JET BLAST
When maneuvering on the ramp area special caution must be taken to avoid jet blast damage.
Use the following technique when maneuvering on the ramp area:
•
Apply thrust to a maximum of 1.2 EPR.
•
Retard both throttles as soon as the aircraft starts rolling.
•
If a tight turn is required, leave the power on at 1.2 EPR until the point where jet blast
could cause damage, then close both throttles. This should give the aircraft sufficient
momentum to sustain taxi out of the congested area.
•
If 1.2 EPR is not sufficient to move the aircraft out of a gate area where there is danger of
jet blast damage to ground equipment, the Captain should request a tow-out.
Zone 1:
During breakaway power, the jet blast in zone 1 is powerful enough to up-root trees, cause
structural damage to other aircraft, tip over and move heavy objects and break windows.
Zone 2:
During breakaway power, the jet blast in zone 2 is strong enough to weathercock unbraked
aircraft, sway lift trucks, damage roofing and move unsecured objects.
Zone 3:
During breakaway power, the jet blast in zone 3 can move unbraked carts and small objects.
