TD-105

Question 1

What are the wind limitations for the OH-58A/C?

Answer 1

(FTG p.5-6)

• The Helicopter can be started in a maximum wind velocity of 45 knots and a maximum gust spread of 15 knots.

NOTE
Gust spreads are not normally reported. To obtain spread, compare minimum and maximum velocities.

• Maximum wind for hovering is 35 knots cross-wind and 30 knots tail-wind.
• Maximum wind for mooring is 65 knots parallel to the ground in any direction.

Question 2

Define Aerobatic Flight. What aerobatic flight maneuvers are prohibited?

Answer 2

(OP SUP p.5-10)

• Aerobatic maneuvers are PROHIBITED. Areobatic flight is defined to be any intentional maneuver involving an abrupt change in aircraft attitude, abnormal attitude pitch angle greater than 30 degrees or roll angles greater than 60 degrees, or abnormal acceleration not necessary for normal flight.

Question 3

What control movements are prohibited? What is the CAUTION associated with control movements?

Answer 3

(OP SUP p.5.10)

• Abrupt control movements, including rapid and repetitive anti-torque pedal reversals.

CAUTION:

• For gross weight greater than 3000 lbs and density altitude greater than sea level, the directional control margin may be significantly reduced while hovering in winds from the right greater than 20 knots or for right sideward flight at speeds greater than 20 knots.

Question 4

What are the flight restrictions at low “Gs”?

Answer 4

(OP SUP p.5-10)

• Flight at less than +0.5g is prohibited.

Question 5

What are the engine tachometer limits for the OH-58A/C?

Answer 5

(OP SUP p.5-3)

• 98 -100% Normal Operation
• 100% Maximum

15 Sec Maximum transient N2 is 110% (Autorotation)

Avoid Steady Sate Conditions Between 78-88% N2
