Gross Weight DA Wind Temperature Reaction Time TH-57 Glide Characteristics FTI vs. NATOPS
FTI: Nr maintained at or above 94% => Larger ROD & GS. NATOPS: Assumes 90% Nr Rate of Descent: 1360 1760 fpm (50kias) (72kias) Glide Ratio: 4.1 3.3 (72kias)
Glide Slope 2:1 600 AGL = 1200 (.23 Miles) OTG 300 AGL = 600 (.11 Miles) OTG Entry FTI 70 KTS / 600 AGL Enter the autorotation by smoothly lowering the collective to the full down position and simultaneously adding right pedal to maintain balanced
flight. Reduce twist grip to the flight idle position and turn to the course line. Verbals PAC: Lane, Lock, Sock PAC: Altitude 600 FT, 70 KIAS, VSI AT OR BELOW ZERO, AIRCRAFT IN TRIM PAC: Down, Right, IDLE, Turn. Transition to Final
FTI Transition to 50 to 60 KTS descending attitude. Monitor Nr and control between 90 and 107 % with collective (optimum 94 to 95%). NATOPS PAC: Attitude, Nr, Ball Final FTI Intercept the course line
and establish crosswind correction as necessary. Maintain the 50 to 60 KTS descending attitude. Ensure Collective is full down by 150 feet AGL Verbals PAC: 200 On Courseline PAC: 150 Collective Full Down Flare FTI
At 75 to 100 AGL flare with cyclic in order to reduce rate of descent, reduce groundspeed, and increase Nr. Adjust flare as required to achieve desired groundspeed and minimal rate of descent. Verbals Power Recovery PAC: 100 Flare, Twist Grip Full Open
PNAC: Roger Twist Grip Full Open Full Auto PAC: 100 Flare,Twist Grip Flight Idle. PNAC: Roger, Twist Grip is Flight Idle Recovery FTI 10 to 15 AGL, coordinate up collective and forward cyclic to slow the rate of descent and lower the
noce to level attitude. Maintain heading with the pedals. Verbals PAC: 10-15 Pull, Pause, Level Power Recovery PAC: 5 Taxi, Taxi, Taxi Full Auto PAC:5 Cushion, Cushion, Cushion. Low Rotor RPM Recovery
At 15 to 20, crack open the throttle slightly, lower the nose toward a level attitude and simultaneously increase the collective, bleeding rotor rpm no lower than 90%; smoothly rotate the twist grip to the full open position.

Know your variables. Instruct to the variables for that day. Relate FTI procedures through technique. Make the Field, Calibrate your eyes. Questions? Future Auto Fly Day March/April Time Frame HT-18 Standardization Training North of Tree Field No longer the wild west 20 January 2015
LT Jonny DOZER Kane CAT 1 STAN O North of Tree Field Why? At least 17 HAZREPs documenting slow to spool events Causal factor in recent Class-B mishap The fields in the channel suck Tree Field unavailable for simulated engine failures at altitude R+I 14-17 (Dated 14 NOV 14)
This is how we do it now Clarifying wave-off procedures 02/24/2020 "Warriors Train Here" 36 North of Tree Field Proficiency: When was the last time you flew a full auto? Are you targeting specific areas or the field in general or rolling it to Flight Idle and hoping for the best?
Are you sure you can make the field? If you are not confident, snivel for a QIP in a Bravo or with someone who is comfortable operating up there 02/24/2020 "Warriors Train Here" 37 North of Tree Field Normal flow of traffic or The Loop Fly North from Tree Field to Pistol Field East to Antenna Field
South to Utah Field West to intercept the power lines and then turn south When abeam Tree Field, turn west to split Tree Field Dont worry there will be a picture soon Peanut field is not a thing Dropping in Aircraft shall only execute one EP to each field then move to the next in the rotation Working Antenna is not a thing
02/24/2020 "Warriors Train Here" 38 North of Tree Field Wave-offs (power on or off does not matter) Wave-offs from fields after Simulated Emergencies at Altitude shall be executed away from the flow of traffic Once safe lateral separation has been attained and interval IDed, turn to parallel but heading the opposite direction Re-intercept course rules from a perpendicular heading behind your interval
Aircraft shall only execute one EP to each field then move to the next in the rotation. 02/24/2020 "Warriors Train Here" 39 Antenna Field North of Tree Field Pistol Field
