Straight & Turning Climbs

Introduction to Straight & Turning Climbs

Weight acts in a rearward direction, causing more total drag, requiring increased power
Used to practice take-off
Climb is limited by the thrust available
Normal climb may be called "cruise climb"
Pitch + Power = Performance
WARNING:
All procedures are GENERALIZED.
Use the Pilot Operating Handbook (POH) procedures for specific aircraft performance and limitations.
and/or current Standard Operating Procedures (SOPs).

Straight and turning climbs develop pilot ability to maintain precise aircraft control while gaining altitude.
Climbs require coordinated management of pitch attitude, power settings, airspeed, and trim.
Turning climbs combine altitude gain with heading changes while maintaining coordinated flight and stable climb performance.
Vy provides the best rate of climb while Vx provides the best angle of climb for obstacle clearance situations.
Additional rudder coordination is necessary during climbs due to increased left-turning tendencies at high power settings.
Bank angle, load factor, and increased drag during turning climbs can reduce climb performance and increase stall speed.
Pilots should divide attention between outside visual references and flight instruments during climb operations.
Improper pitch or coordination during climbs may result in airspeed deviations, excessive yaw, or stall conditions.
Wind conditions, aircraft weight, density altitude, and turbulence significantly affect climb performance.
Understanding straight and turning climbs improves aircraft control proficiency, energy management, and overall flight safety.

Straight & Turning Climbs

The best rate of climb, or Vy, occurs where the most excess power is available over that required for level flight
it will produce the greatest altitude gain in the least amount of time

Straight & Turning Climbs

The best angle of climb, or Vx, provides the most altitude gain in the least amount of distance and is considerably lower than Vy

Straight & Turning Climbs

First, set the attitude
- Use visual references you're familiar with like V_x or V_y on takeoff
- If the airspeed is higher than your reference, don't pitch as high, and vice versa
Next, set the power
Finally, make adjustments
- Continue to evaluate and make small corrections, correcting with atttiude vs. airspeed
- If you pitch for the desired airspeed and overshoot, you'll end up chasing the needle

Perform clearing turns
Begin the climb:
- Increase pitch and then increase power (full > 100' to overcome drag
  - The two will be almost simultaneous but remember, Pitch + Power = Performance
- Put the cowling on the horizon during a Vy Climb
- Put the glare shield on the horizon during a cruise climb
- Increase right rudder to overcome propeller effects to the left
- Controllable-pitch propellers will have a manifold pressure gauge in addition to a tachometer
- Increasing the throttle will increase manifold pressure
- Manifold pressure decreases with altitude
- More power will be needed for a climbing turn due to the resultant lift
Adjust Trim
Cross-check Instruments:
- Cross-check the airspeed indicator, attitude indicator, and the position of the airplanes nose to the horizon to determine correct pitch attitude
- Heading should be constant with wings level for a straight turn
- Climbing turns should have a constant angle of bank and rate of turn:
  - Shallow (less than 20 degrees)
  - Medium (20 degrees to 45 degrees)
  - Steep (45 degrees or more)
- Adverse yaw and coordinated flight should be considered in turning
Level-off:
- Level off 10% of the rate of climb before your desired altitude (500 fpm would make 50 feet early)
- Climb power should be retained temporarily so that the airplane will accelerate to the cruise speed more rapidly
- When the desired speed is reached, decrease throttle and re-trim the aircraft and adjust mixture

Straight & Turning Climbs

For any maneuver of condition of flight, the pitch, bank, and power control requirements are most clearly indicated by certain key instruments
Those instruments which provide the most pertinent and essential information will be referred to as primary instruments
Supporting instruments back up and supplement the information shown on the primary instruments

Straight & Turning Climbs

Failure to adequately clear the area, as appropriate
Attempting to establish climb pitch attitude by referencing the airspeed indicator, resulting in "chasing" the airspeed
Applying elevator pressure too aggressively resulting in an excessive climb angle
Applying elevator pressure too aggressively during level-off resulting in negative "G" forces
Inadequate or inappropriate rudder pressure during climbing turns
Allowing the airplane to yaw in straight climbs usually due to inadequate right rudder pressure
Fixation on the nose during straight climbs, resulting in climbing with one wing low
Failure to initiate a climbing turn properly with use of rudder and elevators, resulting in little turn, but rather climb with one wing low
improper coordination resulting in a slip which counteracts the effect of the climb, resulting in little or no altitude gain
Inability to keep pitch and bank attitude constant during climbing turns
Attempting to exceed the airplane's climb capabilities

Remain mindful that performance calculations are usually more optimistic than actual performance
Consider actual versus realized performance when doing any performance calculations
Consider practicing maneuvers on a flight simulator to introduce yourself to maneuvers or knock off rust
