• Following a takeoff limited by the 50ft screen height a light twin climbs on a gradient of 5%. It will clear a 160m obstacle in relation to the runway (horizontally), situated at 5000m from the 50ft point with an obstacle clearance margin of:
a) it will not clear the obstacle
b) 105m
c) 90m
d) 75m
5% of 5000m = 250m
50 ft = 15.6 m
250m + 15.6m = 265. 6m
265.6m - 160m = 105.6m
So B is the right answer.
With a TAS of 194kts and a vertical speed of 1000ft/min the climb gradient is about
a) 3degrees
b) 3%
c) 5 degrees
d) 8%
1000 ft * 60 = 60000 ft
60000 ft / 6080 = 9.86 NM
X * 194/60 = 9.86
X * 3.23 = 9.86
X = 9.86/3.23
X = 3
So A is the right answer. It is only a 1 in 60 rule.
• During certification flight testing on a four engined turbojet a/c the actual TOD measured are:
3050m with failure of critical engine
2555m with all engines operating and all other things being equal
The take off distance adopted for certification file is:
a) 2938m
b) 3050m
c) 3513m
d) 2555m
2555 * 1.15 = 2938.25
3050
the right answer is the bigger one for safety reasons. So B
About the accelerated stop distance A is the correct one.
Sorry that Im not ale to help you with the first question. I dont have the CAP.
