DASH ONE - SECTION 6 + 7 Flashcards
How is STALL RECOVERY accomplished at first?
“Stall recovery is accomplished by easing the stick forward to lower the nose and simultaneously applying full power to fly the aircraft out of the stalled condition.”
RECOMMENDED AEROBATIC MANOEUVRES
Entry speeds (IAS)
Loop
Lazy eight
Chandelle
Loop - 140 knots
Lazy eight - 130 knots
Chandelle - 130 knots
Before starting any aerobatics, what must be done?
- Auxiliary fuel pump - ON
- Fuel selector turned - BOTH ON
- RPM - 2500 RPM
When diving what should you look out for, and how do you prevent this?
- Over speeding the engine
- Exercise extreme care when increasing the power
How many turns in spin does it take, before it becomes stationary?
2 turns
What is the rate of rotation and the altitude loss during the stationary spin?
- Rate of rotation of 2.5 sec/turn
- Altitude loss of approx. 300 -
400 ft/turn
What is the average total loss of altitude during a spin?
2500 ft after entry, 6 turns of spin and recovery
SPIN RECOVERY
First 2 steps?
- Throttle idle
- Flaps up
How can you determine if a spin is erect or inverted?
“The pilot can recognize if the spin is erect or inverted by the positive or negative load factors”
In other words read if you’re pulling positive or negative “G”
How can you determine spin direction?
“Determine spin direction by the needle of the turn and slip indicator or by observing the ground over the nose. “
When in an inverted spin, what is the best way to determine spin direction?
“To observe the ground through the canopy in an inverted spin will give you a false indication of spin direction. Therefore, the most reliable indication of the spin direction is the turn-needle.”
ERECT SPIN
What is the procedure for erect spin, after it’s been determined?
A) Apply full opposite rudder. Ailerons neutral
B) Ease stick forward
C) When rotation of the spin stops, centralize the rudder
D) Apply gentle back pressure at 80 - 100 knots to recover from the dive and resume normal flight
INVERTED SPIN
What is the procedure for inverted spin, after it’s been determined?
A) Apply full opposite rudder. Ailerons neutral
B) Apply back pressure
C) When rotation of the spin stops, centralize the rudder
D) Roll out the aircraft to resume erect flight and apply gentle back pressure to resume normal flight
Recovery is normally done within one additional turn. If, however, the control stick is pressed too violently ___, an increase in rate of rotation will occur which will delay the recovery by
___.
- Forward
- 1 - 2 turns
Never use __ in an asymmetric flight condition as the __ effectiveness will be marginal.
- Flaps
- Roll
TURBULENCE AND THUNDERSTORM
What is written about severe turbulence?
Flying in severe turbulence should be avoided.
If this is not possible, all occupants shall tighten their safety belts.
Do not increase the load factor by steep turns or other violent maneuvers
What does “cold weather” generally refer to?
Temperatures below 0 °C unless otherwise specified
What should be done, if the aircraft has been parked outdoors and accumulation of frost, ice or snow has formed on lifting surfaces or any other surface that may adversely affect performance?
Such accumulations must be removed before take-off
What should you not use on the aircraft surface or canopy, to remove frost, ice or snow?
Mechanical scrapers
When de-icing the aircraft, what should be done, avoided and what is prohibited?
The pitot tube cover must be installed while spraying
Avoid spraying fluid into the static and dynamic pitot system
Spraying the areas around the static holes on the fuselage is prohibited
At temperature below –15 °C, what should you do before starting engine?
Engine oil should be preheated
During flight in temperatures below ___, cycle propeller about every ___ to help prevent freezing of the oil in the propeller dome.
- 0 °C
- 30 minutes
During take-off in cold weather with accumulation of ice or snow, what should you be cautious about?
The take-off distance and climb performances can be seriously affected
In this manual warm weather refers to what?
Temperatures above +40 °C
Take-off and landing in warm weather may affect what?
That the distance for takeoff and landing will be longer than normal
During taxiing and climb in warm weather, what should be done to avoid vapor-locks forming in the fuel lines?
The auxiliary fuel pump should be ON
In warm weather, roughness or reduction of power may occur at ___ mixture. In that case, lean according to
___ procedure.
- Full rich
- BEST POWER
Maximum speed in turbulence?
Vno - 154 knots
Why should you close ALT AIR slowly ?
To see how the engine reacts
If abnormal engine operation is experienced ALT AIR should be opened
