groundspeed การใช้

• Remember-your calculations relate to AIRspeed-not GROUNDspeed.
• His actual flight time was 18 hours and 20 minutes, at an average groundspeed of.
• The detour to North Platte also resulted in Maughan encountering a strong headwind, slowing his average groundspeed.
• By comparing the fix and the estimated position corrections are made to the aircraft's heading and groundspeed.
• Aircraft flight instruments, however, don't compute true airspeed as a function of groundspeed and windspeed.
• Positional information was given by a Doppler navigation system which read groundspeed and drift data which, alongside heading data, drove the stylus.
• From the controls, I could tell that we were flying at groundspeeds that fluctuated with the winds from 140 to 165 miles an hour.
• Reverted rubber aquaplaning is insidious in that the pilot may not know when it begins, and it can persist to very slow groundspeeds ( 20 knots or less ).
• The wind triangle is used to calculate the effects of wind on heading and airspeed to obtain a magnetic heading to steer and the speed over the ground ( groundspeed ).
• For aerodynamic aircraft which operate relative to the air, winds affect groundspeed, and in the case of lighter-than-air vehicles, wind may play a significant or solitary role in their movement and ground track.
• Naturally we must apply these corrections to our groundspeed in the appropriate direction according to logic-a wind from the left will blow us off course in that direction; a headwind will slow our progress, a tailwind will increase it.
• At 13 : 43 hours local time ( 05 : 43 UTC ) and 11 minutes after declaring the " Mayday ", the crew landed the aircraft on Chek Lap Kok's Runway 07L at a groundspeed of 426 kilometres per hour.
