PERFORMANCE
With an assumed headwind of 20 kts enroute, the ground speed for
cruise is:
117
-20
= 97 kts
Usingthesetwovalues,thetimeforthecruise can be calculated:
267 NM / 97 kt=2.8 h
Thefuelrequiredforcruise is:
2.8 h x 28 l/h =78.4 l
45-minutereserve:
45/60 x 28 l/h = 21 l
Nextthe total fuel required can be calculated as follows:
Enginestart,taxi,andtakeoff 4.0 l
Climb 6.4 l
Cruise 78.4 l
Reserve 21.0 l
For estimating the landing distance at the destination airfield, a
proceduresimilartotakeoffshould be used.
For this fig. 5-12 "Landing Distance (for short fields)" is to be used. The
