单选题
If the aircraft points into the wind and wind speed is between 50 and 70 Kts, moor the aircraft at the NLG.If the aircraft does not point into the wind or the direction of the wind is not stable,for wind speeds or gusts more than 50 Kts, moor the aircraft at the NLG and the MLG.
A
If the wind speed is between 50 and 70 Kts and the aircraft is down the wind, secure the aircraft at the NLG (nose landing gear). However, if the aircraft is not down the wind or if the wind direction is unstable and wind speeds or gusts are more than 50 Kts, then secure the aircraft at both the NLG and MLG (main landing gear).
B
If the wind speed is between 50 and 70 Kts and the aircraft is down the wind, the mooring point shall be at the NLG (nose landing gear). However, if the aircraft is not down the wind or if the wind direction is unstable and wind speeds or gusts are more than 50 Kts, then secure the aircraft at both the NLG and MLG (main landing gear).
C
If the wind speed is between 50 and 70 nautical miles/hour and the aircraft is up the wind, the mooring point shall be at the NLG (nose landing gear). However, if the aircraft is not up the wind or if the wind direction is unstable and wind speeds or gusts are more than 50 nautical miles/hour , then secure the aircraft at both the NLG and MLG (main landing gear).
