14 CFR Ch. I (1–1–19 Edition) 

Pt. 60, App. A 

beyond the first indication of a stall (such as 
stall warning system activation, stick shak-
er, etc.) in an FAA approved training pro-
gram. 

2. The evaluation requirements in this Di-

rective are intended to validate FSTD fidel-
ity at angles of attack sufficient to identify 
the stall, to demonstrate aircraft perform-
ance degradation in the stall, and to dem-
onstrate recovery techniques from a fully 
stalled flight condition. 

3. After March 12, 2019, any FSTD being 

used to obtain credit for full stall training 
maneuvers in an FAA approved training pro-
gram must be evaluated and issued addi-
tional qualification in accordance with this 
Directive and the following sections of Ap-
pendix A of this Part: 

a. Table A1A, General Requirements, Section 

2.m. (High Angle of Attack Modeling) 

b. Table A1A, General Requirements, Section 

3.f. (Stick Pusher System) [where applica-
ble] 

c. Table A2A, Objective Testing Require-

ments, Test 2.a.10 (Stick Pusher Force 
Calibration) [where applicable] 

d. Table A2A, Objective Testing Require-

ments, Test 2.c.8.a (Stall Characteristics) 

e. Table A2A, Objective Testing Require-

ments, Test 3.f.5 (Characteristic Motion 
Vibrations—Stall Buffet) [See paragraph 4 
of this section for applicability on pre-
viously qualified FSTDs] 

f. Table A3A, Functions and Subjective Test-

ing Requirements, Test 5.b.1.b. (High Angle 
of Attack Maneuvers) 

g. Attachment 7, Additional Simulator Qual-

ification Requirements for Stall, Upset 
Prevention and Recovery, and Engine and 
Airframe Icing Training Tasks (High Angle 
of Attack Model Evaluation) 

4. For FSTDs initially qualified before May 

31, 2016, including FSTDs that are initially 
qualified under the grace period conditions 
as defined in § 60.15(c): 

a. Objective testing for stall characteristics 

(Table A2A, test 2.c.8.a.) will only be re-
quired for the (wings level) second segment 
climb and approach or landing flight condi-
tions. In lieu of objective testing for the 
high altitude cruise and turning flight 
stall conditions, these maneuvers may be 
subjectively evaluated by a qualified sub-
ject matter expert (SME) pilot and ad-
dressed in the required statement of com-
pliance. 

b. Where existing flight test validation data 

in the FSTD’s Master Qualification Test 
Guide (MQTG) is missing required param-
eters or is otherwise unsuitable to fully 
meet the objective testing requirements of 
this Directive, the FAA may accept alter-
nate sources of validation, including sub-
jective validation by an SME pilot with di-
rect experience in the stall characteristics 
of the aircraft. 

c. Objective testing for characteristic mo-

tion vibrations (Stall buffet—Table A2A, 
test 3.f.5) is not required where the FSTD’s 
stall buffets have been subjectively evalu-
ated by an SME pilot. For previously 
qualified Level D FSTDs that currently 
have objective stall buffet tests in their ap-
proved MQTG, the results of these existing 
tests must be provided to the FAA with the 
updated stall and stall buffet models in 
place. 

d. As described in Attachment 7 of this Ap-

pendix, the FAA may accept a statement 
of compliance from the data provider 
which confirms the stall characteristics 
have been subjectively evaluated by an 
SME pilot on an engineering simulator or 
development simulator that is acceptable 
to the FAA. Where this evaluation takes 
place on an engineering or development 
simulator, additional objective ‘‘proof-of- 
match’’ testing for all flight conditions as 
described in tests 2.c.8.a. and 3.f.5.will be 
required to verify the implementation of 
the stall model and stall buffets on the 
training FSTD. 

5. Where qualification is being sought to 

conduct full stall training tasks in accord-
ance with this Directive, the FSTD Sponsor 
must conduct the required evaluations and 
modifications as prescribed in this Directive 
and report compliance to the NSPM in ac-
cordance with § 60.23 using the NSP’s stand-
ardized FSTD Sponsor Notification Form. At 
a minimum, this form must be accompanied 
with the following information: 

a. A description of any modifications to the 

FSTD (in accordance with § 60.23) necessary 
to meet the requirements of this Directive. 

b. Statements of Compliance (High Angle of 

Attack Modeling/Stick Pusher System)— 
See Table A1A, Section 2.m., 3.f., and At-
tachment 7 

c. Statement of Compliance (SME Pilot 

Evaluation)—See Table A1A, Section 2.m. 
and Attachment 7 

d. Copies of the required objective test re-

sults as described above in sections 3.c., 
3.d., and 3.e. 

6. The NSPM will review each submission 

to determine if the requirements of this Di-
rective have been met and respond to the 
FSTD Sponsor as described in § 60.23(c). Addi-
tional NSPM conducted FSTD evaluations 
may be required before the modified FSTD is 
placed into service. This response, along 
with any noted restrictions, will serve as in-
terim qualification for full stall training 
tasks until such time that a permanent 
change is made to the Statement of Quali-
fication (SOQ) at the FSTD’s next scheduled 
evaluation.
