WWW.SURVIVALEBOOKS.COMfrom bomb shackles on the wings and can be droppedwith a high degree of accuracy from low altitudes.(d) Due to their relatively slow speed and high maneuverability, transport airplanes can fly safely and efficientlyat a low altitude.(e) Landings and takeoffs at night can be made with aminimum of lighting.(/) Large internal loads can be transported in rear ramploading aircraft.(2) Limitations.(a) Transport airplanes require larger and more improvedlanding areas than helicopters.(b) Hail, sleet, icing, heavy rains, and gusty winds (30knots or more) may limit or preclude their use.(c) A wind velocity above 10 knots normally affects theselection of the direction of approach and landing.c. Special Considerations. The factors mentioned in b (2) (a)and (b) above are variable. Commanders of supporting aviationunits provide specific data for each type aircraft and operation.d. Reference. For specific capabilities of current types of Armyaircraft, see TM 57-210.18. Night and Low Visibility Operationsa. Operation Requisites. Normally, transport aircraft can operate when(1) The ceiling permits safe flying above the highest terrainto be traversed.(2) There is enough forward visibility for the pilot to seeobstacles in time to avoid them when flying at reducedspeeds.(3) There is enough visibility for the pilot to distinguishprominent landmarks.6. Advantages of Night Operations. Darkness offers concealment for the transport aircraft from enemy visual observation andprotection from enemy aircraft.c. Disadvantages of Night Operations.(1) The necessity for more elaborate control measures andfor caution on the part of pilots and passengers slowsdown night operations. Operations may be further prolonged when it becomes necessary to fly the aircraft singlyrather than in a compact formation.AGO 2294B 1 1
