FOREWORD
This Indian Standard was adopted by the Bureau of Indian
Standards, after the draft finalized by the Aircraft Handling
Sectional Committee had been approved by the Heavy Mechanical
Engineering Division Council.
In preparation of this standard, assistance has been derived
from the following publications:
AHM 910 Basic requirements for aircraft ground support
equipment, issued by International Air Transport Association
(IATA), Canada
AHM 913 Basicsafety requirements for aircraft ground support
equipment, issued by International Air Transport Association
(IATA), Canada
AHM 915 Standard controls, issued by International Air Transport
Association (IATA), Canada
In reporting the results of a test or analysis made in
accordance with this standard, if the final value, observed or
calculated, is to be rounded off, it shall be done in accordance
with IS 2 : 1960 ‘Rules for rounding off numerical values
(revised)‘. The number of significant places retained in the
rounded off value should be same as that of the specified value in
this standard.
