Aerobatics

=Discuss= After you finish Fams and your solo (which should have been a lot of fun), PA's will seem like a vacation. It is a bit front-loaded, as you have about 8 new maneuvers to learn for the first flight, but they're easy, and you do the same thing every flight. Every other flight is a solo, so it's nice and relaxed. The "safe-for-solo" flights are nothing like your C4390; the instructor will just make you spin, stall, and UA recover. Make sure you wave off at least once in the pattern. Enjoy these flights, because it's the last time during Primary where you won't be studying for every flight.

Aerobatics Select working area with ground references and section lines Call working area on area common Squawk 4700 Enter Aerobatic Cruise--1015# Climb to ~7500’ MSL Perform Aerobatic Checklist 1. Bilges--Clear of Loose Objects, Control Lock Stowed in Two Places 2. Restraint Harness--Adjusted, Tight and Locked 3. Autoignition--ON 4. Engine Instruments--Checked 5. Report--Aerobatic Checklist Complete Anti-G Straining Maneuver G-LOC Grayout Blackout Loss of Consciousness (typically 15-30 secs) Impairment of pilot skills up to 30 mins

HOOK Maneuver Tense muscles Close respiratory tract at 2.5 - 3.0 second intervals

OCF Recovery Positively Neutralize Controls. PCL--IDLE. Determine Aircraft Altitude. Determine AOA, airspeed, and check turn needle. Execute spin recovery technique if appropriate. Erect: 80-100 KIAS, 30 Units AOA, TN Pegged Gear/Flaps--UP Full Opposite Rudder Stick Forward of Neutral When spinning stops recover from nose low attitude Inverted: 0 KIAS, 2-3 Units AOA, TN Peggged, -1g Gear/Flaps--UP Full Opposite Rudder Stick Neutral When spinning stops recover from unusual attitude Execute unusual attitude recovery as appropriate.

VFR Unusual Attitudes Nose Low PCL--IDLE Level Wings Pullout (24 units AOA, 4.5g max) Nose High Roll towards 90o Use bottom rudder As nose goes through horizon, roll wings level Recover to level

Precision Landings Precise patterns At selected point (in the box--abeam to 500’ down runway)

AOA Approaches 20 Units is 35% above stall AOA Using normal interval call crosswind AOA Approaching upwind numbers PCL to 300#, slow to 20 units AOA (~80 / 95 KIAS FF / NF) 500# to maintain 20 units and amber donut Abeam intended point of landing PCL to 300# (275# NF) Just prior to intended point of landing, transition to normal flared landing on final

Airborne Damaged Aircraft Warning: If out of control flight occurs execute OCF RECOVERY procedures. 4. Fly a wide or straight-in approach and land as soon as possible. Lost Aircraft (PCL p. 120) 1. Confess 2. Climb (gives better view, enhances radio comms, conserves fuel) 3. Communicate 4. Conserve 5. Comply with appropriate procedures and instructions
 * 1. Maintain control of aircraft, if not controllable, BAIL OUT.
 * 2. Climb--AS REQUIRED.
 * 3. Check flight characteristics above 5,000’ AGL in the landing configuration, decreasing airspeed in increments of 10 KIAS to an airspeed at which a safe landing can be made (no slower than 80 KIAS).

Securing the Rear Cockpit (PCL p. 109) When securing parachute go under metal cable housing loops a. Restraint harness, parachute and oxygen equipment---SECURE b. Cockpit lights---OFF c. Switches---	BATTERY ON INVERTER NO. 2 ON				ALL OTHER AS REQUIRED d. Inspect for and secure loose equipment e. Aft canopy---CLOSED AND LOCKED

Maneuvering Speed Maneuvering speed (Va) is the max speed at which full control deflection can be abruptly applied without overstressing the aircraft. Va depends on aircraft weight and at max gross weight with flaps up is 135 KIAS.

One-Half Cuban Eight First half of loop followed by 180o roll with nose at 30o down Perform stall checklist Set Aerobatic Cruise Enter so as not to go below 5000’ (requires 1500’, recommend 7500’ MSL)

Do math for pullout (600-700’ above entry altitude) Perform clearing turns, during last 90o lower nose to accel to 200 KIAS 3.5 g pull in 2-3 sec Right rudder at top Approaching 30o nose low (FCP heels on horizon) roll about point in windscreen, and hold nose down at 45o as airspeed increases Start pullout at 600-700’ above entry altitude

C4503
Solo. Grab the stick and yank it around for 1.5 hrs. Don't hit anyone and you'll come back a champ.

C4504
Any Emergency

Split-S
180° roll with nose slightly above horizon followed by second half of loop, should recover ~1500’ below entry altitude
 * Perform stall checklist
 * Set Aerobatic Cruse
 * Enter so as not to go below 5000’ (requires 1500’, recommend 7500’ MSL)
 * Perform clearing turns, during last 90o PCL to IDLE and slow to 130 KIAS
 * Raise nose to exhaust stacks on horizon and roll inverted
 * Momentary delay while inverted
 * Pull wings level
 * Check oil pressure
 * Resume Aerobatic Cruise

Immelmann
First half of loop followed by 180° roll to level, should recover 1500’ above entry altitude
 * Perform stall checklist
 * Set Aerobatic Cruise
 * Enter so as not to go below 5000’ (requires 1500’, recommend 7500’ MSL)
 * Perform clearing turns, during last 90° lower nose to accel to 200 KIAS
 * 3.5 g pull in 2-3 sec
 * Right rudder at top
 * Approaching 20° nose high (canopy bow on horizon), relax backstick and roll with first opposite then pro rudder (as wings go through vertical)
 * Airspeed ~100 KIAS

Solo. Grab the stick and yank it around for 1.5 hrs. Don't hit anyone and you'll come back a champ.

C4601
Busy flight as it serves as both the beginning and end of a new block. This means you'll have to squeeze in a AOA, FF, and NF landing, as well as fly the ELP once (either HAPL or PEL) and knock out a PEL(P) or LAPL(P). Not bad because you're so shit hot by this point in the syllabus right?

C4602
Last PA Solo. Grab the stick and yank it around for 1.5 hrs. Don't hit anyone and you'll come back a champ ready for Formations.
