What are the possible effects of jet blast?
Before a crew can say “powerback,” jet engine blast can up-root trees, flatten building structures, shatter windows, lift and propel heavy objects, weathercock braked airplanes, blow over lift trucks, shift unbraked baggage carts, and create other havoc on airport ramps, taxiways, and runways.
Is a jet safer than a prop plane?
Turboprop vs Jet Safety Both turboprops and jets are powered by turbine engines, so they are essentially the same thing and thus, are considered to be equally as safe. Because of the drag propellers cause, they actually allow the aircraft to stop much more quickly than a jet.
Why was there no warning of jet blast hazard?
Several pilots admonished Ground Control for not monitoring run-ups of larger aircraft more carefully, and for failing to provide light aircraft with warnings of jet blast hazard: “Ground Control cleared me to taxi to my parking area.
What are the usual targets for jet blast?
No. of Rpts. The usual targets of jet blast in these locations were light aircraft, weighing 5,000 pounds or less, that were unexpectedly crunched and pummeled by the blast forces from jet engines. Frequently, the jet blast damage was the result of misdirected engine run-ups and tests.
Why are jet engines dangerous to the ground?
The most significant was the position of jet engines in relation to gates, ground equipment, people, and other aircraft on the ramp when breakaway power was applied. Another prominent factor was the proximity of light aircraft, including commuter-type aircraft, on or near ramps with turbojet operations.
What should ground controllers do about jet blast hazard?
The need for Tower and Ground Controllers to carefully monitor jet blast hazard, specifically the direction of jet engine exhaust. Both themes were dramatically evident in this controller’s report of a large jet’s engine run-up calamity: “Air carrier LGT [large transport] called Ground Control for a full power engine runup at the gate.
