- (C) 30°
- (D) 40°
2. Consider the following statements regarding ICAO recommendation for correction to basic runway length
- 1. The basic runway length should be increased at the rate of 7 percent per 300 m rise in elevation above the mean sea level.
- 2. The basic runway length after having been corrected for elevation should be further increased at the rate of 1 percent for every 1°C rise in airport reference temperature above the standard atmospheric temperature at that elevation.
- 3. The runway length after having been corrected for elevation and temperature should be further increased at the rate of 20% for every 1 percent of effective gradient.
Of these statements
- (A) 1 and 2 are correct
- (B) 2 and 3 are correct
- (C) 1 and 3 are correct
- (D) 1, 2 and 3 are correct
3. Pick up the incorrect statement from the following:
- (A) Channelization
of pavement is caused by constant use of tri-cycle gears of aircraft
- (B) Blast pads
are used over cohesion-less soils to resist erosion due to tremendous speed of
the jet blast
- (C) Over-run
areas of at least 300 m length on either side of the runway are provided
- (D) None of
these
4. As per ICAO, for A, B, and C type of airports, maximum effective, transverse and longitudinal grades in percentage respectively are

- (B) 1.0, 1.5 and 2.0
- (C) 1.5, 1.5 and 2.0
- (D) 2.0, 2.0 and 2.0

- (C) Reduced
level

above
8. Runway threshold is indicated by a series of parallel lines starting from a distance of
- (A) 3 m from runway end
- (B) 6 m from runway end
- (C) 10 m from runway end
- (D) 15 m from runway end
9. The reduced level of the proposed site of an air port is 2500 m above M.S.L. If the recommended length by I.C.A.O. for the runway at sea level is 2500 m, the required length of the runway is
- (A) 2500 m
- (B) 3725 m
- (C) 3000 m
- (D) 3250 m

conditions
