The base length of the runway at the mean
sea level (MSL) is 1500 m. If the runway is
located at an altitude of 300 m above the
MSL, the actual length (in m) of the runway
to be provided is
(round off to
the nearest integer)

What is the distance in km between the emergency landing site and the airport?arrow_forwardAn airport is to be constructed at a site 190m above mean sea level and on a level ground. The runway length required under standard atmospheric condition at sea level for landing is considered as 2100m and for take-off as 1600m respectively. Determine the actual runway length to be provided at this airport site. Airport reference temperature may be considered as 21-degree C.arrow_forward
