3. Speed Flashcards
Speed measured relative to the airmass through which an aircraft is moving is known as …….. whereas speed measured relative to the ground is known as ……..
airspeed; groundspeed
When an aircraft flies at 100 kt directly into a steady headwind of 20 kt, its indicated airspeed will be …….. kt and its groundspeed will be …….. kt.
100; 80
Assuming a constant IAS, the TAS will (increase / stay the same / decrease) as we climb to altitude.
increase
Assuming a constant IAS, the TAS will (increase / stay the same / decrease) with a rise in temperature.
increase
The term ‘velocity’ implies both …….. and ……..
speed; direction
The heading/true airspeed vector is symbolised by a …….. headed arrow.
single
The movement of an airmass relative to the ground is called ……..
wind
The wind direction, by convention, is the direction (to / from) which the wind blows.
from
The actual path of an aircraft over the ground is called its …….. …….. ……..
track made good (TMG)
The speed of an aircraft relative to the ground is called its ……..
groundspeed
The direction in which an aircraft points is called its ……..
heading
The angle between the direction an aircraft is pointing (i.e. its heading) and the direction in which it is travelling over the ground (i.e. its track made good) is called the …….. angle
drift
Sometimes the actual drift experienced in flight differs from that expected and the aircraft makes good a track that is different to that planned. The difference between the planned track and the TMG is called the …….. ……..
track error
Drift is the angle between …….. and …….. whereas track error is the angle between …….. and ……..
HDG; TR; TR; TMG
The wind velocity calculation has shown that you will experience a headwind component of 18 kt. Is this expressed as a + or - wind component.
minus (-)
