The Utilities. ------------- 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 for 100LL). Results: fuel quantity in all units. 5. Point of No Return. Enter: start fuel (any units), reserve fuel, groundspeed out, fuel flow out, groundspeed home, fuel flow home, climb fuel, climb distance, descent fuel, descent distance. Results: distance to PNR, time to PNR, fuel remaining at PNR, return time from PNR. N.B. fuel can be in any units (gallons, 1000s of pounds etc.) but fuel flow must be in the *same* units... 6.
