Hi guys.
I hope some one in here can help me out here.
I am to teach ATPL performance and have run into a question I can't solve or understand.
The question is:
For a turboprop powered aeroplane, a 2200 m long runway at the destination aerodrome is expected to be "wet". To ensure the wet landing distance meets the requirements, the "dry runway" landing distance should not exceed:
a) 1540 m
b) 1147 m
c) 1339 m
d) 1771 m
The rules says:
Landing distance required on a dry runway for destination and alternative aerodromes, from 50' to full stop must not exceed :
70 % of LDA for turboprop aeroplanes.
If the runway is forecast to be wet at the estimated time of arrival the landing distance available must be 115% of landing distance required.
I have the answer but I dont understand why because of the way the rules are descriped.
Can anyone give me a good explanation ??
Thanx for your help !
