gravity (default SG is 0.8). Results: fuel quantity in all units.
